In Contra Costa County's Sacramento–San Joaquin River Delta, the Palm-Orwood Tract is a landscape where agriculture and habitat conservation exist side by side. These low-lying islands are dominated by productive farmland, with crops including corn, alfalfa, wheat, almonds and walnuts, alongside areas used for cattle grazing.

Within this working landscape, a designated mitigation site is being stewarded to preserve and develop cottonwood-willow riparian forest. The forest compensates for riparian habitat impacted by a construction project, creating a long-term responsibility to maintain its ecological value.

CCRCD EcoStewards work on the ground to help that forest thrive. Their efforts focus on maintaining existing trees, managing invasive plants and establishing new layers of native vegetation. Rather than treating restoration as a one-time planting project, the team approaches Palm-Orwood as a living system that needs continued attention as it grows.

A healthy forest depends on protecting the trees already growing there, not just planting new ones. At Palm-Orwood, mature cottonwoods and willows form the foundation of the riparian forest, providing shade, habitat structure and the beginnings of a canopy that future generations of plants and wildlife can depend on.

EcoStewards help maintain this foundation by clearing fallen woody debris and managing vegetation around existing trees. Using chainsaws and other field tools where appropriate, they remove accumulated branches that need to be cleared while working carefully around living vegetation and naturally regenerating saplings.

This work requires distinguishing between material that should be removed and growth that should be protected. Young trees may be easy to overlook among surrounding vegetation, yet they are essential to the forest's future. By caring for established trees and encouraging natural regeneration, EcoStewards help preserve the structure of the forest while preparing it for continued growth.

Invasive plants can gradually change a forest by competing with native species for space, sunlight and other resources. At Palm-Orwood, EcoStewards manage Himalayan blackberry, Johnson grass, prickly lettuce and other unwanted vegetation to help native plants establish and thrive.

This work involves more than clearing visible growth. Invasive species may return after treatment, so crews must revisit areas, recognize new growth and adjust their approach over time. Meanwhile, native plants and naturally seeded trees need to be protected from accidental damage during maintenance.

Careful vegetation management creates opportunities for a more diverse forest understory and helps young plants receive the light and space they need. It also supports the broader goal of maintaining the site's intended riparian habitat over the long term.

For EcoStewards, invasive plant management is an ongoing part of forest care. Each treatment helps reduce competition and gives native vegetation a better chance to become established, strengthening the foundation for a resilient forest.

A resilient forest is made up of more than tall trees. Its understory, midstory and canopy each contribute to the structure and diversity that allow a riparian ecosystem to develop. At Palm-Orwood, EcoStewards are building these layers in stages, giving the forest a stronger foundation for the decades ahead.

The understory has been planted with native sedges and rushes, including various Carex and Juncus species. These plantings have thrived over approximately the past year and a half, allowing the team to begin focusing on the midstory.

Planned midstory species include mugwort, elderberry and buttonbush, which will add variety between the low-growing vegetation and taller trees. Each layer contributes different forms of cover and habitat, creating a more complex plant community than a forest dominated by trees alone.

By planning plantings together, EcoStewards are helping establish a forest that can mature as a connected ecosystem rather than a collection of individual plants.

The forest canopy visible today will not last forever without a new generation of trees ready to replace aging growth. At Palm-Orwood, EcoStewards are planning ahead by planting trees and protecting naturally seeded saplings that can eventually become part of the mature canopy.

This work takes patience. Young trees may need years or decades to reach the size and structure of established cottonwoods and willows. In the meantime, competing vegetation must be managed, and developing plants need room to grow.

EcoStewards combine intentional planting with natural regeneration, recognizing that both approaches can contribute to the forest's future. Clearing vegetation around promising saplings helps reduce competition and gives them a better chance to survive. Additional plantings help support the long-term goal of maintaining a healthy, continuous canopy.

The result will not be immediate. Forest stewardship is an investment measured in years, with today's decisions shaping the habitat and landscape that future generations will inherit.

Working within a riparian forest presents challenges that change with the season and the needs of the site. At Palm-Orwood, EcoStewards must balance invasive plant control, debris removal, new planting and protection of existing vegetation—all while keeping the long-term health of the forest in view.

Fallen branches can require chainsaws and careful handling, while invasive plants may grow among the native species the team is trying to protect. Young saplings can be difficult to distinguish within dense vegetation, and newly planted sedges, rushes and shrubs need time to establish before the next stage of planting can succeed.

The forest also follows its own pace. Planting plans must respond to how vegetation performs in actual field conditions rather than relying on a fixed timeline. EcoStewards observe which species thrive, identify areas needing additional attention and adapt their work accordingly.

These challenges make stewardship an ongoing process of practical problem-solving, careful observation and patience.

The future of Palm-Orwood depends on maintaining a healthy riparian forest long after individual planting seasons are over. CCRCD EcoStewards are working toward that future by caring for established cottonwoods and willows, managing invasive species, expanding native understory and midstory vegetation, and preparing the next generation of trees.

As the planted sedges and rushes continue to grow, the addition of shrubs and new trees will help create a more layered forest. Over time, these plant communities can provide a broader range of habitat and help sustain the site's intended ecological function.

Because Palm-Orwood is a mitigation site, long-term stewardship is especially important. The goal is not simply to establish vegetation today, but to maintain the riparian forest as a functioning habitat for decades to come.

Every cleared patch of invasive growth, protected sapling and successful planting contributes to that vision. The work may be gradual, but its purpose is lasting: helping ensure that the forest continues to grow, mature and support life into the future.
