Resource allocation for land acquisition is a common multiobjective problem that involves complex trade-offs. The National Wildlife Refuge System (NWRS) of the U.S.

A spatial model for the beneficial use of dredge spoil deposition: Creation and management of breeding habitat for reddish egrets in Texas.

Many species of coastal waterbirds have faced population declines in recent years as a result of loss and degradation of habitat. The creation of new habitat through strategic placement of dredge spoil can be an effective tool to mitigate habitat loss. The use of dredge spoil islands for nesting, wintering, and migratory stopover habitat by waterbirds has been documented extensively over the past several decades.
