The current environmental status of this species within its natural growth range in the states of California and Oregon is officially classified as Rare

Distribution Overview
The growth range of the species extends from extreme southwestern Oregon south to central California in the fog belt, a coastal strip of land which is about 5 to 25 (8 to 56 k) miles wide. Redwood forms pure stands in lush dense forests, and may be found in association with Douglas-fir, Port-Orford cedar, and mixed conifers. It prefers mostly alluvial soils on flats and benches or terraces.

Tree Size
Tree height is 60-70 m
Trunk diameter is 100-150 cm


The world's tallest tree is a Redwood, measuring about 368 feet (112 m) in height.

Product Sources
Redwood is readily available in the lumber form, and is typically priced competitively with other construction timbers. Redwood burls are available in limited quantities on the west coast of the United States, and are usually priced in the expensive range.

Substitutes
Alerce (Fitzroya cupressoides) is a possible substitute

Comments
Abnormal Growth Features

Although virgin forests of Redwood still exist in several state parks, as well as in the Redwoods National Parks and along the Redwoods Highway, there are still some concerns about the status of the species outside these areas. While some people advocate that the future of Redwood can be assured through planting in tree farms and regeneration of seed trees after selective logging, others feel that the species should be conserved and maintained at its present levels.
