Tanacetum huronense, also known as Lake Huron tansy, is a type of wildflower most commonly found on sand dunes around the Great Lakes. Lake Huron tansy currently requires conservation measures in some regions. [1]
Lake Huron tansy is most commonly found around the northern coasts of Lake Michigan and Lake Huron as well as the southeast coast of Lake Superior, but has also been found in Maine and from Alaska across Canada. [2] This plant lives in the sandy soil of the sand dunes and beaches of these regions. [1] The Lake Huron tansy requires sun as well as dry sandy soil to thrive. [2] However, this species can also handle waves when water levels are higher. [1]
Lake Huron tansy grows approximate 12” tall [3] from 1-3 stems. [1] If any part of the plant is crushed a very distinct odor is released, similar to the common garden tansy. [4]
Lake Huron tansy typically blooms during the months of late June through early August. The flower is a yellow “daisy type” flower, composed of many smaller flowers. The flower head is made up of disk flowers and ray flowers fill in around the outer rim of the head. [1] The flowers are typically 13-19mm in diameter. [5]
The leaves are visually lacy and hairy. [4] The structure of the leaves are bipinnately compound [5] between 23 and 26 cm long and 3 to 9 cm wide. [6]
Tanacetum huronense is currently being monitored by various states and countries. It is currently a threatened species in Michigan and endangered in Wisconsin. In addition, Lake Huron tansy is a special concern species in some Canadian provinces. [2] According to the Wisconsin DNR, this species has a very high priority for conservation due to very few natural occurrences. [6]
In Michigan, Lake Huron tansy is threatened by invasive species such as spotted knapweed and baby’s breath. In addition, this species is threatened by habitat destruction and disturbances from humans. [1]
Lake Michigan is one of the five Great Lakes of North America. It is the second-largest of the Great Lakes by volume and the third-largest by surface area, after Lake Superior and Lake Huron. To the east, its basin is conjoined with that of Lake Huron through the 3+1⁄2-mile (5.6-kilometer) wide, 295-foot deep Straits of Mackinac, giving it the same surface elevation as its easterly counterpart; the two are geologically a single lake.
Tanacetum is a genus of about 160 species of flowering plants in the aster family, Asteraceae, native to many regions of the Northern Hemisphere. They are known commonly as tansies. The name tansy can refer specifically to Tanacetum vulgare, which may be called the common tansy or garden tansy for clarity. The generic name Tanacetum means 'immortality' in Botanical Latin, since tansy was once placed between the burial sheets of the dead to repel vermin.
The Huron–Manistee National Forests are two separate national forests, the Huron National Forest and the Manistee National Forest, combined in 1945 for administration purposes and which comprise 978,906 acres (3,960 km2) of public lands, including 5,786 acres (23 km2) of wetlands, extending across the northern lower peninsula of Michigan. The Huron–Manistee National Forests provide recreation opportunities for visitors, habitat for fish and wildlife, and resources for local industry. The headquarters for the forests is in Cadillac, Michigan.
The Manistee National Forest is a national forest located in the Lower Peninsula of Michigan. It has a total area of 540,187 acres (2,190 km2). It was established in 1938, and combined with the Huron National Forest in 1945 for administrative purposes, creating the Huron-Manistee National Forests. However, they are two separate forest units, as they are not connected. The area is popular for hiking, fishing, camping, boating, snowmobiling, cross-country skiing and hunting. The North Country Trail passes through it, and connects with the 11-mile Manistee River Trail to form a 23-mile loop. The highest point in the lower peninsula, Briar Hill (1,706 ft), is located here. The Manistee National Forest is not one continuous mass, but is a "mosaic" broken by private property and towns. The headquarters for the forest is in Cadillac, Michigan.
Tansy is a perennial, herbaceous flowering plant in the genus Tanacetum in the aster family, native to temperate Europe and Asia. It has been introduced to other parts of the world, including North America, and in some areas has become invasive. It is also known as common tansy, bitter buttons, cow bitter, or golden buttons. The Latin word vulgare means "common".
Silene virginica, the fire pink, is a wildflower in the pink family, Caryophyllaceae. It is known for its distinct brilliant red flowers. Fire pink begins blooming in late spring and continuing throughout the summer. It is sometimes grown in wildflower, shade, and rock gardens.
Sand Ridge State Forest is a conservation area located in the U.S. state of Illinois. Containing 7,200 acres (2,900 ha), it is the largest state forest in Illinois. It is located in northern Mason County. The nearest town is Manito, Illinois, and the nearest numbered highway is U.S. Highway 136. It is located on a low bluff, or "sand ridge", overlooking the Illinois River, hence the name.
Iris lacustris, the dwarf lake iris, is a plant species in the genus Iris, subgenus Limniris and in the section Lophiris. It is a rhizomatous, beardless perennial plant, native to the Great Lakes region of eastern North America. It has lavender blue or violet-blue flowers, a very short stem and long fan-like green leaves. It is cultivated as an ornamental plant in temperate regions. It is closely related to Iris cristata.
Whitefish Dunes State Park is a 867-acre (351 ha) state park of Wisconsin on the eastern shore of the Door Peninsula. This day-use park preserves the most substantial sand dunes on the western shore of Lake Michigan. The remains of eight successive prehistoric Native American villages are on the National Register of Historic Places as Whitefish Dunes-Bay View Site. Cave Point County Park is an enclave inside the state park, allowing visitors free foot access to the state park by the shoreline trail connecting the parks.
Cirsium pitcheri, sometimes called Pitcher's thistle or dune thistle, is a species of thistle native to sand dune shorelines along the upper Great Lakes. It is native to Indiana, Illinois, Michigan, Wisconsin, and Ontario. It is listed by the U.S. Fish and Wildlife Service as a threatened species.

Kohler-Andrae State Park comprises two adjacent Wisconsin state parks located in the Town of Wilson, a few miles south of the city of Sheboygan. They are managed as one unit. Terry Andrae State Park, established in 1927, and John Michael Kohler State Park, established in 1966, total 988 acres (4.00 km2). The parks contain over two miles (3 km) of beaches and sand dunes along the shore of Lake Michigan, with woods and wetlands away from the water. The Black River flows through the parks.
Tanacetum camphoratum is a species of flowering plant in the aster family known by the common names camphor tansy and dune tansy. It is native to the Pacific Coast of North America from British Columbia to California, where it grows in sand dunes and other coastline habitat. This species may be known by the synonym Tanacetum douglasii and is often included in Tanacetum bipinnatum. It is a rhizomatous perennial herb with a thick, low-lying stem up to 25 centimeters long, branching to form a mass of vegetation. It is hairy, glandular, and aromatic, with a camphor scent. The leaves are up to 25 centimeters long and thick but featherlike, divided into many narrow leaflets on each side of the main rachis. Each leaflet in turn has many segments along each side, and the segments are usually divided into several small, knobby segments with folded or curled edges. The inflorescence bears up to 15 flower heads, each about a centimeter wide or slightly wider. Each head contains many yellowish disc florets and many pistillate florets around the edges. The latter may have minute ray florets. The fruit is an achene a few millimeters long which is tipped with a small pappus of toothed scales.
