Nina and I met up at the Test Plots to monitor the existing species and create labels for plants when necessary. We met at 10am on a Sunday. The log borders are working well as a way to differeniate the plots from the path. It seems that the most successful plots have a thick 3-5” layer of mulch.
While going through and taking note of successful species two park visitors came up to us and told us they were volunteers and a part of the larger recent natives planting at Rio. The area around the test plots had 50-100 new young sprouts that were planted.
One of the volunteers mentioned noticing what seemed like a pest growing on one of the oak tree saplings. She remarked how much she loved the species and knew how long they take to grow, so she wanted to keep an eye on it to give it the best chance possible. We walked over and saw a red beetle and white substance underneath the oak leaves (eggs, fungus, foam?). We took pictures and notified the Parks Coordinator. We then completed our assessment of the plots and infilled metal labels in areas that needed it most. We were at the park for around an hour.

Weather
High of 72, Low of 59 degrees
We received the first sprinkle of rain earlier this month, Prior to that it has not rained since April, which is typical of our summer dry climate.
Tests
The seeded only plots are visibly different from the plots planted with 1-5 gallon plants. Not as variety visible in the fall with the seeded plots. This could be due to the seeded species being mostly annual wildflowers. Check plantlist to vertify hypothesis.
How are the plants doing?
The plants look good, none are visibly in distress. Many of the plants have gone to seed or fruit. California Buckwheat provides a nice color through its seeds to compliment the evergreens in the Fall. After monitoring the test plots for two years we’ve noticed certain species are thriving
Successful species:
Future Activities
Note spontaneous growth in the Spring. Many of the species have grown for 2 years, infill planting to fill in the gaps as next steps

Successful species:
- Eriogonum fasciculatum - California Buckwheat
- Isocoma menziesii - Menzies' Goldenbush
- Baccharis pilularis - Coyotebrush
- Asclepias fascicularis - Narrowleaf milkweed
- Muhlenbergia rigens - Deergrass

Future Activities
Note spontaneous growth in the Spring. Many of the species have grown for 2 years, infill planting to fill in the gaps as next steps
- Mulch beds with depleted mulch layer. 3-5” thick layer of wood chip mulch is optimal.
- Replace labels and provide labels for all plants
- (Tongva, English, Botanical names)
- Can this be done before the Oct 17th?
- Update “What is Planted Here” laminated sheets
- Make this signage more visible
- Increase vegetation density
- Increase variety of species
- Struggling species
- Penstemon spectabilis (Showy Penstemon)
RIO AFTER 2 YEARS
DATE: October 06 2022
The Rio plots were planted in the Fall of 2020. A class of landscape architecture students partnered with CA State Parks and a local group the Abuelas de Rio. After two years, we wanted to share some reflections on how they are doing and what we have learned.

Q: Can we replicate Test Plots in other places?
Yes! our 2nd location at Rio has been very successful. It’s been a completely different process, site and community than at Elysian, so that is very exciting and we’ve learned a ton. For example, the site prep needed to change because Rio is urban fill as a former railyard (as opposed to the naturalized areas of Elysian). The Grow/kill strategy to flush out the weeds was not very successful at Rio b/c the ground was so compacted. We ended up removing bermuda grass, thistle, etc with pickaxes.
Q: What are your key lessons learned so far?

