Phenology Study

With guidance and direction from tribal knowledge bearers, the Climate Change Program is conducting a phenology study of treaty harvested plant species in the Ceded Territories. The study sites are in Northern Wisconsin, with one in the Penokee Range and the other in the Chequamegon-Nicolet National Forest.


Long-term monitoring of phenological changes – cyclic natural phenomena such as the budding of plants, emergence of insects, migration of birds, thawing of lake ice – can be useful indicators of environmental changes associated with climate impacts. The overall goal of the study is to gather baseline phenological data on numerous plant species harvested by the Anishinaabeg in the Great Lakes Region.


The data will be used to gain a better understanding of how possible changes to the phenology in some species might impact the locations and timing of traditional harvesting. The assessment will depend on the gathering of traditional ecological knowledge (TEK) from GLIFWC member tribes and the thorough examination of potential regional climate change impacts.


GLIFWC wants to hear about what you’ve been seeing. GLIFWC climate change staff are collecting phenological observations from around the Ceded Territories.
