During the December unit on
wolf research and management each student was assigned to investigate a wolf
pack in Wisconsin by recording information from progress reports published by
the Wisconsin Department of Natural Resources in their annual and biannual wolf
reports from 1995 to 2009.
Students were encouraged to select a pack that resides
close to their “place,” for instance Vilas or OneidaCounty.This way the student will have a greater
connection to the pack of interest.
Each student’s job was to find certain details about
their pack across the years of its existence. Examples of these details are
pack size, pup count, area of territory, depredations by their pack (number of
livestock or pets killed by that wolf pack), wolf mortality, movements, and
whichever adults that were collared in that pack. If one of the wolves from the
pack dispersed and started a new pack, the student researched that pack as
well.
For most kids, the hard part is keeping track of two
different packs at the same time. For example, three students started out with
the BootjackLake
pack in western Oneida and eastern PriceCounties.
In 1996, a black colored disperser drove out the alpha male. That same year the
former alpha found another mate, and started the Wilson Flowage pack. Then, in
2003 the Wilson Flowage pack disappeared, and two years later in 2005, the BootjackLake pack went from two adults and one
pup to eight adults and three to five pups. One of the students interpreted it
as the Wilson Flowage pack had joined the BootjackLake
pack, their ancestral pack, for at least a short duration.
While working on this project, I have concluded that
wolves have an amazing history of recolonization in Wisconsin.Despite habitat that was believed to be marginal for wolves, thus
limiting the carrying capacity to 350-450 wolves in Wisconsin (Mladenoff et al. 1999), there are
currently 626-662 wolves in the state inhabiting areas that some scientists did
not believe were suitable for wolves!
Such is amazing considering the population estimate for
wolves in the early 1970’s was zero. To link to the RESA December newsletter, from which the article originally appeared, CLICK HERE
