Area of Science:

  • Ecology
  • Conservation Biology
  • Geographic Information Systems (GIS)

Background:

  • Existing conservation lands may not adequately represent all native species and natural communities.
  • The United States Geological Survey Gap Analysis Program (USGS GAP) aims to identify these conservation gaps nationwide.
  • Biological diversity loss is a significant environmental concern requiring targeted conservation efforts.

Purpose of the Study:

  • To assess the representation of native animal species and natural communities within Florida's conservation lands.
  • To identify "gaps" in conservation land networks where species or communities are not adequately protected.
  • To provide geographic information on the status of terrestrial vertebrates, butterflies, skippers, and ants, and their habitats in Florida.

Main Methods:

Related Experiment Videos

  • Mapped natural land cover to the level of dominant or co-dominant plant species using Landsat TM satellite imagery and auxiliary data.
  • Classified land cover using data from the National Wetlands Inventory (NWI), soils maps, aerial imagery, and ground surveys.
  • Developed wildlife distribution models by identifying suitable habitats within species' ranges, including minimum critical area assessments for mammals.

Main Results:

  • Identified specific "gaps" in conservation land coverage for various native species and natural communities in Florida.
  • Generated detailed wildlife distribution models for terrestrial vertebrates, butterflies, skippers, and ants.
  • Summarized wildlife species richness against land stewardship, prioritizing areas with strong conservation mandates.

Conclusions:

  • The Florida Gap (Fl-Gap) project provides critical data for enhancing biodiversity conservation strategies in Florida.
  • Understanding these conservation gaps is essential for prioritizing land acquisition and management efforts.
  • The findings support informed decision-making to improve the effectiveness of Florida's conservation land network.
