Rabbits presumably modified the unknown original vegetation in their 70 or more years on the island and reached an equilibrium with a plant cover composed largely of a few hard y introduced grasses. A total of 28 species of higher plants has been recorded from the island, only 6 of which are native to Hawaii. Rabbits occur in low to moderate numbers, sustained by a food source that is enriched by bird guano and subject to annual drought. Average body weight of the mouse is remarkably heavy at 19.5 g. Data on biological and food habits are presented for both mammals. Among 13 species of ectoparasites of birds and mammals are two unusual host adaptations : of the cat flea, Ctenocephalides felis felis, to Oryctolagns cuniculus, and of the Oriental rat flea, Xenopsylla cheopis, to Mus musculus. Rabbits appear not to be detrimental to the nesting of bird s, and their control or extermination is discouraged at present. The scientific importance of the island's unique ecosystem is stressed, and proposals for its intensive study are outlined.

Root systems of R. tomentosa and M. malabathricum in Kapaa and Halii soils were very shallow, with tap roots turning laterally at shallow depth and with long lateral roots very close to the soil surface. Deeper tap-root penetration of R. tomentosa and M. malabathricum was observed in the Koolau soil. Lime and phosphorus treatments were added to bauxitic subsoils of the Kapaa and Halii series in pots and Leucaena glauca (1.) was planted in the pots. Tap roots of L. glauca were stimulated by phosphorus treatment, but were restricted in untreated subsoils. Increased root development with phosphorus treatment seemed to be more related to phosphorus supply than to decreased aluminum effects. No evidence of root damage due to aluminum was found. L. glauca: roots were sectioned with a freezing microtome and stained, using hematoxylin without a mordant. Although all staining obtained could not be attributed to aluminum, since other metals can act as mordants for hematoxylin, intensity of staining was assumed to be related to aluminum concentration in the tissues. Cell walls, nuclei, and cytoplasm stained in all tissues, and outer walls of epidermal cells stained very heavily. Staining was more intense in roots from check and P-treated plants than in roots from lime-treated plants.

Ongoing research is described and the additional research needed to develop a comprehensive program is identified. Suggestions are offered for meeting these research needs, and the appropriate role of the National Park Service in supporting such research is discussed. Two problems of special concern to the National Park Service are addressed: 1. It is recommended that one or more NPS representatives in Hawaii appointed to the Fish and Wildlife Service recovery team for the Hawaiian Crow, since Hawaii Volcanoes National Park should be involved in the recovery program. 2. It seems unlikely that large-scale propagation projects, involving captive breeding populations with subsequent release of offspring, will play a significant role in the preservation of endangered Hawaiian birds, especially the honeycreeper. Therefore, it is recommended that NPS resources not be used for construction of extensive facilities for captive propagation projects.

Both roots and rhizomes of all three species possess vessel elements. Wide perforations, an expression of pit (perforation) dimorphism within perforation plates, are prominent, more so than in most other fern families. Monomorphic perforations are also common, as are perforations in which weblike or porose pit membranes are present. Habitats of Hymenophyllaceae are characterized by high humidity with little fluctuation. However, fluctuation in moisture availability within the substrates of Hymenophyllaceae may be related to the abundance of vessels and the distinctiveness of the perforation plates. A peculiarity of hymenophyllaceous tracheary elements not hitherto reported in ferns to our knowledge is reported: gaps in the secondary wall pattern at outer surface of cell angles. These gaps take the form of rhomboidal depressions or a continuous depressed strip.

On the 1976 expedition four people trekked down through the valley from June 26 through 29, along the 1967 Expedition route, where possible. There is little evidence of the 1967 expedition remaining in the valley. The trails are difficult to locate and the campsites are recognizable only to those people who were on the expedition. There is no evidence of weeds being introduced into the valley along the 1967 trails. There is serious pig damage in the area between Basecamp 1 and Palikea.
