Regarding alien species which have the potential of becoming bad weeds on Pohnpei (and on tropical high islands in general)
Tim Flynn and I just finished updating our checklist of Pohnpei vascular plants just last week, incorporating observations and collections from our Sept. trip. We came up with a short list of some species alreadly seen growing on Pohnpei which have proven to be particularly bad weeds in Hawaii and elsewhere. Here they are:
lncidentally, there is a group here known as Hawaiian Ecosystems At Risk Working Group (HEARPWG). If you are interested in getting on board their email server, contact Philip Thomas: thomasp@maui.com
Plants seen on the Fall 1999 walk:
Combatting invasive species: Watch for plants that are new to Pohnpei and that spread rapidly. Destroy all plants as soon as it appears it might be aggressive. Wedelia trilobata came to the island as a single plant - how easy it would have been to wipe it out back then. Now it is beyond control. On your own land you can, with a few years of hard work, remove all of it. But the plant will never be gone from the island.
