This dataset, covering the conterminous United States, Hawaii, Puerto Rico, the Virgin Islands, Guam, the major Northern Mariana Islands and Alaska, continues to grow at a rate of 50 to100 million acres annually as data are updated. The data layer is updated twice a year and these changes are reflected on the mapper and in the data downloads.
