Summary of Observations: Small grove of trees, primarily Western Red Cedar (Thuja plicata), Douglas Fir (Pseudotsuga menziesii), Western Hemlock (Tsuga heterophylla), and Bigleaf Maple (Acer macrophyllum). Abundant English Ivy (Hedera helix) groundcover. Some Dull Oregon Grape (Mahonia nervosa), English Holly (Ilex aquifolium) and Bay Laurel (Laurus nobilis) on lower level of forest stand as well (though less abundant). Also observed over twelve heron nests, and a pair mating. I am interested in learning more about the mating habits of herons, and in monitoring the nests throughout the Spring.
