Our Project Sites
This page is still very much a work in progress. We've worked at a lot of sites throughout the years and it'll take a while for us to write them all up.
Santa Rosa Island
Santa Cruz Island
San Nicolas Island
San Clemente Island
Hammond's Meadow Preserve
CIR is working with many project partners to preserve and manage the native coastal habitat of the Hammond's Meadow Preserve, known as the Chumash village Shalawa. Visit the Hammond's Meadow Project web page for more info.
Santa Ynez Band of Chumash Indians Reservation Restoration
CIR is working under contract with the Santa Ynez Band of Chumash Indians to eradicate multiple large stands of Arundo donax in a tributary of the Santa Ynez River. This work is taking place on the Chumash reservation in the Santa Ynez Valley. CIR worked closely with Chumash fire crews to cut and remove the Arundo while preserving the native flora in this sensitive and unique natural area. Chumash and CIR environmental staff continue to monitor the Arundo eradication.
Santa Ynez Valley Puna Grass Eradication
CIR worked in partnership with the Santa Barbara County Agricultural Commissioner's office to eradicate an infestation of punagrass (Acnatherum brachychaetum) located on a horse ranch on Happy Canyon Road in Santa Ynez. Puna grass is an "A" rated noxious weed and is a tough, spikey bunchgrass that interferes with harvest machinery, and horses and cattle find unpalatable.
Refugio Creek Arundo Removal Project
From 2006 to 2009, CIR worked to remove Arundo donax from Refugio Creek above the campsite and beach. CIR worked in cooperation with The Land Trust of Santa Barbara County, the Cachuma Resource Conservation District, and the Santa Barbara County Flood Control District.
The project involved:
- Removing at least 100 separate patches, on 4 acres, of Arundo donax, as well as several smaller areas of other invasive plant species detrimental to the wildlife ecology of Refugio Creek.
- Stabilizing the creek bank on over one mile of Refugio Creek to reduce the chances of large-scale bank failure, future sediment deposition into the creek, and bank-cutting that undermines riparian vegetation and habitat values and threatens high-quality orchard land.
- Re-establishing native riparian habitat on 17,000 square feet along the creek corridor by planting more than 3000 trees, shrubs and herbaceous annuals. These plantings stabilized the creek banks, created shade to cool and conserve water in the creek, and provide excellent habitat for a wide array of local wildlife.
- Conducting three years of post-installation monitoring, re-treatment and replacement planting to ensure a successful outcome.
- Demonstrating a model for collaboration among private agricultural landowners, government agencies and non-governmental organizations to address watershed enhancement on the Gaviota Coast.
Gaviota Coast Artichoke Thistle Removal
CIR is worked with the County of Santa Barbara Agricultural Commissioner's office to eradicate artichoke thistle (Cynara cardunculus) on the Gaviota Coast. Artichoke thistle is a difficult to remove invasive weed that is very destructive to native habitat.
Arroyo Hondo Preserve Invasive Tree and Invasive Plant Removal
CIR has performed extensive invasive plant removal projects for the Land Trust of Santa Barbara County on the Arroyo Hondo Preserve on the Gaviota Coast. Our work at the reserve takes place in close proximity to several listed/threatened/endangered species including southern steelhead trout, red-legged frogs and tidewater goby. CIR is trusted to perform careful and professional work in highly sensitive habitats at Arroyo Hondo. For more than 10 years CIR has worked at the reserve to removing invasive trees, periwinkle (Vinca major) and onion weed (Asphodelus fistulosus).
Andree Clark Bird Refuge & SB Zoo Invasive Plant Eradication and Re-vegetation
CIR worked with the Santa Barbara Zoo and the City of Santa Barbara to restore a section of the Andree Clark Bird Refuge on zoo property. Operating under funding from the Southern California Wetlands Recovery Project, CIR removed over 100 invasive Myoporum trees, plus cape ivy (Delairea odorata) and many other invasive species. We also planted several hundred native species at the restoration site with the help of over 250 volunteers!
Working under contract for the County of Santa Barbara Agricultural Commissioner's Office, CIR has treated many stands of Arundo donax in Hidden Valley Park & other extensive areas along the Arroyo Burro Creek in Santa Barbara.
