Three methods of deriving advanced dynamic site equations demonstrated on inland Douglasfir
Vegetation responses to edge environments in old-growth Douglasfir
Western Hemlock zones, often co-dominated by Douglasfir
(Pseudotsuga menziesii) in areas with a history of fire, are also wet (150-300 cm annual precipitation), somewhat cooler (7-10[degrees]C), but with drier summers (6-9% of total precipitation).
In Florida, yellow cedar, western red cedar, eastern white cedar, western larch, and tamarack all showed similar performance, whereas Douglasfir
decayed substantially faster.
