A new study from the University of Arizona researchers shows that Ponderosa forests are struggling to survive through the Southwest megadrought. And as this drought continues, monsoons play a key role in keeping these forests alive.
As temperatures increase and prolonged drought continues, a new study of ponderosa pine forests underscores the importance of summer monsoons.
The ponderosa pine is one of the most ubiquitous conifer species in western North America. In the American Southwest, winter snowmelt and summer rains play a critical role in ponderosa forests' survival, but the 23-year megadrought may have these semi-arid trees at the end of their rope, according to new research by UArizona scientists.
