Endangered Species in Wisconsin In previous years, the environment was looked at as an infinite resource. People did not realize their actions had negative effects on the environment and the species it inhabited. Such negative effects was pollution, which harmed animals and their living areas more than thought possible. It wasn’t until after events started happening, that people realized the harm they were inflicting. There were and still are many endangered species from this, however organizations and laws are now involved in the stabilization of these animals and prevention techniques. There are several endangered species in Wisconsin, however the first I am going to talk about is the Lycaeides Melissa samuelis, otherwise known as the Karner blue butterfly. These butterflies are federally endangered in the USA, at eleven sites at Fort McCoy, Wisconsin (Guiney, Androw and Wilder). The samuelis butterflies, both male and female have a wingspan of about one inch, but vary in appearance. The topside of the male is a silvery dark blue with black marks. The female is a grayish brown, especially on the outer portions of the wings. The females are wings are blue on the top and have irregular bands of orange crescents inside the narrow brown boarder. The underside of both sexes is gray with a continuous band of orange crescents along the edges of both wings and with scattered black spots circled with white. The Karner blue butterfly usually has two generations, and thus two hatches, each year. In April, the first group of caterpillars hatch from eggs that were laid the previous year. The caterpillars feed only on wild lupine plant leaves. By about mid-May, the caterpillars pupate and adult butterflies emerge from their cocoon by the end of May or in early June. These adults mate, laying their eggs in June on or near wild lupine plants. The eggs hatch in about one week and the caterpillars feed for about three weeks. They then pupate and the summer's second generation of adult butterflies appears in July. These adults mate and lay eggs that will not hatch until the following spring. Their feeding habits are that they only feed on the leaves of wild lupine plant. Adults feed on the nectar of flowering plants. This restricts where they survive. The butterfly is most widespread in Wisconsin, and can be found in portions of Indiana, Michigan, Minnesota, New Hampshire, New York, and Ohio. It may also be present in Illinois. The Karner blue butterfly is endangered due to habitat loss. The range of their habitat has been lost as a result of land development and lack of natural disturbance, such as wildfire and grazing by large mammals. This helps by setting back forests and encouraging lupine and flowering plant growth. The Karner blue butterfly was federally listed as an endangered species since 1992. There is a recovery plan by The U.S. Fish and Wildlife Service that describes and prioritizes actions need to conserve and restore this species. Researchers studying the butterfly found it is best to manage this, was its habitat. Wisconsin has implemented a statewide Habitat Conservation Plan that permits human activities, such as roadside maintenance and timber harvests, in areas that support Karners but ensures that the activities are conducted in ways that conserve and protect the species and its habitat. The second endangered species in Wisconsin I am going to discuss is the Hendersonia occulta, which is also known as the Cherrystone drop snail. These terrestrial snails have a thick 6-8mm wide shell that is wider than it is high, usually reddish or yellowish in color, and lacks an opening in the center of the base of the shell. Inhabitants of small areas of algific habitat or the similar cool, moist, shaded sites of cliffs. Very little is currently known about the biology and life history of the cherrystone drop. It is usually seen between April and September, and is likely to become inactive in autumn and winter, when it probably hides in small crevices. The cherrystone drop feeds on vegetable matter, which it scrapes using a rasping ‘tongue’, or radula, that is covered in rows of hard teeth. Although many snails are hermaphroditic and are capable of self-fertilization, in the cherrystone drop individuals are either male or female. This species lays its eggs in moist locations, such as beneath leaf litter or logs. The location of the snails in soil and leaf litter at the base of the cliffs makes them vulnerable to trampling. Preservation of habitat along the Lake Michigan shoreline will be a decisive factor in the long-term status of the snails in Wisconsin. (Lynum, Amundson and Little). The third endangered species from Wisconsin is Grus Americana, also known as the whooping crane. This species is one of two crane species native to North America. An adult Whooping Crane is white with a red crown and a long, dark, pointed bill. Young Whooping Cranes are cinnamon brown. While in flight, their long necks are kept straight and their long dark legs trail behind. Adult Whooping Cranes' black wing tips are visible during flight.
