So, seeing this for what it was, I collected the tags I could find, measured the basal diameter of the plants who still had tags attached to them (hey, after all, that's a years worth of growth in basal diameter I could measure there, even if I couldn't say much about height), and left with the plan to come back in 2012 and see what happens. You see, buckthorn is notoriously tenacious - it re-sprouts quite readily. The most affective way to manage buckthorn is to cut it and immediately apply a weed killer (this is based on research reported in several papers, many from the Natural Areas Journal). I had a suspicion I would come back in a year and see plenty of re-growth. Of the 147 plants originally tagged, I was able to leave 44 and recover 45. That left 58 unaccounted for. Given how high the flood waters came from the two large storms that hit this area in 2011, I suspect that many of them are in the Ellis River or along its banks. This season I returned to Winn Falls and was tacken aback by the amount of re-growth.
