0:12

rain falls as it always has

0:15

but the landscapes that receive it the

0:18

path rain takes

0:20

the speed at which it runs off have

0:22

changed dramatically

0:24

[Music]

0:29

consider water's way throughout the vast

0:33

basin of chesapeake bay

0:36

some 40 rivers and

0:38

thousands of creeks feeding the great

0:40

estuary from across nearly a sixth of

0:43

the east coast

0:46

this is the watershed

0:48

every drop of rain that falls on 64 000

0:51

square miles heads one way bayward

0:55

and the chesapeake which appears so long

0:58

and broad

0:59

is in context just a smallish and

1:02

shallow pool of water on the receiving

1:04

end of everything 18 million people

1:08

in six states in the district of

1:10

columbia do with the land for good or

1:13

ill

1:15

technological controls on bay pollution

1:17

from sewage autos and factories

1:21

have made modest progress

1:24

but it's clear this will not be enough

1:26

to achieve a healthy bay

1:29

further progress must come from the

1:31

lands of the watershed from better

1:34

understanding of what was water's way

1:37

in the chesapeake basin when the bay was

1:40

clearer cleaner healthier

1:43

[Music]

1:49

the title of this film derives

1:51

from a man who shot a wolf on a mountain

1:53

in arizona a century ago

1:57

also from a beaver i executed much more

2:00

recently on a tidal tributary of the

2:03

chesapeake

2:04

neither aldo leopold nor i yet grasped

2:07

the wisdom of the natural landscape we

2:10

did not think ecologically

2:13

leopold would become known as the father

2:16

of wildlife ecology

2:19

but back in his trigger happy days like

2:21

most hunters of his era

2:23

he thought that fewer wolves meant more

2:25

deer that no wolves at all would mean

2:28

hunter's paradise

2:30

years later he re-evaluated this in a

2:32

classic essay called thinking like a

2:35

mountain only the mountain has been

2:37

around long enough to know what the howl

2:39

of a wolf really means

2:41

and that

2:43

deer run in mortal fear of the wolf

2:46

but the mountain is in mortal fear of

2:48

the deer and the idea of that is that if

2:51

you take wolves out of the landscape the

2:53

deer population increases

2:56

and they start to eat everything around

2:58

them

2:59

and then hence we have more erosion we

3:01

have less food and cover for other

3:03

wildlife

3:04

[Music]