They depend on large, open wetland ecosystems to eat, roost, and make their Whooping cranes were extirpated from the Midwest and are listed as federally endangered due to decrease in habitat and from being previous hunting targets. The Wisconsin DNR, along with other members of the Whooping Crane Eastern Partnership (WCEP), are working to restore an eastern migratory population of whooping cranes that migrates annually between its Wisconsin breeding grounds and its wintering habitat in the United States. This species is not actively tracked in the Natural Heritage Inventory Database, but it could be tracked in the future if there is further evidence of its decline (King, Espenshade and Kirkpatrick-Wahl).
The fourth endangered species is the Iris lacutris, also known as the Dwarf Lake Iris. The Dward lake iris is a miniature iris with deep blue flowers. However, lilac or white flowers can be found. Their leaves are flattened, sword-like, and arranged in fan-shape clusters. The Dward lake iris only grows around the Great Lakes and occurs near the northern showers of lakes in Michigan, Wisconsin, and Ontario, Canada. Their habitat is cool, moist lakeshore air. Dwarf lake iris is found on sand or in thin soil over limestone-rich gravel or bedrock. Habitat is along old beach ridges or behind open dunes. Changing water levels can open new habitat for the plants.
The Dwarf lake iris is endangered because of habitat loss and degradation. Their habitat has been greatly reduced due to shoreline development. Residential and vacation homes, road-widening, chemical spraying and salting, and off-road vehicle use are all causes of disturbance and destruction of their habitat. Collection is also a problem. The Dwarf lake iris has been offered for sale commercially. Collection from wild populations affects the species and is now a violation of State and Federal laws. Picking the flowers often uproots the plants and prevents seed from forming. Dwarf lake iris was added to the U.S. List of Endangered and Threatened Wildlife and Plants in 1988. The U.S. Fish and Wildlife Service is in the process of developing a recovery plan that describes actions needed to help this plant survive. Dwarf lake iris populations have been monitored to determine long-term population trends and to better understand habitat and reproductive requirements. Genetic studies have been conducted to better explain population structure and differences between populations. A variety of government and private conservation agencies are working to preserve the dwarf lake iris and its habitat. Voluntary protection agreements have also been made with some private landowners (Mitchell).
The last Wisconsin endanger species I am going to talk about is the gray wolf. The gray wolf’s head is relatively large, with broad cheeks below the eyes. Face markings are well blended, lacking distinguishable borders. Well furred erect ears rounded. Light colored slanted eyes, ranging from amber to yellow. They are normally rusty brown with black tipped hair. Wolves were once common throughout all of North America but were killed in most areas of the United States by the mid 1930s. Today their range has been reduced to Canada and the following portions of the United States: Alaska, Idaho, Michigan, Minnesota, Montana, Wisconsin and Wyoming.
The most common cause of death for wolves is conflict with people over livestock losses. Wolves that do prey on them are often killed to protect the livestock. Environmental organizations are working to develop non-lethal methods to reduce the chances of a wolf attacking livestock. These methods include fencing livestock, lighting, alarm systems and removing dead or dying livestock that may attract carnivores like wolves. Another serious threat is human development into wolf territory, which leads to habitat loss for wolves and their prey species. Overall, the greatest threat to wolves is people's fear and misunderstanding about the species.

