Information on Beavers
The beaver (Castor canadensis) is North America's largest rodent and lives in Lake Vilbig.
Beaver will cut any tree, but seem to be fond of the prettiest trees they
can find. Some states protect beavers while others classify them as pests.
These industrious creatures cause millions of dollars in damage annually.
Their dams and burrows flood highways, collapse reservoir dams, and derail trains.
Beavers can block a 12-inch culvert in twenty minutes. Beavers are also the
main carriers and promoters of Giardia. Giardia is an intestinal disease transmitted
in water to humans (refer to the "Texas Sportsman", Dec 1990 issues for more on
Giardia and beavers)

Information on Nutria
The Nutria is a large rodent with a long, scaly, rat-like tail and webbed hind feet.
Nutria are herbivores, feeding only on plants. They reproduces so fast that they soon exhausts the food supply around the ponds,
and move into areas where they are not wanted. Nutria eat cattails, reeds and other water plants. They dig into the marsh soils to eat the basal and
root portions of the plants. Their feeding activity kills the marsh vegetation. The roots of the marsh vegetation binds
the soft organic marsh soils together. When this root fabric dies, the soils become susceptible to erosion. Lake Vilbig has a large population
of these rodents.

Information on Cormorants
The Cormorant, a prehistoric species of bird with long, snake-like neck. Cormorants are awkward fliers but skillful swimmers, catching bass, crappie, bluegill, and shad. They can often be seen near water holding out their wings to dry. The Chinese used these birds to help them catch fish by putting rings around their necks, which prevent them from swallowing a fish. They cause great damage to the fish populations on Lake Vilbig, often injuring fish too big to swallow. The big fish that somehow survive the onslaught have battle scars across their backs from hook like beaks of these birds. Swarms of these birds start appearing on our lake around November and don't leave until April.
