For much of the past decade, the National Park of American Samoa has devoted considerable effort to eradicating invasive tamiligi trees (Falcataria moluccana) with a field team affectionately known as the “Tamiligi Slayers.” All too often, management efforts like these yield mixed results. Not this time !
A joint NPS and USDA Forest Service study led by Dr. F. Hughes, reports a successful tamiligi removal project where the affected native forests recovered splendidly. Once tamiligi (a.k.a. albizia) is removed, native tree species take advantage of increased tamiligi-converted nitrogen in the soil and access to sunlight. Moreover, after 3 years, tamiligi seedlings stopped re-emerging from the young native
forests. The tamiligi at the National Park of American Samoa appear to be successfully slain.
