Plant Threat Level:   Hibiscus brackenridgei, the state flower
of Hawaii, is an endangered plant endemic to the Hawaiian
islands. Unfortunately, there are less than 60 plants in eight
populations on the islands of Lanai, Maui, and Hawaii, which are
protected by the Endangered Species Act. Threats that include
development, overgrazing by livestock and feral animals, as well
as competition from invasive weeds have contributed to the
drastic reduction in wild populations. Measures being taken by
conservationists and botanic gardens to protect the few
remaining populations of Hibiscus brackenridgei include weed
control, fencing to exclude animals, preservation of remaining
intact habitat and conservation of plants and seeds in botanical
gardens and seed banks.
