Figure 1.
Current dominant land use around each National Wildlife Refuge in the contiguous 48 states.
Figure 2.
Box plots showing the variability in each land use across the scales of analysis for different land-use classes (row 1), and the maximum difference among scales in proportion of land in each use around the National Wildlife Refuges (row 2).
Plots in row 2 compare conditions in 2001 (in white) with those in 2051 for each scenario (BAU = business-as-usual, PNH = preserve-natural-habitats, RUG = restricted-urban-growth).
Table 1.
Percent of National Wildlife Refuges dominated by different land-use categories, at three different scales (buffer distances) and the proportion of each use category on all private lands nationwide.
Table 2.
Land area (million ha) and percent areain different land uses within 25 km of the National Wildlife Refuges in 2001 and 2051 under each scenario.
Figure 3.
Initial land use and change in forest/range land use within 25 km of refuges under the different scenarios.
Absolute change = change in area (ha), buffer change = percent of buffer that changes use, and rate of change = percent growth.
Figure 4.
Initial land use and change in crop/pasture land use under the different scenarios.
Figure 5.
Initial land use and change in urban land use under the different scenarios.
Figure 6.
Regional predictions for the percentage of area within 25 km of refuges that will change under the different scenarios.
Inset shows FWS administrative regions.
Figure 7.
Change in area in different land uses and rates of change among the different scenarios for the FWS administrative regions.
FR is forest/range, CP is crop/pasture, and U is urban land use.
