Western Larch

Sunday, October 27th, 2013

_MG_6337_2Western Larch “Larix occidentalis” is our only deciduous conifer.  The needles change color from green to yellow before dropping off, providing bright coloration among the evergreens in the forests east of the Cascades in the fall.  These trees grow to a height of 140 to 180 feet and the bark may be 6 inches thick at ground level.  They are relatively resistant to fire and that tends to make them more common in areas that have been burned over by forest fires.  Photo:  Near Paulina in Central Oregon 20/19/2013
