We then calculated the minimum-sized forest patch required to achieve the same probability
of supporting tanagers as a suitable, unfragmented forest. Patches greater than or equal to this minimum
area are defined as having High Suitability for tanagers in the minimum-area tables. We defined
Moderate Suitability patches as those that have a 25% lower probability of supporting tanagers, relative
to unfragmented forest, and determined the minimum area required to achieve that lowered
probability. Similarly, we calculated the minimum area of Low Suitability patches, which are 50% less likely to
support tanagers relative to unfragmented forest. Because minimum areas are dependent on the amount of forest
in the surrounding 2,500-acre (1,000-ha) landscape, a range of minimum areas is presented for each level
of suitability. Note that a reduction in habitat suitability is defined here only in terms of the effect of
forest fragmentation and otherwise assumes that forest type and structure are favorable for breeding tanagers.
