Rebalanced Middle Southeast input to Southeast Blueprint 2020
Summary
This is the exact layer used as an input to Southeast Blueprint 2020 for the Middle Southeast geography. It was derived from Middle Southeast Blueprint 2020. Please note: Southeast Blueprint 2021 used the full Middle Southeast Blueprint 2020 layer instead of this one to correct an error with the spatial rebalance described in the known issue below. Middle Southeast Blueprint 2020 extends into parts of IL, KS, TX, and OK. As a result, the entirety of Middle Southeast Blueprint 2020 was not used in Southeast Blueprint 2020. IL and KS are outside the SECAS geography, and only WAFWA CHAT data was used in TX and OK according to the integration rules described in the Southeast Blueprint 2020 documentation. To ensure that the Southeast [...]
Summary
This is the exact layer used as an input to Southeast Blueprint 2020 for the Middle Southeast geography. It was derived from Middle Southeast Blueprint 2020. Please note: Southeast Blueprint 2021 used the full Middle Southeast Blueprint 2020 layer instead of this one to correct an error with the spatial rebalance described in the known issue below.
Middle Southeast Blueprint 2020 extends into parts of IL, KS, TX, and OK. As a result, the entirety of Middle Southeast Blueprint 2020 was not used in Southeast Blueprint 2020. IL and KS are outside the SECAS geography, and only WAFWA CHAT data was used in TX and OK according to the integration rules described in the Southeast Blueprint 2020 documentation.
To ensure that the Southeast Blueprint prioritized closer to 50% of this subset of the Middle Southeast geography (excluding IL, KS, TX, and OK), the priorities in Middle Southeast Blueprint 2020 were spatially rebalanced across this more limited extent. The final high and medium combined CVI categories shown in this layer were recomputed from the Aquatic CVI and Terrestrial CVI datasets that form the foundation of Middle Southeast Blueprint 2020. For details about how this layer was computed, contact Middle Southeast Blueprint Science Coordinator, Todd Jones-Farrand (david_jones-farrand@fws.gov).
The final values for the rebalanced Middle Southeast input to the Southeast Blueprint are found in the “M_SEBcode” field of this dataset as follows:
0 = Unavailable (urban areas and open water)
1 = High CV
2 = Medium CV
3 = Low CV
Known Issue from 2020 Southeast Blueprint*
In the Middle Southeast input to the Southeast Blueprint, an error was made in the spatial rebalancing process. As a result, areas with high aquatic value, but low terrestrial value, are undervalued across in the final Southeast Blueprint compared to their priority in Middle Southeast Blueprint 2020. This error in the ranking process is easily correctable, but was discovered too late in the process of finalizing the Southeast Blueprint to be fixed in time for the official release at SEAFWA. We recommend that anyone in the Middle Southeast geography who wants to use the Blueprint to support their conservation decisions use Middle Southeast Blueprint 2020 directly instead of the full Southeast Blueprint.
*Again, the 2021 Southeast Blueprint corrected this issue by using the full Middle Southeast Blueprint 2020 instead, which did not have the rebalancing error.