3:09

while beavers are not predators

3:12

you can make a similar argument

3:14

that preserving a creature that people

3:16

eradicate is a critical part of

3:18

preserving a healthy diverse

3:21

rich biological ecosystem and natural

3:24

environment

3:26

i only saw my hapless beaver as a sharp

3:29

toothed rodent chiseling down newly

3:31

planted trees

3:33

threatening to dam up the creek and

3:35

flood my newly acquired property

3:38

i did not appreciate how her species for

3:41

thousands of years

3:43

had transformed the north american and

3:45

chesapeake landscape to an extent

3:48

rivaled only by modern humans and in a

3:50

profoundly more affirming way

3:54

i was not thinking like a watershed

3:58

millions of beaver ponds and dams once

4:01

sponsored a lush mosaic of wetlands

4:04

throughout the chesapeake region

4:06

these slowed and spread and retained

4:09

water flowing to the bay from every

4:11

creek and river

4:12

letting it soak in and percolate through

4:15

the ground

4:16

this bay of beavers damped the flooding

4:19

of the fiercest storms elevated the

4:21

water table to feed creeks through seeps

4:24

and springs during the worst droughts

4:27

lent a resilience and stability to the

4:30

whole system

4:32

this pre-colonial landscape was not just

4:34

greener more forested than today's it

4:37

was wetter

4:38

a watershed more accurately described as

4:42

a water keep

4:46

and these lavishly beavered lands

4:48

afforded splendid habitat with all

4:51

manner of fish and fowl and amphibians

4:56

the water that slowly escaped to the bay

4:58

through forests and wetlands was clean

5:01

and clear beyond present day imagining

5:04

because beavers have been gone so long

5:07

we trapped them out of the chesapeake

5:09

watershed by 1750

5:12

there's almost an ecological amnesia

5:15

as to the the benefits they conferred

5:18

the world they created to how the

5:21

watershed in effect thought

5:25

modern humans have thought so very

5:27

differently

5:29

creatures the dry land we embrace the

5:32

straight line and live at right angles

5:34

to the earth we pave and channel ditch

5:37

and drain

5:38

the faster rain swooshes off our

5:40

cityscapes and crop lands the better no

5:43

time for water to soak in recharge the

5:46

shallow aquifers

5:48

the upshot has been a massive load of

5:50

sediments and fertilizers and chemicals

5:53

to the chesapeake estuary which has

5:55

become murky and devoid in oxygen as a

5:58

result

6:00

water's way gets simplified

6:02

nature's symphony moves towards single

6:05

loud notes

6:06

stability and resilience and biological

6:09

diversity are diminished flood and

6:12

drought are exacerbated

6:17

one two three in the 1970s grace brush a

6:21

paleo ecologist at johns hopkins

6:24

university we have a kit that extracts

6:26

dna began to extract yards-long muddy

6:29

cylinders from the bay's bottom

6:31

sediments

6:32

unlocking a whole library of the

6:35

estuaries past a record going back a

6:38

thousand years and more

6:40

oh that's great sediment is always being

6:43

eroded off the land and it gets

6:45

deposited in wet areas ponds lakes

6:48

estuaries and so on

6:51

and it just piles up

6:53

year after year after year

6:56

so each one of those layers of sediment

6:59

contains

7:00

what i'm calling hydroglyphics here but

7:03

they're really actually fossils fossils

7:05

of small animals fossils of pollen

7:08

grains seeds many many

7:11

entities that get preserved in that

7:13

sediment

7:14

at a certain depth in the core for

7:16

example a shift from oak to ragweed

7:20

pollen corresponded to the beginnings of

7:22

colonial agriculture as forests gave way

7:26

to the ax and the plow

7:28

similarly shifts from pollens of swamp

7:31

plants to dry land plants

7:34

showed the drying out of the beavered

7:36

landscape as humans trapped them for fur

7:40

after we began to accumulate some

7:43

evidence from the sediment cores

7:46

we began to integrate that into some

7:47

pictures of what the bay might look like

7:51

in the pre-colonial time it was forested

7:54

and it had all of these wet areas many

7:57

of them created by these beavers

8:00

by the late 17th

8:02

to the early 18th century the beavers

8:04

were gone

8:06

then we get to the late 19th to early

8:08

20th century and that's when

8:11

80 of the forests were deforested

8:15

so we have

8:16

a lot more forest now than we had in the

8:18

early 1900s

8:20

but there's still a lot of agricultural

8:22

land

8:24

and also paving has started so this land

8:27

that is

8:28

not forested is paved a lot of hard

8:32

surfaces

8:33

so you're getting a lot more runoff into

8:35

the bay this transformation of its

8:37

watershed led directly to today's

8:40

degraded chesapeake bay

8:42

whose astoundingly shallow water

8:45

drains a region from new york nearly to

8:47

north carolina and as a result is more

8:51

impacted by land use than any comparable

8:53

body of water on earth

8:57

instead of the water seeping through a

8:59

forest floor of litter

9:01

and leaves and twigs and so on the water

9:04

now is just flowing off

9:07

on these hard surfaces

9:09

and going into the estuary and carrying

9:11

with it

9:12

many many

9:14

substances fertilizers sediment and so

9:16

on

9:17

[Music]

