SAVIOR OF THE MOUNTAIN: MARY LEOLIN BOWERMAN (1908–2005) by Barbara Ertter ...... 3 Mary Bowerman was a strong force in California botany throughout her long life, and significantly contributed to the saving of Mt. Diablo, one of the prime open spaces east of the San Francisco Bay area. Her life and achievements are reviewed in this tribute by her friend and collaborator on the revised flora of Mt. Diablo.

A NEW MODEL FOR CONSERVATION PLANNING: VEGETATION MAPPING IN WESTERN RIVERSIDE COUNTY by Julie M. Evens and Anne N. Klein ...... 11 The California Native Plant Society, working collaboratively with the California Depart- ment of Fish and Game and Aerial Information Systems, has created a field-based inventory and a fine-scale map of vegetation, based on state and national classification systems. These products are particularly valuable to those involved with conservation planning efforts which represent, model, and monitor vegetation.

THE UNCERTAIN FUTURE OF IONE’S RARE PLANTS by George Hartwell ..19 Millions of years in the making, one of California’s unique natural resources is at risk of oblivion, the result of at least two insidious impacts. One is a plant pathogen; another is the malignant growth of commercial, industrial, and residential development. In this article on the rare plant species of the Ione Chaparral plant community, the author explores the manmade aspects of both threats, and whether their relentless momentum can be reversed.

A NATIVE PLANT GARDEN IN THE BERKELEY HILLS, PART ONE by Jenny S. Fleming ...... 25 A steep slope in the Berkeley Hills facing the Golden Gate Bridge is the setting for one of California’s premier native plant gardens. Created by Jenny and Scott Fleming over the course of 50 plus years, this unique half-acre garden features a redwood forest floor planting, a Sierran meadow of grasses, wildflowers, and bulbs, and a stunning rock garden filled with countless treasures.

SPRING WILDFLOWERS FROM GRASSLANDS AND OAK WOODLANDS Photographs by Barbara Ertter, John Game, George Hartwell, Carl Jones, Steve Matson, and Linda Vorobik ...... 29 Enjoy a selection of photographs of spring wildflowers that might be found in your local grassland or adjacent oak woodland, or that you might find while enjoying the trails of Mt. Diablo in Contra Costa County (see B. Ertter’s article on page 3).
