Disclaimer
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. Error correction is a continuing process, and UMESC corrects
data errors routinely when a correct value can be determined. UMESC does not
delete questionable data when the correct value cannot be determined, but
attempts to mark such data with an appropriate flag. Users are strongly
cautioned to check the accuracy of any data obtained and to report suspected
values to UMESC. Methods, purposes, and conditions can vary dramatically
among data-collecting efforts and these data should not be combined with other
datasets from the UMESC or other sources unless the user fully understands the
procedures and purposes used to create each set of data and can verify that
data are comparable across sources.

VEGETATION SRS ANALYSIS DATA HISTORY
Annual Vegetation SRS monitoring on the Upper Mississippi River System (UMRS)
was implemented in 1998 under the Long Term Resource Monitoring Program (LTRMP)

SUMMARY
LTRMP Vegetation Sampling Design
Currently, the LTRMP conducts annual monitoring of vegetation 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. Contact Yao Yin,

The UTM northing coordinate for the site. The coordinate is recorded from a GPS unit as soon as the
field crew arrives at the site.

UMESC derived easting Universal transverse mercator (UTM) easting coordinate for a
sampling site ( in meters) as preassigned by UMESC. Proper interpretation of this coordinate

coordinates for stratified random sampling (SRS) only. For SRS sites, this coordinate is also the initial
assignment for Coordinates east west.
UMESC DERIVED NORTHING
UMESC derived northing Universal transverse mercator (UTM) northing coordinate for a
sampling site ( in meters) as preassigned by UMESC. Proper interpretation of this coordinate
requires reference to the appropriate UTM zone (15 or 16 for LTRMP). UMESC preassigns

subsampling area. Otherwise the box is left blank.

floating leaf and emergent species by site. The box is left blank for submersed and nonrooted floating