Endangered Species

...Endangered Species Think back to the first time you went to the zoo. Do you remember the excitement you felt when you got your first glimpse of a tiger? Or maybe your favorite animal was an elephant. These species and many others are in danger of becoming extinct. I’m going to explain to you the process to get a species listed as endangered and the protective measures taken to help them recover. I’ll also talk about the success rate of these efforts. The first step to protecting a threatened species is to get them listed. The process to have a species added to the list can take up to a year. Species are listed by 2 classifications, threatened or endangered. A threatened species is a species that could become endangered in the near future without proper protection. An endangered species is a species that could become extinct. To start the process someone must first file a petition or conduct a survey of the species. Anyone can file a petition providing there is enough biological evidence to warrant further investigation. Members of the U.S. Fish and Wildlife Services or the National Marine Fisheries Service complete the surveys. Several factors help determine if a species is in need of protection. A few of those factors are: Changes in habitat, over utilization due to commercial and recreational purposes, disease or predation, and inadequate regulatory Laws. Within 90 days of receiving the petition or survey they must decide if further investigation is warranted. If it...

...environmental law that I choose is Endangered Species Act. This Act was passed in 1973, to protect the extinction of or threatened species. Before I go any further let me define the difference between extinct and threatened species; • Extinction is the process by which a species die out, this means that all genetic buildup of that species is gone forever. Extinction can be the cause of Natural disaster, from human activities. • Threatened species are living organism that can become endangered in our nearby future. Endangered species represent the living species of plants and animals. That have become scarce, this means that they are in danger of becoming extinct. When an endangered species becomes extinct, this can interrupt the food chain or web. This will interrupts the production of new or improve medicine, we would loss that animal species forever because there is no genetic evidence left of that species. All this would be affected by the extinction of a species. The goal of the Endangered Species Act (ESA) of 1973 is to prevent extinction from happening. ESA was signed by President Nixon, The extinction of animals and plant species was brought about by Rachel Carson who wrote a book called Silent Spring (1962). Rachel warned about destroying wildlife with DDT in our environment. This is what prompted the enactment of the Endangered Species Preservation Act of (1966). This Act was made to protect nature species that were on the brink of extinction...

Because of its lack of natural defenses and the introduction of natural predators the Dodos population rapidly declined. Many Steps could have been taken in order to prevent the extinction of the Dodo Bird. The settlers could have tried to settle far enough so they could avoid interference with the Dodo Bird. Since much of the Dodos habitat was destroyed the settlers could have attempted to restore it to a near natural condition. Once the humans realized that the Dodos population was decreasing they could have tried to save it by raising them in captivate.

Endangered Species Act

...Helmke Business Public Policy Endangered Species Act Extinctions have occurred throughout our planet's natural history. Some species develop as others die out, making space in the ecosystem for those best suited to any given habitat's natural conditions. Long before human beings arrived, fossil records show that populations of animals evolved, thrived, declined, and became extinct. However, the rate of extinctions in the late twentieth and early twenty-first centuries drastically increased to an estimated 100 to 1,000 times the normal expected rate of extinction. The majority of these accelerated extinctions can be directly traced to mankind's impact upon the natural environment in the form of hunting, fishing, agriculture, development, pollution, habitat encroachment, disease, and global climate change. Due to the increasing number of endangered species, as well as, species becoming extinct, the United States Congress decided to take action. Congress passed the Endangered Species Preservation Act in 1966, providing a means for listing native animal species as endangered and giving them limited protection. The Departments of Interior, Agriculture, and Defense were to seek to protect listed species, and, insofar as consistent with their primary purposes, preserve the habitats of such species. The Act also authorized the Service to acquire land as habitat for endangered species. In 1969, Congress amended the Act to provide additional protection to species in danger of “worldwide extinction”...

Endangered Species

...Endangered Species: Student’s Name: Instructor’s Name: Course: Institution: Date: This statement that "Eventually, all species become extinct" is true because life and death forms part of this universe that we live in, the earth. Anything that is born at one time it is going to die. In the same way, any species that is in existence is going to get extinct. But it does not mean that we need to forget our endangered species and let them get extinct.  For example, every human being who was born is soon going to die. That means your relatives and friends, also someday are going to die. If supposedly it happens that any of your relatives or friends meet with an unexpected accident or is admitted to hospital because of a disease then you will try to help save them. Everyone knows that one day they are going to die but you won't let them die so soon. You would want them to stay longer with you.  The same case applies for other species. Every species is going to get extinct at some time in the future. But as we want relatives and those people who are close to us like friends to stay longer, the same thing also should be done to other species.  With the global warming and climate changes issues that have not been solved, organisms are endangered since their habitats are being interfered with. Resources such as water and air quality are being polluted at a very faster rate than the conservation measures taken to save them. Water is one of the main sources of conflicts in most parts of...

Poaching of Endangered Species

...Poaching of Endangered Species “The main reason for animals endangered is the uncontrolled human activity.” This quote was stated on a website called Animal Port. There are many reasons why this statement is true, one of them are poaching. Poaching occurs out of greed to make money. Although there are several laws to protect certain animals, this is a horrible act to any animal. Especially for the animals that are already endangered. Poachers minimizing these animal’s numbers for their own pleasure is not good. People who are against poaching should do what they can to stop this act from escalating, or there will not be any balance on this world. Animals are being killed every day from illegal hunting or capturing, that is called poaching; it’s getting worse and worse in certain places and we should do whatever we can to try and stop it. Poaching happens all around the world. Mainly in parts of the world where there is more game to hunt and a lot of money involved. A social science graduate from Makerere University Kampala in Uganda named Peter Galyak Magellan said that humans have been hunting for survival for a long time now and not because of pleasure. He stated “While primitive humans relied largely upon hunting for food, the agricultural revolution (approximately 10,000 years ago) reduced the need for survival hunting in most parts of the world. Hunting has continued, however, for several reasons, and poaching remains a possibility wherever hunting is...

