Long-Term Ecological Research (LTER)/NTL005: Aquatic Macroflora Composition and Biomass in Trout Lake, WisconsinEntry ID: LTER_NTL005
Abstract: LTER - Long-Term Ecological Research Program/North Temperate Lakes (NTL)
LTER/NTL005 [Summary adapted from the LTER Core Data Set Catalog]:
These data were collected to document and characterize the submersed
macroflora of Trout Lake to evaluate the long-term stability of this
component and to interface with investigations of other compartments
of the ecosystem. Four sites along the shoreline ... of Trout Lake have
been sampled annually in August along permanent line transects.
Parameters include biomass per m2 for individual species at three
depths and frequency data by species by depth along the transect.
This information will be used to determine the annual variability of
the sub-mersed macroflora and to provide information on the effects of
the invasion of an introduced crayfish. In addition, macrophyte
surveys were conducted on Sparkling, Crystal, and Trout lakes during
1981 and on Weber (Firefly Lake) during 1984. Species lists and maps
of the macrophyte distributions were prepared. In Trout, Crystal, and
Weber lakes, biomass per species, total crop, and relative frequency
The North Temperate Lakes (NTL) site is affiliated with the Center for
Limnology at the University of Wisconsin, Madison. The NTL site
focuses its research on north temperate lake ecosystems in the
Northern Highland Lakes District of Wisconsin. The Northern Highland
Lakes District, has an area of approximately 10,000 sq. km. and has
one of the highest concentrations of lakes in the world. Lakes range
in size from 0.1 to 1,500 ha, in depth from 1 to 33 m, and in
fertility from oligotrophic to eutrophic. Other representative
limnological conditions include: rainwater dominated, groundwater
dominated and drainage lakes; dystrophic lakes; lakes with varved
sediments, winterkill lakes, temporary and permanent forest ponds, and
reservoirs. Lakes are influenced by strong seasonality and are usually
ice covered from late November to late April. Lakes within the
Northern Highland exhibit near-natural water quality conditions.
Nearly 80% of the land area and two-thirds of the lake frontage are
