Spatial priorities for aquatic climate refugia in British Columbia (Version 1.0)

Spatial priorities for aquatic climate refugia in British Columbia (Version 1.0) Territorial acknowledgement: We respectfully acknowledge that we live and work across diverse unceded territories and treaty lands and pay our respects to the First Nations, Inuit and Métis ancestors of these places. We honour our connections to these lands and waters and reaffirm our relationships with one another. Suggested citation: Stolar, J., C. Kuntzemann, C. Enslow, S. Lees, D.W. Lewis, D. Stralberg, G.

Place of publication: University of Alberta, Edmonton, Canada. doi: 10.5281/zenodo.10871083 Corresponding author: [e-mail] Purpose: To identify and rank spatial locations of refugia potential for aquatic ecosystems across British Columbia at the coarse-filter level (habitat types). Description: These raster layers represent each coarse-filter category (macrorefugia, intactness, and enduring features) for identifying and ranking aquatic climate refugia in British Columbia plus the overall rankings of conservation classes. For details on the methodology, please see the original report by Porter (2021). File nomenclature: .zip folder (Stolar_et_al_2024_CiCP_aquatic_upload_Version_1.0.zip):Contains the files listed below. Macrorefugia (macrorefugia_1_ha.tif):Inverse of the sum of forward and backward climate velocity (Stolar et al., 2023). Macrorefugia by watershed (macrorefugia_by_watershed.tif):macrorefugia_1_ha.tif summarized by watershed. Intactness (intactness_1_ha.tif):Inverse of footprint metrics as described by Porter (2021). Intactness by watershed (intactness_by_watershed.tif):intactness_1_ha.tif summarized by watershed. Enduring features with microrefugia potential (sum_enduring_1_ha.tif):Sum of enduring features that represent microrefugia potential for aquatic ecosystems (Porter, 2021).***PLEASE NOTE: It has been discovered that the provincial Quaternary geology layer is mislabeled. We will update the analysis with a more accurate layer for this metric in the next version. Enduring features with microrefugia potential by watershed (sum_enduring_by_watershed.tif):sum_enduring_1_ha.tif summarized by watershed. Conservation classes (overall_ranking_1_ha.tif):Range of conservation classes based on the combination of metrics list above as described in Table 5 by Porter (2021).
