Eventually, 83 individuals served as Regional Coordinators (see the list under the Credits tab).Breeding bird atlases employ a set of codes to record the behaviors associated with nesting activity, ranging from the simplest detection by sight or sound, through confirmation of active nests and fledged young.

Local coordination was provided by volunteer Regional Coordinators, who provided the foundation for organizing fieldwork. Geological Survey 7.5-minute topographic map, of which 4,937 were identified for survey coverage. Following the recommendations of the North American Ornithological Atlas Committee, the basic survey unit was the “block,” defined as one-sixth of a standard U.S. Bob Mulvihill and Mike Lanzone were project co-coordinators. In fact, up to three maps per species show in fine detail the current distribution of all breeding birds based on the second Atlas, changes in distribution since the first Atlas, and, for more than one hundred species, their density across Pennsylvania.The field project was based at Powdermill Nature Reserve, environmental research center of the Carnegie Museum of Natural History, in Rector, Pennsylvania. The core results of the project are the distribution maps. The data amassed reveal the distribution of each species and show changes in distribution since the publication of the first Atlas.

More than two thousand dedicated birdwatchers completed surveys of birds across the state from 2004 to 2009. Twenty years after the first Atlas of Breeding Birds in Pennsylvania was published, the Second Atlas of Breeding Birds in Pennsylvania brings our knowledge of the state’s bird populations up to date, documenting current distribution and changes in status for nearly two hundred breeding bird species.

Identifying areas that are at high risk of forest fires based on historical locations of forest fires.The result layer will show areas with high and low accessibility to hospitals, and this information can be used to decide where new hospitals should be built. Calculating densities of hospitals within a county.Creating crime density maps to help police departments properly allocate resources to high crime areas.Other use cases of this tool include the following: This result can be used to identify areas that are hospitable to grazing animals. For example, if the lines represent rivers, the result layer will represent the total length of rivers that are within the search radius. The units of the calculated density values are the length of line per unit area. For example, if the input points represent locations of lightning strikes, the result layer can be interpreted as a risk surface for future lightning strikes.įor line input, the line density surface represents the total amount of line that is near each location. In many cases, the result layer can be interpreted as a risk surface for future events. A higher density value in a new location means that there are more points near that location. For point input, each point should represent the location of some event or incident, and the result layer represents a count of the incident per unit area.
