Restoration of the Forest Landscape of SGNP (Mulund region)
Introduction
Natural regeneration is a biological process that can be assisted and managed to increase forest cover and associated ecosystem services. Assisted Natural Regeneration (ANR) is a simple, low-cost restoration method that can effectively enhance the productivity and ecosystem functions of deforested or degraded lands. The method aims to accelerate, rather than replace, natural successional processes by removing or reducing barriers to natural regeneration such as soil degradation, competition with weedy species, and recurring disturbances.
Sanjay Gandhi National Park was selected for ANR interventions as the park is grappling with encroachment throughout its boundary which resulted in a loss of tree cover. The park is situated partly in Thane District and (59.24 Sq.Km.) and in Mumbai Suburban District (44.44 Sq.Km.) of Maharashtra State. Khindipada, the eastern end of SGNP for this project was chosen for the interventions.
The site is largely a dry deciduous habitat with undulating terrain. Its habitat is largely fragmented towards the boundary side which is surrounded by various hutment colonies. The habitat is largely dominated by Palmyra Palms which is intersected with various seasonal streams. Several open patches resulted in a fragmented canopy cover. Fragmented patches form numerous canopy gaps. Disturbed canopy cover impacts the understorey and affects the biota thriving on the forest floor.
The habitat is devoid of perennial undergrowth therefore the land is largely exposed. As the forest dept, is keen to increase the green cover throughout the park range, this could be a potential site where the ANR process could be utilised to improve the ground cover or understorey as well as the local biodiversity. Before initiation of the project, the potential sites were surveyed in the area wherein the plantation can carry out to enhance the local biodiversity.

Our Conclusion of Restoration of the Forest Landscape of SGNP (Mulund Region)tory
The advancements and achievements at Sanjay Gandhi National Park throughout this project have been significant. The establishment of flourishing deer browsing zones and thriving Pollinators zones has successfully attracted a diverse array of biodiversity, underscoring the positive impact on the local ecosystem.
The implementation of ANR intervention has yielded favorable results, fostering the natural regeneration of wild species, while the removal of invasive species further bolster the growth of native vegetation. Additionally, the fireline construction and repair of fences and tree guards have ensured the survival of plants. Strategically placed water bowls have become focal points, attracting various mammals and bird species to the park. The installation of exhibits and signages along the three trails has enriched the visitor experience. The project has made significant strides in promoting ecological restoration, engaging the community, and conserving biodiversity. The collective efforts of volunteers, successful plantation initiatives, and the active documentation of flora and fauna have contributed to the overall success of the project.

Project Interventions
Baseline Surveys
Baseline Surveys
Baseline Surveys
Biodiversity Survey: Comparing the before and after scenarios depicted, there is a significant rise of 52% in plant species, 48% in insect species, and 52% in bird species. The species composition, indicates insect diversity constituting 35% and plant diversity at 31% of the total, followed by birds at 21%. Further we recorded nine threatened species; two birds, two mammals, two reptiles and three plant species. This increases the conservation status for the habitat.
Overall, the soil analysis highlighted dynamic changes in nutrient levels that can significantly influence plant growth and ecosystem dynamics.

Naturalist Training Programme
Naturalist Training Programme
Our project is nearing completion, therefore we've decided to teach 13 naturalists as part of our naturalist training programme. In this session, participants learned about Sanjay Gandhi National Park and its biodiversity. There were two sessions, the first of which featured a Live Nature trail on SGNP and the second a virtual lecture on biodiversity. As the event concluded, we gave our Naturalist with a Certificate and a Field Kit.
Validatory Function
We successfully concluded our Naturalist Training Program at the SGNP Mulund Office, with Mr. Narendra Muthe, RFO-Mulund Range, Sanjay Gandhi National Park, as our esteemed chief guest for the valedictory function. He graciously presented certificates and field kits to our budding naturalists, acknowledging their hard work and dedication.
