Baseline and Future (2050s and 2090s) Climate Suitability Scores for 116 Useful Tree Species and 220 locations from Côte d'Ivoire, Ghana and Guinea (Q9640)

Climate suitability scores were calculated for 116 Useful Tree Species identified by filtering Top830+ native tree species from Cte d'Ivoire, Ghana and Guinea via the GlobalUsefulNativeTrees database and checking for the availability of globally observed environmental ranges from the TreeGOER database. Score = 3 means that in 'environmental space' the planting site occurs within the 25% - 75% species's range (as documented in theTreeGOER ) for all variables Score = 2 corresponds to the 5% - 95% species's range for all variables. For some variables, the planting site occurs outside the 25% - 75% species's range. Score = 1 corresponds to the 0% - 100% species's range for all variables. For some variables, the planting site occurs outside the 5% - 95% species's range. Score = 0 means that the planting site occurs outside the 0% - 100% species's range for some of the variables Score = -1 means that the species is not documented by TreeGOER Locations corresponded to cities and weather stations from the three target countries sourced from the CitiesGOER and ClimateForecasts databases, respectively. Both these databases provide bioclimatic conditions for the historical (baseline) and three future climate change scenarios. Bioclimatic variables for future climates correspond to the median values from 24 Global Climate Models (GCMs) for Shared Socio-Economic Pathway (SSP) 1-2.6 for the 2050s (2041-2060), from 21 GCMs for SSP 3-7.0 for the 2050s and from 13 GCMs for SSP 5-8.5 for the 2090s. Investigations were made for two different sets of bioclimatic variables, allowing for sensitivity analysis: One set of bioclimatic variables included BIO01 (mean annual temperature), BIO12 (total annual precipitation), climaticMoistureIndex, monthCountByTemp10 (number of months with average temperature above 10 degrees), growingDegDays5, BIO05 (maximum temperature of the warmest month), BIO06 (minimum temperature of teh coldest month), BIO16 (precipitation of the wettest quarter), BIO17 (precipitation of the driest quarter) and MCWD (Maximum Climatological Water Deficit). These are the same bioclimatic variables available internally in the GlobalUsefulNativeTrees for climate filtering. One set only included BIO01 (mean annual temperature), which is the single bioclimatic variables available for the BGCI Climate Assessment Tool. Calculations were made with similar scripting pipelines in the R statistical environment as documented here: https://rpubs.com/Roeland-KINDT/1168650. These scripts use similar calculations methods as those used for the global case studies of the TreeGOER manuscript (Kindt 2023), and used internally in the GlobalUsefulNativeTrees online database. Interested readers should especially refer to the manuscript for further details on methods used and their justification. The maps show the frequency distribution of tree species with climate scores 3, 2, 1 and 0, excluding 18 species not documented by the TreeGOER. References Kindt, R. (2023).
