Managing your wetland: |
Green tree reservoirs |
Requirements |
page 2 of 4 |
Although green tree reservoirs can vary widely, most have
the following attributes in common. |
|
Bottomland hardwoods (oaks, gums, ashes) at least 40
years old. A
minimum of 10 acres.
A relatively flat
area.
Soils with good
water holding capability - impervious clays are
best.
Proximity to
traditional waterfowl wintering grounds and flight
paths.
Dependable water
supply |
|
Potential
sources are: a nearby water storage reservoir at
a higher elevation; pumping ground water or
surface water (nearby stream or pond); natural
rainfall and drainage; and temporary diversion
or blockage of minor streams. Using water from a
storage reservoir or collecting rainfall and
runoff are the best alternatives; however,
during some years these preferred methods may
not provide enough water. |
A series of dikes and
levees to control water levels. |
