Northern Prairie Wildlife Research Center
At least 100 available GISs of various types for a wide array of computers are available from many government agencies, universities, and commercial vendors (Parker 1991). It is hoped that wildlife managers desiring to use GIS technologies will not get bogged down in the bits, bytes, and ". . . primordial ooze of system development or primitive promotions" (Giles 1991:5), but will become excited about the capabilities provided by GISs to gain ".. . explanatory, descriptive, and predictive control ..."(Giles 1991:5) of ecosystems.

Fig. 18. -- (upper right) Habitat classes derived from Landsat TM data and used in simulating waterfowl production. Fig. 19. -- Three habitat changes simulated by using editing functions of a GIS. Fig. 19A. -- (upper center) depicts the creation of a large impoundment. Fig. 19B. -- (lower center) depicts the simulated conversion of 50% of the existing cropland to CRP planted cover. Fig. 19C. -- (bottom) shows the location of a simulated predator barrier fence surrounding tall, dense, nesting cover.|
