Current projects:
Annual vegetation monitoring on the Upper Mississippi River System (UMRS) was implemented in 1991 under the Long Term Resource Monitoring Program (LTRMP). An annual report was prepared for each year of sampling.
All potential users of these data are strongly encouraged to read and understand the stratified random sampling LTRMP Procedures Manual (Yin et al. 2000) that describes site selection and sampling protocols before undertaking any analysis or interpretation of the stratified random sampling data.
All potential users of these data are strongly encouraged to read and understand the vegetation monitoring section of the LTRMP Procedures Manual (Rogers and Owens 1995) that describes procedures for both ground surveys and aerial photography interpretation before undertaking any analysis or interpretation of the data. Transect data was collected form 1991 to 2000. Informal data was collected from 1991 to 1997.

Presently, the LTRMP conducts annual monitoring of vegetation using a stratified random sampling method (Yin et al. 2000) in five study reaches of the Upper Mississippi River System: Navigation Pools 4, 8, 13, and 26 on the Mississippi River; and La Grange Pool on the Illinois River. The LTRMP will continue to expand vegetation monitoring beyond these five study reaches and welcomes participation by other agencies and groups that could sample other areas using the LTRMP sampling protocol.

These data have been generated by State agencies under contract with the Department of the Interior and the Upper Midwest Environmental Sciences Center (UMESC). Although these data have been processed successfully on a computer system at the UMESC, no warranty, expressed or implied, is made regarding the accuracy or utility of the data on any other system or for general or scientific purposes, nor shall the act of distribution constitute any such warranty. However, error correction is a continuing process, and the UMESC routinely makes changes to data as errors are discovered. The file date is referred to as the release date and should be mentioned in all references to data. These data have been provided as a unit package to ensure that you receive a valid data set collected in a consistent manner. Methods, purposes, and conditions can vary dramatically among data-collecting efforts and these data should not be combined with other data sets from the UMESC or other sources unless the user fully understands the procedures and that data are comparable across sources.