9:21

if i were the chop tank the eastern

9:23

shore's biggest river

9:25

it's on nick carter's place i'd want to

9:27

be born to start my journey to the bay

9:31

nick has spent nearly half a century

9:33

renaturing his patch of the watershed

9:36

it's one of many places the shop tank

9:39

gets its start but it is the very nicest

9:42

nick does think like a watershed

9:46

in fact you can step off this driveway

9:49

where we're now walking step off just a

9:52

few feet and you'll find how much softer

9:56

how much more pervious

9:58

that ground is you can feel it as soon

10:00

as you step off exactly amazing this is

10:04

what the earth ought to feel like

10:06

without the influences of man

10:10

this is

10:11

exemplary

10:12

of everything

10:14

from the mississippi to the atlantic

10:16

coast

10:17

as it was before the europeans got here

10:21

all the tributaries to the bay

10:23

were shielded and guarded and stabilized

10:26

by the forest

10:29

without this

10:30

foreign

10:32

far greater transmission of water

10:35

so the more water you got running off

10:37

the more nitrogen you lose the more

10:40

phosphorus you lose

10:42

the phosphorus and nitrogen and the

10:44

runoff from the land cause explosive

10:46

growth of algae in the bay that blocks

10:49

light and consumes oxygen both of these

10:52

harmful to aquatic life

10:54

those nutrients if retained on the land

10:57

build fertility support life and

11:00

splendid diversity

11:02

in those early days before colonization

11:06

when we had a very wet watershed

11:09

the watershed was taking care of the

11:11

nitrogen it was recycling the nitrogen

11:15

and so

11:16

once that was

11:18

drained you had all of this nitrogen no

11:21

longer going back into the atmosphere

11:23

but just being washed off into the bay

11:27

you could cut down a tree you can plant

11:29

a new tree but it's going to be 10 to 12

11:31

years

11:32

minimum before it's going to produce

11:34

seeds and start a new generation

11:37

so the thing that happened

11:39

with the clearing of the forest

11:43

was that you had

11:44

eventually only these organisms like

11:47

dandelions on the land that that have a

11:50

generation time of a year so they'll

11:52

just come back and come back and the

11:54

same in the water the fish and crabs and

11:58

so on that have a long generation time

12:01

of years

12:02

they just can't make it

12:05

they're replaced

12:06

by these

12:08

very small organisms bacteria

12:11

diatoms

12:14

and so on one cell that have a

12:16

generation time of a day or a few days

12:19

and that was a terrific change

12:22

i said this transformation of the land

12:25

from forest to farms and hard services

12:29

and the rapid rate at which it occurred

12:31

was one of the great ecological

12:33

phenomena in human history it would have

12:36

enormous repercussions for the estuary

12:39

that drained these altered lands

12:41

so it was an enormous change in a very

12:45

short period of time

12:47

development nowadays comes with a host

12:49

of mandatory controls to mitigate the

12:52

quantity and quality of the storm water

12:54

caused by more paving

12:57

more intense rainfalls driven by climate

12:59

change lend an urgency to this

13:03

ellicott city gets a combination of

13:05

river flooding from the patapsco river

13:08

that runs

13:09

right at the top of it but it also has

13:12

watershed flooding

13:14

from the three square miles of urban

13:16

development

13:18

upstream in 2016 and 2018

13:22

we had storm events that dropped about

13:24

six inches of rainfall in less than two

13:27

hours

13:28

in each case they were

13:30

thunderstorms and just kept training

13:32

over the same area

13:36

and the streams couldn't handle it and

13:39

so it went overground and ran down the

13:42

street to a depth of five to six feet

13:45

washing hundreds of cars into the

13:47

patapsco

13:48

and regrettably the loss of the several

13:51

lives between the two floods

13:56

it devastated the downtown

13:59

business district and closed for many

14:01

months while they were

14:03

trying to repair the basic

14:05

infrastructure

14:07

hiking the slopes above ellicott city

14:10

schuler explains how local development

14:13

has degraded a small stream and

14:15

contributed to the flooding

14:17

if you have really good eyes you can see

14:19

the

14:20

sewer manhole stack

14:23

in the foreground right there which was

14:25

never intended to be put in the middle

14:26

of the stream so all that sediment

14:28

erosion has eroded and gone down to the

14:32

river

14:33

again being pushed by that powerful

14:35

force of urban storm water and this sort

14:38

of single thread stream that we see

14:41

in modern times

14:43

is not what we would see back then we'd

14:45

see a multiple thread stream with a lot

14:47

of different shoots and

14:50

things like that

14:51

a lot of our scientists are revealing to

14:54

us

14:55

what those

14:57

historic streams were like that are just

14:59

a lot different from what we see

15:01

in 2021

15:03

so we're on the banks of the new cut now

15:05

and this gives you a good sense of what

15:07

we contend with here in the watershed

15:09

which is a willingness to pave and

15:12

