Washington State offers the botanist a true glimpse of the effects of
microclimates on communities of plants. In our local city forest lands (~
700 hectares), there are at least 6 distinct communities that I have
noticed. Within a radius of 40 miles, I have semi-arid <30 cm rain/yr
conditions in the San Juans where one can find cactus species, to >250 cm
rain/yr with forests predominated by maple, hemlock and cedar.
Local topography can have a significant effect on the local climate,
although the regional climate may be *on average* significantly different.
I can't comment on the Hell Creek floras at all, but thought this might be
Oh, and in keeping with the mission of this list, Washington State has no
known dinosaur (yet)
