Overview
- Argentine ecotoxicologists at UNL–CONICET report that sediments from repeatedly burned wetlands caused high mortality and severe physiological and behavioral effects in amphibian larvae in lab bioassays, with risks also flagged for fish eggs and larvae.
- The peer-reviewed study, published in the Journal of Environmental Science and Health, Part A, finds that reflooding can mobilize combustion-derived contaminants and salts, leaving a persistent “toxic fingerprint.”
- With large wildfires reported in Patagonia and recent burns at Laguna de Rocha, researchers and local groups in Argentina call out chronic underfunding of fire prevention, post‑fire monitoring and ecological restoration.
- Against decades of wetland losses estimated at about 22% globally, Peru has moved to consolidate protections through Law 32099 and a 2025 regulation establishing inventories, prioritization criteria and monitoring tools.
- Mexico’s CONABIO runs a two‑decade Mangrove Monitoring System that maps change, now adding AI and preparing a 2025 national inventory update; the country hosts about 905,086 hectares of mangroves, roughly 6% of the global total and fourth worldwide.
