This population appears to be near nutritional carrying capacity based on the moderately high APC value, the levels of other parasites and pathologic conditions, and the general physical parameters of the animals. Currently, the herd does not appear to have any significant density related health problems, and we did not encounter any overtly diseased deer. The herd has moderate immunity to epizootic hemorrhagic disease viruses, but prediction of future activity by the hemorrhagic viruses is not possible. Our data indicate that the herd can be maintained near its present density without undue risk of declines in herd health provided that habitat quality remains stable. Any significant increase in density can be expected to be accompanied by problems with a syndrome of parasitism and malnutrition. The physical parameters for this population are generally lower than those for the Yazoo National Wildlife Refuge animals, and my explanation for this is the higher soil fertility and more extensive availability of agricultural crops at Yazoo National Wildlife Refuge.

In the September 2, 2003, Environmental Assessment, the U.S. Fish and Wildlife Service Service considered the environmental effects of acquiring 4,004 acres 1 in Jefferson and Whitefield, New Hampshire, and adding them to the Pondicherry Division, a Special Focus Area for resource protection within the Silvio O. Conte National Fish and Wildlife Refuge NFWR. The Environmental Assessment also contains preacquisition Compatibility Determinations to allow the continuation of wildlifedependent and compatible public uses, such as hunting, fishing, wildlife observation and photography, and environmental education and interpretation. A range of issues and concerns were identified during the public involvement process. These were considered in conjunction with refuge purposes, the purpose of and need for the proposal, and the refuge goals and objectives in developing alternatives and evaluating their impacts. Copies of the.Environmental Assessment documents were sent to the eight landowners within the proposed acquisition area, as well as those landowners adjacent to the project. Copies were also sent to local and State officials, Congressional representatives, and all individuals who requested copies of the documents.

Nesting females were monitored on the beach between Sandbridge and the North Carolina state line by personnel from the Back Bay National Wildlife Refuge BBNWR. On 11 July 1993 an emerging female was allowed to complete nesting, was constrained to prevent escape, then weighed and measured Photograph 1. A satellite transmitter Telonics model ST6 was affixed to the carapace of the turtle with plastic resin, a noninvasive procedure Photographs 2 and 3. We have utilized this methodsuccessfully on over 15 turtles Keinath, 1993. The turtle was then released at BBNWR that morning Photograph 4, and movements and behavior were monitored until the transmitter failed on 28 July 1993. Travel routes were plotted and distances traveled and movement speeds were calculated. Diving behavior was described from data collected by 5 sensors on board the transmitters.

Summary
Description
Refuge hunting for the 1998 season included whitetailed deer and feral hogs only. The State of Virginias Department of Game Inland Fisheries VDGIF maintains a policy of permitting deer hunting on an established deer herd. The presence of the deer herd requires hunting of that herd, especially if the habitats supporting that herd are lowquality poor soils and limited forage. The Refuge supports this State policy. The current hunting areas at Back Bay National Wildlife Refuge meet this policy standard. An established deer herd has been existing within very limited, substandard barrier island habitats. This herd has been open to hunting since 1986. The feral hog is also open to hunting. It is not a naturally occurring wildlife species here. Instead, it is often considered a pest that consumes valuable wildlife food, disrupts wildlife habitat and threatens the dike system slopes with erosion damage where they root.
Species-specific patterns of fine root demography and hydraulic lift among trees of the fall-line sandhills

Summary
Description
Below ground processes, such as fine root demography and soil water redistribution, can alter carbon, nutrient and water cycles in terrestrial ecosystems. Although these processes are known to differ significantly across broad spatial scales and plant functional types, little is known about the differences among species in narrow geographical scales. Studies were conducted in a group of five tree species that grow in the sandhills of the fallline region of southeastern United States. Four Quercus species Q. laevis, Q. incana, Q. margaretta and Q. marilandica and the longleaf pine Pinus palustris cooccur in areas of intermediate fertility, but have different distribution along soil resource gradients. Species differences in fine root demography and hydraulic lift were studied by growing roots of adult trees in field rhizotrons and recording fine root production, death and lifespan and the water potential of the soil near the roots. The effect of variation in resource availability water and nutrients on fine root demography was also studied in greenhouse studies using seedlings. The species able to colonize xeric habitats Q. laevis and Q. incana exhibited fine roots with greater longevity but lower rates of production, death and percent mortality than species dominant in mesic habitats Q. margaretta and Q. marilandica. The generalist species P. palustris exhibited intermediate fine root demography. Fine root death increased under high resources and under localized drought, especially in mesic species. Fine root production in mesic species was greater at high resource availability and after reenrichment of dry surface soil. Only xeric Quercus species and the generalist P. palustris exhibited hydraulic lift ability. Consistent with optimality theory, these results suggest that greater fine root lifespan and hydraulic lift ability in xeric and generalist species may favor root persistence in dry soils, potentially reducing rates of resource loss. In contrast, greater fine root growth in mesic and generalist species may favor competition for resources. Results also indicate that species differences can be substantial even across congeners and narrow spatial scales. Hence, speciesspecific belowground processes deserve further investigation in order to understand how carbon andnutrient cycling respond to environmental change and shifts in species composition.
