摘要

Community based forest restoration emerges as a powerful and inclusive strategy to reconnect the fragmented landscapes. This study focuses on restoring elephant corridors through the planting of multiple native woody tree species, aiming to enhance elephant movement, biodiversity, ecosystem services, and climate resilience. Based on preliminary reconnaissance investigations conducted in the Dering-Dibru Saikhowa elephant corridors, we identified fifty hectares of degraded land using a combination of approaches, including local knowledge, ground-truthing assessments, and elephant movement data. We planted 44,382 saplings of 31 tree species, representing 27 genera and 20 families. Hand weeding was done twice to remove alien plants (Mimosa pudica L., Mikania micrantha Kunth) from the planting landscape. The Generalized Linear Model revealed a significant positive relationship (p < 0.05) between the planted tree saplings and survival saplings after one year of plantation. Out of the total tree species, 29% of species had a high survival rate, 45% had a medium survival rate, and 26% had a low survival rate. Planted tree species such as Chionanthus ramiflorus (69.25%), Bombax ceiba (67.74%), Lagerstroemia speciosa (67.40%), Albizia lebbeck (64.03%), Dillenia indica (62.45%), Neolamarckia cadamba (58.80%), Alstonia scholaris (58.01%) had the highest survival rate and should thus be promoted for future restoration in the degraded elephant corridors of this landscape. Artocarpus heterophyllus (49.52%), Syzygium cumini (46.20%), and Phyllanthus emblica (45.60%), on the other hand, had medium survival rate, indicating that increased human intervention is required to improve their survival rate. The survival rate of planted tree species serves as a critical metric for evaluating the overall performance of restoration initiatives, as well as identifying and recommending appropriate tree species for site-specific ecological restoration. These corridors are crucial for maintaining landscape connectivity, allowing elephants and other wildlife species to migrate safely, and sustaining biodiversity in fragmented habitats.
