Developing Tools and Partnerships to Protect Public Health and the Environment


Welcome to the newly opened Soils of Mendocino County Web Site!  Inceptisols, Ultisols, Spodosols, and other soil orders can be found within close proximity of the town of Mendocino (See pictures and descriptions of soil orders).  These soils each support unique ecosystems ranging from grasslands along the coast to mixed conifer and pygmy forests further inland.  These soils and the plant and animal communities that live on them have coevolved in response to the unique geomorphological activity of marine terraces in the region. The continental shelf in the region has experienced uplift for at least a couple million years (See picture at left).  This in combination with fluctuating ocean levels during glacial cycles has etched out a series of steps or terraces that due to uplift extend several miles inland.  So, we invite you to take a look at what this site has to offer, including:

  • A map showing the locations of a recent field trip by our group;  (You can click on the sites to get the soil description sheets for soils such as: Humic Dystrustepts, Typic Plinthohumults, and Oxiaquic Haplorthods.)
  • An argument for the preservation of soils and unique ecosystems;
  • Static maps of the Mendocino area at 24K, 100K, and 250K resolution;
  • The 12 Soil Orders; and
  • Links to Other Resources on Marine Terraces and the Mendocino Area.
