Book Description
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.

Book Description
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.

Book Description
This is the first text/reference on growing exotic forests, bringing together information that heretofore was widely scattered throughout the journal literature, and is the only work to cover both tropical and temperate climes in one volume. Exotic means not native to the region - now, exotic forestry is spreading incredibly rapidly. This volume covers basic concepts, widely illustrated with examples from all over the world, based on the authors' extensive experience in the field. Written in a straightforward manner, the text is understandable to both the professional and the layman. Topics covered include genetic improvement of exotics - developing and using land races - genotype X environment interaction, limitation to production in and unusual problems with exotic forests, gene conservation and exotic forestry, and much more.