develop right up to almost the very

15:14

banks of these streams as they descend

15:17

down into main street ellicott city

15:20

and maybe one or two developments that

15:22

doesn't make a difference but this is a

15:24

death by a thousand cut

15:26

a thousand new cuts on this new cup

15:29

branch and the consequence of that over

15:32

and over again along the length of every

15:34

single one of these streams that ends

15:36

and bottoms on main street

15:38

is devastating

15:41

there is a fatalistic approach to the

15:43

old ellicott city watershed that is we

15:45

have destroyed this watershed to such an

15:48

extent that you should allow us to

15:49

continue to destroy that last little bit

15:52

of it that's left those last forested

15:54

acres those last steep slopes that last

15:57

stream bank that's not already scoured

15:59

covered in riprap destroyed that

16:01

non-functional floodplain

16:04

as we studied a lot of streams we

16:07

realized that very low levels of

16:09

impervious cover somewhere around 5 to

16:12

10 percent

16:14

in a watershed was enough to begin

16:17

degrading and diminishing the quality

16:20

of urban streams and to put 10 percent

16:24

in perspective that's pretty

16:27

rural development like one acre lot

16:30

subdivisions

16:32

and after about 25 percent impervious

16:35

cover

16:37

much of stream health degrades uh

16:40

completely we call them non-supporting

16:42

streams

16:44

baltimore washington dc are like 70 to

16:47

80 impervious cover

16:50

again that iron law of imperviousness is

16:53

very hard to repeal

16:56

the

16:56

sheer magnitude of the impacts are

16:59

really hard to

17:01

fix

17:02

with one practice

17:04

and so we have to take more of a

17:07

holistic

17:08

watershed approach

17:10

where we try to

17:12

restore all the elements that make

17:15

an aquatic ecosystem work the riparian

17:19

forests

17:21

the wetlands along the stream corridor

17:24

in some cases

17:26

the stream

17:28

itself

17:29

so that's kind of the challenge that we

17:31

face now in the next generation of how

17:34

we can bring back

17:36

our urban streams

17:38

and make better progress against the

17:40

ravages of impervious cover

17:44

agricultural lands across the bay

17:46

watershed have shrunk dramatically often

17:49

because of development in the last

17:51

century

17:52

but the intensity of farming has leaped

17:55

as chemical fertilizers pesticides and

17:58

weed killers per acre have multiplied

18:01

also the manure from animal operations

18:04

that have grown larger and more

18:06

concentrated

18:07

the sheer extent of agriculture and its

18:10

intensity have made it the single

18:13

largest source of bay pollution

18:16

in recent decades farmers have begun to

18:19

surround their fields with forested

18:21

buffers and wetlands

18:23

and border their ditches with vegetative

18:26

cover to intercept the movement of

18:28

sediment manure and chemicals into

18:30

waterways

18:32

yeah i'm trey hill i own and operate

18:34

harborview farms with my father we have

18:36

farms that we till in talbot county kent

18:38

and cecil counties

18:40

i'm a strong believer in the buffers

18:43

a buffer is is trying to take land out

18:45

of production that's really close

18:47

to environmentally sensitive areas

18:49

the easiest example that would be like

18:50

if you're farming next to a river

18:52

with the conservation services done

18:55

they'll pay us rent

18:57

on land if we take a certain amount of

18:59

that out of production

19:01

and what they'll do is they'll also pay

19:02

us to plant native vegetation

19:05

switch grass big blue stem little blue

19:07

stem things like that that have really

19:09

deep root systems

19:10

and we don't fertilize it so it's

19:12

wildlife habitat but also when anything

19:14

comes off the field it acts as a filter

19:16

before it goes to the river

19:19

winter plantings of so-called cover

19:22

crops is another practice farmers are

19:24

adopting to reduce runoff

19:27

cover crops are sown to suck up

19:29

fertilizers still in the shallow

19:31

groundwater after cash crops are

19:33

harvested

19:34

keep nitrogen and phosphorus from

19:36

running into the bay

19:39

similarly planting without plowing to

19:41

minimize runoff is becoming widespread

19:45

since agriculture first started people

19:47

have tilled the soil to take care of

19:49

weeds

19:50

in other words when you run a rotary hoe

19:52

in your garden for example now when we

19:54

plant our crops we don't do that at all

19:56

we plant into soil just as it is by not

19:59

loosening that soil by not disturbing it

20:01

we get a lot less erosion a lot less

20:03

runoff yeah people ask me how much

20:06

farther can we go how much better can we

20:08

be at environmental cleanup

20:11

and it's easy for me to think that we've

20:13

we've finished right we're at the end of

20:15

the road like we've done everything we

20:16

can do

20:17

but then i think back to when i was 30

20:20

and i thought the same thing

20:22

and the way i farm now

20:24

is completely different than i did 15

20:26

years ago

20:27

so all i can do is hope that 15 years

20:30

from now i'm farming completely

20:31

different than i am now

20:34

[Music]

