Aconitum noveboracense | |
Aconitum noveboracense, also known as northern blue monkshood or northern wild monkshood, is a flowering plant belonging to the buttercup family (Ranunculaceae). Members of its genus ( Aconitum ) are also known as wolfsbane. [4]
A. noveboracense is listed as a threatened species by the United States Fish and Wildlife Service. [2] [3] [5] The species can only be found in Iowa, Wisconsin, Ohio, and New York, and populations have been in decline since the 1980s. [6] [7] A narrow set of environmental conditions for growth limit the plant to these areas, so a species recovery plan has been set in place to preserve the populations in these habitats. [8] [9] [7]
Blue, helmet-shaped flowers about 1 inch (2.5cm) in length are characteristic of northern monkshood. [9] Stems may have many flowers, and range from about 1 to 4 feet (0.30 to 1.22 m) in length. [9] The leaves of A. noveboracense are broad with lobes that are coarse and toothed. [9]
Northern monkshood is a perennial and can reproduce sexually by pollination or vegetatively by producing bulbils. [6] Self fertilization is usually not a viable means for reproduction in A.noveboracense. [7] The flowers bloom between June and September and are pollinated by bumblebees. [9] The seeds are dispersed through water or gravity. [7]
Aconitum is a genus of herbaceous perennial plant that is part of the family Ranunculaceae. [10] The genus contains highly toxic alkaloids that act as cardiotoxins or neurotoxins (aconitine). [4] Aconitine may be lethal in humans in doses of only 1.5-6mg. [4] Leaves of the plant are arranged spirally and have 5-7 segments with no stipules. [4] The segments have three lobes and are toothed. The flowers of the plant are bisexual and bilaterally symmetric, and come in many colors. Most often, the petals are blue or purple, but they may also be pink, yellow, or white. [11] [4] The upper sepal of the flower is helmet shaped, and the two true petals are contained within the hood. This appearance led to the name "monkshood." [11] Northern monkshood was considered a disjunct population of Aconitum columbianum due to its morphological similarities. [12] Genetic characterization of Aconitum noveboracense demonstrates similarity to A. columbianum populations located in western North America. [12]
Most populations of Northern Monkshood plant are found in northeastern Ohio, and portions of the "Driftless Area" located in northeast Iowa and southwest Wisconsin. [7] Only seven populations of the plant can be found in the Catskill Mountains of New York State. [7]
Aconitum noveboracense is typically found on shaded or partially shaded cliffs, algific talus slopes, or on cool, streamside sites. [6] These areas have cool soil conditions, cold air drainage, or cold groundwater flowage. [7] Outflow of cool air and water from ice in underground fissures causes these conditions on algific talus slopes. These fissures are connected to sinkholes and are a conduit for the air flows. A. noveboracense seedlings are highly sensitive to their environmental conditions and thrive in soil with a high moisture content. [6] Adult plants are less sensitive to variations in environmental conditions than seedlings, and survivorship of the seedlings is reduced with decreases in temperature or moisture content. [6]
Northern monkshood is threatened by damage to its narrow habitat range. Humans may contribute to degradation through developments like the construction of roads and powerlines. [9] Scientific collection may also put A. noveboracense at risk. [9] Deer overpopulation has severely impacted the Catskill mountain populations of Northern monkshood, which are put at risk by deer herbivory. Deer and other livestock contribute to the degradation of the habitat by trampling and grazing. [9] [7] Rising temperatures due to climate change endanger the sensitive environmental conditions required by A. noveboracense. For some New York populations, drought and flooding have impacted populations found at headwater streams. [7]
In 1978, Northern monkshood was added to the U.S. List of Endangered and Threatened Wildlife and Plants. The U.S. Fish and Wildlife Service developed a species recovery plan that describes actions needed to help the plant survive. [8] A. noveboracense is not likely to become a common species even with recovery efforts, due to its specific ecological needs. Instead, the recovery plan proposes that action should be taken to protect existing populations and their habitats. [8] Government and private conservation agencies are working to preserve the habitat of northern monkshood, and some private landowners have made voluntary protection agreements. [9] The recovery plan outlined in 1978 also lists searching for new populations and further research into propagation of the plant as desired steps for its protection. [8] The established populations are being monitored and profiled for population trends. [5] [9]
Aconitum, also known as aconite, monkshood, wolfsbane, leopard's bane, devil's helmet, or blue rocket, is a genus of over 250 species of flowering plants belonging to the family Ranunculaceae. These herbaceous perennial plants are chiefly native to the mountainous parts of the Northern Hemisphere in North America, Europe, and Asia, growing in the moisture-retentive but well-draining soils of mountain meadows.
