Resilience concerns the ability of a living system to adjust to climate change, moderate potential damages, take advantage of opportunities, or cope with consequences; in short, the capacity to adapt. The Nature Conservancy’s resilience analysis develops an approach to conserve biological diversity while allowing species and communities to rearrange in response to a continually changing climate. See more at: http://nature.org/climateresilience. In the Resilient and Connected Network analysis, sites and linkages identified by the combination of resilience, flow, and biodiversity were integrated into a single network. The network is designed to represent resilient examples all the characteristic environments of the region while maximizing amount of diversity contained within in them and the natural flow that connects them. By building the network around the natural pathways that allow species populations to shift and then identifying representative resilient sites situated within those pathways, the network is specifically configured to sustain biological diversity while allowing nature to adapt and change.
The Recognized Biodiversity Value dataset was compiled and used to identify which portions of the Resilient and Connected Network contained areas recognized for exemplary natural habitats and/or populations of current biodiversity. Our hypothesis is that to have the highest likelihood to sustain biological diversity into the future, we wanted the network to be composed of climate resilience sites that contained the maximum amount of current biodiversity. The Recognized Biodiversity Value dataset includes lands recognized for biodiversity values including those from ecoregional-based conservation planning efforts (TNC, NCC), state-based conservation planning analyses (Conservation Opportunity Areas from State Wildlife Action plans or other state-based biodiversity analyses), lands secured from conversion to development under protected GAP1 or GAP 2 level management for nature conservation, and in some areas... |

We assessed how well these two sets of maps represented the full suite of geophysical settings. In cases where specific geophysical settings were not well represented in these mapped priorities, we supplemented these maps with known occurrences of rare species and communities (NatureServe element occurrences, or EOs) when available; otherwise, for those settings, we identified the largest areas of very high estimated resilience within the relevant ecoregion. We also supplemented these maps by including lands secured from conversion to development under protected GAP1 or GAP 2 level management for nature conservation. This was an important step because in some of the TNC Ecoregional portfolios already protected land (such as Yosemite National Park) were excluded from the portfolio map to focus on new protection. We added all GAP1 and 2 secured lands to the recognized biodiversity values areas given their primary management goals to maintain high quality habitat, natural processes, and thriving species populations. GAP 1 managed lands have as their intent "Nature conservation, with little human interference”. Examples include Research Natural Areas (RNA), Wilderness Areas and Wilderness Study areas, Forever Wild easements, and some TNC preserves where TNC controls management. GAP 2 lands have as their intent "Nature conservation, with heavy management where needed". Examples include National Wildlife Refuges, Areas of Critical Environmental Concern, some National Park land or National Monuments, US Forest Service Special Interest Areas, and some TNC conservation easement lands and preserves.</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>The final Recognized Biodiversity Value dataset is a 30m raster which includes the following four values:</SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>1: Ecoregion-based</SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN><SPAN>2: Ecoregion and State-based</SPAN></SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>3: State-based</SPAN></P><P STYLE="margin:0 0 14 0;"><SPAN>4: Additional Habitat and Species Areas, not already included in the above categories of Ecoregion or State-based </SPAN></P><P /><P STYLE="margin:0 0 14 0;"><SPAN /></P><P><SPAN /></P></DIV></DIV></DIV> |
