Climate change threatens forest survival on drier, low-elevation sites

Predicted increases in temperature and drought in the coming century may make it more difficult for conifers such as ponderosa pine to regenerate after major forest fires on dry, low-elevation sites, in some cases leading to conversion of forests to grass or shrub lands, a report suggests.  "A decade after this fire, there was almost no tree regeneration at lower, drier sites," said Erich Dodson, a researcher with the Department of Forest Ecosystems and Society.
