The performance of 90 species, mostly from the tropics and subtropics, was appraised in field trials for 5 years. Planting sites ranged from near sea level to 6360 feet (1940 m) elevation; rainfall from less than 20 inches to more than 200 inches (500 to 5000 mm); and soils from thin mucks overlaying lava rock to deep, highly leached latosols. Thirty-two hardwoods and 10 conifers were rated as promising for either timber production, watershed production, erosion control, or amenity plantings. Fourteen are native to Australia, and are eucalypts. Few of the high quality timber species tested proved well adapted, with low soil fertility the primary limiting factor. Very few trees died from disease or insect attack.

Species trials have been conducted in Hawaii since the 1870's. Many species have been successfully established and harvested, whereas native species have failed in numerous reforestation projects. Since the early 1960's silviculture research concentrated on developing methodology for establishing and developing forest stands for timber production.

A two-stage shelterwood cutting, at 12 trees per acre, with site preparation, enhanced seedfall, regeneration, and residual growth at the Challenge Experimental Forest, north central California. Shelterwood trees produced 9.2 times more seed than trees in the control. Ponderosa pine regeneration numbered about 3700 seedlings per acre (9139 per ha) and tolerant conifers 600 seedlings (1482 per ha) after 5 years. Hardwood seedlings and sprouts also were abundant. Basal area growth rates for all species in nearly all diameter classes were greater in the shelterwood than in the control. The shelterwood cutting method is recommended for use in young-growth, mixed-conifer stands.

"This book is for the person who lives in the tropics or subtropics and is interested in native plants, who wants to know about plants that are useful, who loves to watch plants grow, and who is willing to work with them. Such a person might ask questions like, Where will they grow? How do I grow them? Are they good to eat? How are they used? What are their names? These questions and more are answered here."--Préface
