may be insecure . Allegedly there has been some fragmentation from residential development . The extent of this fragmentation needs to be assessed, and the current biological value of the site determined . Conservation strategy would then be based on current integrity . 8 . River corridors : Eno River, N and S forks of the Little River (See III .B above) : Conservation efforts should focus on protection of the Upper Eno River basin, and along both the North and South Forks of the Little River, for water quality protection, rare species protection, and for the maintenance of wildlife corridors . 9 . Forest southwest of Cedar Grove : a large tract of forest was identified southwest of Cedar Grove by LWW4 and -II . This forest was identified from aerial photographs solely based on its size . It should be surveyed for biological importance . Its current status is not known . Conservation effort would then reflect results of such on- site survey . 10 . Pickard' s Mountain : While Pickard' s Mountain is now relatively secure , in environmentally responsible private hands, it remains an area of biological importance , primarily by virtue of its size and its unfragmented status . The County should be kept apprised of the status of this land and perhaps work with the landowner to encourage putting the tract, or parts of it, under conservation easement. Also , the County should work to encourage habitat connectivity between Pickard' s Mountain and Bald Mountain, through easements and/or acquisition . B . A Dynamic Biological Inventory Biological systems are dynamic entities , changing over time and shifting spatially on the landscape . What we see today is merely one point in the history of the landscape , and not a static reflection of the " Balance of Nature " . In addition, new sites are identified through increased exploration of the landscape, acquisition of new knowledge, and temporal changes in biotic communities . County protection efforts need to take this spatial and temporal dynamism into account . To keep its biological information current, Orange County needs to develop a dynamic biological inventory that builds the 1988 inventory by Sather and Hall and the two recent Landscape with Wildlife reports from TLC . This dynamic inventory will respond to changes that occur as new sites are described and as documented sites are lost through land use changes . Updating the inventory could be the joint responsibility of an Inventory Review Committee comprised of biologists and conservation workers , and the Land Resources Conservation Manager . The updated inventory could both be made available as a resource to entities working to protect natural areas within the county, and could serve as the repository for biological data gathered by these groups . NC Natural Heritage Program has indicated that funding may be available for such an update (Rich Shaw, pers . comm . ) C . Improved Inventory of Resources in Northern Orange County While the greater presence of agricultural activity, as well as the nature of the soils , makes it less likely that unusual species will be found in northern Orange County , there remains a need for greater biological exploration in the northern County .
