The Western Hemisphere
The Conservation Agency has
supported projects in the Western Hemisphere from Newfoundland to Brazil. In the Canadian
Maritimes and New England our subjects have been whales, marine and salt-marsh turtles,
vernal pond wildlife, salamanders and acid rain, wetlands protection, and coastal island
biogeography.
On the Outer Banks of North Carolina, islands that
function as sand conveyer-belts, we have chronicled ecology and evolution and have
observed adaptations of burrowing animals, migratory birds, and freshwater- dependent
amphibians and reptiles.
In California we have
concentrated on the chaparral and old-growth forests of Mount Tamalpias, where north and
south meet and merge. We have challenged stereotypical views of controlled burning and
other management techniques which are not appropriate in all cases.
Our staff has dedicated two
decades of research to the critically endangered wildlife of the Florida Keys. From mice
to miniature deer, these animals have inspired a battle to save critical habitat for
unique species found nowhere else on earth. In 1991, due largely to efforts by The
Conservation Agency and the Sierra Club Legal Defence Fund, the silver rice rat, a new
species of small muskrat-like mammal discovered by staff biologist Dr. Numi Mitchell, was
placed on the Federal List of Endangered Species. The rice rat and thousands of hectares
of its Florida Keys habitat are now protected from development jeopardizing their
survival. The Conservation Agency's studies concerning resource use and threats to this,
and other endangered species, have been made available for use by the U.S. Fish and
Wildlife Service for incorporation in their recovery plans.
West Indies projects are
among our most varied: we are bringing back populations of lost birds such as flamingos,
doves, ducks, and woodpeckers; restoring dry forest habitats; and creating management and
recovery strategies for populations of giant iguanas, dwarf owls, and fishing bats. We are
rapidly discovering new species of iguanid lizards, skinks, ground geckos, and many
invertebrates, and are managing whole island ecosystems as wildlife sanctuaries. We have
submitted a half-dozen management plans for disappearing West Indian wildlife and have
made these available to local governments at no cost.
In Brazil we completed a
comparative study of the Outer Banks, the world's largest sand barrier. Here we
investigated worm lizards, microlepidoptera (insects), iguanid lizards of the maritime
forests, and studied contrasts and comparisons with the barrier islands of North Carolina
where our investigations span more than 20 years.
