Devil weed (Chromolaena odorata): The crew surveyed 1,120 acres by ground removing 91 mature and 1,562 immature plants. In addition, after several cancellations due to bad weather, OISC was finally able to conduct an aerial treatment of an isolated devil weed infestation in Kahana Valley. Many, many thanks to the Hawaiʿi State Division of Parks for their patience and flexibility.
Cape ivy (Delairea odorata): 52 immature plants removed from Kaloʿi Watershed.
Himalayan blackberry (Rubus discolor): 11 acres surveyed and 15 plants removed from the Pālolo Watershed.
Coqui frog (Eleutherodactylus coqui): Worked with HDOA to conduct sprays at 2 sites where there were more coqui frogs than could be hand captured. Both sites are now quiet but monitoring will continue. If you think you hear a coqui frog please report it to OISC at email@example.com or 808-266-7994. If possible, please record what you are hearing and e-mail it to us.
Cane ti (Tibouchina herbacea): The crew conducted surveys in ʿAiea in response to 2 immature plants found by OISC partners in that watershed and in Poamoho where the main infestation occurs. No Tibouchina was found in ʿAiea, but the crew found another hotspot that they could not reach on foot in Poamoho. Eleven mature plants and 169 immature plants were removed from the core in Poamoho.
Regular early detection surveys for little fire ant, coconut rhinoceros beetle and naio thrips found none.
