< MN 2. Cedar Creek Natural History Area. Acreage: 5400 estimated. 



O 



C/3 Location: Anoka-Isanti counties; Isanti Quadrangle; 40 miles N of Minneapolis; 



W reached via Rt. 65 and County Rd. 24. 



= Description: Biological research area of the University of Minnesota, it includes 



a variety of natural undisturbed environments such as Fish Lake, Beckman 

 Lake, Cedar Creek Bog Lake, and the surrounding Cedar Creek Bog. Cedar 

 Creek and its extensive swampy complex run north and south through the area. 

 This is a truly outstanding mosaic of wetlands, where tamarack, white cedar, 

 and black spruce are especially conspicuous — a southern outpost of boreal 

 vegetation. The upland areas include prairie, oak savannah, northern hardwood, 

 red pine, and jack pine stands as well as old fields on the Anoka sand plain. 

 These are being maintained by prescribed burning.

 over 40 research papers relating to Cedar Creek Natural History Area, Anoka 

 and Isanti counties. Among these are the classic studies of R. L. Lindemann on 

 Cedar Creek Bog. 



Encroachments: Access by permit for research or educational purposes. The 

 area is patrolled and unauthorized trespass is rare. Final acquisition program is 

 now underway. Threat of a major SST airport to the north does not seem acute 

 at present.
