BMAS
The Biodiversity Management Area Selection (BMAS) Model is a general spatial model, developed for the selection of biodiversity management areas in the Sierra-Nevada Region. Biodiversity Management Areas are specially designated public or private lands with an active ecosystem management plan in operation whose primary purpose is to contribute to regional maintenance of native genetic, species and community levels of biodiversity, and the processes that maintain that biodiversity. The primary management goal in each BMA is to sustain native biodiversity. BMAS is a model used to select BMAs. This model is loosely integrated with a GIS system. The basic modeling approach begins by first identifying those plant communities that are vulnerable due to land use activities in current management plans. The level of vulnerability is assessed for each element of interest on a spatial basis using ARC/INFO. The planning problem involves selecting an efficient set of watersheds or planning units for biodiversity management through specially developed heuristics and the general purpose integer-linear programming software packages. The BMAS model implements advanced GIS-based conservation planning, and allows integration of cultural and land use data with biological data.BMAS addresses the following environmental issues in developing a BMA strategy for the Sierra Nevada:1. What is the minimal area required to represent all Sierran plant community types in BMAs? How does an "optimal" BMA system compare to the existing set of parks, wilderness areas and reserves in the region? 2. Can a representative BMA system be established on public lands only? If not, what area of private lands is required? How does the area requirement change if lands that are currently administratively withdrawn from grazing and timber harvest are classified as BMA lands? 3. How sensitive is the siting of BMAs to the way in which biodiversity is measured? Specifically, how do solutions to represent plant community types compare to solutions based on representing vertebrate species?

C-Whiz Linear Programming (LP) Software
ARC/INFO: The level of vulnerability is assessed for each element of interest on a spatial basis. General purpose integer-linear programming software, such as ILOG-CPLEX or Ketron’s C-Whiz. The planning problem involves selecting an efficient set of watersheds or planning units for biodiversity management and can be solved either optimally or through specially developed heuristics.
