Fig. 2. Spatial distribution of selected Bioclimatic variables used for mapping and habitat suitability modelling of Dalbergia latifolia in Nepal (Table 1). These spatial products were derived from 19 original (modification was not made) bioclimatic variables developed by Hijmans et al. (2005) (posted on the Bioclim website; https://www.worldclim.org/). Scaling factor (see Table 1) is used in the units of the studied variables. (Note: “°C” is degree centigrade, “mm” is millimeter and “%” is percentage). View larger in new window/tab.

Fig. 3. The Jackknife test for evaluating the relative importance of environmental variables for Dalbergia latifolia Maxent model on habitat suitability. (Note: “ASP” is aspect; “Bio14 is Precipitation of driest period; “Bio15” is Precipitation seasonality; “Bio17” is Precipitation of driest quarter; “Bio18” is Precipitation of warmest quarter; “Bio19” is Precipitation of coldest quarter; “Bio2” is Mean diurnal range; “Bio3” is isothermality; “Bio9” is Mean temperature of driest quarter; “ELE” is elevation; “FT” is forest types and “SLO” is slope).

Fig. 4. Relationships between top environmental predictors and the probability of presence of Dalbergia latifolia in Nepal: (A) “ELE” is Elevation in Meter, (B) “Bio9” is Mean temperature of driest quarter in °C, (C) “Bio15” is Precipitation seasonality in mm and (D) “Bio19” is Precipitation of coldest quarter in mm.
