Abstract
Our study applies Geographic Information Systems (GIS) and field-based data collection to map and assess a degraded fixed dune grassland parcel in Humboldt County, CA. Our project supports restoration planning led by Friends of the Dunes by identifying site features, habitat composition, and disturbance patterns at the site. Using GPS surveys, aerial imagery, and ArcGIS Pro, we mapped infrastructure, cement footprints, debris piles, vegetation types, and habitat boundaries. We mapped infrastructure such as concrete foundations and debris, which contribute to ongoing ecological degradation and the presence of invasive species. In addition, our spatial analysis highlights variability in disturbance. From this information, we can surmise that restoration will require a phased, site-specific approach. Overall, our findings demonstrate how GIS-based habitat mapping can guide cost estimation, prioritize restoration efforts, and support long-term monitoring. Friends of the Dunes can prioritize protecting intact habitat patches while removing infrastructure and invasive species, as this will be critical to improving biodiversity and ecosystem function. Our study underscores the value of integrating spatial data into restoration planning to enhance resilience and inform adaptive management in coastal dune ecosystems.
