Management Recommendations For Jacoby Creek Land Trust’S Off-Channel Pond Site At The Kotke Ranch And Nature Preserve, Marcos Adrian Sosa Morales, Maeve Flynn, Auston Tague
Management Recommendations For Jacoby Creek Land Trust’S Off-Channel Pond Site At The Kotke Ranch And Nature Preserve, Marcos Adrian Sosa Morales, Maeve Flynn, Auston Tague

Now more than ever there is a need for conservation easements within California because of ongoing degradation, urbanization, clear cutting and loss of habitat to ecosystems due to wildfires. The Jacoby Creek Land Trust (JCLT) is in need of a restoration and conservation plan regarding constructed off-channel ponds along Jacoby Creek. One of the ponds is flourishing and supporting different types of fishes during their migration. The other pond, our project location, is struggling to meet the JCLT’s project objectives. The pond is overgrown with European grasses due to the surrounding grazing land and has yet to see the pond's …
The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler
The Effects Of Woody Vegetation Encroachment And Removal Within A Coastal Fen, Joseph Saler
Cal Poly Humboldt theses and projects
Early successional wetland habitat is being lost in temperate regions worldwide as a result of changes in disturbance regimes that allow for the establishment and dominance of woody species. In particular, this phenomenon is pronounced in fens, which harbor high numbers of rare herbaceous species that require early successional habitat. I investigated the relationship between woody vegetation encroachment and herbaceous species diversity within a Northern California coastal fen that has been undergoing encroachment by woody vegetation for ca. 80 years by recording species richness and cover data from 338 permanent plots throughout the fen. I also investigated the effect of …

Management Recommendations For Ecological Restoration On The Little River Parcel, Maya Sady Partain, Garitt Mathews
Environmental Science & Management Senior Capstones
Ecological restoration is an important aspect of land management. Data collection and ongoing monitoring help inform restoration decisions and determine their effectiveness. In this project, we followed a monitoring protocol provided by the Trinidad Coastal Land Trust to assess the 2019 status of their Little River parcel, a fifteen-acre area near the mouth of Little River in Trinidad, California. We performed a site analysis of invasive plant species and recorded their extent and location, as well as noting other observations of the ecology, topography, and biology of the site. After making our observations, we recommended land management methods woven together …
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez
Cal Poly Humboldt theses and projects
The conservation and recovery of anadromous salmonids (Oncorhynchus sp.) depend on stream restoration and protection of freshwater habitats. In-stream large wood dictates channel morphology, increases retention of terrestrial inputs such as organic matter, nutrients and sediment, and enhances the quality of fish habitat. Historic land use/land cover changes have resulted in aquatic systems devoid of large wood. Restoration by placement of large wood jams is intended to restore physical and biological processes. An important question for scientists and restoration managers, in addition to the initial effectiveness of restoration, is the persistence and fate of large wood installations. In this …
Movement, Habitat, And Home Range Of Introduced Bullfrogs (Lithobates Catesbeianus) On Mad River Gravel Ponds (Humboldt Co., Ca, Usa), With Implications For Hydro-Modification As A Method Of Management, Madeline C. Cooper
Cal Poly Humboldt theses and projects
American Bullfrogs are a non-native, invasive species in California (USA), where they are known to have deleterious effects on many native species. Carnivorous adults prey on native amphibians and fish, while herbivorous tadpoles outcompete native tadpoles for algal food resources. Bullfrogs have been successful at colonizing old tailing ponds and other pools left over from mining activities, and these relict pools are common on many rivers in California. Information on the dispersal capabilities of Bullfrogs could help predict range expansions and inform management decisions. Unfortunately, this information is lacking from both their native and invaded range. From May to August …
Juvenile Survival And Adult Return As A Function Of Freshwater Rearing Life History For Coho Salmon In The Klamath River Basin, Molly Gorman
Juvenile Survival And Adult Return As A Function Of Freshwater Rearing Life History For Coho Salmon In The Klamath River Basin, Molly Gorman
Cal Poly Humboldt theses and projects
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. …
