2014: Ongoing Fieldwork

Habitat Restoration

January to mid-March volunteer fieldwork continued on a weekly basis.  Several new native plants were introduced to the Preserve. Volunteers removed several large sea grape trees along the Diamond Head boundary of the upper portion of the Preserve. Five tall invasive ironwood trees were cut down to a height of about five feet, so they can be easily trimmed, or removed, in the future. Falling ironwood needles create a thick mat on the ground, suppressing growth of understory plants that could provide shade or shelter for shearwaters. A narrow, curving path, leading from the Preserve gate to the seaward cliff.  The use of the path prevents many small, fragile native plants from being trampled by habitat restoration volunteers and other visitors to the Preserve. A group of ant specialists visited the Preserve to collect ant species for identification.  They also offered advice to volunteers regarding the prevention of infestations of harmful ant species at the Preserve. Additional artificial nests were constructed in 2014.

 

Volunteer groups included:  Eagle Scout candidate and his troop, a professional group of local engineers, a Botany class from Leeward Community College, and USFWS annual training session attendees.
