This dataset shows the modelled regional connectivity links for generalist species (birds and small mammals). Based local corridor values based on least cost paths through a local links dataset (see Barrett and Love 2012) at 2012. Categories indicate quality of regional connectivity between larger high value habitat patches.
Dataset has been re-categorised from the original raster data source to eliminate "no value" cells and converted to a vector.
Regional Linkage Value: This layer is derived from a two-step process. The first process is a “join the dots” links analysis using 550,000 paths between point pairs selected at random. Points were grouped in high value woodland habitat patches only. This least cost pathway analysis was then run through the local links paths, that is regional links were preferentially routed along paths that did not have a canopy gap of >100m. High values indicate that more paths were found, i.e. more important for regional connectivity between high value habitat patches.
connectivityLinkageValue:
Represents the categorisation of the "accumulated least cost pathway" value for each linkage between habitat patches. Least cost pathway indicates the a combination of habitat suitability of nodes along the path, and a the barriers to migration along that pathway.
The ACT connectivity mapping was undertaken by the NSW Office of Environment and Heritage. A full study report has been produced, and is entitled Fine Scale Modelling of Fauna Habitat and Connectivity Values in the ACT Region (Barrett and Love 2012). This study built upon an earlier report entitled the Ecological Connectivity for Climate Change in the ACT and surrounding region, commissioned by the ACT Government as part of Weathering the Change Action Plan 1. The report was undertaken by the Fenner School of Environment and Society, Australian National University (Manning et al 2010). It is recommended that both reports be consulted when use is being made of the connectivity mapping available. Reports can be downloaded from the EPSDD website at https://www.environment.act.gov.au/nature-conservation/conservation-research/research-and-technical-reports (Technical reports 21 and 27).
Updates: This dataset is static.
Fit for purpose: 2012 temporal coverage. This dataset should be used as a modelled tool for aiding landuse, strategic town planning, and conservation planning in the ACT including revegetation targets and informing environmental impacts of infrastructure and building projects. Cell size 15x15m.
