And if you will forgive me Bill, but perhaps one way of dealing with the invasive arrow bamboo, Pseudosasa japonica, would be to perhaps = introduce one of it=92s feared enemies, the Giant Panda (apparently arrow bamboo = is favored by both Mei Xiang and Tian Tian here in DC) and as it has been documented that pandas in the wild are known to feed on 42 species of = bamboo [Taylor AH, Qin Z. 1993. Ageing Bamboo Culms to Assess Bamboo Population Dynamics in Panda Habitat. Env Cons 20:76-79], other problem species may also suffer the same fate. Although we will all have heard of the = trouble we can get into when we introduce the alien predator to the alien target species and find that they end up targeting everything native as well = (the concept of =93alternative prey abundance=94 supporting predators came a = little too late for some); and what of that American Dream, KFN: Kentucky Fried Nutria, =93a 12-pound water rat that culinary experts say tastes = somewhat like a beaver, is less greasy than a 'coon but is not quite as good as = possum?=94 [Grimes, D. Sarasota Herald-Tribune, 1997]
