Impact of Ecological Restoration on Biodiversity Conservation: A Systematic Literature Review

Abstract

Ecological restoration is a key strategy to reverse biodiversity loss and mitigate the impacts of environmental degradation, especially in Neotropical regions. This study reviews 29 recent investigations on restoration techniques and their implications for biodiversity conservation. The most effective strategies include applied nucleation, reforestation with native species, and understory light management, complemented by technologies such as drones and image analysis for monitoring. While active restoration accelerates ecosystem recovery, it faces high initial costs. Though more cost-effective, passive restoration proves less efficient in severely degraded areas. Innovative models, such as using Amazonian dark earth and agroforestry systems, have demonstrated dual ecological and economic benefits by fostering community participation and attracting private investments. Restored ecosystem services include pollination, water regulation, and carbon sequestration. However, challenges like lack of funding, limited training, and technical barriers restrict large-scale implementation. Climate change adds complexity by affecting the resilience of restored ecosystems. This analysis underscores the importance of robust public policies, financial incentives, and multisectoral collaboration to ensure the sustainability of these initiatives. In conclusion, ecological restoration is a comprehensive tool to address environmental and socioeconomic challenges, with a significant positive impact on biodiversity and ecosystem services. Innovation and an adaptive approach are needed to maximize its benefits.
