TORONTO — World Wildlife Fund Canada’s Living Planet Report Canada (LPRC) 2025: Wildlife at Home reveals the most severe average decline in the size of monitored wildlife populations in Canada since WWF-Canada began reporting two decades ago. Using the largest dataset to date, the report presents the clearest — and starkest— picture of wildlife loss in Canada yet. More than half (52%) of the species studied are decreasing in abundance. On average, every species group included is trending in the wrong direction. LPRC 2025 comes at a time when governments across Canada are prioritizing rapid development, while loosening regulations that protect nature and species at risk. …The biggest declines were seen in grassland habitats, where wildlife populations declined by 62% on average since 1970. In forests, mammal populations declined by 42%, over the last five decades. Species of concern, those found on the IUCN Red List of Threatened Species, saw their populations decline by 43%.
