Bog Namesake:
Thanks to Tim and Judy Walker of New Hope, Minnesota for their generous donation to make the preservation of this 40 acre Black Spruce and Tamarack bog possible. This bog is also named for Winterberry (Ilex verticillata), which rows here along the margin between bog and more open aspens. Winterberry is known to be a winter food source for Evening Grosbeaks, which are also featured on the main property sign along Murphy Road.

Donor Notes:
“We live in New Hope, a suburb of the twin cities, are both retired and have four children and three grandchildren. Judy is the birder and Tim enjoys getting a good photograph. We will be expanding our birding at the Sax Zim Bog beyond winter birding to warbler Wednesday’s this May. Five family members, parents, siblings and a cousin have died over the past few years. This, along with our constant observation of the destruction of habitat, drove our decision to help Friends of Sax Zim Bog purchase forty acres. The purchase of this land will preserve habitat and serve as a memorial Bog for our families. We thank Friends of Sax Zim Bog for this opportunity.”
–Tim and Judy Walker