CIR worked in partnership with South Coast Habitat Restoration, Carpinteria State Beach and the Carpinteria Creek Coalition (with funding provided by the Southern California Wetland Recovery Project) on a innovative project to remove iceplant at the foot of Carpinteria Creek at the State Beach. CIR staff and volunteers first "solarized" the iceplant (eradicated it by placing sheets of black plastic over the iceplant thereby heating it and depriving it of light). Then, while leaving the dead iceplant in place, CIR staff and volunteers installed nearly 2000 native plants after the plastic was removed.
Coal Oil Point Reserve
CIR has a longstanding association with the Chedale Center for Biodiversity and Ecological Restoration (CCBER) at Coal Oil Point Reserve on the Goleta Coast. Coal Oil Point Reserve is one of many open spaces preserved and managed by the UC system for the purposes of research. CIR has conducted dozens of important and extensive invasive tree and shrub removal projects on the reserve over the last decade and we are proud to continue to collaborate with CCBER and UCSB on the preserve.
Elings Park Invasives Removal and Native Plant Installation
CIR has treated Pampas grass in Elings Park in Santa Barbara. Much of this work has occurred in very rugged terrain, and the plants were growing directly with native coastal sage scrub plants. We have and are currently restoring native plants to the vacant areas.
Lake Los Carneros
From 2009 to 2011, CIR restored sites along Los Carneros in Goleta. With funding from the Goleta Valley Land Trust, the project involved removal of key invasive plant species from the perimeter of the lake followed by revegetation of the area with native plants. More than 350 volunteers helped with the various stages of restoration. The project emphasized community involvement and education, and enhances important bird habitat and directly benefits Santa Barbara honeysuckle (a species of special concern.) We are proud to have worked closely with the City of Goleta on this project.
CIR treated Arundo donax in rugged terrain in Mission Canyon near the Santa Barbara Botanic Garden.
Montecito Arundo Eradication
CIR has removed multiple large stands of Arundo donax under contract with the Montecito Fire Department at various locations along creeks in Montecito.
More Mesa Pampas Grass & Knapweed Eradication and Bluff Restoration
CIR has worked under contract with the Santa Barbara County Agricultural Commissioner's office to eradicate Papas grass (Cortaderia selloana) and Russian knappweed (Centaurea repens) at various locations on More Mesa in Goleta.
We have also conducted some erosion control measures for the Homeowners' Association by utulizing field staff trained in rappelling.
Parma Park Invasive Plant Eradication
CIR has worked under contract with the City of Santa Barbara Parks Department to remove several invasive species in Parma Park. Our work has involved careful invasive eradication in native plant communities.
San Marcos Foothills Restoration
Since 2010, Channel Islands Restoration (CIR) in partnership with the San Marcos Foothills Coalition (SMFC) has restored habitat for native animals in several critical areas on the Preserve. Financial support for these projects came from the SMFC, the Goleta Valley Land Trust and outdoor retailers, REI and Patagonia.
These projects were designed to improve the native plant communities that support species such as burrowing owls, breeding grasshopper sparrows, breeding white-tailed kites, raptors, and other native animals.
Two of the larger projects were designed to increase biodiversity and ecological function on approximately three acres of burned riparian and coastal sage scrub habitat adjacent to Atascadero and Cieneguitas Creeks. Long-term grazing in these areas favored the growth of non-native and invasive plants, and the area was damaged by the Jesusita Fire in 2009.
Following the fire, both sites saw a marked increase in the presence of non-native invasive plants. CIR started by removing invasive plant species with the help of hundreds of volunteers, and and this was followed by the planting of more than 4,700 native plants grown from locally collected seed.
In addition to the creekside projects, CIR has been removing invasive plants along trails, particularly in native grassland areas and wetlands. We have also planted natives at the Preserves' Via Gaitero entrance. As of this writing (August 2015) CIR has worked with a total 1,319 volunteers on the San Marcos Foothills Preserve!
San Roque Creek Arundo Eradication
CIR treated several large stands of Arundo donax on San Roque Creek under contract with the County of Santa Barbara.
Santa Barbara Botanic Garden Invasive Plant Control
CIR worked under contract with the Santa Barbara Botanic Gardens. We have treated several key invasive around sensitive native plants in the garden.
Hendrick Ranch Nature Area
CIR treated invasive (including Arundo donax) at the Hendric Ranch Nature Area on the Santa Clara River. We worked in partnership with Coastal Restoration Consultants.
