MARTEN UPDATE
Management strategies can include:Specific strategies for habitat patchesLooking at linkage corridors – riparian or otherIdentifying barriers to movement between core patches of habitat and potential solutionsRetention of key habitat features for denning and resting sites – snags, logs, diseased/damaged treesMaintain and/or increase landscape heterogeneity while maintaining core patches and linkages
