Abstract 
The Baluchistan Black Bear (BBB), a critically endangered subspecies (CR), is distributed in the southeastern Iran. Modelling of landscape connectivity of the BBBs among habitat patches can be insightful for the conservation managers working in Iran. Our study was designed to identify the potential corridors among 31 habitat patches of the BBBs in Iran using the circuit theory method. Habitat suitability map was generated in MaxEnt using 101 presence points and nine environmental variables, which were later inversed and used in corridor modeling. By using the circuit theory method, areas of high migration density were compared with four clusters determined in a previous study based on the least-cost model. Three main clusters with the high migration density of BBB were detected. Moreover, we identified eight insular habitat patches of the species that required urgent management actions to connect with other patches in the southeastern Iran. Circuit theory method clearly confirmed the main clusters introduced for the conservation of the BBBs in the southeastern Iran. Results of this study could be, therefore, used as a suitable pattern for the conservation priorities of BBBs habitats in this part of Iran.

    Abstract




				

					
The purpose of this study was to analyze the strengths, weaknesses, threats and opportunities in the conservation of Baluchistan black bear in the south of Kerman province using the quantitative and qualitative approaches and presenting the sustainable strategic management program for conservation of this species. Using questionnaire, a list of internal and external environmental factors was compile. The relative importance of these factors was weighted and the Strategic Position and Action Evaluation (SPACE) matrix were drawn and then, the various initial strategies were quantified with the formation of the strategic planning matrix. A total of 11 internal strengths, 4 internal weaknesses, 5 external opportunities and 4 external threats were identified. The final score of the internal factors matrix (IFE = 2.01418) shows that, the weaknesses are more than the strengths and the score of the external factors matrix (EFE = 2.07462) shows that there are more threats than opportunities in solving the conflict problem. The results of the SPACE matrix showed that the defensive strategies should be used for the protection of the Black bear in the south of Kerman province. Implementation of environmental assessment studies for development projects in the Black bear habitats was determined as the first modified solution.

    Abstract




				

					
Habitat analysis using landscape metrics can be efficient in better management of habitat. As a critically endangered subspecies, the Baluchistan black bear is scattered in the Bahr Asman and Zaryab areas in Kerman province. The purpose of this study was to model the distribution of the sub-species and evaluate the quality of its habitat patches, using landscape metrics. Distribution modeling was conducted using an ensemble approach, resulting from the combination of presence-only and presence/pseudo-absence data in ModEco software. True Skill Statistic (TSS) threshold was applied to the ensemble model and the habitat patches were analyzed, using landscape metrics. The results showed that the distribution rage is beyond the border of the studied protected areas and the variables related to humidity had the greatest effect on the presence of the species. Based on the metrics analysis, habitat patches in the Zaryab wildlife refugee have higher connectivity and less margin than Bahr Asman protected area. In Bahr Asman protected area, the number of habitat patches is greater than the Zaryab wildlife refugee and the lack of continuity among the patches has led to the edge formation. The results of this study can be used for the habitat management of this critically endangered subspecies
