Descanso Gardens on Saturday will unveil an oak woodland that provides a glimpse of what Los Angeles might have looked like before 16th century European settlers and their livestock arrived and forever changed the Southern California landscape.
The 7.7-acre plot of land sat largely untended between Descanso’s Rose Garden and the California Natives section for decades, overrun with invasive eucalyptus trees and other nonnative plant species and housing a plant propagation nursery and green waste dump, David Brown, Descanso’s executive director, told Times Community News.
The site of Descanso founder Manchester Boddy’s recreational cabin and a seasonal pond he had installed nearby, the revamped woodland is the garden’s first new addition in 30 years.
“When you talk about expanding a botanical garden, you don’t necessarily think about bringing the natural landscape back,” Brown said, invoking the idea of gardens as showcases for exotic and rare species. “But now, it’s the native habitat that is exotic, because it’s been mucked up, it’s been changed, altered by human interests.”
Five years ago, Brown and former head horticulturalist Brian Sullivan came up with the idea to return the land to a much earlier iteration of the L.A. basin, before Spanish missionaries hit California’s shores in the late 1700s, bringing with them agriculture, hungry livestock and stowaway seeds tucked into clothes, cargo and animal hides.
Those three influences nearly obliterated the pristine prairie ecosystem, home to a rich biodiversity of plant and animal species. Only recently have naturalists shown an interest in reviving native landscapes for the enjoyment and edification of the public.
Brown said he and Sullivan made several trips to the Santa Rosa Plateau Ecological Reserve in Riverside County, one of the few remaining natural prairies in Southern California, for inspiration and research.
The project, estimated at $1.2 million, was completed using funds from Proposition A, committed by Los Angeles County Board of Supervisor’s District 5 under Mike Antonovich and awarded to the nonprofit L.A. Conservation Corps, which provides job training and work experience to at-risk youth.
Together with staff, corps members hand-weeded the parcel, sparing native plants while transplanting another 30,000 cuttings and seedlings grown specifically for the area. An equal number are scheduled for planting in the near future. But the coast live oaks (Quercus agrifolia) were always intended to be the main attraction, according to Rachel Young, Descanso’s director of horticulture and garden operations.
“Oaks are the architecture under which the garden thrives,” Young said, adding that most Descanso oaks must compete with camellias and other thirsty species for vital water. “We wanted to create a place where there were oaks and they could just be.”
