Abstract
Woody Ryno Farms is situated in McKinleyville, Humboldt County, California. The surrounding area is a mosaic of farmland, homes, and wetlands. This project aims to gather information about the health and species composition of the wetlands on Woody Ryno Farms. A step-point method was used to collect data on species composition along 16 m transects at 2 m intervals; all plants within a 1 m radius were identified and documented. Following data collection, we used Excel to analyze data based on several factors, including transect number, plants identified to the lowest taxonomic level, and native versus invasive taxa. Statistical analysis revealed a dominance of native individuals (90%) in the understory, which was predominantly composed of California blackberry (Rubus ursinus), lady fern (Athyrium filix-femina), and skunk cabbage (Symplocarpus foetidus). Of the invasive individuals (10%), English ivy (Hedera helix) and Himalayan blackberry (Rubus armeniacus) were most dominant. Based on project data, we used ArcGIS to create a map depicting areas of high concern for invasive removal. A comprehensive restoration plan was developed for the landowner. The plan includes targeted removal of invasive species, measures to prevent Scotch broom (Cytisus scoparius) encroachment, and the establishment of a flagged trail for educational purposes. It also recommends planting native shrubs, such as thimbleberry (Rubus parviflorus) and red elderberry (Sambucus racemosa), to provide wildlife with forage and habitat. Additionally, native herbs, such as lady Fern and deer Fern (Struthiopteris spicant), will be planted to help prevent the reestablishment of invasive species in cleared areas. Mechanical and hand crew labor will be used to physically remove invasive plants, followed by pile burning for Himalayan blackberry, Scotch broom, and cotoneaster.
