NSF Note: This POC will only be relevant for the LTER sites. The others would likely be listed under a generic NSF POC.
For a Circular Site or Point: (note: a site with a nine nautical mile diameter is considered a point)

Elevation of Center Point in Meters: 499
Frequency of Collection:
minimum frequency would be once/year (in summer), preferably twice per year
When (time of day or season or
whatever) should data be collected? Time of day should be mid-day (10
AM-2 PM Central time). One date of
collection should be in summer (June 15-September 15), and the second should be
either spring (April 1-May 15) or fall (October 10-November 15).
Resolution needed from data
(or scale needed): less than or equal to
1m
What is the impact of not
collecting the data when requested? a
missed opportunity to study annual changes in the structural characteristics of
the riparian zone
Describe the things or phenomena to be monitored and the purpose of the monitoring. Include information about the duration needed for monitoring to be effective.
Optical characteristics of lakes, physical structure of the littoral/riparian zone, land use and land cover change
What ecosystems are present at the site?
Northern temperate lakes in glacial landscapes in forested watersheds. Oligotrophic, dystrophic and eutrophic lakes; temporary forest ponds; warm and cold streams; sphagnum-leatherleaf bog; conifer swamp; mixed deciduous and coniferous forests.
Are there management issues associated with the site?
Land use and land cover change
Riparian zone/lake interactions
Nutrient loading
Is the site designated for special management or use (e.g. long term studies, specially reserved regions)?
The site contains primary study lakes of the North Temperate Lakes LTER site. This project has been conducting long-term studies of these lakes since 1981. The surrounding terrestrial landscape is mostly contained within the Northern Highlands State Forest. More than 2500 lakes lie within the Northern Highlands lake district.
Have previous monitoring activities been done at this site? If so, are data available in digital form?
The North Temperate Lakes LTER project has collected a diverse set of long-term physical, chemical, and biological data on the primary study lakes. These data (not including the two previous years) are available in digital form on the North Temperate Lakes LTER website (lter.limnology.wisc.edu).
Describe any special characteristics of the site or the things or phenomena that are to be monitored (information that might help determine how it might be useful to monitor the things or phenomena at the site).
The site represents one of the few north temperate lakes sites with existing long-term field measurements. An area of active research is the impact of land use change on lake ecology. The riparian/littoral zones are expected to change over time, and we want to document this change on at least an annual scale.
