Facilitating Establishment of Advance Regeneration of Pterocarpus santalinus L.—An Endangered Tree Species from India

Red sanders (Pterocarpus santalinus L.) is an endangered and endemic tropical tree species from India in need of restoration. This study evaluated options for improving establishment of its advance regeneration in degraded forests. Using randomized complete block design, the effect of silvicultural treatments involving prescribed fire, in combination with disking, singling, disking with singling, and control (no treatment) on survival and growth of advanced regeneration were evaluated for a period of 2 years. Results indicate that the treatments served to ameliorate microsite conditions resulting in better survival and growth. Seedlings with fewer coppice shoots, treatments with a singling component, and treatments with disking component showed better survival and growth. The number and height of other neighboring seedlings and trees also influenced seedling establishment. Seedlings showed significantly higher survival results in the prescribed fire with disking (disking with prescribed burn [DPB]: 96%) and prescribed fires with disking and singling (singling plus disking with prescribed burn [SDPB]: 94%) treatments. Similarly, tall seedlings and those with larger root collar diameters accrued significantly higher volume growth in DPB (87%) and SDPB (97%) treatments. Although seedlings showed similar increments in DPB and SDPB treatments, better survival due to singling indicated the latter as the best option. In dense regeneration areas, preferential treatment of the taller and larger stump‐sized seedlings and, in limited regeneration areas that of smaller seedlings, may yield better results. Additionally, removal of competing vegetation and canopy opening may also help establishment of young regeneration. The results of this study have applications for restoration of endangered species in other tropical dry deciduous ecosystems worldwide.     

Exploring Stakeholders' Perceptions with Analytic Hierarchy Process—A Case Study of Red Sanders (Pterocarpus santalinus L.) Restoration in India

Diverse stakeholders and multiple management options pose challenges to restoration planning and management. Analytic hierarchy process (AHP), a multicriteria decision‐making tool, can be effectively used for incorporating stakeholders' perceptions in planning. By using Red sanders (Pterocarpus santalinus L.) restoration as a case study, we demonstrate its suitability in eliciting stakeholders' perceptions about the most suitable management option, and their expectations from it. Four key stakeholder groups, Administrators, Field Officers, Community, and Knowledgeable Sources, were used to identify the most suitable management option from Government Management (GM), Quasi‐Government Management, Community Forest Management (CFM), and Private Management. Results indicate that stakeholders' preferences for management options were not homogeneous. Consolidated priorities across all the stakeholder groups indicated the CFM (34%) as the most preferred option followed by the GM (31%). With an average weight of 56%, the ecological criterion was considered as the most important. The ability of the managements in reducing disturbances (23%), improving Red sanders density (18%), improving ecosystem services (15%), and in improving rural livelihoods (15%) were considered important. The preferences of the Administrators and the Field Officers for the GM indicated their support for the top‐down management approach, and skepticism toward the CFM, a bottom‐up approach. Compared to the Administrators, the Field Officers' lack of support for the CFM was surprisingly more pronounced. Results indicate the usefulness of the AHP technique in identifying common grounds between the diverse stakeholders, and the management, in identifying a suitable management alternative and in prioritizing preferences.
