have been, or soon will be filled by young, fast - growing tree species including quaking aspen <br />and cottonwood. The shrub layer is very thick and similar in composition to AC -U -2, with <br />European and glossy buckthorn common. Likewise, the ground layer is sparse with species <br />common in disturbed woodlands prevalent. Overall, this forest has great potential to improve if <br />actively managed to reduce nonnative shrub levels and reintroduce appropriate processes and <br />species. It represents the best opportunity to manage an upland natural community in Acorn <br />Park. <br />Community <br />Activity <br />Priority <br />Estimated Cost <br />Comments <br />AC -3 <br />Cut Buckthorn <br />High <br />Approximately <br />Cut and treat all stumps with 25 -50% <br />and other <br />$3,000 -8,000 or <br />solution of Roundup or Garlon.
