Study links protecting Indigenous peoples' lands to greater nonhuman primate biodiversity

"By comparing geographic patterns of nonhuman primate biodiversity and human land-use, researchers discovered that areas managed or controlled by Indigenous peoples tend to have significantly more primate biodiversity than nearby regions. They also found that lorises, tarsiers, monkeys and apes whose territories overlap with Indigenous areas are less likely to be classified as vulnerable, threatened or endangered than those living fully outside Indigenous lands." [2] "Given that the ranges of 71% of primate species intersect Indigenous Peoples’ lands, we will only avert the mass extinction of primates if we respect and support biocultural diversity and the efforts of Indigenous Peoples to maintain their languages, and cultural and symbolic ties to their lands and waters."

Fastest deforestation of Amazon rainforest in Brazil in six years; Amazon reaching a resilience tipping-point

"Deforestation of the Amazon rainforest in Brazil has hit a six-year high, the national space agency, Inpe, reports. Some 3,988 square kilometres (1,540 square miles) of land were cleared in the region between January and June. Last year, 3,088 square kilometres of the rainforest were destroyed during the same period." [1] "We find that more than three-quarters of the Amazon rainforest has been losing resilience since the early 2000s, consistent with the approach to a critical transition. Resilience is being lost faster in regions with less rainfall and in parts of the rainforest that are closer to human activity. We provide direct empirical evidence that the Amazon rainforest is losing resilience, risking dieback with profound implications for biodiversity, carbon storage and climate change at a global scale."

Facing Extinction: Nine Steps to Save Biodiversity

"More than 140 species of mammals, 24 birds, 6 reptiles, and 5 amphibians deteriorated in conservation status, moving from lower to higher risk categories of concern on the IUCN Red List of Threatened Species, the global authority on the conservation status of the world’s animals and plants. Only 37 mammals improved during this period, along with two birds and one amphibian. Here are nine tactics that could help moderate human-caused extinctions: 1. Biodiversity Parks 2. Ecologically Reclaimed and Restored Habitats 3. The Fabric of Local Communities 4. Diversity in Human Landscapes 5. Legislation 6. Ecological Economics 7. Endowment: Biodiversity Trusts 8. Bioliteracy 9. Toward Zero Extinction"

High exposure of global tree diversity to human pressure

"83% of tree species experience nonnegligible human pressure across their range on average. ... Protecting high-priority areas for the top 17% and 50% priority thresholds would increase the average protected proportion of each tree species’ range to 65.5% and 82.6%, respectively, leaving many fewer species (2,151 and 2,010) completely unprotected. The priority areas identified for trees match well to the Global 200 Ecoregions framework, revealing that priority areas for trees would in large part also optimize protection for terrestrial biodiversity overall. Based on range estimates for >46,000 tree species, our findings show that a large proportion of tree species receive limited protection by current PAs and are under substantial human pressure. Improved protection of biodiversity overall would also strongly benefit global tree diversity."

Amazon rainforest is approaching a tipping point of transitioning to a savannah

"Deforestation and climate change, via increasing dry-season length and drought frequency, may already have pushed the Amazon close to a critical threshold of rainforest dieback. ... We find that more than three-quarters of the Amazon rainforest has been losing resilience since the early 2000s, consistent with the approach to a critical transition. Resilience is being lost faster in regions with less rainfall and in parts of the rainforest that are closer to human activity."

Conservation of Earth's biodiversity is embedded in Indigenous fire stewardship

"Indigenous peoples comprise 5% of the world population but protect approximately 85% of its biodiversity through stewardship of indigenous-managed lands. ... Supporting indigenous-led fire stewardship can assist with reviving important cultural practices while protecting human communities from increasingly severe wildfires, enhancing biodiversity, and increasing ecosystem heterogeneity."

Wildlife populations have plummeted by two-thirds in 50 years

Natural areas that used to support biodiversity and have been converted for farming are the biggest reason for the population decline of thousands of species around the world. The WWF study has found that the average population size has dropped by 68% worldwide between 1970 and 2016.