20:38

my husband robert fry and i run st

20:40

bridget's farm in kent county

20:42

kennedyville maryland it's 62 acres we

20:45

milk 60 jersey cows with a robot which

20:48

we put in three years ago

20:50

when we bought the farm it was all in

20:52

wheat and it had been a rotational

20:53

standard wheat bean corn

20:56

system we tried to grow some corn silage

20:58

for a year we grew some annuals but

21:00

after many failed experiments we decided

21:02

to put everything into permanent pasture

21:04

everybody knows that permanent pasture

21:06

is the best practice for water quality

21:09

and

21:10

erosion control and so you have a living

21:13

root year round

21:15

there's no bare soil

21:17

if there's a water event we have a

21:19

culvert that goes down along our fence

21:20

line

21:21

and you can literally see the water from

21:24

our land is clear and the water from the

21:26

tilled the ground is brown

21:29

and it's clear as day

21:30

we have about

21:32

19 paddocks in this

21:34

this section of fields about a little

21:36

over 20 acres so the reason to separate

21:38

the paddock is to promote soil health

21:41

really you don't want to have the cows

21:42

grazing the new growth all the time

21:45

we've just been destroying soil for

21:47

years we haven't been replenishing soil

21:49

when my dad was farming in the 50s they

21:51

never talked about it and it's only been

21:53

recent that people started talking about

21:55

soil health okay let's go the economic

21:57

system in which we are working rewards

22:00

uniformity simplicity speed

22:03

and size

22:05

it doesn't reward supporting beaver dams

22:09

it doesn't reward

22:11

doing things to get more birds on your

22:13

farm

22:15

the wrong things are being rewarded in

22:17

our system

22:18

some of the earliest signs of

22:20

agriculture's impact on the bay and

22:23

grace brush's sediment course

22:25

involved ditching to drain croplands

22:28

turning streams and swamps into straight

22:30

channels designed for a single purpose

22:33

it was

22:34

amazing

22:36

that that pollen

22:38

changed

22:39

from totally wet plants

22:42

to almost entirely dry plants almost

22:45

immediately at the time of colonization

22:48

the land became dry very quickly

22:52

and that's when i began to look at the

22:54

ditches

22:56

that changed the land very very quickly

22:59

and also

23:01

uh changed the water very quickly

23:03

because then you got all this stuff

23:04

coming into the bay very very quickly

23:09

generally farmers like to see water move

23:11

off the land but in a ditch project like

23:13

this we're trying to do both so it's

23:16

designed in a way to hold and convey

23:19

water in a way that doesn't hurt crops

23:21

growing will also achieve our water

23:23

quality and also habitat goals i mean

23:25

we're

23:26

literally 500 yards from an active farm

23:28

field

23:29

and transitioning from a ditch to a

23:32

natural stream channel

23:36

i often take my students on a special

23:39

part of the nanticoke river

23:41

to illustrate water's way the human

23:44

approach versus nature's

23:46

the river one of the wildest and

23:48

loveliest in the bay begins as a

23:50

man-made ditch constructed to perform

23:53

one vital duty

23:55

quickly draining storm water off the

23:57

flat corn and bean fields of the

24:00

watershed

24:02

we are just now leaving the ditch the

24:05

straight line the single purpose

24:08

just beginnings of seeing nature

24:10

reassert itself

24:12

but where ditch maintenance stops

24:15

the universal tendency of free-flowing

24:17

water to wander to curve and loop

24:20

quickly asserts itself you see how those

24:22

branches start to catch debris and

24:25

that'll form a little

24:27

jut out that'll cause the water to start

24:30

to bend and

24:32

start to return it to its natural shape

24:37

here the meandering complex river serves

24:40

no one purpose just promotes life and

24:43

all its beauty and diversity nature

24:46

comes back pretty quick if you let it go

24:51

not far off on the pocomoke river

24:54

there's been another encouraging

24:56

reconciliation

24:58

this impressive restoration by the

25:00

nature conservancy along with state and

25:03

federal agencies

25:04

has leveled old dikes to reconnect the

25:07

river with nearly seven square miles of

25:09

flood plain wetlands humans acting like

25:12

beavers

25:13

