Adaptive management is a management approach to address uncertainty in natural resources. The origin of the adaptive approach as a tool, the need for an adaptive process and its relationship to environmental management will be described. Variations of adaptive management will be reviewed as well as the definition and institutional role of adaptive management within the BLM. This will include th...
Management of natural resources in coastal ecosystems is a complex process that is made more challenging by the need for stakeholders to confront the prospect of sea level rise and a host of other environmental stressors. This situation is especially true for coastal military installations, where resource managers need to balance conflicting objectives of environmental conservation against mili...

More than fifty percent of the original wetlands in the United States were lost by the 1980s and more have been lost or greatly altered since (Gibbs 2000), while more than ninety percent of the riparian areas...
The restoration achieved on the basis of a Wiener scheme is an optimum since the restoration filter is the outcome of a minimisation process. Moreover, the Wiener restoration approach requires the estimation of some parameters related to the original image and the noise, as well as knowledge about the PSF function. However, in a real restoration problem, we may not possess accurate values of th...
Restoration strategies for native oyster populations rely on multiple sources of information, which often conflict due to timeand space-varying patterns in abundance and distribution. For instance, strategies based on population connectivity and disease resistance can differ, and extant and historical records of abundance and distribution are often at odds, such that the optimal strategy is unc...
