Growth and volume data for trees on 25 plots reprsenting 11 introduced species in Hawaii were recorded during a 21-year period. Tree were measured at about 5-year intervals to determine overall growth and stand development. The sites selected were considered better-than-average in terms of elevation, amount of precipitation, and soil quality. Except for redwood, stands were unmanaged. The data reported suggest that 10 tree species can grow fast enough to warrant more extensive plantings for timber or wood fiber production.

In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Common Forest Trees of Hawaii, first published in 1989 as USDA Forest Service Agriculture Handbook 679, is an illustrated reference for identifying the common trees in the forests of Hawaii. Useful information about each species is also compiled, including Hawaiian, English, and scientific names; description; distribution within the islands and beyond; uses of wood and other products; and additional notes. The 152 species described and illustrated by line drawings comprise 60 native species (including 53 that are endemic), 85 species introduced after the arrival of Europeans, and 7 species introduced apparently by the early Hawaiians. One chapter is devoted to forests and forestry in Hawaii. Maps of the Hawaiian Islands show the physical features and place names, major forest types, and forest reserves and conservation districts. Each tree species is illustrated by a full-page line drawing.
