This report was created from field data collected by personnel of the US Forest Service (USFS) and Oregon Natural Heritage Program (ONHP). The area examined encompasses four National Forests (Gifford Pinchot, Willamette, Mt. Hood, and Siuslaw) and two Bureau of Land Management Districts (Salem and Eugene).

Aquatic Dicotyledons of North America: Ecology, Life History, and Systematics brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic plants. Most books on aquatic plants have a taxonomic focus and are intended primarily for identification. Instead, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference materials. Included dicotyledon species are those having an obligate (OBL) wetland status, a designation used in the USACE National Wetland Plant List. Recent phylogenetic analyses are incorporated and rationale is provided for interpreting this information with respect to species relationships. This diverse assemblage of information will be useful to a wide range of interests including academic researchers, wildlife managers, students, and virtually anyone interested in the natural history of aquatic and wetland plants. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. This book is an essential resource for assisting with wetland delineation.

This book brings together information on the natural history, ecology and systematics of North American aquatic monocotyledons. The book is an overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference sources. Information on more than 300 species in 87 genera of monocotyledons will be included. Recent phylogenetic analyses will be incorporated. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. Key Selling Features: The primary source of natural history information on aquatic plants Comprehensive lists of ecological associates Synthetic overview of systematic relationships of aquatic species and genera Practical information for rare and invasive plant managers Essential guide to facilitate wetland delineation
