To date, the majority of studies examining bark beetle outbreaks and subsequent fire severity in the U.S. Rocky Mountains have focused on outbreaks of mountain pine beetle (MPB; Dendroctonus ponderosae ) in lodgepole pine ( Pinus contorta ) forests, but few studies, particularly field studies, ...
Gardeners understand the importance of caring for Mother Nature, so if they can be eco-friendly by reusing something, they are all over it. Arusted patio fire pitcan be restored or used as storage. Evena used swimming poolcan be turned into an upcycled project. In doing so, you get to ...
