4) Introduce leaf spot fungus into new locations where it is likely to spread. Introduce the fungus into previously treated areas to help control newly emerging seedlings and saplings, hopefully increasing time between re-treatments. Measure is number of new introductions [Timeline: ongoing, present through June 30, 2000]
The leaf spot fungus released by Eloise Killgore of Hawaii Dept. of Agriculture is present and showing effects on the leaves of miconia. Some plants that were not part of the intended release were also infected, which is evidence that it is moving on it's own. Eloise cultured a sample from the newly affected plants that appears to be stronger and more quickly established than the original. This was applied to gulches accessible by bridges, where conditions are optimal.
There are no areas remaining in Hawaii county that have dense stands of mature miconia trees outside of South Hilo district, which is best for fungus establishment. The field team suggests application of the fungus at sites where seedling densities are high to see if it will have an impact there as well. Some of the sites outside Onomea that are expected to produce thousands of seedlings annually are:
q 11 – Honolii, South Hilo
q 64 – Kupono, Leilani Estates, Puna
q 37 – Kahaopea, Hilo Town Core Population
q 17 – Kurtistown, Puna
There are also some smaller but also notable sites that might be worth exploring as application sites. These are:
q 47 – Aweoweo, Hawaiian Beaches, Puna
q 33 – Reeds Island, Reeds Bay, South Hilo
q 19 – Enos Lane, Mt. View, Puna
q 59 – Hilo Landfill, Hawaiian Home Lands, Hilo
2. IMPLEMENTATION OF EVALUATION AND MONITORING ACTIVITIES.
Activities & Timelines:
1) Monitor the progress of treatment of new and remote populations. Unit of measure is acres monitored [Timeline: ongoing, present through June 30, 2000]
Treatment at new and remote sites was effective, as only two plants were
found during monitoring. The following table includes a list of all
new or remote sites previously surveyed and treated, and monitored during
this grant period.
