Mapping Western Hemisphere Fauna Bruce E. Young bruce_young@abi.org Association for Biodiversity Information(http://www.abi.org)
Association for Biodiversity Information(ABI) Mission: To develop, manage, and distribute authoritative information critical to the conservation of the world’s biological diversity.
What Information do we Need for Conservation? • What is it? • Where is it? • How is it doing? • What are its requirements? • Where to conserve it? • At a site, what are the threats and how do we address them?
ABI: ~80 staff plus members of the Natural Heritage Network • A “spin-off” of The Nature Conservancy • 77 independent “member” programs • Common methodology • Each program: ecologists, botanists, zoologists, data specialists • Programs in 50 U.S. states, 10 Canadian provinces, and 10 Latin American countries
Organizational Homes for Natural Heritage Programs(US and Canada) • 78% State or provincial agency • 12% University • 5% Non-profit (e.g., Nature Conservancy) • 5% Other (Navajo Nation, National Park, District of Columbia)
What do Natural Heritage Programs Do? Gather, manage, analyze, and distribute information about the biological diversity found within their jurisdictions • Secondary sources & field inventories • Map & manage data • Conduct environmental reviews & assessments • Design, protect, and manage conservation areas
Element Occurrence Element Occurrence • is an area of land and/or water in which a species is, or was present. • has practical conservation value. • tracked for endangered species
Six generations to date of Natural Heritage database software
Bird and Mammal Mapping Project Objectives • Digitize the ranges of all bird and mammal species (~5,600) of the Western Hemisphere • Disseminate the data to the conservation public
Bird and Mammal Mapping Project History • TNC-Wings “Setting Priorities” project (1,300 birds-at-risk) • WWF-US project in Southeastern Brazil (~800 birds) • MOU among CI-CABS, WWF-US, TNC-Wings, ABI
Bird and Mammal Mapping Project Strategy • Gather existing digitized maps • Digitize remaining maps Quality Standards • Minimum 1 degree lat/long grid • Comparable base map • Up-to-date source
Bird and Mammal Mapping Project Sources for Digitized Maps • TNC-Wings • WWF-US • Gerardo Ceballos (UNAM) • Patricia Escalante (UNAM) • Stuart Pimm (U. Tennessee) • Ross Keister (USFS) • Don McNicol (CWS)
Bird and Mammal Mapping Project Data Sources Birds • North America:Birds of North America • Mexico, northern Central America: Howell & Webb • Southern Central America: James Zook • South America: Robert Ridgely • Caribbean: Raffaele et al.

Bird and Mammal Mapping Project Challenges • Variable precision of contributed maps • Variety of base maps used • Schedules of contributors • Taxonomic instability • Protecting unpublished information • Reflecting movement status • Funding for updates
