Baseline and Future Habitat Suitability Maps for Tree Species Prioritized for Food Tree Portfolios for Zambia

<p>This archive includes habitat suitability maps for six native food tree species (<em>Anisophyllea boehmii</em> Engl., <em>Parinari curatellifolia</em> Planch. ex Benth., <em>Strychnos cocculoides</em> Baker, <em>Tamarindus indica </em>L., <em>Thespesia garckeana </em>F.Hoffm. [syn. <em>Azanza garckeana </em>(F.Hoffm.) Exell &amp; Hillc.] and <em>Uapaca kirkiana</em>|M&uuml;ll.Arg.|) and four exotic food tree species (<em>Carica papaya</em> L., <em>Mangifera indica</em> L., <em>Persea americana</em> Mill. and <em>Psidium guajava</em> L.). These species had been prioritized by the project. Species suitability modelling followed the BIOCLIM algorithm whereby a climate suitability score is calculated that reflects the core distribution (5% - 95%) and the marginal distribution (0% - 5% or 95% or 100%) of a species in environmental space. The BIOCLIM algorithm was expanded to reflect the middle of the environmental range (25% - 75%).</p> <p>Species suitability was inferred through bioclimatic ranges documented in the Tree Globally Observed Environmental Ranges database (TreeGOER; Kindt <a href="https://onlinelibrary.wiley.com/doi/10.1111/gcb.16914">2023</a>). Baseline suitability maps used the historical climate documented by WorldClim 2.1 (Fick &amp; Hijmans <a href="https://doi.org/10.1002/joc.5086">2017</a>). Future suitability maps correspond to a low emissions scenario (Shared Socio-Economic Pathway [SSP] 1-2.6) and a high emissions scenario (SSP 3-7.0), both calculated as medians from Global Climate Models (GCM) projections for the 2050s (2041-2060) available from WorldClim 2.1 (respectively from 23 and 18 GCMs).</p> <p>For larger sets of tree species native to Zambia, it has recently become possible to filter tree species by bioclimatic conditions of the planting site with the GlobalUsefulNativeTrees database (GlobUNT; Kindt et al. <a href="https://www.nature.com/articles/s41598-023-39552-1">2023</a>). The GlobUNT database internally uses TreeGOER environmental ranges and the same BIOCLIM algorithm that was used the generate the habitat suitability maps. Included in this archive is a list of native tree species to Zambia that were filtered for the use category of human food.</p> <p>&nbsp;</p> <p>When using these maps, cite the following:</p> <p>&middot;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Fick, S.
