- Effects of Clearing Linear Features through Forest Patches in WV and VAMoore, Sierra; Klopfer, Scott D. (Virginia Tech, 2021-04-30)Recent pipeline construction through predominantly forested mountain areas presents many concerns for environmentalists. Impacts from construction are often measured in total area of forest removal, but this may not capture the extent of change to the landscape. Other effects, such as increased fragmentation and edge go unmeasured. We examined changes to the forest landscape resulting from the Mountain Valley Pipeline; a recently constructed corridor that runs through West Virginia and Virginia. We identified affected forest patches using the 2016 National Land Cover Dataset and analyzed both pre- and post-construction patch characteristics. The total area of forest removed was 1,182.57 ha, (0.03%). The total core forest decreased by 5,781.33 ha (2.7%). The number of forest patches increased from 242 to 667, with an average of 2.9 new patches per original patch. The edge density increased 5.4% between pre and post pipeline (0.0059 m/ha to 0.0062 m/ha). Area/Perimeter ratio increased between pre and post construction (0.049 to 0.2524). Our results demonstrate that area, alone, is insufficient to determine the total impacts of linear construction on forest in the study area, particularly since the loss of core forest and increasing edge have well-documented impacts to ecological processes.

- Insolation, Precipitation, and Moisture Maps for a Virginia Geographic Information SystemKlopfer, Scott D. (Virginia Tech, 1997-07-25)Climate information is valuable in understanding the ecology of systems affecting wildlife. This information is often unavailable at the landscape scale. This study evaluated the applicability of several climate factor estimates at the landscape-scale, and illustrated the usefulness of estimated climate factors in ecological investigations. Climate variables estimated for each month of the year were solar radiation, temperature, precipitation, and potential evapotranspiration. Map layers for combined temperature and precipitation, and a moisture index were also created. Accuracy of the estimates for temperature and precipitation for each 300 m x 300 m pixel were quantitatively assessed. The methods used estimated mean monthly temperature within 1 degree C. Precipitation estimates were within 9 mm of actual recorded value. The estimates for monthly solar radiation were qualitatively assessed, and provided a reasonable relative index to actual solar radiation. Estimates of potential evapotranspiration were determined to be reasonably accurate. Landscape-scale estimated climate factors were used in 2 case studies. The first used logistic regression to examine the importance of climate factors to the observed distribution of 21 select forest cover-types in Virginia.The second compared the observed climate characteristics for the distributions of 3 species of terrestrial salamanders in Virginia. Winter temperature was the most important climate variable in determining forest cover-type distribution. Several differences in the climate characteristics of the 3 salamander distributions were observed and discussed. The conclusions of this study were that landscape-scale climate factors can be accurately estimated, and the estimates may be helpful in ecological investigations.

- Natural Resource Condition Assessment: Castillo de San Marcos and Fort Matanzas National Monuments, FloridaDorr, Jessica; Palmer, David; Schneider, Rebecca; Galbraith, John M.; Killar, Myles; Klopfer, Scott D.; Marr, Linsey C.; Wolf, Eric (National Park Service, 2012-04)The goal of this assessment is to provide an overview of natural resource condition status to allow Castillo de San Marcos and Fort Matanzas National Monuments (NMs) to effectively manage National Park Service (NPS) trust resources through Resource Stewardship Strategies (RSS) and General Management Plans. An ancillary benefit is that it will aid the park in meeting government reporting requirements, such as the land health goals under the Government Performance Results Act (GPRA). This assessment is primarily based on existing data and information from the NPS Inventory & Monitoring Program, and from other Federal and State natural resource agencies.
