But first, today’s lesson in Los Angeles’ changing landscapes is a modern-day parable about the joys and challenges of creating native habitats on public lands.

Case in point: The lovely and puzzling Westwood Greenway. When completed in October 2020, it was an oasis of burbling streams and fragrant native plants along a wide, curvy trail between Overland Avenue and Westwood Boulevard next to Metro’s Expo line.

The project was a triumph for the Rancho Park community members who lobbied hard against early plans to build a 170-space parking lot on the site to serve Metro riders. They envisioned an inviting green space for the neighborhood and an eco-friendly showcase for turning unused nuggets of city land into lush native plant habitats for birds, pollinators and other local critters.

Except for people, as it turns out.

Nearly three years later, Westwood Greenway is still behind a locked gate and rarely open to the public except during volunteer work sessions to keep it weeded (city maintenance has been spotty) and free guided tours on the third Sunday of every month and by appointment.

See, the greenway was funded as a stormwater capture project, using city and state water improvement funds. The burbling brook was designed to capture water running through neighborhood gutters, collecting road dirt, dog urine and who knows what else, and clean it by exposing the water to sunlight and filtering it through native plants like cattails before it returns to the storm drains and, eventually, the Santa Monica Bay.

Those funds also called for adding native trees and plants along the third-of-a-mile stretch between Westwood and Overland “to help educate the public about sustainability,” according to a statement from the city, and a wide, curvy “trail” actually designed to be an access road for maintenance vehicles.

The city has done many stormwater capture projects as part of its quest to clean and reclaim water, but few of them include a native plant/habitat component, said Ida Meisami-Fard, senior civil engineer for the L.A. Sanitation and Environment Department.

And therein lies the rub: This serene, fragrant site requires regular care to keep weeds from overrunning the native plants, a job managed mainly by the community volunteers who lobbied for its creation, a nonprofit group called Westwood Greenway Inc., said President Annette Mercer.

This year, however, the cattails in the stream grew so tall and thick that they impeded the stream flow, making it run over its banks during this winter’s heavy rains. So the city finally came in to fix the problem.

Habitats are supposed to be a little wild, with sprawling shrubs and leaf litter on the ground, creating a natural mulch, shelter, food and nesting materials. But when the city landscaping crew came in early May to dredge out the cattails in the stream, they damaged some native plants with their machinery. And to the volunteers’ consternation, they tidied up the site like a traditional no-leaf-left-behind landscape.

“It was extremely upsetting that even after asking that the native plants not be ‘neat and tidy’ and the native trees not be pruned (it is the wrong time of year), many plants that were not in the creek and not in the way of equipment were mowed, damaged or removed,” Mercer wrote in a May 16 letter to L.A. Sanitation and Councilwoman Katy Yaroslavsky.

“There was no reason for the clearing, and it disturbs the native bees, the soil invertebrates and all the other animals that use the area for habitat. It is the opposite of the habitat restoration aesthetic being promoted,” Mercer added.

The results of her letter were somewhat gratifying, Mercer said. Representatives from L.A. Sanitation and Yaroslavsky’s Council District 5 office met with board members shortly after. Meisami-Fard confirmed that the city has chosen a regular maintenance crew for the site with expertise in California native plants and is negotiating a start date for sometime in late summer or early fall.

Leo Daube, Yaroslavsky’s communications director, said that beginning July 1, the new city budget includes money to install fencing and gates that can be easily opened and closed for public access and maintenance.

He and Meisami-Fard said it likely will take six to nine months to draw up plans for creating that public access and to address other questions, like who will open and close those gates each day and whether the site will include a port-a-potty and even garbage cans (the can previously at the site was removed after it was set on fire).

Caution tape hangs from native plants along the east edge of the Westwood Greenway, to protect them from damage. A city maintenance crew mistakenly weeded out native grasses in the area.

This highlights the reality: Wild areas may be beautiful, but they’re also a problem for the city, which has to worry about liability issues and security for surrounding neighbors. And it does need access to do the maintenance that the site requires, Meisami-Fard said.

“We’re really grateful to the community group who have been volunteering their time tremendously [to keep the site weeded], but native plant vegetation gets really strong root systems that can cause blockage and flooding,” she said. “We want to be a partner with them, and take into account their vision of an urban forest, but if it’s open to the public, we can’t just let it be overgrown. We have to find common ground and we need to work together to carve out that path.”

“You pick your battles,” Mercer said ruefully, looking at the shorn Cleveland sage and shaped-up sagebrush. At least, she said, the remaining plants still provide habitat for local animals, and someday, she has faith the Greenway will be open to humans too.

In the meantime, you can visit the site from 10 a.m. to noon on July 16 for a free formal tour. Enter at the west gate off Westwood Boulevard.

— Saving the next P-22 starts with a million ‘hyperlocal’ seeds and a bare-bones nursery. The Wallis Annenberg Wildlife Crossing over the 101 Freeway won’t open till late 2025, but the work of collecting native seeds and building a nursery to grow them has already begun.
