Global Research Identifies Endangered Forests Assignment Point Researchers assess the risk of climate change to forests along three dimensions: carbon storage, biodiversity, and forest loss due to disturbances such as fire or drought. the findings show that forests in some areas face clear and consistent threats. Our global analysis renders three important findings: (1) mountain forest loss has accelerated significantly throughout most of the first 2 decades of the 21st century, encroaching on areas of known high conservation value to terrestrial biodiversity; (2) various types of shifting cultivation emerges as the most frequent driver of mountain.
Global Research Identifies Endangered Forests Assignment Point The iucn red list categories and criteria are intended to be an easily and widely understood system for classifying species at high risk of global extinction. it divides species into nine categories: not evaluated , data deficient , least concern , near threatened , vulnerable , endangered , critically endangered , extinct in the wild and extinct . This study presents a global analysis of forest cover and forest protection. an updated global forest map (using modis2005) provided a current assessment of forest cover within 20 natural forest types. this map was overlaid onto wwf realms and ecoregions to gain additional biogeographic information on forest distribution. We show that disturbed and human managed forests dominate the distributional ranges of most forest associated species. species considered as non threatened had on average larger amounts of non managed forests within their range. a greater amount of planted forests did not decrease the probability of species being threatened by extinction. Here we link modelled biodiversity values to remotely sensed data on tree cover to develop global maps of forest biodiversity significance (based on the rarity weighted richness of forest mammal, bird, amphibian and conifer species) and forest biodiversity intactness (based on the modelled relationship between anthropogenic pressures and communi.

Global primary forest decreased by 2.5% (10% in the tropics) from 1990 to 2015. 98% of primary forest occurred in 25 countries, with half in developed countries. additional investment may be needed to improve primary forest area data quality. formally protected forest areas increased more than 50% from 1990 to 2015. In a study published in science william anderegg, inaugural director of the university of utah's wilkes center for climate science and policy, and colleagues quantify the risk to forests from. This report identifies 11 regions that will account for more than 80 percent of projected deforestation between 2010 and 2030. if nothing is done, we could lost up to 656,000 square miles of forests (an area more than twice the size of texas). Global forest loss in 2022 was 6.6 million hectares, an area about the size of ireland. that’s 21% more than the amount that would keep us on track to meet the target of zero deforestation by.
