Description and Rationale

Through the use of satellite imagery and GIS data layers, landscape dynamics monitoring in Pacific Island Network (PACN) parks provides information on land use and land cover change. This monitoring protocol differentiates between natural and anthropogenic causes of land-condition change and allows natural resource managers to understand changes in land cover, pollution sources, avenues for exotic species, and other changes in surrounding lands.

Monitoring Objectives

  1. Document landscape dynamics for PACN parks every 10 years, identifying spatial and temporal characteristics of land use / land cover changes. A remote sensing based change vector analysis will be used to identify areas that have changed since the last analysis. Finer scale or field data will then describe change conditions.
  2. Map the distribution and density of infrastructure (e.g., roads and developments) within the wildland-urban interface of PACN parks every 5 years.
  3. Use tax assessor and US Census Bureau data, in addition to the current land use data identified above, to map the distribution and density of human habitation (e.g., population and housing density) within the wildland-urban interface surrounding PACN parks every 3-10 years.