spreading the water out letting it take

25:16

its time to the bay

25:18

so the goal is to bring the flood plain

25:20

elevation which is back here straight

25:22

across

25:23

so that when we get the storm events the

25:25

the water has the opportunity to go into

25:27

the flood plain filter in there during

25:29

the event so the breaches act as the

25:32

inlet outlet during the storm events

25:35

it was channelized in the 30s and 40s

25:37

for agriculture purposes so the farmers

25:38

in the area could drain their bag fields

25:40

quicker

25:41

we're allowing it to kind of act and

25:43

meander like it did once 70 years ago

25:46

you know we're permanently protecting

25:48

land we're increasing habitat we're

25:50

increasing water quality so everything

25:52

that had the opportunity to go out to

25:54

the bay before now has the chance to

25:56

come in here on field trade before it

25:58

gets into our system and now listen to

26:00

the chesapeake

26:02

another example of helping water relearn

26:04

its natural ways

26:06

is on the smithsonian environmental

26:08

research center's large tract of forest

26:11

and wetlands on the rhode river south of

26:14

annapolis maryland

26:16

so this is muddy creek the north branch

26:19

of muddy creek this

26:20

channel here

26:22

was deeply incised i was cut down it

26:25

looked like a drainage ditch

26:27

in some places there were 10 or 12 feet

26:30

between the flood plain and the bottom

26:32

of this stream channel

26:34

and the reason it got eroded like that

26:36

is because of the single culvert

26:39

that carries the water under the road

26:43

and you can see it looks kind of like a

26:45

big pool

26:46

before it looked like a drainage ditch

26:49

there's a berm that's been constructed

26:51

just downstream

26:53

of me

26:55

and that now deflects the water out over

26:58

this flood plain

27:00

and this this part was was dry before

27:03

now it's a wetland

27:08

about 80 percent of all the development

27:10

out there has been already done with

27:12

poor environmental practices

27:15

so we've been spending millions and

27:17

millions every year

27:19

to restore this restore the streams

27:21

retrofit storm water practices

27:25

create wetlands

27:26

get back some of those habitat

27:29

features we lost

27:31

it's a slow chugging train it's a huge

27:34

job it's multi-billions

27:37

and multi-decades to do

27:40

meanwhile we keep developing

27:45

we don't

27:46

need

27:48

expensive programs

27:51

to save the land and the day

27:55

you just need a whole lot less people

27:58

doing a whole lot less modification of

28:01

the land

28:03

what we let this land do

28:05

is about as low budget as you can

28:08

possibly get because it didn't cost us a

28:10

nickel to let this forest grow back up

28:17

we've lost more than half the

28:19

chesapeake's original wetlands

28:22

lost some 40 percent of its forests

28:26

forests and wetlands are the watersheds

28:28

least polluting land uses and they're

28:31

just beautiful

28:34

but thinking like a watershed doesn't

28:36

stop at the water's edge

28:38

on the bay's bottom the remaining one

28:40

percent of oysters are nowadays valued

28:43

for their services to clean water and

28:45

provide habitat in the reefs they build

28:48

no longer just regarded for the price

28:50

they fetch per bushel

28:53

similarly remaining meadows of

28:56

underwater seagrasses that struggle for

28:58

light in the modern murky bay

29:01

are now prized for providing oxygen and

29:03

for nurturing a variety of aquatic life

29:06

including blue crabs who seek their

29:09

protection to molt and grow

29:11

but putting all these ecosystem

29:14

valuations into protective restorative

29:17

action

29:18

remains very much a work in progress not

29:20

nearly enough

29:22

restoration goals set by federal and

29:24

state governments throughout the bay

29:26

watershed were badly missed in 2010

29:30

the revised deadlines set for 2025 are

29:33

by no means assured of success

29:38

the solutions going forward will

29:40

increasingly lie with the land with

29:42

learning to think like a watershed with

29:45

relearning water's old ways

29:47

rather than pushing it rapidly away

29:50

downstream

29:52

in reconfiguring the landscape and the

29:54

way it sheds water

29:56

slowly leanly cleanly clearly

30:00

lies the bay's future

30:03

lies our future

30:07

[Music]

