During these same two years of 1931 and 1932, Nesta Dunna also explored in the Santa Monica Mountains and inland near Riverside. It is interesting to note that the two areas where she focused her scientific collecting, namely the Channel Islands and Santa Monica Mountains, are now both being preserved as National Parks, in part due to the wild native plants and native wildlife found there. Five of the eight islands are included in the National Park. However, roughly 50% of the eight island's acreage is fully protected in National Parks. Nearly 50%, or three islands have only limited protection because two are managed the US Navy that uses bombs on one of them. The other island is largely controlled and owned by a private company. Similarly, only about 50% of the Santa Monica Mountains is protected in parks and preserves, the balance is in private ownership, with much of it already developed into homes and businesses. Nesta Dunn knew the Santa Monica Mountains when they were much more wild. She visited the Channel Islands, when there was a lighthouse keeper family on Anacapa and Santa Rosa Island was a private ranch. Today, those two islands are much better protected for wild native plants under the National Park Service, than when she visited the islands.
My own ongoing research focuses on California natural history, particularly the biogeography of southern California, from wetlands, mountains, deserts, prairies, seashores, to the history of natural history of California. The information and knowledge gleaned is used toward the application of restoration and recovery of natural areas and wild open spaces not just in California, but also Hawaii, Mexico, Nevada, and a few other areas in the western United States.
Investigation into the life history of Nesta Dunn as a botanist has come via an interest, not only in Joseph Ewan as her husband and colleague, but also because Nesta Dunn explored the California Channel Islands and the Santa Monica Mountains near UCLA. Interestingly, both of these places are now managed and owned by the National Park Service. Both areas are undergoing every effort possible to restore and recover native plant wildflowers and native wildlife. UCLA has been at the forefront of interest in the ecology of both the Santa Monica Mountains and the Channel Islands.
There is a fair amount of knowledge of the flora and fauna of the Channel Islands and Santa Monica Mountains at UCLA in both the biology and geography departments. My alma mater, California State University Northridge, also has some important collections, contributed to the university herbarium and the zoology collections, while I was student. Thus far, a small nugget of information regarding Nesta Dunn and her collecting on the Channel Islands and Santa Monica Mountains has been located at the UCLA Herbarium. Future research will discern addition information and knowledge.
Additional research into Nesta Dunn as a scientific botanist has included a visit to the Tulane University Herbarium in New Orleans, Louisiana in February, 2003. In the future, a visit is to be hoped for to the Missouri Botanic Garden in St. Louis, Missouri, as time and finances permit it.
My research at UCLA in the Herbarium and Library is preliminary but ongoing and will continue as funding and time allow. Miss Dunn's botany professor at UCLA was Doctor Carl Epling. In 1931-1932, UCLA was only three years old, and Nesta Dunn would have been one of his first students, and certainly one of the first of his woman students. In fact, she watched over and baby-sat for the children of Carl Epling. Some of her botanical exploration in the Santa Monica Mountains was done togehter with Carl Epling, perhaps on a class fieldtrip. Listed below is a preliminary table of her collecting trips around southern California in 1931-1932.
