- Vaucheria grows
on moist sand, soil, and salt marsh banks, sometimes forming
dark green mats, or is found submerged in shallow freshwater
or marine environments. It is common in streams, rivers, ponds,
lakes, ditches, and seeps. Growths are especially abundant in
waters with high nutrient levels, such as downstream habitats
affected by runoff and nutrient loading from human land use.
The genus is most often found in the cooler months between fall
and late spring, and has been collected from habitats under ice.
Some species are habitat-specific, inhabiting only shallow lakes
and ponds or the mud of ditches and bogs, while others are known
from diverse habitats. The genus has been collected in much of
the continental United States, as well as in Puerto Rico and
Trinidad.
