One of California's most unusual attractions is Sequoia Gigantea, the giant
sequoia, or giant redwood (as distinct from Sequoia Sempervirens, the coast
redwood) which grows in a very limited range in the high Sierra. Willard's book
clears away several misconceptions about the trees. The first is that they only
grow in the National Parks (Sequoia, Kings Canyon, and Yosemite) and most of
the trees can be viewed from the main roads. In fact, most of the sequoias grow
outside the parks, in National Forest land (with a few on private land), and
many of the 67 separately named groves must be reached by trails or primitive
dirt roads. The second is that they are endangered. Although many sections were
logged in the last century, and a few as recently as the 1950s, the majority
of old growth sequoias remain and are quick to regenerate in areas where they
were cut. Forest Service policy now is to protect all sequoias from cutting,
although they allow logging of other conifers in sequoia areas. In the parks,
they are given the benefit of controlled burns, and careful regulation of traffic.
In all, the sequoias are holding their ground quite well.
Most of the sequoia groves are concentrated in the southern Sierra, but the
northernmost is in Placer County, due west from Lake Tahoe. The true giants
are generally defined as 20 feet or more in diameter at chest height; the General
Sherman Tree is 21.6 feet at 16 feet above the ground and a volume of 52,500
cubic feet, but there are individuals approaching "giant" status to
be found in most of the groves (as well as stumps and snags of even larger trees).
Sequoias and redwoods are notoriously hard to photograph, but this book contains
many excellent, if small, color photos. It could use a few more maps, but the
directions for finding and exploring each grove are fairly clear. Many of the
finest groves are accessible only by arduous cross-country hiking, ensuring
that they will have very infrequent human visitation. This excellent book provides
a description of the sequoias in their natural habitats, and clear directions
for making some very enjoyable trips to explore this underappreciated resource.
