| | Title | Impacts of selective tree harvesting on the Delmarva fox squirrel |
| | Project Description | The Delmarva fox squirrel (Sciurus niger cinereus) is an endangered species found only in remnant |
| | patches of its former range. Fragmentation of its preferred habitat and potential changes in |
| | silvicultural practices on the Delmarva peninsula may pose serious threats to its stability. Its |
| | decline is being mirrored by most, if not all, of the eastern subspecies of fox squirrels. The |
| | demographics of the Delmarva fox squirrel in relation to forest age and stand conditions are |
| | unknown and management practices to produce and maintain suitable forest habitat are untested. |
| | The immediate objectives of this study are 1) to investigate the impact of a clearcut with reserves |
| | on the density, age- and sex-specific survivorship and dispersal rates, and habitat correlates for |
| | Delmarva fox squirrels, 2) to refine and standardize data collection and survey techniques for |
| | squirrels, and 3) to compare two separate methods of estimating vegetative composition, one of |
| | which is recommended in the Recovery Plan and used to develop a habitat suitability index (HSI). |
