In a collaborative project involving
the University of Hawai'i, the Hawai'i Department of Agriculture,
USDA’s Wildlife Services Division, the Hawai'i Department
of Land and Natural Resources, the County of Hawaii, and the
Hawaii Community Correctional Center, a small portion of Lava
Tree State park was cleared of non-native plants and exotic
weeds to reduce habitat for coqui frogs. Non-native plants
cleared from the park included impatiens, philodendron, strawberry
guava (Psidium cattleianum), and Koster’s curse
(Clidemia hirta). Fallen albizia trees (Molucca
albizia) were cut into smaller logs and chipped for mulch.
The cleared area was sprayed with 16% citric acid. The plot
represents a small percentage of the park, and its location
was selected so that clearing it would not have the impact
of causing the coqui frogs to flee to outlying residential
areas.
In the next phase of the cleanup, Nanawale Community Association
and the nonprofit environmental group Malama O Puna will organize
replanting the area with native plants, such as kopiko
ula (Psychotria hawaiiensis), papala
keapu (Pisonia spp.), kolea
lau nui (Myrsine lessertiana),
a'ali'i (Dodonaea sandwichensis), koki'o
ke'oke'o (Hibiscus arnottianus), pukiawe
(Leptecophylla tameiameia), and lama
(Diospyros sandwichensis). Pictures of these native
plants are available online at the University
of Hawaii Botany Department’s Hawaiian Alien Plant Studies
