The proposed telescope facility would be located within the western portion of the area known as the Northern Plateau. During construction, support activities would occur within the existing Batch Plant Staging Area and at a Construction Staging Area within or near the Hale Pōhaku Mid-Elevation Support Facilities. Sampling of the flora and arthropod fauna in the proposed use areas was conducted September 25 through October 8, 2008. A second visit occurred February 23 – 25, 2009 to evaluate options at the Hale Pōhaku Support Facility. A third visit occurred April 17 – 23, 2009 to sample for Wēkiu bugs in Area E, the Batch Plant Staging Area, and along the three options for the Access Way, and to sample for vegetation and arthropods at the Hale Pōhaku Support Facility. During the September 2008 sampling, forty-five live-traps were deployed in Area E, along the 4-wheel drive
