The Atlantic CDC maintains comprehensive lists of plant and animal species, with a rarity rank and legal status for each. These lists aid the development of sub-national rarity ranks (S-ranks). To date, the Atlantic CDC has compiled S-ranks for most vascular plant and vertebrate animal species and for some non-vascular plant and invertebrate species. The Atlantic CDC has over 40,000 records of extremely rare to uncommon species in the Atlantic region and also maintains biological and other types of data (ex: information sources and professional contacts) in a variety of linked databases.

BC Species and Ecosystems Explorer is a source for authoritative conservation information on approximately 6000 plants and animals, and almost 600 ecological communities (ecosystems) in British Columbia. It provides conservation status, taxonomic, and distribution information for vertebrate animals, vascular plants, mosses, butterflies, dragonflies, damselflies, tiger beetles, non-marine moluscs and many ecological communities. BC Species and Ecosystems Explorer represents a "snapshot" of dynamic data that are continually being refined by the BC Conservation Data Centre (CDC).

As a member of the Global Biodiversity Information Facility (GBIF), CBIF is exploring new ways to improve the organization, exchange, correlation, and availability of primary data on biological species of interest to Canadians. CBIF has developed the following tools to help users find the information they need:

• Integrated Taxonomic Information System
• Species Access Canada
• Online Mapping
• SpeciesBank

The Canadian Bird Trends Web site is a retrieval system that provides information on Canadian bird species, including population trends and taxonomy, with links to range maps and life history information, and national conservation designations.

Population trends are derived from Breeding Bird Survey in Canada (BBS) data and are updated on an annual basis. No trends are presented for species, provinces, territories or Bird Conservation Regions for which BBS data are insufficient for statistical analysis.

The results at this web site use data from Canadian routes only. Combined results for the United States and Canada are available on the USGS North American Breeding Bird Survey Web site.

The Canadian Poisonous Plants Information System presents data on plants that cause poisoning in livestock, pets, and humans. The plants include native, introduced, and cultivated outdoor plants as well as indoor plants that are found in Canada. Some food and herbal plants that may cause potential poisoning problems are also included.