Q: How did you adapt for different community needs?
- At Rio we work with a group of elderly Spanish speaking abuelas - with no email or social media. They come to the park in the morning for a walk and some gardening. It was difficult during the pandemic, but we’ve started to create a weekly time to meet on Monday mornings that is organized by Luis Rincon, a community engagement coordinator who works for CA State Parks.
-
This site is also much sunnier and exposed and requires meeting earlier in the morning during the summer.
Q: What are your key lessons learned so far?
- Pioneer species taking off (Isocoma menziesii-- Goldenbush, Encelia californica -- CA Bush Sunflower).
- For the seed only plot, in the first year, seedlings of chia, black sage, lupines, buckwheat and annual wildflowers were present - from a mix that Theodore Payne made for us based on the historical riparian ecology. In 2nd year, the seed only plot was composed largely of Buckwheat (Eriogonum fasciculatum).
- Seed/plant combo plots more successful than seed only or plant only.
- Sheet mulch and thick layer of mulch (4-6”) has been effective at suppressing Bermuda grass, but it can still creep in from plot edges
What challenges have you faced?
- We watered almost every week for the 1st year (maybe too much? Huge growth quickly and found scale on some plants like Malosma)
-
Baby oak and walnut trees (not in plots) died b/c not watered / trampled. Need better cues.
LUIS RINCON, SUPER STEWARD
Rio de Los Angeles State Park
By Hannah Flynn & Dani Velazco
current and former Test Plot interns
Starting in early 2022, we conducted a series of seven interviews with “Super Stewards” - members of the Test Plot community who are stewards of community and of the environment. Our conversations covered personal histories, what it means to be a steward, and what the future of community-tended green space can be.

![Meet Luis Rincon, State Parks Community Engagement Coordinator]()

Rio de Los Angeles State Park wasn’t always a park. For a long time, it was part of the Los Angeles River floodplain and agricultural fields. That is, until the massive Taylor Yard rail yard was constructed, roughly coinciding with the concretization of the Los Angeles River. It was operated as a rail yard until 1985, when it closed operations. To learn the story of how Rio became a park, we met with Luis Rincon, State Parks Community Engagement Coordinator, on an unusually warm and sunny winter day. We sat down together near the Test Plot, in the grass, soaking up the sun. According to Luis, the abuelas del Rio, longtime residents of the neighborhood and park volunteers, are to thank for their dedicated advocacy work to turn the brownfield into a park for their grandchildren to play.
The location was perfect: because of its proximity to the river, it could connect kids to the river, its ecology, and its part of the city’s history. The abuelas found an opportunity with California State Parks to turn this parcel of land into a park because of its significant natural value as a riparian zone. However, the abuelas and other community groups also wanted to have soccer fields and basketball courts, which State Parks does not administer, so the park is run as a partnership between the City of Los Angeles and State Parks.
Luis noted that on the administrative side, State Parks was keenly aware of a statewide relevancy problem: the people visiting their parks didn’t reflect the rich diversity of the state. The advocacy work of the abuelas aligned perfectly with State Parks’s own initiative to build more urban parks to “bring parks to the people.” As Luis started with State Parks, he was drawn to Rio because of the abuelas’ passion and vision of green space for their community. Getting to meet them and work with them was inspiring. “I remember when I first got here, everything in the landscape was small,” he recounted, underscored by the dappled shade provided by the now-mature toyon we sat beneath.
A native Angeleno himself, his connection to the outdoors began with family camping trips up near Yosemite. One of his earliest memories was jumping on a log and falling into a creek, a memory he associates with happy senses of freedom and being with family. Growing up in Northeast LA, Luis served as a community ambassador as part of a program called the Conservation Career Development Program (CCDP), a Student Conservation Association (SCA) program serving inner-city youth. Wanting to give back to his community, he switched to social work following college graduation. Eventually, he came to the realization that while social work was important and effective, community health is inextricably linked to open, green space, which brought him back to working with nature. And while situated in an urban setting, Rio’s 20 acres of nature is just enough to provide human health benefits and habitat benefits, such as creating habitat for an endangered bird, the Least Bell’s Vireo.
Working as an Community Engagement Coordinator for State Parks, Luis is able to build community and expand who gets to benefit from access to nature. He insists that he can’t do it alone, that it’s “always about finding the right partners who have aligned thinking.” Through partnerships with organizations such as the Audubon Society and Test Plot, he’s able to organize more resources for the community, in turn strengthening the community’s relationship with the park. “It’s not just about parks, it’s about the people. The abuelas didn’t know that they would set 100 acres [as in the 100 Acre Partnership] in motion in Los Angeles where real estate is at a premium…it is always about just taking that first step.” The abuelas could not have imagined the long-term impacts to the nation’s second-largest city that their green advocacy work catalyzed.
