Capturing resident voices

Community voices are often missing from tree planning and policy decisions. To change that, the South LA Tree Coalition partnered with us to listen directly to local leaders—gathering their perspectives, needs, and ideas to shape more equitable, community-led urban forestry planning in South Los Angeles.

Our findings

We spoke to 34 community leaders; here’s what we heard:

Trees in South L.A.

play a role in community leaders’ perceptions of neighborhood identity, environmental conditions, as well as public health and safety.

Competing priorities, limited resources,

and lack of awareness present barriers to tree-related planning efforts in the community.

Community leaders value healthy tree canopy

in South L.A. and envision a future with equitable and intentional greenery supported by community initiatives and proper maintenance.

“It takes a village to get things done. No one agency can build the park; no one agency can maintain the park; no one agency can program the park; no one agency can do any of those things. Together, we can.”

Study reveals attitudes about lack of trees in South L.A.

One way to tackle the unequal distribution of trees across Los Angeles is to plant more of them in places lacking a robust canopy, like East and South L.A.

But a new study helmed by USC Public Exchange and the South L.A. Tree Coalition suggests the solution will need to be more multifaceted after decades of environmental injustice.
