The North Temperate Lakes Long-Term Ecological Research (NTL-LTER) program conducts and facilitates long term ecological research on Wisconsin lakes. Housed on both the UW-Madison campus and at Trout Lake Station, NTL is part of the larger LTER network funded by the U.S. National Science Foundation since 1981. NTL is dedicated to fostering a welcoming and supportive community where everyone is valued, treated with respect, and has the opportunity to contribute and thrive in all aspects of our research and activities. We invite you to explore our datasets and collaborate with us.
