Valuing habitat regime models for rare, threatened, and endangered species in Mississippi.

摘要

Scenario planning and Geographic Information Systems (GIS) were used to estimate timber/habitat relationships for gopher tortoise (Gopherus polyphemus), Louisiana black bear (Ursus americanus luteolus ), and red-cockaded woodpecker (RCW) (Picoides borealis) for industrial land, nonindustrial private, and government forest land ownerships in Mississippi. The 2000 U.S. Forest Service (USFS) Resource Planning Act (RPA) and Forest Inventory and Analysis (FIA) data were analyzed using USFS forest planning software, Spectrum, and GIS software, ArcView, to determine these relationships in various physiographic regions.; Maximizing Net Present Value (NPV) produced higher Land Expectation Values (LEVs) and Equal Annual Incomes (EAIs) for gopher tortoise and RCW, across all ownerships. LEV and EAI for wildlife were lower due to revenue forgone largely through differences in harvesting schedules. For Louisiana black bear, wildlife objectives out produced the NPV only objective for LEV and EAI. In all cases, wildlife management objectives produced more habitat acres than those maximizing NPV.
