Guide for Developing Integrated Aquatic Vegetation Management Plans in Oregon

Abstract

This manual focuses on controlling nuisance aquatic plants, occurring in Oregon lakes. To use this manual, it is necessary to distinguish between an aquatic plant problem, and a water quality enrichment problem that typically results in excessive algae production (See Box this page). The most serious type of aquatic plant problem is caused by invasion of a waterbody by a non-native species. Non-native weed invaders may flourish in suitable conditions and degrade habitat and other beneficial uses. The biology and ecology of weeds allows them to fluorish under a wide range of conditions. Nutrient enrichment is not a prerequisite for aquatic weed problems. Illustrations by Ruth Gothenquist, Plant drawings by IFAS Center for Aquatic Plants and Wisconsin Lakes Partnership.
