Earthspan is a registered 501(c)(3), not-for-profit organization.
EARTHSPAN’s initial focus was based on population studies of migrating tundra peregrine falcons. Satellite technology plays a large role in tracking the falcons and other migrating species. Close monitoring of the migrants through blood sampling determines what, if any, exposure to biocides such as pesticides or heavy metals are encountered during migration and in the birds’ critical habitats.
Analysis of the satellite-derived animal location data with geographic information systems can relate animal movements and activities to geo-political boundaries, habitats, ecological community structures, land use activities and virtually any geographically discrete database.
Additional technology tools, such as remote sensing – i.e. satellite and aerial imagery – allow scientists to evaluate habitats, vegetation cover, soil moisture and community structures without having to visit the site in person. These technologies can be applied to any species large enough to carry a satellite-received transmitter. The smallest transmitters currently available now weigh less than 16 gm. With them, animals can be tracked anywhere on Earth.
EARTHSPAN principals pioneered the development of satellite biotelemetry technology for wildlife research applications beginning in the 1980s.
Earthspan principals have studied a wide variety of avian species, including Tundra Peregrine Falcons, Ferruginous Hawks, Swainson’s Hawks, Golden and Bald Eagles, Steller’s Sea Eagles, Broad-winged Hawks, White-faced Ibis, and White Pelicans. The group has also tracked a variety of other animals, such as Pronghorn, Oryx, Wild Horses, and Wolves.
