RESULTS
Regional LSI
LSI values for the North Texas study area and rural landscape appear to be most
promising with 15.25% and 20.54% of each respective area over 70% suitable. The
study area in particular has potential ecological areas in the northern, western, and
northwestern sections exceeding optimal values. Both the central and southeastern
sections are embedded in areas of low LSI ratings and amidst the metropolitan areas. The
majority of the land falls between 0.20 and 0.80 in the LSI. Meanwhile, the rural mask at
the center of locating new FCA areas and wildlife corridors possesses sections of high
LSI values in the northern, western, and northwestern areas while the southern exterior
and southeast portions show high levels of human impact. The dominant land LSI values
for the rural landscape fell between 0.33-0.80 which suggests a high potential for low to
mid value land areas to be future links or hubs in a larger conservation network. With
over 20% of the rural area surpassing 0.70 LSI approximately 800,000 acres of land are
potentially suitable for wildlife inhabitation and new FCA locations. An optimal location
for reserve selection can follow areas of contiguous high-rating areas as suggested in the
distribution of LSI values.
The major ecoregions of this study showed marked differences, particularly
between the two extremes of the Western Cross Timbers and Blackland Prairies. While
the former appears to have the greatest potential for conservation efforts with over 30%
suitability the latter is the most impacted and fragmented landscape with only 4.1%
deemed suitable. The highest concentration of suitable land within the Western Cross75
