Appendix 1. Data Table Comparing the Overlap Between Testing and Training Data Used In

Appendix 1. Data table comparing the overlap between testing and training data used in the analysis.

Table A1. Overlap between testing and training data was minimized for each species, but occurred in some 50 km grid cells with limited data.
