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. SOP D, v1.0 8/17/15 Plant Threats, Identification, Collection, & Processing Guide Page 1 of 53 Office of Maunakea Management Invasive Species Plan 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).

Native Plant Species Native species established within the management area are identified below. Species are grouped by management area and sorted by family, genus, and species1. Common name2 and morphology are also displayed. Table 1. Native Species in the Road Corridor & at Halepōhaku (below the MKSR).

Names are subject to change with updated ITIS information. 2 Common names include Hawaiian and English names when known. Hawaiian name spellings confirmed in Nā Puke Wehewehe ‘Ōlelo Hawai‘i.

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
