The Nature of America Series of self adhesive stamp sheets were released annually by the United States Postal Service from 1999 until 2010. The series of twelve sheets started with the Sonoran Desert sheet. The Pacific Coast Rain Forest sheet issued in 2000 was the second sheet in the series.
All 12 stamp sheet issues in the Nature of America Series are shown at Beyond The Perf along with design sketches.
