This file contains data from surveys of plant assemblages in Maine lakes and ponds. The first two data worksheets contain data from "rapid assessment" surveys conducted by Don Cameron (Maine Natural Areas Program) and others. The third data worksheet contains survey data provided by Keith Williams. The rapid assessment (RA) surveys were intended primarily to evaluate whether or not invasive plant species were present in the waterbodies. However, all plant species observed and identified during each survey were recorded and these data are included here. Data from these RA surveys are split into two data worksheets. The first data worksheet (Background data [RA]) provides information about each RA survey, along with descriptions of lake habitat, etc. The second data worksheet (Plant data [RA]) provides the plant species data. In these two worksheets, the field "Survey Number" provides a common field by which both tables may be linked if downloaded and then imported into a relational database. Data in these two worksheets were originally provided by D. Cameron to P. Vaux in 2005 for inclusion in the Maine Aquatic Biodiversity Project database. Survey data provided by Keith Williams are included in the third data worksheet (Other Surveys). Sampling effort data are not available for any of these surveys - effort may have varied among surveys.
