Aquatic Vegetation

Stratified Random Sampling

• Graphical Vegetation Database Browser: Generate graphs depicting status and trend information (e.g., percent frequency, relative abundance, distribution maps) for aquatic vegetation. The downloading of summary statistics also is available.
  
  
• Annual Update: In 2003, the format of the annual reports was changed to a Web-based annual update where all years of data are presented in each table.

• Vegetation Stratified Random Sampling (SRS) Database Browser—Download LTRMP stratified random data. Vegetation stratified random sampling (SRS) data has been collected every year starting in 1998 and was collected during the months of June through August. 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.
  

Transect Sampling

• Vegetation Transect Database Browser—Download LTRMP vegetation transect data. Vegetation transect data has been collected every year starting in 1991 to 2000, and was collected during the months of May through August (except for the LaGrange Pool which has some September data as well). 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.

Other Information

• Vegetation Informal Database Browser—Download LTRMP vegetation informal data. Vegetation informal data has been collected every year starting in 1991 to 1997. 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.
  
  
• Floodplain Forest Data—These data were collected in a survey of the floodplain forests in selected reaches along the Upper Mississippi And Illinois Rivers in summer 1994. The survey was conducted to estimate tree mortality induced by the flood of 1993.
