Trinity River Watershed : Plant Spotlight – July

California hazel (Corylus cornuta subsp. californica)

California hazel is a native shrub that grows in the moist shade of forest understory and riparian areas. The leaves are soft and fuzzy, and fall off during the winter (deciduous). During the winter months, the plants produce male flowers, called catkins, along with quaint red female flowers on the same plant. Once pollinated, the female flowers will very slowly develop into a pair of seeds. The seed husks are extremely bristly (like fiberglass) and have long beaks to them, giving this plant one of its common names, “beaked hazelnut”.

Hazelnuts don’t ripen until the later summer/early fall, and often, just one (or none) of each pair will make it all the way to maturity. Hazelnuts are tantalizing food stuffs for an assortment of critters, from insects, to small rodents, to birds, to large mammals. Humans are no exception – native hazelnuts roasted on the woodstove make a delicious winter treat. To harvest, however, we humans have to use our wit to outcompete the hungry critters, who will devotedly devour every hazel in sight if given the opportunity.

The historical relationship between humans and hazels is much more multi-faceted than mere consumption. Native Americans who share a range with this plant, including the Hupa, Yurok, Wintu and Chimiariko tribes have long utilized hazels in basketry and fiber-making. In the Hupa language, there is a different word for each of these applications. K’ila:jonde’ translates to ‘hazel’ or ‘hazelnut’, while tł’ohsch’il’e:n means ‘hazel brush switches’ or ‘hazel bush’. If separated from the plant, a hazel stick itself is referred to as miq’ik’itł’oy’, and the verb for twisting a hazel withe to make it flexible is k’iq’e:n.

California hazels are just one of the important characters that constitute our local flora; healthy ecosystems are comprised of a great diversity of native plant species. Stay tuned to learn more about local native plants and their ecological roles!

2023 Watershed Grantees

On June 16, The Bureau of Reclamation and the U.S. Department of Agriculture Natural Resources Conservation Service announced 11 projects totaling $6 million to be awarded as part of three Klamath Basin Salmon Restoration grant programs and 4 of the 11 aforementioned projects will be administered in the Trinity River watershed. The 4 projects selected will improve aquatic habitat by reducing fine sediment delivery, improving fish passage, and pursuing increases to tributary flows in the dry season in tributaries of the Trinity River. We congratulate the grantees and are excited to see the outcome of each project. Please read below to learn about each grantee, proposal and award amounts.

Deadwood Creek Sediment Reduction Project (CA)
Grantee: Northwest California Resource Conservation &
Development Council
Grant Amount:. . . . . . . . . . . . . . . . . . . $98,900
Matching Funds:. . . . . . . . . . . . . . . . . . $5,800
Total Project Amount:. . . . . . . . . . . . $104,700

Prevent sediment delivery to Deadwood Creek, a major
tributary to the Trinity River, to improve anadromous
salmonid habitat. The project will remove legacy mine tailings from Mill Gulch, decommission Thorne Gulch Road, install and enhance 12 rolling or critical dips, remove abandoned vehicles and debris from stream channels and floodplains, install a gate to prevent further damage and build stream enhancement features in Thorne Gulch.

Douglas City Community Services District Feasibility
Study for Fish Habitat Improvement in Trinity River
Tributaries (CA)

Grantee: Watershed Research and Training Center
Grant Amount:. . . . . . . . . . . . . . . . . . . . . . . . . . . . . $78,800
Matching Funds:. . . . . . . . . . . . . . . . . . . . . . . . . . . . $5,600

Assess the economic feasibility of creating and maintaining a community services district (CSD) to provide a stable water supply to residents in rural Douglas City (Trinity County, California) to leave water instream for improved habitat connectivity for steelhead, coho and Chinook salmon in Browns and Reading creeks, tributaries to the Trinity River. The project would assist in determining if a CSD is an economically viable option to achieve environmental and community benefits under an increasingly dry climate.

Remove a complete barrier to aquatic species including the threatened Southern Oregon/Northern California Coast coho salmon and restore fish passage to approximately 2.5 miles of cold-water habitat. The project will enable upstream fish migration for all life stages of all fish species in East Weaver Creek, tributary to the Trinity River.

Indian Creek Fish Passage Barrier Removal Feasibility
Project (CA)

Grantee: Yurok Tribe
Grant Amount:. . . . . . . . . . . . . . . . . . . . . . . . . . . . . $184,800
Matching Funds:. . . . . . . . . . . . . . . . . . . . . . . . . . . . $11,000

Total Project Amount:. . . . . . . . . . . . . . . . . . . . . $195,800
Evaluate conditions that create a barrier to anadromous
fish passage throughout a reach of Indian Creek, a tributary to the Trinity River, with a constriction point in the Indian Creek valley. The project will create a shovel-ready project to remove a significant barrier to fish passage and reopen 7.5 miles of stream and 85 acres of habitat suitable for threatened Southern Oregon/Northern California coast coho salmon, among other aquatic species.
