The first ever species count will happen at the Wolf Lake Forest Preserve in Greater Sudbury Wednesday.
Five scientists from three Ontario universities — including Laurentian University in Sudbury — want to take a so-called head count to figure out what species rely on the old-growth red pine stand of trees.
The stand is considered the largest of its kind in the world.
Environmentalists have been clashing with the province over mining claims in the area.
Scientists say if at-risk species are found there, mining claims will automatically be defunct.
