Ecoregional Planting Guides (for pollinators)

A collections of booklets that recommends the best plants for attracting pollinators such as bees, butterflies and birds to various eco-geographic regions of the United States, including the “Pacific lowland mixed province forest” (Oregon & Washington). The booklet also describes the pollinators likely to be found living in the regions as well as general information on encouraging pollinator populations. Published by the The Pollinator Partnership┢/North American Pollinator Protection Campaign.

CABI Compendium Invasive Species

Centre for Agriculture and Biosciences International (CABI) provides a detailed coverage of invasive species threatening livelihoods and the environment worldwide and it includes an Invasive Species Discovery Tool.


NatureServe Explorer

An impressive database of information for over 70,000 species of plants and animals and ecosystems of the United States and Canada. NatureServe is a non-profit conservation organization that provides the scientific information and tools needed to help guide effective conservation action. Data includes conservation status, distribution and economic attributes.

Millennium Ecosystem Assessment

A United Nation initiated effort that “assessed the consequences of ecosystem change for human well-being. From 2001 to 2005, the MA involved the work of more than 1,360 experts worldwide. Their findings provide a state-of-the-art scientific appraisal of the condition and trends in the world’s ecosystems and the services they provide, as well as the scientific basis for action to conserve and use them sustainably.”

ECOTOX Database System

The ECOTOXicology database is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX integrates three toxicology effects databases: AQIURE (aquatic life), PHYTOTOX (terrestrial plants), and TERRETOX (terrestrial wildlife). These databases were created by the U.S. EPA, Office of Research and Development, and the National Health and Environmental Effects Research Laboratory.

Center for Agroecology and Sustainable Food Systems

The Center for Agroecology & Sustainable Food Systems is a research, education, and public service program at the University of California, Santa Cruz, dedicated to increasing ecological sustainability and social justice in the food and agriculture system.


A large collection of plant images, mostly woody trees and shrubs, with various browsing methods to find the images. The most useful method is a map of North America divided into bioregions. Each bioregion has an associated list of dominant plants. Created by Steve Baskauf of Vanderbilt University.

Urban Habitats

“Urban Habitats is an open-access electronic journal that focuses on current research on the biology of urban areas. Papers cover a range of related subject areas, including urban botany, conservation biology, wildlife and vegetation management in urban areas, urban ecology, restoration of urban habitats, landscape ecology and urban design, urban soils, bioplanning in metropolitan regions, and the natural history of cities around the world.” Urban Habitats will become Urban Naturalist. The Urban Habitats site will remain available for past journal issues.
