Biological Assessment and Evaluation
Species Distribution and Occurrences within the Study Area
Lapland buttercup is broadly distributed across the arctic and boreal
regions of Alaska, Canada, Greenland, and Europe (Coffin and
Pfannmuller, 1988). The species is very rare south of Canada and has
only been identified in Minnesota and Maine. In Minnesota, ten
stations have been found, three of these in St. Louis County. This
northern, circumboreal species is known from only four US states
(Minnesota, Wisconsin, Michigan, Maine and Alaska) and all Canadian
Provinces and Greenland.

Two known locations for Ranunculus lapponicus are shown in data provided by the DNR and CNF within
the Study Area. These are located in Cedar dominated swamps in the eastern portion of the Study Area.
Risk Factors
Threats to this species include alteration of hydrology where the species is present, and stress due to
removal of forest tree canopy.
4.2.5.7 Northern bur‐reed (Sparganium glomeratum)
Northern bur‐reed is listed as DNR Special Concern, CNF RFSS and DRM Threatened.
Potential effects for this species are described in the following Guilds: Bogs and Fens and Wet Prairie,
Sedge Meadows and Emergent Wetlands.
Species Description
This species is of a genus of sedge like herbs, floating or emergent in shallow water, forming
rhizomatous colonies (Chadde, 2002). This species can be distinguished from similar species of
Sparganium by the inflorescence. Staminate flowers are borne in a single, small, terminal head. There
are three to five supra‐axillary, densely crowded, pistillate heads with all but the lowest head
overlapping (Coffin and Phannmuller, 1988).
Species Habitat
The species has been found in several locations in Lake and St. Louis Counties in shallow sphagnum bogs
and floating mats in emergent wetlands.
Species Distribution and Occurrences within the Study Area
Northern bur‐reed is a typically Eurasian species that has been found in
North America only in Alberta, Quebec, and Minnesota (Coffin and
Pfannmuller, 1988). Common in Northern Europe, this species is
uncommon in North America and is suspected to have been introduced
to the continent as North American populations are all located near
international ports. In recent years, the species has been identified and
found to be common throughout the CNF. The species is known from
only four Canadian Provinces (Newfoundland, Quebec, Saskatchewan
and Alberta) and two US states (Minnesota and Wisconsin).
