Ed, ENTS,
Ed, I've noticed you have been compiling RGI's on most of
your field trips
lately. This is my busy time of year and I have had little time
to get out
in the woods so I've been going over some of my numbers and
Valley Forge
National Park, Pa., has an awesome RGI. If I use trees that
Scott Wade and
I have measured VFNP has a RGI of 14.5. When I listed the VFNP
report I
only listed the tallest tree for each species because the list
was so long.
Here are the numbers.
