Forest fires are common in Uttarakhand, Western Himalaya, causing substantial harm to forests and ecosystems. This study aimed to assess vegetation recovery across three high-risk forest types in Uttarakhand. We conducted vegetation surveys before and after the fire season to analyze vegetation structure, diversity, and regeneration potential at each site. Non-metric Multidimensional Scaling (NMDS) was employed to evaluate species diversity. The results indicated that post-fire regeneration varied significantly between sites. The high-elevation mixed forests showed the most remarkable recovery of vegetation cover and diversity. In contrast, the lower-elevation Sal and Chir-pine forests exhibited slower recovery rates and reduced diversity. Fire severity was also a key factor influencing vegetation recovery, with areas experiencing more intense fires recovering more slowly. These findings highlight the need for ecosystem-specific management strategies to enhance post-fire recovery. Management approaches should be tailored to each ecosystem, considering forest type, elevation, and fire severity factors. The study underscores the importance of preventive measures, including controlled burning, to reduce the risk of forest fires and improve ecosystem resilience in Uttarakhand and other fire-prone regions.

摘要

Forest fires are common in Uttarakhand, Western Himalaya, causing substantial harm to forests and ecosystems. This study aimed to assess vegetation recovery across three high-risk forest types in Uttarakhand. We conducted vegetation surveys before and after the fire season to analyze vegetation structure, diversity, and regeneration potential at each site. Non-metric Multidimensional Scaling (NMDS) was employed to evaluate species diversity. The results indicated that post-fire regeneration varied significantly between sites. The high-elevation mixed forests showed the most remarkable recovery of vegetation cover and diversity. In contrast, the lower-elevation Sal and Chir-pine forests exhibited slower recovery rates and reduced diversity. Fire severity was also a key factor influencing vegetation recovery, with areas experiencing more intense fires recovering more slowly. These findings highlight the need for ecosystem-specific management strategies to enhance post-fire recovery. Management approaches should be tailored to each ecosystem, considering forest type, elevation, and fire severity factors. The study underscores the importance of preventive measures, including controlled burning, to reduce the risk of forest fires and improve ecosystem resilience in Uttarakhand and other fire-prone regions.
