The 50 percent recommendation is based on capturing 75 percent of the threshold values surveyed; 20 percent is based on capturing 50 percent of threshold values surveyed. The latter recommendation is provided because land use planners are often working in highly developed regions where protecting 50 percent or more of the landscape is impractical. THRESHOLDS | 25 RECOMMENDATIONS FOR FUTURE RESEARCH AND ACTION THE ROLE OF THE SCIENTIFIC COMMUNITY Mammals made up 24 percent of the research on proportion of suitable habitat; 21 percent on patch area; 11 percent of research on buffers; and 9 percent on edge effects.
