Compiled by Gordon Leppig and Andrea Pickart in 2018, A Photographic Guide to Plants of Humboldt Bay Dunes and Wetlands, provides a valuable and visually exceptional collection of native and invasive plants found in the area by family and genus. The plant guide and pictures are available online and free to use; however, the authors respectfully request they are appropriately credited.
