Dataset: Grey-headed Flying-fox Camps


Description

Note: The NSW database of flying-fox camps is no longer maintained.

An interactive flying-fox web viewer hosted by the Australian Government Department of the Environment and Energy has been developed to visually present data from the National Flying-fox Monitoring Programme.

The viewer allows users to explore flying-fox camps and the numbers of each species counted over time. This information spans the data gathered from November 2012 to present.

See below for superseded data description; this dataset is no longer updated as of 25/10/16.

This dataset contains information on grey-headed and black flying-fox camp locations for coastal New South Wales and notes whether little red flying-foxes are also present. The data represents locations that have been used by grey-headed flying-foxes or black flying-foxes since 1990. Flying-foxes change their use of these areas from season to season and year to year. Few sites will be occupied continuously, and some may only be used every few years. The use of sites by flying-foxes will generally reflect the availability of native food (pollen and fruits of native trees). It is intended to be indicative of the location of such camps and is not exact.

The majority of camp locations were documented during range-wide surveys of grey-headed flying-foxes conducted from 1998 to 2004. The dataset provides presence/absence data only, ie. it does not include abundance estimates.

The flying-fox camp database is an Excel spreadsheet which contains AMG Zone 56 Eastings and Northings. The spreadsheet has been converted to a point locality GIS layer (ESRI shapefile) via these coordinates but then reprojected to GDA GCS. The AMG coordinates in the table have also been converted to MGA coordinates.

An accompanying polygon shapefile is also provided for camp boundaries. Camp boundaries are only present if the coverage of the camp is known. There was no set cut off size however all boundaries would be >10x10m. Camp dimensions and boundaries vary through time with changing population size and movement of animals around the site. The boundaries provided are the greatest extent documented and are not static.

In 2006/7 DEC engaged a contractor to update the Grey-headed Flying-fox (GHFF) and the Black Flying-fox (BFF) database for NSW. The current dataset contains information on the locations of camps known to be used by grey-headed flying-foxes as of April 2008.

Please note that users should refer to the Wildlife Atlas (and any other datasets) to obtain the latest information.
