A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.

For a long time, tropical forests have acted as a carbon sink, taking more carbon out of the air than they release into it, a process that has moderated the impact of climate change. But new research found that in 2015 -- 2016, when an El Niño climate event resulted in drought and the hottest temperatures ever recorded, South American forests were unable to function as a carbon sink.

Over 60 million carbon credits came from projects that barely reduced deforestation, if at all. Of a potential 89 million credits from these offset schemes, only 5.4 million (6%) were linked to additional carbon reductions through preserved forest.

That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.

A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area.

The model can simulate the consequences of extinguishing all wildfires regardless of size, which was done for much of the 20th century and has contributed to a rise in large and severe wildfires, or of allowing certain fires to return to uninhabited areas to help create a more 'patchwork' forest structure that can help lessen fire severity. REBURN can also simulate conditions where more benign forest landscape dynamics have fully recovered in an area.

These cloud-to-ground strikes during little to no rainfall were previously thought to pose wildfire danger only if occurring with less than 2.5 mm of rain in a day (about 0.10 inches). A new study of lightning-ignited wildfires in the U.S. West found the strikes caused wildfires despite up to 7.7 mm (about 0.3 inches) of precipitation. While still a low amount of rain, the more accurate estimation could help responders detect fires earlier, especially those known as 'holdovers,' which can smolder for many days before exploding into full-blown wildfires.

While it's widely thought that loss of forest cover is strongly linked to increased flooding, most studies have suggested that the impact is limited to smaller floods. But the study, focused on two snow-dominated regions in British Columbia, the Deadman River and Joe Ross Creek watersheds, argues otherwise.

How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention.

Nine months afterward, researchers found that while 89% percent of trees located in nine previously documented forest stands were damaged, but only 10 percent had immediately died. The most common damage was stem snapping and major branch damage. The damage with the highest rates of mortality were uprooting and being crushed by a neighboring tree. Large individual trees and species with lower wood density were susceptible to snapping, uprooting and mortality. Those on steeper slopes were more prone to being crushed by neighboring trees.

In a new study, researchers found that the regions most at risk to lose forest carbon through fire, climate stress or insect damage are those regions where many forest carbon offset projects have been set up. The authors assert that there's an urgent need to update these carbon offsets protocols and policies.

This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.

Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.

In the scorching summer of 2022, Europe experienced more trees turning brown than ever, with 37% of temperate and Mediterranean forest regions affected. In the three-year meteorological history of low-?greenness events, characteristic weather signals can be found as precursors of the events.
