U.S. Fish and Wildlife Service Proposes Endangered Species Act Protection for Two Butterflies

October 23, 2013

Two butterflies, the Dakota skipper and the Poweshiek skipperling, have been proposed for protection under the Endangered Species Act due to steep population declines, according to the U.S. Fish and Wildlife Service.


The Service has proposed the Dakota skipper as a threatened species. Found in Minnesota, North Dakota, South Dakota and Canada, the Dakota skipper has experienced a dramatic decline in numbers and no longer occurs on half the sites where previously found.


The Poweshiek skipperling is proposed as endangered. This butterfly, once found in eight states and Canada, now occurs only in a few native prairie remnants in Wisconsin and Michigan, and in Manitoba, Canada. Surveys indicate that Poweshiek skipperlings are gone from nearly 90 percent of the sites where they were previously found.

An HCP planning grant was awarded to the Service's Midwest Region (including Wisconsin) to develop a Habitat Conservation Plan for Wind Energy Development. Also, the Wisconsin Department of Natural Resources was awarded a Recovery Land Acquisition grant to benefit the endangered Kirtland’s warbler, Karner blue butterfly, and associated barrens species.

The U.S. Fish and Wildlife Service today announced nearly $32 million in grants to 20 states to help advance their collaborative efforts to conserve America’s rarest species and vital habitat.


The grants, issued through the Cooperative Endangered Species Conservation Fund, will benefit numerous threatened or endangered species. The Service’s Midwest Region was awarded two grants in 2013, one in Wisconsin that will benefit the endangered Kirtland’s Warbler and Karner blue butterfly, as well as a grant to support the planning of a region-wide Habitat Conservation Plan for wind development.

The U.S. Fish and Wildlife Service will host a public open house aimed at providing information and receiving input about fish passage alternatives at Prairie du Sac Hydroelectric Dam on the Wisconsin River.  The open house will be held Monday, July 15, from 5:00 p.m. to 7:00 p.m. at the Ruth Culver Community Library, 540 Water Street, in Prairie du Sac.  Service biologist Nick Utrup will provide an overview of alternatives at 6:00 p.m.


The Service is developing an environmental assessment, in accordance with the National Environmental Policy Act, to evaluate the environmental impacts of providing a way for fish to pass upriver and downriver from the dam.   The Service will also consider how to prevent upstream passage of non-native invasive species, such as Asian carp.

June 25, 2013


A Kirtland’s warbler that hatched in Wisconsin last year and was banded before its first migration has returned to its birthplace in Adams County, providing a significant milestone in efforts to help boost populations of this federally endangered songbird, state and federal bird experts say.


“This is the first time we’ve been able to document that a bird hatched in Adams County has returned to the area,” says Kim Grveles, a Department of Natural Resources avian ecologist. It’s a very encouraging sign that Wisconsin is providing suitable and successful breeding habitat for these birds.”

Helping a Recovery Program Take Flight

Working with the Karner blue butterfly in Wisconsin


Karner Blue Butterfly

Just over 20 years ago, the Karner blue butterfly (Lycaeidis melissa samuelis) and I became fast and inseparable friends. Our relationship began in 1992, after the U.S. Fish and Wildlife Service (Service) proposed listing the butterfly as endangered under the Endangered Species Act (ESA). Luckily, I was in the right place at the right time—of the seven states where the Karner blue was known to occur, Wisconsin boasted the largest population. So when I became the Service's first Endangered Species Coordinator in Wisconsin in 1993, I also became the Karner blue butterfly Recovery Coordinator. Things haven't been the same since.
