Middle Stewart Canyon Creek Restoration Project

The Middle Stewart Canyon Creek Restoration Project is underway! The project will rehabilitate a 10-acre riparian corridor overrun by invasive non-native species. Invasive non-native plants decrease riparian habitat water supply, increase fire hazards, and inhibit native plant growth. Highly flammable non-native species overwhelm and damage many riparian areas. In addition, non-native species over-consume water, which reduces water availability for native plants, wildlife, and people. Lastly, non-native trees, like eucalyptus, drop oily leaves and bark that inhibit native plant growth and impair aquatic life.

The project will enhance the existing native oak woodland, increase stream flow, and benefit habitat value. Additionally, local youth gain the opportunity to participate in environmental work through The Concerned Resource Environmental Workers (CREW) and California Conservation Corps (CCC). The project area is supported through community partners, including (City of Ojai, CREW, Green Valley Project, Pax Environmental, Channel Islands Restoration, Mark Crane Tree Service, Ojai Valley Land Conservancy, Once Upon a Watershed, and Growing Work) who have historically collaborated on several Ojai Valley restoration projects. The project is funded through the California Department of Fish and Wildlife’s Proposition 1 Watershed Grant Program.

Middle Stewart Canyon Creek is one of many community restoration projects within the Ventura River Watershed and is contiguous with previously restored sites up and down stream. To ensure reintroduction of native species, plant materials are collected and planted within the Ventura River Watershed. Plants are grown by OVLC as well as Growing Works, a plant nursery in Camarillo that provides job training, employment, and horticultural therapy to people with mental health challenges.

Before Restoration

After Restoration

Restoration of the project area will improve habitat for special-status species including southern California steelhead trout, California red-legged frog, arroyo chub, two-striped garter snake, and southwestern pond turtle. Non-native periwinkle (Vinca major), Mexican fan palm (Washingtonia robusta), and Eucalyptus (Eucalyptus spp.) will be replaced with native Coast live oak (Quercus agrifolia), California sycamore (Platanus racemose), Valley oak (Q. lobata), Black walnut (Juglans californica), and several other species of plants within the understory.

Project Schedule

Phase I – Southern Project Area

Invasive plant removal for the Southern Project Area has been completed and the area is being prepped for upcoming native planting efforts. To ensure the most locally adapted plants are reintroduced to Stewart Canyon, only plant materials collected within the Ventura River Watershed will be utilized for the project.

Native Plant Species for Spring 2021 Planting

  • Coast live oak
  • Valley oaks
  • California buckwheat (seeds)
  • Coyote brush (seeds)
  • Black walnut (seeds)
  • Creeping wild rye
  • Jimsonweed
  • Giant wild rye
  • Hummingbird sage
  • Purple sage
  • Mountain mahogany
  • Willow (cuttings)
  • Mulefat (cuttings)

Additionally, old-growth sycamores cuttings are utilized to ensure genetic integrity threatened by the introduction of the London planetree. Hybridization with non-local plant genetics can have negative consequences for generations to come. By adhering to these considerations, Stewart Canyon provides a high-quality habitat for our native plants and animals into perpetuity.

Phase II – Northern Project Area 

In November of 2021, invasive plant removal for the Northern Project Area will initiate. Non-native periwinkle (Vinca major), Mexican fan palm (Washingtonia robusta), and Eucalyptus (Eucalyptus spp.) will be removed November-December 2021.

In spring 2022, volunteer days will take place on February 12th, February 26th, March 12th, and March 26th. Volunteers will aid native planting and watering efforts of Native Coast live oak (Quercus agrifolia), California sycamore (Platanus racemose), Valley oak (Q. lobata), Black walnut (Juglans californica), and several other native species.

Project Goals:

  • Enhance an existing native oak woodland to a functioning riparian ecosystem that supports a diversity of fish, wildlife, and plant species.
  • Decrease fire hazards associated with invasive, non-native species.
  • Provide ongoing stewardship of Middle Stewart Canyon Creek and develop outreach and networking that will help to continue project funding from a variety of community-based sources.
  • Adjacent homeowner education program on runoff management, native landscaping practices, and other practices that will support the immediate and long-term health of this local riparian habitat.
  • Provide environmentally oriented jobs for local youth working for The Concerned Resource Environmental Workers (CREW) and California Conservation Corps (CCC).

