Sequoiadendron giganteum (Cupressaceae) at Lake Fulmor, Riverside County, California.

摘要

A GPS census made on 19 Jun 2012 of the Lake Fulmor area, northwestern San Jacinto Mountains, Riverside County, California, revealed seven trees of the Sierra Nevada endemic Sequoiadendron giganteum (Cupressaceae). The trees occur in a 234-meter-long narrow strip along the northwestern side of the lake. The population appears to be naturalizing. The largest tree (45 cm DBH, about 20 m tall), planted in 1980, is reproductively mature. Its six offspring to the northeast and southwest are 3-5 m tall and do not presently bear cones.
