· Continued gathering of distribution data for Miconia though ground survey. Add new information to GIS map including, areas surveyed, areas treated, plant locations, and GPS points when available. Add all details to computerized database.
The miconia distribution database in GIS format is updated weekly with information collected daily by field teams equipped with GPS receivers. Surveys, treatments and monitoring activities, along with hotline tips and other reports are also collected and used to track miconia locations and control progress. A summary of the status (confirmed-y, potential-i, excluded-n) of each new management unit or site can be seen in Attachment 1. Site centers list & status.
· Maintain database and precise maps gained through GPS and transferred
to GIS to provide insights into the patterns, time scale, and likely conditions
of Miconia spread. This is essential to (1) direct searches to specific
areas by field crews (2) prioritize control efforts; and, (3) relocate treated
areas for monitoring and re-treatment.
The area of potential infestation is large, island-wide over 20,000 acres.
With the help of birds, each mature tree site that produced seeds even once
has potentially affected about 800 acres. Most seedlings will emerge
near the mother plant, but in some cases seedlings have been found a kilometer
or more from the nearest known tree. Since there are a handful of these
examples in Hawaii County, a ground search of a kilometer in all directions
from a mature tree is not unreasonable if the goal is 100% control at the
edges. At the extreme edges of the infestation near forests, it is
urgent. Air surveys in 100 meter wide
