ENTS,

Yesterday I attended a seminar in Lehigh Co. and stopped by the 72 acre Pool
Wildlife Sanctuary on my way home.  The sanctuary is located in Emmaus,  Pa.
There are many native and non native species that were planted trough out
the site, probably in the 70's.  The first trail I came to was lined with
what I think are Quaking Aspen.  The upper portion of the trees bark is
smooth and creamy white and its base thick and gray.  I have seen this tree
before but not nearly as large as these.  I measured two of them and the
tallest is 8'7" x 100.8'.  I took a leaf sample from the site and will post
a photo of it if anyone can confirm its ID.  This trail then lead me to a
small flat overlooking the Little Lehigh Creek.  This flat, only a couple
acres,  has probably seen little disturbance and has the tallest trees
within the preserve.  Species within the flat are tulip poplar, bitternut &
shagbark hickory, red, white, & chinkapin oak, white ash, american basswood,
black gum, box elder, eastern hophornbeam, flowering dogwood, blackhaw,
redbud, american bladdernut, and american elder.  I also saw some burning
bush but am not sure if it was the native species or not.  My hands and feet
were freezing at this point so I didn't take many measurements.  Does anyone
have any numbers for the bladdernut ?  I saw one that was around 20+ feet.
