In order to conserve animals, we need to know what habitats they are using throughout their lives. While Powdermill’s more than 50-year-old bird banding program has taught us a lot about how bird populations have changed over time, we know comparatively little about where these birds go after they leave Powdermill. Traditional mark-recapture methods, such as bird-banding, result in less than 1 in 1000 birds being re-detected at another location. However, technological advances now permit radio frequency nano-tags, about the size of a black bean, to be attached to even small-bodied species. These tags emit a coded signal that identifies the individual and can be tracked on the ground or be detected by any automated sensor when an individual animal comes within range. When attached to large antennae placed at least 40 feet high, these sensors can detect wildlife within a ~9-mile radius. We deployed 47 nano-tags on five species this past spring at PNR. With 17 tags redetected (36%), this methods proved to be more than 350 times more effective at tracking the movement of species than traditional mark-recapture methods.

In collaboration with the CMNH Section of Mammals, the GIS Lab has produced a web map documenting the route and highlights of the 1911-1912 Childs Frick Abyssinian Expedition. Childs Frick is the son of renowened Pittsbugh industrialst Henry Clay Frick. Over 500 mammals were collected for the Carnegie Museum during the expedition.

You can now access records from seven DEP oil & gas reports through the GIS Lab’s unconventional wells map viewer. All records from the permits issued, SPUD, PUC, waste, compliance, production, and well formation reports are now available for each well in the map. To access these records, click on a well of interest. In the well pop up, click “Show Related Records” to access a table of records specific to that well.
The CMNH GIS Lab has released a web app highlighting recent forest ecology research initiatives at Powdermill Nature Reserve following a unique research opportunity, a large wind storm in June 2012. The project aims to test the long-term effects of salvage logging and deer exclusion on forest regeneration and wildlife following a major disturbance. The application combines maps, photos, and some background text to acquaint users with the project.
In collaboration with Civic Mapper, the Powdermill GIS Lab has captured fine-scale aerial imagery across various part of Powdermill Nature Reserve using an unmanned aerial vehicle (UAV). Imagery from two locations, the nature center and the avian research center, have been added as an optional layer to the Powdermill Nature Reserve web map. (Note: for best results turn off the Powdermill Nature Reserve boundary layer). The imagery was captured on October 29th and 31st using a Go Pro camera on a DJI Phantom 2 flying at 40 meters. If you would like either of the full mosaic images (with or without georeferencing), please contact the GIS Lab.
The Carnegie Museum of Natural History GIS Lab has produced a new web map viewer that adds additional functionality. Users can now graph unconventional gas production, violations, or data errors either state-wide or over a user-defined area by clicking the “Chart” button. The new “Draw” button allows the user to add graphics and text in order to produce their own maps. Like the previous web map, users can click on any well to view information in permits, drilling, inspections, violations, and other information. Users can still also can click on any producing well to see a graph of gas production since mid-2009 for that specific well. Stay tuned for an additional forthcoming update that will give users the ability to access a table of information on wells by stage, which can be filtered by map extent and exported as a CSV.
