Foreword

The data were collected in a survey of the floodplain forests in selected reaches along the Upper Mississippi and Illinois Rivers conducted in summer 1994. The survey was conducted to estimate tree mortality induced by the Flood of 1993.

Special Attention

In the Long Term Resource Monitoring Program procedures manual, trees are defined as woody stems (excluding vines) 10 cm or greater diameter at breast height (DBH) and saplings are defined as woody stems (excluding vines) 2.5 to 9.9 cm DBH. These definitions were adapted when data were collected in Pools 4, 8, 13, 17, 22, and 26, and the Open River along the Upper Mississippi River. Because of an error made by the field crew, these definitions were altered when data were collected in the Havana reach of the Illinois River. At Havana, trees were defined as woody stems (excluding vines) that were at least 10 cm in diameter and whose crown were in the canopy layer; saplings were defined as woody stems (excluding vines) that were in the understory but were 2.5 cm or greater DBH.
