Homestead National Monument Of America, Acoustic Monitoring Report, 2017, Emma Brown
Homestead National Monument Of America, Acoustic Monitoring Report, 2017, Emma Brown
United States National Park Service: Publications
Executive Summary
This report presents acoustical data gathered by Student Conservation Association interns and the Natural Resource Specialist at Homestead National Monument of America in 2017. Data were collected at one site to provide park managers with information about the acoustical environment, sources of noise, and the existing ambient sound levels within the monument. This deployment also captured acoustic conditions during the total solar eclipse on 8/21/2017. (Results of the eclipse monitoring effort are provided in Appendix B.)
In this deployment, sound pressure level (SPL) was measured continuously every second by a calibrated sound level meter. Other equipment included an …

Homestead National Monument Of America, Acoustic Monitoring, 2011-2012
United States National Park Service: Publications
Executive Summary
This report presents acoustical data gathered by Student Conservation Association interns and the Natural Resource Specialist at Homestead National Monument of America in 2011 and 2012. Data were collected at four sites to provide park managers with information on the acoustical environment, sources of noise, and the existing ambient sound levels within the monument. The data will also inform the park managers with information regarding the potential impact of traffic on Highway 4.
Monitoring occurred at each site during two different seasons (except HOME002) in order to document seasonal variations. In each deployment, sound pressure level (SPL) was …
Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht
Homestead National Monument Of America, Bat Acoustic Monitoring, September 2016, Daniel S. Licht
United States National Park Service: Publications
Abstract
Homestead National Monument of America is a 211-acre park located in an agrarian landscape in southeastern Nebraska. From September 16 to October 1, 2016, park staff deployed acoustic monitors at three sites in the park for purposes of monitoring night-time bat activity. The three sites averaged 179, 48, and 33 bat detections per night. Night-time bat activity was generally highest in the 1-2 hours following sunset.
Based on the acoustic surveys the big brown (Eptesicus fuscus), eastern red (Lasiurus borealis), northern long-eared (Myotis septentrionalis) and evening bats (Nycticeius humeralis) were present at the …
Climate Matching As A Tool For Predicting Potential North American Spread Of Brown Treesnakes, Gordon H. Rodda, Robert N. Reed, Catherine S. Jarnevich
Climate Matching As A Tool For Predicting Potential North American Spread Of Brown Treesnakes, Gordon H. Rodda, Robert N. Reed, Catherine S. Jarnevich
Managing Vertebrate Invasive Species
Climate matching identifies extralimital destinations that could be colonized by a potential invasive species on the basis of similarity to climates found in the species’ native range. Climate is a proxy for the factors that determine whether a population will reproduce enough to offset mortality. Previous climate matching models (e.g., Genetic Algorithm for Rule-set Prediction [GARP]) for brown treesnakes (Boiga irregularis) were unsatisfactory, perhaps because the models failed to allow different combinations of climate attributes to influence a species’ range limits in different parts of the range. Therefore, we explored the climate space described by bivariate parameters of …

Invasive Species: A National Perspective And The Need For A Coordinated Response, Lori Williams
Managing Vertebrate Invasive Species
The multiple economic, environmental, and animal and human health impacts of invasive species pose complex challenges in policy formation and governmental coordination. The National Invasive Species Council (NISC) was established by an Executive Order in 1999 to provide coordination, planning and facilitate cooperation among the diverse federal agencies and to take a more comprehensive approach to invasive species. NISC, assisted by the nonfederal Invasive Species Advisory Committee (ISAC) has developed several tools and enhanced capacities to address invasive species. Additionally, NISC has helped place greater emphasis on essential prevention, early detection and rapid response, research, public outreach, and international cooperation …
