On October 1, 2009, in Monterey, California, the Postal Service issued 44–cent Nature of America: Kelp Forest commemorative stamps in a pressure-sensitive adhesive (PSA) pane of 10, and an $8.95 Premium Stamped Postal Card Booklet of 10. The stamps were designed by Ethel Kessler of Bethesda, Maryland. This 2009 Nature of America issuance features a kelp forest off the central California coast. This is the 11th stamp pane in an educational series focusing on the beauty and complexity of major plants and animal communities in the United States. To illustrate the biodiversity of a kelp forest, artist John D. Dawson of Hilo, Hawaii, depicted more than 27 different species in his colorful acrylic painting.
