  • Patch Size

    • Remove all patches that are not big enough to support at least 1 pair of birds

  • Clusters of Patches

    • Determine which patches are close enough in proximity to allow dispersal between patches

Does this cluster contain enough pine forest support a minimal viable population (MVP) of RCWO?

Yes.

In this model we assume that 1000 ha of habitat could support a MVP (if it were maintained appropriately). This cluster contained 1,472 ha of Evergreen/Mixed Forest.

Clusters containing patches that are close enough for dispersal

  • Patch Size

    • Remove all patches that are not big enough to support at least 1 pair of birds

  • Clusters of Patches

    • Determine which patches are close enough in proximity to allow dispersal between patches

Only patches inside a cluster large enough to support an MVP are identified as potential targets for management in the DST

  • Individual patches are then ranked by size

    • Patches were given values based on their capability to support an MVP (% MVP)

    • A value of 100% indicates a patch could support 1 (or more) MVPs

    • A value of 50% indicates a patch could support 50% of an MVP

  • Patch Size

    • Remove all patches that are not big enough to support at least 1 pair of birds

  • Clusters of Patches

    • Determine which patches are close enough in proximity to allow dispersal between patches

Does this cluster contain enough pine forest support a minimal viable population (MVP) of RCWO?

Yes.

In this model we assume that 1000 ha of habitat could support a MVP (if it were maintained appropriately). This cluster contained 1,472 ha of Evergreen/Mixed Forest.

Draft user guidelines for the open pine management dst
Draft User Guidelines for the Open Pine Management DST

  • A decision support tool (DST) is used to help inform, guide and support habitat planning decisions. It is not designed to make the decision for the user of the DST

  • The Open Pine management DST is designed for landscape scale planning decisions (parish/county or greater planning unit). It cannot be used to prioritize small tracts of land for acquisition, management and/or cost-share programs.

  • The Open Pine DST can be used to develop focal areas for management, acquisitions and planning for conservation.

  • Habitat types are based on 2001 National Land Cover Data (NLCD). The NLCD may not have been ground truthed for all areas and local managers may find erroneous classifications for their particular tract(s) of land. Currently, no other comprehensive data set with greater accuracy exists to replace NLCD.

  • Four umbrella species’ habitat requirements were used to develop the minimum patch size for the Open Pine DST: red-cockaded woodpecker (Picoides borealis), bobwhite quail, Bachman’s sparrow and brownheaded nuthatch.

  • The model used the following minimum viable population (MVP) values for each of the umbrella species

    • 20 - red-cockaded woodpecker

    • 50 - Bachman’s sparrow

    • 28 - brownheaded nuthatch.

  • The final model spatial layer is a combination of the individual models for the four umbrella species. The values in the final spatial layer range from 0 – 400. A value of 0 in the final model indicates that, according to the model, this area does not have the potential to contribute to a MVP for any of the four umbrella species. A value of 400 in the final model indicates that, according to the model, this area is situated in the landscape in such a way that if it and the surrounding areas are managed as open pine this area will contribute to a MVP for all of the four umbrella species.

  • The individual species layers that were used to create the final model are also available for downloading and viewing. These layers are informative if you want to understand how each of the umbrella species influenced the final model. The values displayed in these layers are hectares. These values in these layers range between zero and the hectares required to support a MVP for that species. For example we can look at bobwhite quail. In the model we used a density value of 20 ha per pair and an MVP value of 60, so we say that a patch of 1200 ha (20 x 60) would support a MVP. Therefore, the values for the bobwhite quail output have a range between 0 and 1200.
