Book Description
"This impressive, streamlined new field guide to plants of California deserts is based on The Jepson Manual and is truly a handbook to be carried in the field. It offers new introductory discussions, many new illustrations, revised user-friendly keys, updated distribution information, flowering times. . . and handsome color photos of many species. This marvelous book demonstrates that our deserts are not barren wastes but treasure houses filled with an abundance of floristic riches."—Robert Ornduff, author of Introduction to California Plant Life "This is a marvelously useful guide to the plants of California’s deserts, clearly-written and well-organized. An invaluable companion to those who delight in the unusual and beautiful plants of these scenic areas."—Peter H. Raven, Director, Missouri Botanical Garden "This much-needed volume incorporates new information about the status and range of many California desert plants. This book will facilitate access to information about our deserts, and will lead to increased respect and attention to them. We warmly welcome it."—Jake Sigg, President, California Native Plant Society

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
Minerotrophic peatlands or fens in California's Sierra Nevada are small wet meadows surrounded by mixed conifer forest. The dynamics of vegetation change at the meadow edge and the ages and development of fens were investigated, in the Sagehen Creek Basin near Truckee, California, through the use of radiocarbon dating of peat, pollen studies, examination of processes of peat development and accumulation, stand age analysis of trees around peatlands, and evaluation of tree-ring variation. These approaches were used to evaluate both short- and long-term changes. Fens varied in age from more than 8000 years toless than 1000years old. Results suggest that overall fen development proceeds rapidly, with peat buildup dependent upon adequate moisture supply. During fen development trees repeatedly invade and retreat from the fen edges. The timing of invasions appears unrelated to events such as human disturbance and climatic change. Instead, changes are most likely to result from alterations in groundwater supply in interaction with tree establishment, longevity, and water uptake. Little evidence was found that accepted successional models which emphasize predictable and gradual vegetational development apply to fens in the Sagehen Basin.
