Integrating Nature-Based Solutions in Urban Landscapes: Ecological Restoration and Biodiversity Enhancement in the Cubujuquí Interurban Biological Corridor

Through collaboration with local governments and communities in the Cubujuquí Interurban Biological Corridor, FIFCO is implementing a nature-based solution project that aims to demonstrate the possibility of maintaining a healthy and conserved ecosystem while simultaneously supporting urban activities such as industry, commerce, and residential living. The initiative seeks to enhance urban biodiversity while remaining committed to urban ecosystems and corporate stewardship in Costa Rica. Tailored methodologies have been employed to monitor arthropods, amphibians, reptiles, birds, bats, and terrestrial mammals. Documenting existing fauna on-site will guide the subsequent ecological restoration process, expected to improve habitat quality and promote species return. Baseline results identified 163 species across five faunal groups, mainly composed of pollution-resilient species. However, indicator species of more conserved environments were found in green areas near water bodies. Biodiversity index calculations showed low diversity levels, except for birds. Expected restoration actions over 10 years—including natural pool installation, control of domestic animals and pests, artificial warm lighting, removal of invasive species, and planting of native vegetation across 10 ha—are projected to increase fauna richness and abundance by 10–60% and reduce dominance of generalist species. The project aims to transform the company’s green areas into functional spaces that support current fauna and their flora associations for feeding, shelter, and reproduction. Restoration methods will use native species aligned with the Holdridge Life Zone Classification, simulating natural stratification processes while adapting to the urban context. These approaches aim to enhance pollination, water regulation, and ecological connectivity, allowing fauna to use these areas for nutrient cycling and genetic flow. The scenic value is also anticipated to benefit company employees. Restoration efforts may improve water regulation and soil fertility, directly or indirectly benefiting company operations, public image, and access to green subsidies. This innovative initiative seeks to strengthen ecological connectivity and expand multi-sector alliances to build more resilient urban futures, contributing to cost reduction and alignment with international carbon neutrality goals.
