Abstract
A study was carried out during the year 2022-23 with a view to predict the future
distribution range of Chironji (Buchanania cochinchinensis); identify the bioclimatic
variables limiting the distribution and characterization of ecological niche in the Vindhya
region of Uttar Pradesh., Two different ecological niche models (BioClim and MaxEnt)
were applied to determine future species distribution ranges and identify limiting
bioclimatic variables for real occurrence data of 57 locations. The ecological niche of the
species was evaluated by using soil characters, present climatic conditions, population size,
topography, and identifying the associates. The GeoCAT and Digital Elevation Model
(DEM) were used to find out the population size and topography. Results of the study
showed soil pH varied from 6.46 to 7.92, Nitrogen from low (213 kg/ha) to medium (389
kg/ha), Phosphorus was medium (13.50-22.50 kg/ha), and Potassium low (84 kg/ha) to
high (662 kg/ha), with 210m to 520m elevation and population size 4.515km2
(Extent of
Occurrence) and 23 km2
(Area of Occupancy) with Mahua, Tendu, and Sal as associates.
The distribution ranges were found with 80% overlap between the baseline (2030) and
predicted (2100) habitat suitability for the focal species, which were primarily determined
by the mean temperature of the warmest quarter (Bio_10) and precipitation of the driest
quarter (Bio_17) that emerged to be the most sensitive with the contribution of 29.5% and
22.3% respectively. The present (2030) and future (2100) projections suggest 13.73 % low
suitable, 86.27 % medium suitable and 1.52 % low suitable, 98.48 % medium suitable area
respectively for the distribution and cultivation of the chironji. The findings of the study
provide insight into the suitable habitats of B. cochinchinensis for its promotion and
conservation in Banda, Hamirpur, Kaushambi, Bhadohi, Prayagraj, and Chitrakoot forest
