This small tweak to California parks could help prevent fires

In a small section of Los Angeles’s Elysian Park, which spans the amount of land a single sprinkler head can water, a native plant experiment is underway that could change city parks for the better.

It’s called Test Plot. Combining native plant species, volunteer gardeners, and a not insignificant amount of weeding, the experiment is trying to find a new way for urban parks to counter ecological degradation and improve climate resilience. The project launched in 2019 and is now underway in parks across California, and the approach is showing that with the right plants and the right amount of effort, parks can be brought back into sync with the natural tendencies of their environments.

An experiment to spur native, fire-resistant plant growth

The idea came from the landscape architecture firm Terremoto, which formerly had an office just a few blocks from Elysian Park. “We saw that it was in need of some help,” says Jenny Jones, a landscape architect at Terremoto. Sections of the roughly 600-acre park were totally overrun by non-native species that crowd out more drought-tolerant, biodiverse, and fire-resilient species.

The city’s overstretched parks department had been managing these issues through annual brush clearance, but the non-natives would always grow back, along with the risks they posed. “It clears for fire, but it also mows down every single native species in its path,” Jones says. “We wanted to just challenge the regime of maintenance that we were seeing in the park.”

In conjunction with a longstanding community group associated with the park, Terremoto approached the city about using the firm’s landscape architecture skills to try a different approach. They asked if they could run a small experiment, planting native plants and doing some active, volunteer-based gardening. The city agreed, with the stipulation that the project be temporary.

A way forward for more sustainable parks

So in the fall of 2019 Terremoto hooked a hose to a water bib in the park, attached a sprinkler head, and started preparing a plot of land for a new kind of park planting. After a few rounds of watering and weeding, they planted dozens of one-gallon pots of native plants. Then, through regular maintenance and weeding sessions attended by a dedicated group of volunteers and enthusiasts, they simply helped the native plants thrive and stopped the non-native plants from moving back in. “We look to ecological restoration as a guide, but it’s not strict,” says Jones. “We lie somewhere between gardening and restoration.”

Within three years the native plants fully established themselves, and no longer required watering, nor much weeding. This one plot, just 30 feet in diameter, proved that the park could be restored to a more sustainable and ecologically balanced state.

A 30-foot circle in a 600-acre park might seem like a drop in the bucket, but the idea has caught on. Terremoto expanded its Test Plot approach to other parts of Elysian Park and other parks across L.A. There are now about 15 Test Plots, including four or five that have fully established plants.

By identifying degraded landscapes within parks, engaging with local groups already connected with those parks, and then asking city officials if they could temporarily intervene by adding native plants to those parks, they’ve been able to rethink planting and maintenance approaches at a larger scale. “There’s a little bit of figuring out how to pierce the bureaucracy and how to get around the otherwise really strict rules about engaging in that kind of work in public spaces,” Jones says.

But in the urban context, parks departments often have to deprioritize planting and maintenance in the face of the social issues they also experience, like vandalism, drug abuse, unhoused individuals, and compromised public safety. A volunteer project like Test Plot is a welcome intervention. “[Parks departments] simply don’t have the budget to do what it takes to actually take care of a complicated urban park that faces intense urban problems,” Jones says.

Test pilot’s appeal for time (and budget)-strapped cities

Test Plot is an appealing concept for parks who face such both budget challenges and the relentlessness of invasive species, and many across the state of California have allowed these interventions. Beyond half a dozen parks in L.A., Test Plots are adding native plants to parks in San Francisco, Berkeley, Daly City, Puente Hills, and Catalina Island.

Interest in the approach has grown so much that it’s been formally spun off into a non-profit organization by the same name. Jones says the organization has received interest from parks groups across the country, including in Minnesota and Rhode Island. They are also being hired as consultants for new park projects, including a redesign of the Los Angeles River Center and Gardens that will feature an ethnobotanical garden created by the Test Plot organization.

Jones says that a central element of all these Test Plots is community involvement. Volunteers are the backbone of the effort, and their ongoing engagement with the planting and weeding that Test Plot involves becomes a kind of reinforcement for the park’s vitality.

“We have people come and they form a bond with their park in a way that they didn’t before,” Jones says. “A lot of people love their parks because they take their dogs on walks, it’s where they run, it’s where they walk with their friends. But there’s a whole new layer of bonding when your hands are in the soil and you are taking care of the land yourself.”
