The U.S. Fish and Wildlife Service (USFWS) is the premier federal agency charged with protecting and enhancing America's treasured fish, wildlife, plants, and their habitats. USFWS works for the perpetuation of diverse and abundant wildlife because biodiversity is essential to maintaining the health of our environment, our families, and our economy.

Both products continue to enjoy high demand and funding for development of new features.

Work on the IPaC team directly correlates with the success of natural resources conservation, and we see the product of our time, energy, and creativity making a difference.
