A new Colorado State University study of the interior U.S. West has found that tree ranges are generally contracting in response to climate change but not expanding into cooler, wetter climates – suggesting that forests are not regenerating fast enough to keep pace with climate change, wildfire, insects and disease. As the climate becomes too warm for trees in certain places, tree ranges have been expected to shift toward more ideal conditions. The study analyzed national forest inventory data for more than 25,000 plots in the U.S. West, excluding coastal states, and found that trees were not regenerating in the hottest portions of their ranges – an expected outcome. More surprising to the researchers was that most of the 15 common tree species studied were not gaining any ground in areas where conditions were more favourable, indicating that most tree species likely will not be able to move to more accommodating climates without assistance.

LINCOLN, Nebraska — The Arbor Day Foundation is investing in technology to help trees grow faster. This investment aims to draw millions of tons of CO2 out of the atmosphere over the next decade, while restoring microbial biodiversity to thousands of acres of forests. Arbor Day’s Impact Fund … is supporting Funga PBC. The startup utilizes DNA sequencing and advanced data analysis to identify growth-promoting, native fungal communities that used to be present and have been degraded over time by land management practices and other factors. Funga then inoculates seedlings with these fungal communities at the nursery, so that these fungi will be established on the tree’s roots at the time of planting. Early results have shown that Funga’s inoculants can increase survival rates and boost tree growth by an average of 30%. This process not only restores and protects belowground biodiversity, but it also enables forests to pull more carbon out of the atmosphere.

The Trump administration has halted funding for federal programs to reduce wildfire risk in western U.S. states and has frozen hiring of seasonal firefighters as part of broad cuts to government spending, according to organizations impacted by the moves. The reduction in resources for wildfire prevention after devastating blazes in Los Angeles …with some expecting losses as high as $35 billion. The Oregon-based non-profit Lomakatsi Restoration Project said its contracts with the federal agencies, including the U.S. Forest Service and Bureau of Land Management to reduce hazardous fuels in Oregon, California and Idaho, have been frozen. …The American Loggers Council, a logging industry group, said the funding freeze has also stopped work under the $20 million Hazardous Fuels Transportation Assistance program, which pays for removing dead wood from forests …calling on the administration to exempt forest management programs from the suspension in federal funding.