McGrath North Shore Dune & Wetland Restoration
CIR is working with ARCADIS US to restore habitat near McGrath State Beach in Oxnard. The project includes wetland creation and dune enhancement on two parcels totaling nearly 30 acres. A major aspect of the project is protection of the Ventura marsh milk-vetch (Astragalus pycnostachyus var. lanosissimus), an endangered species that grows on the North Shore site. The milk-vetch was thought to be extinct until a small population was found growing at the North Shore site. CIR staff carefully removed invasive plants that are threatened the endangered milk-vetch.
Ormond Beach Dune Restoration
CIR worked under contract with The Nature Conservancy to eradicate Myoporum trees and iceplant at Ormond Beach in Oxnard.
Santa Clara River Arundo Eradication
City of Santa Paula
CIR partnered with Bio Resource Consultants to restore 5 acres of habitat on the Santa Clara River near Santa Paula. The project createdand enhanced riparian habitat to increase wildlife diversity, including the southwestern pond turtle. This project was implemented to mitigate the impacts of the City's new waste water treatment facility.
The Nature Conservancy
CIR has treated giant reed (Arundo donax) at three properties on the Santa Clara River owned by the Nature Conservancy (TNC). We continue to work on TNC property in partnership with Coastal Restoration Consultants.
Conejo Open Space
CIR worked with the Conejo Open Space Foundation to remove invasive plants at various locations in the Conejo Open Space.
Rice Ranch Restoration
CIR worked with ARCADIS US to restore portions of the Rice Ranch area in Orcutt.
Peck Park Canyon
CIR is helping several agencies to remove non-native vegetation and to plant natives at Peck Park Canyon in San Pedro as part of a larger project. Peck Park Canyon is a 31 acre corridor located within Peck Park. The project includes erosion and sediment control, flood control and water quality improvements through the infiltration of storm water. CIR’s work focuses on high priority locations in the canyon streambed.
Saddle Peak Spanish Broom Eradication
Santa Monnica Mountains NRA
CIR worked in close cooperation with the Santa Monica Mountains Trails Council and the Santa Monica Mountains National Recreation Area to eradicate Spanish broom (Spartium junceum) at Saddle Peak in the National Park. CIR staff trained volunteers in eradication techniques and helped supervise volunteers.
Sisquoc River Tamarisk Removal
Channel Islands Restoration is working to eradicate non-native invasive Tamarisk species in the Sisquoc River and Manzana Creek. The objective of the project is to restore and maintain habitat for riparian dependent species such as the federally listed arroyo toad, California red-legged frog and steelhead trout.
The project is located within the Los Padres National Forest in Santa Barbara County, California on the Sisquoc River system including Manzana Creek and other tributaries. Specifically, the areas treated will be on the main stem of the Sisquoc River and its tributaries including Foresters Leap Canyon, Manzana Creek and its tributaries from the headwaters on the east to the Forest boundary on the west (approximately two miles west of Manzana Camp).
Tamarisk (also known as salt cedar) is a deciduous shrub or small tree from Eurasia; thus it loses its leaves each year, making it difficult to observe during the period when it has no leaves. Tamarisk has a deep, extensive root system.
Mature tamarisk plants are able to reproduce from roots. Flowering branches are mostly primary or secondary branches. Each plant can produce as many as 500,000 seeds annually, and can produce seeds throughout the growing season. High stress induced by fire, drought, herbicides, or cutting can increase flowering and seed production. The seeds are dispersed by wind and water. Seeds are small with a tuft of hair attached to one end enabling them to float long distances by wind and water. Seeds are shortlived and do not form a persistent seed bank. However, they can germinate within 24 hours of dispersal, sometimes while still floating on water. Seeds produced during the summer remain viable for 24 to 45 days. Winter longevity is approximately 130 days. Seed mortality is generally due to desiccation. If seeds are not germinated during the summer that they are dispersed, almost none germinate the following spring (http://www.fs.fed.us/database/feis/plants/tree/tamspp/).
Tamarix trees on floodplains can be difficult to kill, requiring several treatments. The root systems of trees on floodplains are more extensively developed near the ground surface, due to repeated scouring and removal of limbs by floods, and can send up shoots where none existed at the time of initial treatment.
