Plant Identification Resources

In order to effectively perform lake sampling using the Lake Vegetative Index (LVI), it is imperative to know the aquatic plants that are likely to be encountered. This page is intended to be a repository for helpful information to use in the identification of commonly encountered aquatic plants. It is NOT intended to replace the need for more formal field and classroom training.

Stream Bioregions

U.S. EPA (1992) defines ecoregions and subecoregions as areas "within which there is an apparent homogeneity in a combination of geographic characteristics that are likely to be associated with resource quality, quantity and type of stresses." Regionalization was performed as a collaboration among DEP, water management districts and the U.S. EPA Environmental Research Laboratory in Corvallis, Oregon.
