BIISC PLANT CONTROL CATEGORIES
Eradicated Species: All known populations eradicated, island-wide
ACTIVE PLANT TARGETS
On-going control with the goal of island-wide eradication
RAPID RESPONSE SPECIES
Detected, Under Evaluation and Rapid Response Treatment: Species detected on roadside surveys are evaluated for rapid response actions based on criteria such as the size of the population, invasive behavior elsewhere, the Hawaii Weed Risk Assessment score, expert interviews, feasibility of control, and landowner participation. Species which meet the criteria move to Active Targets. Mature plants at the detection site may be pre-emptively removed, while the complete evaluation proceeds.
Examples: Moluccan raspberry (Rubus sieboldii), orange and purple cestrum (Cestrum aurantiacum, elegans), Cherokee rose (Rosa laevigata), Dahoon holly (Ilex cassine).
COOPERATIVE PROJECT SPECIES
When the need exists to support land managers, BIISC assists with control on species for which we do not have sufficient resources on our own to tackle, and which can be important to control in a sensitive area. For non-plant species such as coqui and snake sightings, BIISC works with partners to summon the appropriate response.
Examples: gorse (Ulex europaeus), poison devil’s pepper (Rauvolfia vomitoria), red mangrove (Rhizophora mangle), albizia (Falcataria moluccana), miconia (Miconia calvescens), fountain grass (Cenchrus setaceus), Himalayan raspberry (Rubus ellipticus).
OUTREACH SPECIES TARGETS
Education is done for many species that are deemed invasive based on agency lists but not necessarily acted upon by BIISC. Citizens are encouraged not to cultivate invasive species and nurseries not to sell them. Basic concepts of ecology and invasiveness are shared; and the role of climate change in augmenting invasive species.
Examples: little fire ants (LFA, Wasmannia auropunctata), naio thrips (Klambothrips myopori), rat lungworm disease and West Nile Virus.
