17. Mathematical Methods for Identifying Representative Reserve Networks

in a dynamic framework, such as stochastic dynamic programming, may be harder
to justify for potential users, because their computational complexity gives them a
“black box” nature.
There are a wide variety of extensions to these problems that are only now
being studied. Complex spatial requirements and reserve design under uncertainty
are only two such avenues. Other areas of interest include problems in which
species or other objectives have different weights (values) and there is a fixed
amount of land to be set aside and problems that attempt to simultaneously
optimize multiple services (e.g., when a species has one value, say, for ecotourism, when it is in a reserve, and a different value, say, for trophy hunting, when it
is outside a reserve). Solutions to these problems—even approximate solutions—
will improve the design of effective reserve networks and, ultimately, will contribute to better protection for biodiversity.
