Our Mission
To create an “Emerald Necklace” natural infrastructure network of green spaces (parks and trails) in underserved areas throughout the Los Angeles Basin, connecting the Mountains to the Sea and protecting urban communities from the threats of climate change.
Our mission is inspired by the 1929 Olmstead Bartholomew plan for an expansive greenway for Los Angeles, but sadly, due to changing government priorities during the 1930’s the plan was never realized. In 2003, in collaboration with community leadership we started creating parks and trails and a vision for a greener Los Angeles!Please consider making a donation today.

Natural Infrastructure Projects
Amigos De Los Rios – Emerald Necklace Group is a 501(c)(3) we have been creating natural infrastructure in Los Angeles since 2003. We have outlined an Emerald Necklace Vision Plan and completed 35 urban forestry and nature park projects, and we are particularly concerned with greening schools to make sure that students’ mental health, physical health and academic performance are protected and optimized. Our Urban Greening and advocacy work is in direct response to climate change.
For 16 years we have been focused on connecting urban residents in our most under-served areas to nature.
Below are a sample of our greening projects

ANGELES NATIONAL FOREST SIGNAGE PROJECT
Working to develop interpretive signage for the Angeles National Forest, the signage we create provides important information to forest visitors.
WHITTIER NARROWS TREE RESTORATION PROJECT
Working to improve the urban forestry canopy at various locations along the Emerald Necklace Parks and greenways.
LAC USC KECK WELLNESS CENTER
The Wellness Center will include fitness trails, jogging paths, exercise courts and age appropriate play equipment for visitors and staff to utilize.
PECK ROAD (WATER CONSERVATION) PARK