30:12

could a small brained compulsive rodent

30:15

castor canadensis the beaver be a key

30:20

so we're in the long green creek

30:22

watershed

30:23

in baltimore county flows to the lower

30:25

gun powder and then eventually the lower

30:27

gun powder flows into the chesapeake bay

30:30

1993 this valley was a cow pasture

30:32

virtually no trees in sight there was no

30:35

shade for the stream the banks on this

30:38

stream were eroding in a sort of an

30:41

accelerated fashion so we got some small

30:43

grants to do some live staking where we

30:46

put willows and dogwoods into the stream

30:48

banks and some of them would sprout and

30:50

turn into trees

30:52

and way back when we didn't know it but

30:54

that was going to be beaver food later

30:56

on as those

30:57

willows matured

31:00

we put an easement on this ground the

31:01

landowners

31:02

set this aside as a natural area

31:05

for years after that they would trap the

31:07

beaver out um because

31:10

they thought that you know the beaver

31:11

eating the trees was a bad thing

31:14

over time

31:15

what we all started to find out was that

31:18

if you left the beaver alone there was

31:20

so much more wildlife here that's why

31:22

you call beaver the keystone species

31:25

everything else benefits by allowing the

31:27

beaver to come in and alter the

31:29

landscape

31:31

we installed a flow management device

31:33

which allowed some control to the land

31:36

owners about how deep this water was

31:38

going to get and how high the dams were

31:40

going to get

31:41

so it gave them some control

31:44

reduced the flooding on the farm road

31:46

and uh over the last three years we've

31:48

seen this area transform again and again

31:51

and again

31:52

as the beavers increase their numbers

31:55

and make this habitat you know what you

31:57

see today which is really sort of a

31:59

narnia type wetland for wildlife

32:04

i live in the catoctin mountains of

32:06

northern frederick county

32:08

we're at

32:09

1500 feet elevation here

32:13

the first beaver arrived

32:16

in march four years ago and that was

32:18

herbert and the first evidence was a

32:20

little dam where the pond overflows

32:24

14 months after he got here bieber came

32:26

dashing out of the thicket into the

32:29

wetland into the pond and

32:32

i thought that's not the way herbert

32:34

would normally act later on we realized

32:36

that was the female we named her

32:38

sherbert

32:40

the next spring they had three

32:44

baby beavers in the lodge they built

32:46

over there

32:48

and last year

32:50

they had three more babies in the lodge

32:52

they had on the island in this pond from

32:56

the very beginning of herbert arriving

32:58

here

32:59

you know i posted pictures of herbert

33:01

and then herbert and sherbert and the

33:03

babies and i tell you as much as i wish

33:06

that my posts on climate change and

33:08

other things got as much attention as

33:10

those do they have been the most popular

33:12

thing that i i post for the most part

33:16

there are just so many benefits to

33:19

having beavers for wildlife for water

33:21

quality they catch a tremendous amount

33:23

of sediment that would otherwise get to

33:26

the binoxi river or the bay

33:28

they clean and filter water they help to

33:31

recharge groundwater which keeps springs

33:35

active and flowing for more of the year

33:37

because of that

33:40

when we create a world that's better for

33:41

beavers it has

33:43

uh tremendous ancillary

33:45

benefits and impacts for human community

33:48

and society

33:50

i'm looking out at this beautiful pond

33:52

that was created in 1990

33:55

by some beavers that moved in

33:57

unexpectedly and built a dam

34:00

and they're long gone but

34:03

the pond remains

34:05

and we discovered that the the pond

34:09

and the beaver dam were stopping

34:11

nutrients and sediments from going down

34:14

the stream because we have a stream

34:16

monitoring station

34:17

that monitoring station was running

34:19

since the mid-1970s

34:22

the beaver dam was built in 1990 15

34:26

years after we started monitoring

34:29

and then we waited another five or ten

34:31

years and looked at the data and we

34:33

could see the effects of the of the dam

34:36

from comparing before and after and this

34:38

pond is still here

34:39

[Music]