Endangered Species Act of 1973

...The Endangered Species Act The second half of the twentieth century was a time of the greatest advancements in environmental awareness in history. It was during this time that people began to realize there impact on the environment. People began to realize that something must be done to stop the negative impacts on their surroundings which caused the environmental movement to be born. One of the most important factors that resulted from this has been the protection of endangered species. Many actions have been taken to ensure the protection of endangered species including two major policies: CITES and the Endangered Species Act.   In 1966, Congress passed the Endangered Species Preservation Act, this provided limited protection to a list of native animal species. The Departments of Agriculture, Interior and Defense were responsible for the protection of these species and the preservation of their habitats. This act also gave land to the U.S. Fish and Wildlife Service to help maintain these natural habitats. The Endangered species act was amended in 1969 because more protection was needed. With the threat of worldwide extinction, the amendment called for an international meeting and changed the name to the Endangered Species Conservation Act. Several years later, in 1973, the United States and twenty-three other nations signed an international act called CITES or the Convention on International Trade in Endangered Species of Flora and Fauna. CITES monitors...

Facts About Endangered Species

...1. An endangered species is one whose numbers are so small that it is at risk of extinction. 2. A threatened species is one that is vulnerable of becoming endangered in the near future. 3. In January 2013, the Fish and Wildlife Services reported 2,054 species worldwide that are endangered or threatened. 1,436 exist in the U.S. alone. 4. A species is declared extinct after many years of not being spotted. Because it takes so long to define an entire species as extinct, it is probable that there are many species already gone that we are unaware of. 5. A species is defined as endangered or threatened when it is compared against these five factors: * Damage to or destruction of its habitat * Overuse of the species for educational, recreational, or entertainment purposes * Disease or predation of the species * Lack of protection * Natural or manmade hazards to the continued life of the species 6. The Endangered Species Act of 1973 (ESA) protects registered endangered species by removing them from the “take” list, which makes it unlawful for a person to shoot, harm, capture, trap, or attempt any such actions to the species. 7. Ultimately, the ESA strives to recover species from the endangered list by restoring their ecological health until they no longer need protection. 8. Factors that threaten the earth’s creatures include deforestation, bycatch (the unintentional capturing of sea creatures during fishing), water scarcity...

Endangered Species

...Endangered Species Biological diversity, or biodiversity for short, refers to the variety of life across all levels of biological organizations, including the diversity of species (Withgott & Laposata, 2012, p. 49). Biodiversity at all levels is being lost to human impact, irretrievably when species become extinct. Once vanished, a species can never return. The International Union for the Conservation of Nature and Natural Resources (IUCN) Global Species Program along with the Species Survival Commission (SSC) and partners, such as the World Association of Zoos and Aquariums (WAZA), assess the status of species on a global scale for the IUCN Red List in an effort to underline possible extinction, thereby encourage their conservation (IUCN, 2014). All assessments or reassessments for publication on the IUCN Red List must use categories, such as Endangered (EN) and criteria (e.g., Continuing decline in EOO, AOO, habitat, locations or subpopulations, or mature individuals and/or Extreme fluctuation in EOO, AOO, locations or subpopulations, or mature individuals) as adopted by the IUCN Council (IUCN, 2014). In 2012, the Atrichornis clamosus (also known as Noisy Scrub-bird, Western Scrubird) was uplisted to Endangered (EN) on the IUCN Red List of Threatened Species. In questioning why, large lighting-induced fires and other small-scale unexplained events further declined population size and habitat quality on the south coast of Western Australia .

...are all melting. Our primary focus is on polar bears as they rely on masses of ice to rest after hunting for food. With the emergence of warmer climate, the areas of ice are diminishing leaving polar bears swimming for even longer until they drown from exhaustion. A federal regulation was passed in May of 2008 to protect the polar bear species from extinction by adding them to the endangered list. This should be a wake-up call to every individual living on the planet Earth as it is time to take responsibility for our actions and start making serious changes. Continued decrease of sea ice levels is expected in the future which affects the entire span of polar bears which reclassifies their status as threatened and endangered. The initial process began with a 12-Month Petition Finding and Proposed Rule during the year 2007. Polar bears are considered threatened with critical habitat under The Endangered Species Act of 1973. According to the Act: “Through Federal action and by encouraging the establishment of State programs, The Endangered Species Act of 1973 provided for the conservation of ecosystems upon which threatened and endangered species of fish, wildlife, and plants depend on.” (FWS, para. 1). Comments from the public were encouraged and were to be received by April 9, 2007,...
