Data collected and managed by Forest Service programs is available in a map service and two downloadable file formats – in a shape file and an ESRI file geodatabase.
Metadata is available that describes the content, source, and currency of the data.
You can filter the list by the topic categories in the menu at the left to help you find information you are interested in.
You can view the feature classes in a single dataset by clicking on the name of the parent dataset at the bottom of the abstract.
Requests for KML/KMZ output
The Enterprise Data Warehouse Team tested exporting out to KML/KMZ files as a deliverable and due to the complexity and size of the datasets this has been unsuccessful.
To obtain a KML file for any EDW dataset, go to the Geospatial Data Discovery Tool and search for the dataset. An option to download to KML is available from that website.

Active Periodical Cicada Broods of the United States
Active Periodical Cicada Broods of the United States. The periodical cicada emerges in massive groups once every 13 or 17 years and is completely unique to North America. There are 15 of these mass groups, called broods, of periodical cicadas in the United States. This county-based data, complied by USFS Northern Research Station entomologist Andrew Liebhold, depict where and when the different broods of periodical cicadas are likely to emerge in the US through 2030. The data was compiled for the publication by Koenig, et. al. (2011) using data from the following historic periodical cicada publications: Marlatt, C. L. 1907. The periodical cicada. Bulletin of the USDA Bureau of Entomology 71:1-181. Simon, C. 1988. Evolution of 13- and 17-year periodical cicadas (Homoptera: Cicadidae). Bulletin of the Entomological Society of America 34:163-176.
Mapping the geographic extent of a periodic cicada brood is useful to help the public understand the cyclic nature of the emergence and the relationships with other broods. This data can be "mashed up" or combined with other data for research purposes or to create public awareness. The Brood tabular information was designed to be joined to County boundaries and to create map services for the public.