34:46

living with beavers can take some effort

34:50

my wife cleo braver and i moved here in

34:52

around 1997

34:55

from baltimore

34:57

and just fell in love with the place

35:01

put in 18 acres of wetlands and 20 acres

35:05

of border of the fields and then turned

35:08

it into an organic vegetable operation

35:11

let a lot of the property

35:13

essentially go back to nature

35:16

the pond that we were by right here

35:19

was here when we got here

35:21

it was full of fish and and attracted a

35:24

lot of wildlife and eventually attracted

35:27

some beavers

35:30

we first started noticing small trees

35:34

disappearing

35:36

and

35:37

every now and then a little bit of a

35:38

larger tree and then we spotted them

35:42

the pipe is to keep the pond at a

35:45

certain level

35:46

and keep it from overflowing in big

35:48

rains

35:50

as i understand

35:51

there's only one thing a beaver can't

35:53

stand and that's flowing water

35:56

so

35:57

they would continue to block the pipe

36:00

i would unblock it

36:03

they would block it

36:05

i would unblock it

36:06

they would block it

36:08

i would unblock it

36:10

so far i've been keeping score

36:14

i think it's beavers about 100 and ali

36:16

about zero

36:18

we actually enjoy having the beavers

36:19

here and watching what they do

36:22

they're incredible little creatures

36:24

and uh incredibly busy

36:28

there's other resistance to beavers

36:30

trout enthusiasts as one example worry

36:34

that beaver ponds will raise

36:35

temperatures in the cold water that

36:37

their favorite sports species requires

36:41

as opposed to dams that we would

36:44

build

36:45

beaver dams are generally porous so

36:47

you've got water coming out of the

36:48

bottom

36:49

you've got water coming out of the

36:51

middle

36:52

you've got these side channels

36:54

which are great for fish passage

36:56

so

36:57

fish evolved with these beaver dams in

36:59

place so they're able to find these

37:01

little nooks and crannies through the

37:03

dam

37:04

you can even kind of shoot your hand all

37:06

the way through and get to the other

37:09

side so salmon and trout and other

37:12

species of fish

37:14

can get through these dams and you know

37:16

these gravels below the dam this is a

37:18

great spot for spawning

37:21

so i'm hoping that this dam increases in

37:23

size over time

37:25

and what that's going to do is shoot

37:26

water out across a greater width and

37:28

spread this energy out even more

37:32

there's a lot of places in frederick

37:34

county where beavers would happily move

37:36

into

37:37

streams that they would damn ponds that

37:39

they would move into but there's a

37:40

difference between that and places where

37:42

people welcome them

37:44

or or coexist with them and so there's

37:47

only two ways that that can happen one

37:50

is that you have areas that are big

37:52

enough and wild enough

37:54

so that beaver activity is part of a

37:58

bigger landscape in a five or ten

37:59

thousand acre park or something like

38:01

that or

38:03

people choose to put some effort into

38:06

coexisting with them and that's what

38:08

we've done here

38:10

between this area near our house and

38:12

pond and over where the other three

38:15

ponds are uh between this method some

38:19

other methods and chicken wire have

38:20

probably saved about

38:22

five or six hundred trees from the

38:24

beavers

38:25

so it's basically kind of the deal we've

38:27

struck with the beaver it's like

38:29

although really he's sort of forced to

38:31

comply

38:33

i save two trees which i walk by all the

38:36

time so i can reinforce it more if i

38:38

need to

38:39

and

38:40

they get all the rest of the beech trees

38:42

right around here

38:47

if we give beavers the space practice

38:49

peaceful coexistence

38:51

they will repay the favor with a better

38:54

bay than humans alone could ever achieve

38:56

or afford

38:58

it is no stretch to imagine a

39:00

science-based formula for giving

39:02

pollution credits or cash payments to

39:05

landowners who welcome beavers

39:09

we're on winless run

39:10

in baltimore county

39:12

this is a urban watershed

39:15

seen a lot of development in the

39:17

watershed over the last 20 years

39:20

the beaver

39:22

may have come in from the the bay they

39:24

may have come in from white marsh run

39:27

but they found this habitat ideal

39:29

and as you can see they've they've made

39:31

quite a home here

39:32

the pond is 10 to 20 acres in size think

39:35

about it this pond

39:37

treats all this urban runoff all the

39:39

same runoff that we're spending

39:41

you know millions if not billions of

39:43

dollars

39:44

to try and mitigate and improve water

39:46

quality in the chesapeake bay

39:50

and the beavers are here doing a lot of

39:52

that heavy lifting for us for free

39:55

and it makes a lot of sense to me as a

39:57

you know someone who's been in the

39:58

restoration

40:00

uh practice for the last 30 years that

40:03

maybe the answer to restoring the bait

40:05

doesn't include a lot of rocks and logs

40:07

and man-made ponds but just sort of

40:10

honoring the ecosystem services

40:12

of

40:13

this furry little rodent who used to be

40:15

here in the millions but was trapped out

40:18

you know way back when before

40:21

any of us ecologists were walking around

40:22

the landscape taking notes

40:25

so if you think about it you know

40:27

beavers

40:28

are really

40:30

they're really a big part of our history

40:32

in this country but they're not part of

40:34

our culture

40:38

learning to appreciate and live with a

40:40

creature whose ecological vision

40:42

diverges from our own

40:44

will require us to think more like a

40:46

watershed to understand what was once

40:50

water's preferred way upon and through

40:52

the landscape

40:54

and how that translated into a

40:56

chesapeake now imperiled by near amnesia

40:59

of what once was

41:02
