Landscape Conservation Cooperatives use a collaborative approach to identify landscape scale conservation solutions. LCCs work across jurisdictional and political boundaries to work with partners to: meet unfilled conservation needs, develop decision support tools, share data and knowledge, and facilitate and foster partnerships.
As part of a shared science strategy, LCCs coordinate closely with the National Climate Change and Wildlife Center and the eight regional Climate Science Centers.

One common way to conduct species vulnerability assessments (VA) to climate change (CC) is to model species distributions and predict CC-related range shifts.
The objective of this experimental research is to determine if genetic enrichment may enhance survival, growth, and adaptation of important native Hawaiian montane plant species to changing precipitation patterns by relocating conspecifics to more favorable climate regimes at higher elevation.
The specific objectives of this contract are to identify and categorize key differences and similarities between islands and continental systems that are relevant to achieving sustainable landscapes/seascapes at regional scales; to develop a conservation framework that integrates planning process
