The Emerald Necklace Expanded Plan plant palette was developed as an easy to reference list for restoration and greening projects in the public spaces throughout the Emerald Necklace.
The source documents for this plant palette are the Los Angeles River Master Plan Landscaping Guidelines and Plant Palettes (January, 2004) and
the San Gabriel River Corridor Master Plan (June, 2006).
The plant lists were developed by a cross disciplinary team of professionals concerned with protecting the seed
bank and biological integrity of the river corridors – to be used by jurisdictions participating in greening
and re-vegetation of the river corridors. This multi-disciplinary team included: Ecologists, Landscape
Architects, Botanists, artists, the native plant society, local conservancies, the County of Los Angeles
Department of Public Works, the US forest Service, the National Park Service, City Parks and Recreation
departments, the Audubon Society, Friends of the Los Angeles River and the local watershed councils.
We have found that plant managers at school districts and other facilities; both adjacent to the river and
within the urban core are equally interested in planting California Watershed sensitive plants for their
water conservation properties, ecological value, habitat enhancing properties as well as their heritage/
educational value. This is an exciting trend.
Supplemental source documents have included the Army Corp of Engineers Plant list for ecological
restoration at Santa Fe Dam as well as plant list for restoration of Monrovia Canyon within the City
of Monrovia and nestled against boundary of the Angeles National Forest. The Angeles National Forest
Management plan September 2005 – Los Cerritos Watershed Impacts Report were also consulted.
This section of the document is divided into the following categories:
• Grasses, Sedges and Rushes
• Groundcovers and Vines
• Shrubs and Subshrubs
Each plant is labeled to identify which are appropriate to be planted along the San Gabriel River, Rio
Hondo River, or Park/School sites not located near the Rivers.
We commissioned Barbara Eisenstein to take original photos of many of the plants as high quality
photos were not always available from the nurseries. Photo credits also include: Tree of Life, El Nativo,
Martin Hale, and Ron Luxemburg.
Our hope is to encourage people to reconnect to their environment and become excited about
changing our ethic and esthetic of landscape architecture to include the multiple benefits of planting
natives. Natives mitigate the effects of Climate Change by reducing negative impacts on valuable natural
resources and air quality, in addition to reducing greenhouse gases.
