additional site. Since there is no information concerning either species before recent time, the range and status of these species are discussed in the section below, “Current Range and Population Status.” CURRENT RANGE AND POPULATION STATUS Maps or descriptions of the exact locations of known sites will not be included in this Plan due to the possibility that vandalization or unauthorized collection could be encouraged by the public relBase of this information. The seven sites on which these two species occur will be referred to as Sites #1-7 in this plan (Table 1). The Service will maintain the figures listed as Appendix B in its files, and will consider requests for these figures on a case-by-case basis. Table 1. Presence of Isodendrion South Kohala. Parker Ranch Hawaiian Home Lands Site # 1 2 3 4 hosakae and LiDochaeta venosa in Isodendrion hos akae X X X LiDochaeta venosa 5 X 6 X 7 Isodendrion hosakae and Lioochaeta venosa are localized and rare. They occur in the Waikoloa region of the South Kohala District on the island of Hawaii. Both species occur together at two sites, 6 X X X x
and I. hosakae and ~. venosa occur separately at one and four other sites, respectively. The two species occur together at Sites #1 and 2. Isodendrion hosakae occurs alone at Site #3 and Livochaeta venosa occurs alone at Sites #4-7. All of these confirmed occurrences are between 770 and 1097 meters (2500 and 3600 feet) elevation. It is inferred that their ranges once included, at the least, the lands between the cones where they are now extant; however, there is no way to know what their ranges and population densities might have been historically. Range of Lioochaeta venosa There are six populations of Litochaeta venosa. At four of these sites, present and historical occurrence of L. venosa is well documented near the 860 meter (2800 foot) contour in Waikoloa, South Kohala District, island of Hawaii. L. venosa was first collected by Rock in 1910 in the crater of Site #1 and in 1938 by Hosaka at Site #4 (Herbst 1979). As of 1982, sizable populations had been found at both of these sites and at Sites #2 and 5 (Cuddihy ~ j~. 1983). The 1980-1982 survey of 12 cinder cones and several gulches in the Waikoloa ahupuaa of South Kohala found L. venosa at all four sites named above (Cuddihy et ~j. 1983). This survey included the vicinity of Site #6 but did not record the population of ~. y~~j subsequently found and reported near there under the synonyms of L. ~innatifidaand J~. setosa (St. John 1984; see Taxonomy section). The most recently discovered population of j~. venosa occurs at Site #7. These plants were discovered in June 1993, by a representative of the U.S. Soil Conservation Service while developing a soil conservation plan for Hawaiian Home Lands (J. Giffin, pers. comm. 1993), and identified as L. venosa in October 1993 (D. Herbst, U.S. Army Corps of Engineers, pers. comm. 1993). 7
