# Colombian wetland and river ecosystem conservation > Live situation record from CLSTR: https://clstr.news/situations/colombian-wetland-and-river-ecosystem-conservation > Updated: 2026-09-11T19:11:54.000Z. Sources: 6. Developments: 2. Environmental efforts in Colombia are increasingly focusing on the restoration of wetland and river ecosystems through both technical interventions and community-led initiatives. In Cartagena, the Ciénaga de la Virgen has experienced significant shrinkage due to human activities such as land reclamation and mangrove removal. In response, restoration efforts are being directed toward various regions, including the manual removal of aquatic vegetation in the Ciénaga de Cerro de San Antonio to improve hydraulic flow for fishing communities. Community involvement has expanded to include the planting of native tree species to protect the Guáitara River basin from wastewater contamination in Nariño. Additionally, cultural initiatives in Tolima are working to safeguard ancestral knowledge and traditional practices related to the conservation of major waterways, including the Magdalena River. ## Timeline ### 2026-09-11: Colombia communities focus on water conservation and cultural heritage Colombian communities are advancing water conservation through environmental restoration of the Guáitara River and cultural gatherings in Tolima to protect ancestral knowledge and river ecosystems. 3 sources. https://clstr.news/cluster/colombia-communities-focus-on-water-conservation-and-cultural-heritage ### 2026-08-24: Colombia wetland ecosystems face environmental pressure and restoration efforts Colombia faces diverse wetland challenges, from shrinking water surfaces and illegal occupation in Cartagena's Ciénaga de la Virgen to active hydraulic restoration efforts in the Ciénaga de Cerro de San Antonio 3 sources. https://clstr.news/cluster/colombia-wetland-ecosystems-face-environmental-pressure-and-restoration-efforts --- Cite as: Colombian wetland and river ecosystem conservation.
