Exploring Southern California
With an Expert Botanist
Over 100 years Ago
From 1898 to 1904

Reflections & Observations

LeRoy Abrams (1874 to 1956) explored the Los Angeles region and southern California in his search for native plants more than a century ago. He traveled far and wide looking for trees, shrubs, rare plants, and new species in all kinds of different areas from 1898 to 1903. He visited seashores at Ballona, Santa Monica, Topanga, and down the coast to San Diego. He explored the highest peaks of southern California such as Mount Baldy. He explored the deserts, prairies, rivers, and plains of Los Angeles and vicinity. He explored in an era before automobiles and airplanes. He was raised in southern Caliornia, attended USC, then transferred to Stanford University, but he became interested in the flora of southern California as a child and young adult. As a graduate student at Stanford University, he decided on a project that focused on the flora of Los Angeles and vicinity. He travelled by steamship down the California Coast to Port Los Angeles (Santa Monica) and sometimes by railroad down the coastline to downtown Los Angeles. After arriving in Santa Monica and Los Angeles, he traveled via electric trolley car, on foot, and horseback, totaling thousands of miles over the 5 year period. He sometimes would visit his mother in San Diego County, near his boyhood home, while working on his Los Angeles Floristic graduate project. As you can see, from his field journals, early books and articles in scientific magazines, his roots were in southern California. We are fortunate today, in 2004, 100 years after LeRoy Abrams' first Flora was written, to have such a valuable reference guide for ecological restoration and recovery of wild native plants in wild landscapes in various natural settings in Los Angeles and all of southern California. Native plants and sometimes non-native plants too, are the foundational basis for much of the wildlife in southern California. Animals such as birds, butterflies, lizards, frogs, salamanders, mammals, and other fascinating zoological creatures depend on native plants in natural area landscapes. If only we will slow down our lives to listen and see and touch. The art of simple observation, followed by gently recovering and restoring the genuine native flora and native fauna is possible in this geography of hope called Los Angeles and southern California. It would make our ancestors proud, happy and tearful with joy, particularly Le Roy Abrams, to recover genuine native plants that he first recorded over 100 years ago.
