1. Purpose and Scope This standard operating procedure (SOP) is designed to assist with plant identification, invasive plant threat prioritization, and the collection and processing of vegetation on Maunakea for both field staff and with public outreach activities. The identification guide portion of this SOP is not intended to be comprehensive, rather it is representative of common species to facilitate identification. This SOP should be used under the guidance of a professional botanist if complete confidence in specimen identification is required.

2. University Management Area and Ecological Zones The Office of Maunakea Management (OMKM) manages the Mauna Kea Science Reserve (MKSR) including the Astronomy Precinct, Road Corridor, and Halepōhaku (HP) facilities. There are three community types within the UH Management Area; the Alpine Shrubland (from 2,900m/ 9,500ft to 3,400m/11,150ft), Alpine Grassland (3,400m/11,150ft to 3,900m/ 12,800ft), and the Alpine Stone Desert (3,900m/ 12,800ft to the summit).

Priority Plant Threats Plant threats are identified using the Hawai`i Pacific Weed Risk Assessment (HPWRA) score. If no score is available for a species, OMKM has requested an assessment from the HPWRA program and in the meantime will continue to monitor the distribution of the species. The Maunakea Invasive Species Management Plan identifies a Weed Risk Assessment threshold score of 8 or higher for evaluation and potential action, and a score of 17 or higher designated as “high” priority species.

Monitoring and control procedures will be developed for all introduced plant species currently established in the Management Area (plants listed below). The complexity, level of involvement by oversight committees, and resources allocated to each introduced species will be determined by the level of threat (biological, cultural, and aesthetic) they pose. Many species will see nominal control efforts, given their widespread presence on the island and threat level. A response plan should be prepared for each high priority species on UH managed lands. High priority species are shown in bold.

Species are grouped by management area and sorted by family, genus, and species. The common name and morphology are also displayed, and HPWRA score provided if available.

6. Vegetation Collection, Processing & Identification Vegetation will need to be identified, and in some cases photographed or collected to confirm identification. See below. 6.1. Priority Plant Threats Established within UH Management Area If the plant species is established within the management area and is a high priority plant threat, refer to the Response Plan4 for that particular species. All introduced species within the MKSR are to be recorded and pulled if confident in identification. If you think the species may not have been previously documented as established within the UH management area, see section immediately below. When pulling the introduced species, pull the entire root to prevent re-sprouting. Once pulled, place the introduced species in a sealed bag to prevent further dispersal. Dispose the bag of pulled weeds in a rubbish bin.

Established on Adjacent lands or on Island Any non-native vegetation not documented as established within the UH Management Area, but observed or possibly observed on UH lands shall be recorded with a GPS point and a photo. You may also collect a sample (of a branch, flower, seed head, leaves, etc.), but you must be sure that you have a Ziploc bag or sealed container to prevent dispersal into your personal belongings and the environment. Take as many notes as possible about the area the species was found and the maturity and quantities of individuals.

Collected vegetation samples can go in the refrigerator until they can be identified. Potential vegetation threats must be identified within 1 week of observation and reported to the OMKM Natural Resource Program Manager (NRPM) within 24 hours. Vegetation can be identified using this SOP, books, and other resources. Photos and descriptions can also be sent to a State botanist, or the Big Island Invasive Species Committee (BIISC) for identification confirmation. The Natural Resource Program Manager will decide whether to involve the Emergency Response Management Committee. See Section 5. Rapid Response in the Maunakea Invasive Species Management Plan. 6.2. Native Vegetation Species Native species are not collected, but rather recorded. Do not pull individuals that could be a native.

Identification Known If the species is endangered (i.e. Maunakea Silversword), and tags are not observed near the base of the individual, take a few photos and a GPS point. New endangered species locations should be reported to the Hawai‘i Island Division of Forestry and Wildlife staff. Species that are known and can be confidently identified as native should be recorded in the field notebook or on the associated datasheet.

Identification Unknown If not confident in identification, try to determine nativity using this SOP. If still unconfident in nativity take a photo, and record its location with a GPS point. Collecting samples that could possibly be native are highly discouraged (the species could be rare). If confident that vegetation species is introduced and established within the UH management area, see Established within UH Management Area section above. If confident the species is established on adjacent lands see Established on Adjacent lands or on

4 Response plans for each individual species established within the UH Management area are currently being developed.
