Cavity-Nesting Wildlife in Southern Forests Intensive management of forests for timber production reduces essential habi- tat for wildlife that use tree cavities because there are fewer old and deca- dent trees in these managed stands. Research by the Southeastern and Southern Experiment Stations is defin- ing habitat relationships and developing techniques for accommodating cavity- nesting wildlife in managed stands. A major goal for recovery of the endan- gered red-cockaded woodpecker is to provide nesting habitat in appropriate amounts and spatial arrangements to facilitate population increase. Research has shown that red-cockaded woodpecker colony sites are located in relatively open, old-growth forests dominated by pine with a low density of hardwood trees. This is particularly significant in view of the finding that there has been a decline of 13 percent in southern old-growth pine habitats over the past 25 years, and the trend is expected to continue. Nevertheless, definition of how new colonies are formed has provided the first guidelines for the location and distribution of nesting habitat to stabilize populations and facilitate population expansion. Other research has focused on methods for providing suitable habitat conditions for a variety of cavity-nesting birds. For example, development of a technique for inoculating selected individual pines with a wood-decay fungus could be used to make relatively young trees suitable for cavity excavation. Similarly, experiments with southern red oak have resulted in techniques for treating trees to permit growth of heartwood and sapwood- decaying fungi, conditions necessary for woodpecker nest-cavity excavation.
