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).

READ_ME file (READ_ME_PLEASE.txt):Metadata.

不列颠哥伦比亚省水生气候避难所（aquatic climate refugia）空间优先级（版本1.0）

领地致谢：
我们谨此敬致谢忱，承认我们的工作与生活均开展于这片多样的未割让领地与条约土地之上，并向此地的原住民（First Nations）、因纽特人（Inuit）与梅蒂人（Métis）祖先致以崇高敬意。我们珍视与这片土地及水域的联结，并重申彼此间的情谊与联系。

研究目的：
以粗筛选（coarse-filter）层级（生境类型维度）为基准，识别并排序不列颠哥伦比亚省全境水生生态系统的气候避难所（climate refugia）潜力空间点位并进行分级。

数据集说明：
本数据集的栅格图层涵盖用于识别并分级不列颠哥伦比亚省水生气候避难所的所有粗筛选类别（大型气候避难所（macrorefugia）、生态完整性（intactness）与持久特征（enduring features）），以及保护等级的综合分级结果。有关研究方法的详细信息，请参阅Porter（2021）的原始报告。