The Endangered Species Act of 1973 is the primary law in the United States for protecting and conserving imperiled species. Designed to protect critically imperiled species from extinction as a "consequence of economic growth and development untempered by adequate concern and conservation", the ESA was signed into law by President Richard Nixon on December 28, 1973. The Supreme Court of the United States described it as "the most comprehensive legislation for the preservation of endangered species enacted by any nation". The purposes of the ESA are two-fold: to prevent extinction and to recover species to the point where the law's protections are not needed. It therefore "protect[s] species and the ecosystems upon which they depend" through different mechanisms. For example, section 4 requires the agencies overseeing the Act to designate imperiled species as threatened or endangered. Section 9 prohibits unlawful 'take,' of such species, which means to "harass, harm, hunt..." Section 7 directs federal agencies to use their authorities to help conserve listed species. The Act also serves as the enacting legislation to carry out the provisions outlined in The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
Driftless Area National Wildlife Refuge is a United States National Wildlife Refuge in northeastern Iowa, southwestern Wisconsin and northwestern Illinois. It is a collection of non-contiguous parcels in the vicinity of the Upper Mississippi River National Wildlife and Fish Refuge.

Aconitum lycoctonum is a species of flowering plant in the genus Aconitum, of the family Ranunculaceae, native to much of Europe and northern Asia. It is found in lowlands to the subalpine zone, mainly in forests and shaded habitats. Along with A. napellus, A. lycoctonum is of the most common European species of the Aconitum genus. They are also grown ornamentally in gardens, thriving well in ordinary garden soil. As such, A. lycoctonum can be found in North America, especially in eastern Canada, often in old gardens or as garden escapees.
Aconitum carmichaelii is a species of flowering plant of the genus Aconitum, family Ranunculaceae. It is native to East Asia and eastern Russia. It is commonly known as Chinese aconite, Carmichael's monkshood or Chinese wolfsbane. In Mandarin Chinese, it is known as fùzǐ and as wūtóu ; while in Japanese it is named torikabuto.
An endangered species recovery plan, also known as a species recovery plan, species action plan, species conservation action, or simply recovery plan, is a document describing the current status, threats and intended methods for increasing rare and endangered species population sizes. Recovery plans act as a foundation from which to build a conservation effort to preserve animals which are under threat of extinction. More than 320 species have died out and the world is continuing a rate of 1 species becoming extinct every two years. Climate change is also linked to several issues relating to extinct species and animals' quality of life.
Platanthera yadonii, also known as Yadon's piperia or Yadon's rein orchid, is an endangered orchid endemic to a narrow range of coastal habitat in northern Monterey County, California. In 1998 this plant was designated as an endangered species by the United States government, the major threat to its survival being continuing land development from an expanding human population and associated habitat loss. One of the habitats of Yadon's piperia, the Del Monte Forest near Monterey, California, is the subject of a federal lawsuit, based upon endangerment of this organism along with several other endangered species.
Aconitum napellus, monkshood, aconite, Venus' chariot or wolfsbane, is a species of highly toxic flowering plants in the genus Aconitum of the family Ranunculaceae, native and endemic to western and central Europe. It is an herbaceous perennial plant growing to 1 m tall, with hairless stems and leaves. The leaves are rounded, 5–10 cm (2.0–3.9 in) diameter, palmately divided into five to seven deeply lobed segments. The flowers are dark purple to bluish-purple, narrow oblong helmet-shaped, 1–2 cm (0.39–0.79 in) tall. Plants native to Asia and North America formerly listed as A. napellus are now regarded as separate species. The plant is extremely poisonous in both ingestion and body contact. It is the most poisonous plant in all of Europe.
Roberts Creek State Preserve is located in rural Clayton County, Iowa, in Wagner Township, near St. Olaf, Iowa, and a few miles north of Elkader, Iowa. Roberts Creek is a tributary of the Turkey River.
The Shenandoah salamander is a small, terrestrial salamander found exclusively in Shenandoah National Park in Virginia. The Shenandoah salamander inhabits a very small range of land on just three mountain peaks. Due to the small habitat range, interspecies competition, and climate change, the population of the Shenandoah salamander is vulnerable to extinction. Mitigating human effects on the habitat of the species will be essential in attempting to preserve and grow the population.
Algific talus slopes comprise a very rare, fragile ecosystem and habitat initially believed to exist only in the Driftless Area of Minnesota, Wisconsin, Illinois, and especially, Iowa. More recently, other algific talus slopes have been identified in the Allegheny Mountains of West Virginia. It has been suggested that close comparison with similar sites worldwide may enlarge the distribution, or that the term may become restricted to the flora and fauna characteristic of these zones within the Driftless Area.
Asimina tetramera, commonly known as the four-petal pawpaw, is a rare species of small tree or perennial shrub endemic to Martin and Palm Beach Counties in the state of Florida. The species is currently listed as endangered under the Endangered Species Act and as endangered by the International Union for Conservation. The four-petal pawpaw is part of the family Annonaceae alongside other Asimina species.