 Project Schedule:  Restoration work began in October 2020 and is expected to run through March 2024:

  • Fall/Winter 2020/2021: Begin removal of eucalyptus and Mexican fan palm trees.
  • Spring 2021: Begin planting of native trees and herbaceous plants and shrubs in coordination with tree removal schedule. Community education including planting days with OVLC, and workshops by OUW on practices that support healthy riparian habitat and water flow.
  • Summer 2021: Begin regular watering schedule, as well as weeding, on a weekly to monthly basis depending on the time of year and rainfall.
  • Fall/Winter 2021/2022: Continue and finish removal of eucalyptus and Mexican fan palm trees.
  • Spring 2022: Continue planting of native trees and herbaceous plants and shrubs in coordination with tree removal schedule.

CDFW Grant Application

CDFW Grant Agreement

Middle Stewart Canyon Creek Restoration Project, Tree Removal – Request for Bids (RFB)

SPECIAL CONSIDERATIONS:

  • Data will be collected prior to restoration activities to establish a baseline for evaluating the restoration success.
  • Aquatic, Nesting Bird, and Pre-construction surveys will be conducted prior to restoration activities.
  • Native American monitoring will be conducted during any excavation activity.
  • A local volunteer effort with multiple planting days in cooperation with the Ojai Valley Land Conservancy.
  • Established native plants will be maintained by the CREW and volunteers.
  • Data collection and analysis of restoration efforts for annual and post project reporting as required by the grant.

Flexibility:  The priority is to restore the entire area, but the City has flexibility to leave invasive trees that it deems critical. Many invasive trees, especially eucalyptus, will inhibit restoration of native vegetation and can be toxic to aquatic life. It should be noted that leaving eucalyptus trees within the project area will compromise the integrity of the habitat restoration. 

  • For example, the plan is to start from the south end of the project while reaching out to adjacent residents, prioritizing restoration removal closer to the stream and providing flexibility as far from the stream as possible.

Outreach:  City staff and consulting biologist will reach out to adjacent property owners prior and during the work to assure their understanding of the project, providing a project review and contact information, and discuss potential impacts to the removal of invasive trees and other vegetation.  Additionally, the City’s webpage for this project is being enhanced to include photo renderings of before and after restoration, and a StoryMap (click here to view).  The extensive outreach that has already taken place has resulted in the following cooperation and commitments with adjacent residents:

  • Concerns with maintaining visual blocking of neighbors’:
    • Minimizing the time between tree removal and planting to assure the landscape and any visual blocking returns as fast as possible.
    • Planting on hillsides, with frequent watering, so trees gain total height as rapidly as possible.
    • Increasing the planting ratio and new plant in areas where visual blocking is a concern, as project funds or contributions allowAssuring fast growing natives are planted, such as Sycamore and Willow trees.
  • Working with the Ventura County Watershed Protection District to see what plantings will be allowed in the rip-rapped and other concreted areas.

Environmental Protections and Monitoring:

The California Department of Fish and Wildlife (CDFW) requires the following before they issue a Notice to Proceed with the work:

  • Primary Document: CDFW Approved Planting and Restoration Plan (including a plant palette with thousands of native plantings).
  • Biological Assessment
  • Streambed Alteration Permit
  • Tree Protection Plan

City staff and a consulting environmental firm with biologist and arborist will ensure that all activities are in compliance with permit conditions. A qualified biologist/arborist will conduct pre-construction surveys (3-5 days prior to tree removal), coordinate species relocations, flag sensitive resources to avoid, conduct WEAP trainings and site checks, and complete weekly/annual reporting to ensure environmental compliance with applicable permits during restoration activities. The work plan is reviewed each day before starting work, with a plan for which trees/vegetation will be removed and a review of necessary restrictions.  Then work is monitored to ensure compliance.  Qualified Native American monitors will monitor any native soil disturbance.

Invasive Resprouting Control:

  • City staff will work with Transition to Organics to implement certain non-chemical resprouting control such as solarization and cardboard covering, where feasible
  • Hand pulling of invasive plants will be maximized.
  • The use of chemical herbicides will be minimized, applied under the supervision of licensed applicators, and will only be by hand painting or spot application, where feasible.
  • Note this project is beneficial to monarch butterflies as it increases their native foraging habitat.
