Treatment Plan And Educational Guide For Removing Invasive Barnyard Grass, Canada Thistle, And Cocklebur Within The Baduwa't (Mad River) Estuary, Ashley S. Turner, Alex D. Lallman

Cal Poly Humboldt Capstone Honor Roll

Our project is located at the Baduwa’t Estuary. We partnered with CalTrout to assist them with meeting one of the objectives for their Mad River (Baduwa’t) Estuary Floodplain Habitat and Public Access Enhancement Project. CalTrout partnered with the landowner, McKinleyville Community Services District, to restore 4.25 acres of the estuary. Our project focused on reducing the abundance of invasive plant species within the estuary area. The target plant species were barnyard grass, Canada thistle, and cocklebur. First, we conducted a literature review to learn the best management practices for eradicating the three target species. Then we conducted a field survey …

The Scott and Shasta rivers, Klamath River tributaries, experience spatial disparity in habitat quality in spring and summer as a result of historical and current land-use. Juvenile Coho Salmon (Oncorhynchus kisutch) born in the upper tributary reaches often rear in natal streams before migrating to sea. However, those born in the lower reaches often encounter unsuitable habitat and emigrate during their first spring to seek non-natal rearing habitats. It is assumed that these early outmigrants are population losses. This study evaluated first-summer survival, and contribution to the adult population, of non-natal rearing juveniles in the Klamath River Basin. …
