FACTORS CONTROLLING THE DISTRIBUTION OF EXOTIC PLANTS IN THE KO'OLAU MOUNTAINS, O'AHU Grant Gerrish Department of Botany University of Hawaii at Manoa Honolulu, Hawaii 96822 A study of native and exotic plants was conducted in two rain forest communities in the Ko'olau Mountains, O'ahu. One study area is on Mt. Tantalus in the southern Ko'olau's; the other, 24 miles to the north, is at Pupukea. The study areas are between approximately 1500 and 2000 feet in elevation and are within the 'Ohi'a Vegetation Zone as described by Egler (1939). Eighteen 400 mz plots were sampled in the more natural vegetation of Tantalus, 16 such plots were placed at Pupukea. All species of vascular plants growing in the sample plots were recorded and their abundance estimated. Of the 110 species of vascular plants found in the sample plots of either study area, 38 are exotic. Of these 38 exotic species, only a few are important in determining the structure and appearance of the vegetation. If frequent is taken to mean "occurring in at least half of the sample plots of one or the other study area," and abundant to mean "having cover greater than twenty percent in at least one sample plot," then only seven species of exotics are both frequent and abundant in these study areas. These seven are the trees: Psidium guajava, P. cattleianum, and Citharexylem spinosum; the smaller woody -: Cordyline terminalis and - Clidemia hirta; and the two grasses: Andro o on vir inicus and setaria palmaefolia. These species i r respective vegetation layers and locally give the vegetation the appearance of being dominated plants. by exotic Concern about the impact of exotic plants on Hawaiian ecosystems and the detrimental effects that these introductions may have on the endemic flora necessitates the examination of the ecology and behavior of exotic species and to ask the question "Why of the more than 4000 species of exotic plants found in Hawaii (St. John 1973) have these seven species become frequent and abundant in these rain forest communities?" Svecies which are obviously "trailside weeds," such as Erechtites hieracifolia, w i l l not be discussed in detail, since any damage to the native vegetation associated with the presence of these plants can be more directly attributed to the disturbance that allowed them to become established. At the same time, it is not realistic to discuss these ecosystems under conditions of no human-induced disturbance. The presence of pigs and goats in the southern Ko'olau's, and at least occasional human presence throughout the
