This program produces tables and maps from the USDA Forest Service's
Forest Inventory and Analysis Data Base (FIADB).
The user inputs the following information:
| 1. |
geographic area of interest (state/county retrieval or radius
retrieval) |
| 2. |
attribute of interest (timberland area, number of trees,
growing-stock volume, etc.) |
| 3. |
optional filters (for restricting the query to a specific ownership,
species, etc.) |
| 4. |
classification variables to be used for columns and rows and the web application generates the resulting table. If the user
selects County or Congressional District as the row variable a shaded
county map is generated.

National Atmospheric Deposition Program (NADP)
Since 1978, the North Central Research Station has sponsored two sites
that measure the chemistry of rain and snow. One is located at North
Central's Marcell Experimental Forest in northern Minnesota (Chippewa
National Forest), the other is located at the Wellston Field Lab west of
Cadillac, MI (Huron-Manistee National Forest). NADP is a long-term
monitoring and research data base describing the chemical climate of
America. It is the highest quality precipitation chemistry data base in
the world! Over 200 sites can be accessed through this link. The data base
is housed at the Illinois State Water Survey in Champaign, IL. They
coordinate a cooperative effort of the U. S. Forest Service along with
many other federal, state, and industry sponsors. These data are used by
the Forest Service for nutrient cycling research, administration of the
Clean Air Act in Forest Service Class I Wilderness Areas and for day to
day monitoring of rain acidity and mercury in rain. The North Central
Research Station established the first long-term monitoring site in this
program on July 3, 1978 to provide basic chemistry for ecosystem studies
and test the effectiveness of the Clean Air Act and Amendments. In 1993,
the North Central Research Station began the first international
monitoring network for mercury in precipitation with a station at Marcell,
MN, Buffalo, NY, and Champaign, IL. In 1996, the North Central Station
turned a functioning international network of 16 station over to the
Illinois State Water Survey. Today this program encompasses over 40
mercury sites in the United States and Canada. Basic studies on the fate
of mercury in the environment are carried out at the Marcell Experimental
Forest in cooperation with the University of Minnesota, and the Science
Museum of Minnesota. AT this site you will find detailed local data,
examine national and international maps of precipitation chemistry, and to
download historic data for any location.
