Camera Trap Survey Suggests Forestry And Prescribed Burns Attract Wildlife, But May Not Enhance Diversity, Melissa S. Vilgats, Ryan Ott, Stephanie S. Coster
Virginia Journal of Science
This study explored whether habitat management techniques such as forest thinning and burning promoted biodiversity. Fifteen camera trap stations were established at Fort A.P. Hill in Bowling Green, VA across forest stands with low, medium, and high basal area. Camera traps were deployed for a total of 532 trap nights, and trap success and species diversity were calculated using Shannon’s index. At each site, the distance to trafficable roadways and water sources, vegetation composition, and the percent groundcover, canopy cover, and understory were measured. The cameras captured nine species and recorded a total of 398 trap events. Linear regression was …

Remote Detection Of Disturbance From Motorized Vehicle Use In Appalachian Wetlands, Walter Smith
Virginia Journal of Science
Wetland disturbance from motorized vehicle use is a growing concern across the Appalachian coalfields of southwestern Virginia and portions of adjacent states, particularly as both extractive industries and outdoor recreation development expand in regional communities. However, few attempts have been made in this region or elsewhere to adapt approaches that can assist researchers and land managers in remotely identifying and monitoring wetland habitats disturbed by motorized vehicle use. A comparative analysis of wetlands impacted and unimpacted by off-road vehicle activity at a public recreation area in Tazewell County, Virginia was conducted to determine if and how a common, satellite-derived index …

Multi-Scale Environmental Conditions Associated With Shade-Tolerant Conifer Regeneration In Forest Park, Portland, Oregon,

Multi-Scale Environmental Conditions Associated With Shade-Tolerant Conifer Regeneration In Forest Park, Portland, Oregon, Matthew Cook
Dissertations and Theses
Forest Park is a 5,100-acre urban forest located in Portland, Oregon, that has been impacted by various anthropogenic stressors including logging, fragmentation, invasive species, air pollution and recreation use due to its proximity to the urban environment. This legacy of land use coupled with natural disturbances has resulted in changes to forest structure, composition, and function--threatening the long-term sustainability of the park. Past research in Forest Park has identified a lack of regenerating shade-tolerant conifers, particularly western hemlock and western red cedar species, in the section of the park closest to the city. Typically, western hemlock and western red cedar …

Interspersed Denuded Zone (Idz): How Patchy Leaf Litter Dynamics In A Buckthorn-Invaded Urban Woodland Can Affect Microarthropod Species Richness, Angela Stenberg
DePaul Discoveries
Biodiversity loss may serve as a key diagnostic of the Anthropocene. An important driver of this loss is by means of invasive species. In this study of a forest preserve in Chicago, Illinois we examined Interspersed Denuded Zones (IDZs for short), which are areas of patchy leaf litter in invaded forests caused in this case by the rapid decomposition of litter from buckthorn (Rhamnus cathartica). We characterized the leaf litter mass in IDZs and enumerated litter-inhabiting microarthropod populations. We found that plots of high buckthorn density are associated with IDZs: there was significantly less leaf litter mass in …

Household Perceptions And Patterns Of Crop Loss By Wild Pigs In North India, Bivash Pandav, Lakshminarayanan Natarajan, Ankit Kumar, Ajay A. Desai, Banteibor Lyngkhoi
Human–Wildlife Interactions
Loss to cultivated crops by wild pigs (Sus scrofa) is widespread and can jeopardize low-income farmers. In India, although there is lot of political interest in the problem, efforts to understand the patterns, correlates, and underlying reasons for wild pig conflict continue to be minimal. We quantified loss of wheat (Triticum aestivum) to wild pigs and assessed the spatial patterns of damage in a forest settlement of Van Gujjar (Haridwar, India), which is a dairy-based pastoralist community. We chose a 4-km2 cultivated area comprising 400 farmlands (each measuring 0.8 ha and belonging to a family) and …

Opportunities And Challenges In The Collection And Use Of Socio-Spatial Data In National Forest Planning,

Opportunities And Challenges In The Collection And Use Of Socio-Spatial Data In National Forest Planning, Diane Trechsel Besser
Dissertations and Theses
Understanding human-environment connections to places is an important component of land-use management. Tools for collecting geographically referenced public values-based data (defined as socio-spatial data) for use in natural resource planning have been reported in academic journals for decades. The utility of socio-spatial data is in making public values tangible and potentially actionable in land-use analyses and decision processes. However, there is a lack of comprehensive documentation on the ways in which socio-spatial data is perceived, collected, interpreted and applied at a practical level. A better understanding of these factors allows planners to mitigate barriers and leverage opportunities to more …
Soil Disturbance In Sierra Nevada Montane Meadow Following Lodgepole Pine Removal,

Soil Disturbance In Sierra Nevada Montane Meadow Following Lodgepole Pine Removal, Nicholas Cary
Master of Science in Environmental Sciences and Management Projects
Climate change and other anthropogenic stressors are driving conifer encroachment into meadow habitat. Encroachment, if ignored, can revert meadows back into dense forested habitat, negating meadow’s ecologic services (Durak et al. 2014). This research attempts to measure soil and stream habitat disturbances in Rock Creek meadow, located with Collins Pine Company land in Plumas County, California after clear-cut removal of encroaching lodgepole pine with mechanical machinery. Soil bulk density, ground cover transect data, and stream habitat conditions were monitored before (July 2019) and after (June 2021) restoration to measure changes in soil compaction, stream temperature, and surface disturbance (rutting/ tracks). …
Long-Term Hydrological Impacts Of Historical Logging On Recent Hydro-Geomorphic Conditions, Big Barren Creek Watershed, Mark Twain National Forest,

Long-Term Hydrological Impacts Of Historical Logging On Recent Hydro-Geomorphic Conditions, Big Barren Creek Watershed, Mark Twain National Forest, Shoukat Ahmed
Graduate Theses/Dissertations
Despite their important role of headwater watersheds as a buffer for upland soil and vegetation disturbances, there has been little research about the effects of historical logging practices on present-day watershed hydrology and channel form. Middle Big Barren Creek (MBBC) watershed (48 km2 ) drains Mark Twain National Forest in the Ozark Highlands and was heavily logged from 1880 to 1920, reducing native shortleaf pine forest by 90%. Additionally, the frequency of intense rainfall events has increased in the region over the past 30 years. In this study, field surveys and hydrologic/hydraulic modeling were used to evaluate the historical timber …
The Effects Of Prescribed Burning On Soil Water Infiltration Rates And Other Select Soil Physical And Chemical Properties In East Texas,

The Effects Of Prescribed Burning On Soil Water Infiltration Rates And Other Select Soil Physical And Chemical Properties In East Texas, Cassady Pennington Dunson, Brian P. Oswald, Kenneth Farrish, Tyson Hart
Electronic Theses and Dissertations
This study focused on whether prescribed burning affects soil physical and chemical properties, especially water infiltration, in Western Gulf Coast forests. Soil water infiltration rates were measured 1) pre-burn (before the fire), 2) post-burn (one month after the fire), and 3) at vegetation green-up (three months after the fire). Soil samples were also collected to determine the effects of prescribed burning on soil pH, bulk density, particle density, pore space, soil strength, O-horizon weight and depth (organic matter), water stable aggregates, and soil fertility. This project was conducted on two different burn intervals. The National Forests and Grasslands of Texas …
