Species of greatest conservation need (SGCN) are those wildlife species whose populations are declining or naturally rare and whose continued existence requires some action.
For many species, the reduced availability of habitat contributes to their decline. Especially sensitive to habitat change are those with needs that can be met only by specific habitat characteristics such as a particular plant community, a particular hydrologic or temperature regime, or a particular size of habitat patch. Forest management activities can enhance, degrade or maintain the habitat of certain species.
Some of the SGCN are listed as threatened or endangered under the N.H. Endangered Species Conservation Act (RSA 212-A) and have some regulatory protection. Others are listed in the New Hampshire Wildlife Action Plan, with recommendations for conservation actions that can help prevent them from declining and being listed under the Act. Modification in routine silvicultural operations may benefit these species. These decisions are best made on a site-specific basis.
To sustain wildlife species of greatest conservation need in habitats where they occur and restore habitats that enable them to recover their populations.
