A decision support tool for prioritizing conservation projects.
Prioritizations can be developed by maximizing expected feature richness,
expected phylogenetic diversity, the number of features that meet
persistence targets, or identifying a set of projects that meet persistence
targets for minimal cost. Constraints (e.g. lock in specific actions) and
feature weights can also be specified to further customize prioritizations.
After defining a project prioritization problem, solutions can be obtained
using exact algorithms, heuristic algorithms, or random processes. In
particular, it is recommended to install the 'Gurobi' optimizer (available
from <https://www.gurobi.com>) because it can identify optimal solutions
very quickly. Finally, methods are provided for comparing different
prioritizations and evaluating their benefits. For more information, see
Hanson et al. (2019) <doi:10.1111/2041-210X.13264>.
