dc.description.abstract During a 1993-95 survey of Naulu Forest remnants and other kipuka on Holei and Poliokeawe Pali in Hawaii Volcanoes National Park, one proposed endangered and one candidate endangered plant species were found and mapped. Sixteen hala pepe (Pleomele hawaiiensis) were observed; seven were small plants, indicating natural regeneration. Forty-six mature 'ahakea (Bobea timonioides) trees were counted; no seedlings were observed. Seven other rare native tree and shrub species were found in the study area. Only two hame (Antidesma pulvinatum) and one kolomona (Senna gaudichaudii) were found on the eastern side of one kipuka (Area I). This is the only Park site known to support hame and one of few sites with kolomona shrubs. Only three 'ohe (Reynoldsia sandwicensis) were seen in the study area: two on Poliokeawe Pali and one in the western Naulu kipuka (Area 11). This tree has become very rare in the Park because of forest destruction from recent lava flows. Three maua (Xylosma hawaiiense) were observed, one in each of three study area kipuka (Areas I, II, and IV). Hao (Rauvolfia sandwicensis) occurred primarily in the easternmost large kipuka of the study area (Area I), where 26 trees were sighted. One additional hao tree was found in a small grove farther east (Area III). 'Iliahi (Santalum paniculatum) and naio (Myoporum sandwicense) are uncommon species in the Park; both had sizable populations in Naulu Forest, particularly in the Kealakomo kipuka (Area II) on Holei Pali. Density and size class structure of four common native tree species were determined in the two largest Naulu Forest kipuka (Areas I and II). Lama (Diospyros sandwicensis) was the most common tree with densities of 89.3 and 171.3 plants/ha in Areas I and II, respectively. The lama population was composed primarily of mature trees. Alahe'e (Canthium odoratum) and naio (considered a common species in one kipuka) displayed stable population structures with many young plants. A few young mamane (Sophora chrysophylla) occurred at low density in only one kipuka (Area I). Thirty-six alien plant species were observed in the two intensively surveyed kipuka; those with highest cover and frequency along transects were lantana (Lantana camara) three other shrub species, scaly swordfern (Nephrolepis multiflora), and four grass species. Alien grasses pose a threat to rare plants because of their ability to carry fire; lantana and other shrubs may interfere with rare plant reproduction. en_US
