Wisconsin Lake Plants - multi source database of lake plant abundance 1930 - 2004
This data set provides sampling-point by sampling-point macrophyte data for lakes sampled by a number of agencies in Wisconsin. The relational tables in this dataset were originally used to generate plant community tables. This dataset contains detailed and recent data from approximately the 1970s onward. Sampling timing and intensity varied. Table DATSOUR contains sources of data for tables AQUAPLT2 and LAKEHAB. Table AQUAPLT2 gives an estimate of plant density at each sample point. Table MAXDEPLNG has initial lake parameters derived from data in AQUAPLT2 and LAKEHAB Table LAKEHAB contains habitat characteristics at macrophyte sampling locations. Table PLTNAME has species information for plants in tables AQUAPLT2 and LAKESPEC. Table LAKES contains information for lakes included in this dataset. Table COUNTY contains information associated with the counties where the lakes in the AQUAPLT2 dataset and the LAKESPEC dataset are located. . Sampling Frequency: varies Number of sites: 1938
This data set provides sampling-point by sampling-point macrophyte data for lakes sampled by a number of agencies in Wisconsin. Sampling timing and intensity varied. An estimate of plant density is given at each point and water depth and substrate information is available for many sampling points. The AQUAPLT2, DATSOUR, MAXDEPLNG, PLTNAME, and LAKEHAB tables are relational and were original used in a database to generate plant community tables. These relational tables contain more detailed and recent data from approximately the 1970s onwardThe LAKESPEC table contains analyzed plant community data that may have been generated from the above tables or gleaned from the literature. The LAKESPEC data contains some historical data from the 1930s and before as well as more recent data. More information on the LAKESPEC data is in Nichols, S.A. and R. A. Martin, 1990.
