I'm wondering if the County has a strategy to manage the invasive plant species in Trexler.
Has it come up at meetings?
It was my musing of choice while clearing broken Autumn Olive from the trails earlier this month.
My fiancee sent me these links today -

(good powerpoint pres.)
There might be something to learn here. There are some strong correlations and some distinct differences between rhodies and autumn olive. Thorns being the one that sticks out for me. 
At any rate, I know I'm more interested in this than most but, I figure if we're going to alter the landscape with trails we ought to improve the big picture where we can.
Food for thought friends. Ride on.
