Aggregating high-priority landscape areas to the parcel level: An easement implementation tool

Landscape characteristics and parcel ownership information are often collected on different spatial scales leading to difficulties in implementing land use plans at the parcel level. This study provides a method for aggregating highly resolute landscape planning information to the parcel level. Our parcel prioritization model directly incorporates a Land Trustʹs conservation goals in the form of a compromise programming model. We then demonstrate the use of our approach for implementation decisions, including parcel selection under a budget constraint and the estimation of a total conservation budget necessary to meet specific conservation goals. We found that these cost constraints significantly alter the composition of the ‘best’ parcels for conservation and can also provide guidance for implementation. The modelʹs results were integral to a local Land Trustʹs ability to further define and achieve their goals.
