Recovery Plan Critique : Santa Catalina Island Fox

Darwin's fox is considered critically endangered because of their small known population of 250 mature individuals as well as their restricted distribution.[28] On the Chilean mainland, the population is limited to Nahuelbuta National Park and the surrounding Valdivian rainforest.[28] Similarly on Chiloé Island, their population is limited to the forests that extend from the southernmost to the northwestern most part of the island.[28] Though the Nahuelbuta National Park is protected, 90% of the species live on Chiloé Island.[29] A major problem the species faces, therefore, is their dwindling, limited habitat due to the cutting and burning of the unprotected forests.[28] Because of deforestation, the Darwin's fox habitat is shrinking, allowing

The red wolf is listed as endangered under the U. S. Endangered Species Act (ESA) (United States Public Law No. 93-205; United States Code Title 16 Section 1531 et seq.). Wild red wolves inhabiting the north eastern North Carolina (NENC), USA recovery area and a single island propagation site (St. Vincent NWR, Florida) are designated as experimental non-essential populations under Section 10(j) of the ESA. The IUCN Red List of Threatened Species lists the red wolf’s status as critically endangered.

Historical levels of the Southern Resident Orca population are currently estimated to have been as high as 200 (Fisheries.noaa.gov, 2015). The population as of 31st December 2015 was calculated at just 84 individuals (Center for Whale Research, 2015). There is limited data on the population before the mid 70’s so it is unknown what the population pattern looked like prior to this. Appendix A shows a graph documenting the population data found by a census started in 1974, as well as modelled data from 1960 to 1974. The graph starts with a low population, possibly explained by the frequent capture of live animals for marine parks (National Oceanic and Atmospheric Administration, 2014, p. 3). After this period the graph shows fluctuations in the population, then a steady growth resulting in a peak in 1995, then a sharp decline – almost 20% until 2001. This fast decline is what prompted governments to first list the population a threatened (United States Environmental Agency, 2014). The population has remained stable in the following years but now has an endangered status (Fisheries.noaa.gov, 2015).

The subspecies was also listed as a highest priority “Species of Special Concern” by the State of California (USFWS, 1998). There are many factors that play into why the Point Arena mountain beaver is classified as endangered. In addition to their low reproductive rate, according to USFWS (1998), the vulnerability of the mountain beaver results from two reasons: 1) few populations with extremely limited distribution; and 2) the number of individual populations are low. Habitat loss and fragmentation is another concern for the Point Arena mountain beaver, any disaster, natural or manmade, has the potential to impact the subspecies (USFWS, 1998). These threats include, elimination or degradation from land development, livestock grazing, transportation and utility corridors, invasion of alien plant species, and timber harvest (USFWS, 1998). Additional threats to the subspecies include, predation by feral animals and household pets, poisoning, human caused disturbances, clumped and fragmented distribution, vulnerability to localized catastrophic events, like fires, storms, landslides, flooding, prolonged drought, and/or disease, and most notably genetic isolation and drift (USFWS,

According to Clifford et al. , The total population for the species in 1994 was approximately 6,000 adults but current population size is less than half that, and island foxes have declined by over 90% on four of six islands (p. 442). By 1995 ecological monitoring on San Miguel and Santa Cruz Islands in the national park had detected rapid and alarming declines in the populations of island foxes there Faced with the imminent extinction of three island fox subspecies, NPS convened ad hoc recovery team in 1999 to assess the status on the northern Channel Islands and to recommend emergency recovery actions. The team, comprising experts in canid conservation, endangered species management, and raptor research and management, concluded that island foxes were rapidly declining toward extinction on the northern Channel Islands. National Park began emergency recovery actions in 1999, with the objectives being to remove the primary mortality factor now affecting island foxes, and to recover island fox populations to viable levels through captive breeding.

This is supported by in passage, “ Only 3 wolves left on Isle Royale,” it is stated that, “Vucetich and his colleague at Michigan Tech, Rolf Peterson, both support a "genetic rescue" of the island's wolf population — bringing in wolves from elsewhere to bolster island wolves and help facilitate breeding.” But this isn't true by the evidence that i have provided that species die off by natural selection and that federal designated land is a place that we are proud of not intervening with and it should stay that way this disprove many people

The United States Fish and Wildlife Service are considering removing the gray wolf from the endangered species list once Idaho, Montana, and Wyoming have enough wolves to be deemed sufficient to continue to expand the wolf population, requiring only that each of these three states have a management plan in effect to prevent the gray wolf from becoming endangered again. With the current attitude of the governments in these states, the wolf should not lose their federal support under the Endangered Species Act as it would merely serve to cause the wolves to become endangered once again, or at best, held to the absolute minimum population that the states can pass off as “viable, self-sustaining populations”

Through the years, there has been an ongoing argument on whether or not the reintroduction of the Mexican Gray Wolves will benefit or destroy wildlife. The articles show that Mexican Gray wolves will benefit due to the reintroduction, and help the local surrounding lands. Because wolves are so miss understood, people assume the worst. Wolves are just like people living with families and trying to survive. The Mexican Gray wolves are a great way to help bring back balance in the local ecosystem. They will also improve the local ecotourism. They will help with the re-vegetation and help the bird population return to its former glory.

It is estimated that monk seals have been living in the Hawaiian island chain for 14-15 million years. It is believed that they reached the Hawaiian archipelago through the Central American Seaway, which closed approximately 3 million years ago. They are considered by many to be a “living fossil” due to the primitive nature of the species. Both remaining species of monk seal are in imminent danger of going extinct. While the Hawaiian monk seal population numbers approximately 1,100 individuals, the Mediterranean monk seal (Monachus monachus) is fairing even more poorly, with the most recent estimate of 350-450 individuals (IUCN Red List). The Caribbean monk seal (Neomonachus tropicalis) was

The Eastern Gray Squirrel or Sciurus carolinensis is an invasive species for the Western United States. Native of Eastern North America, it was brought to the west through people releasing them in a variety of places such as parks (Hoefler 1990). Even though it was brought away from it’s natural

The Amargosa vole, Microtus californicus scirpensis, is a critically endangered rodent, endemic to the Amargosa Basin near Death Valley, California. This water-dependent species persists in a naturally fragmented wetland ecosystem, that has existed since the end of the Pleistocene (Neuwald 2010). However, due to California’s historic four-year drought and anthropogenic changes, the patchy ecological makeup has been aggravated to extreme limits. The habitat loss and exasperated fragmentation has drastically altered the wetland community and constricted the riparian habitat to less than 20km2 (Foley 2013). This regime shift has forced the Amargosa vole to live in small, isolated populations and has left the species vulnerable to disease (Ott-Conn et al. 2014; Hess 1996; Morshed et al. 2005), and the effects of genetic drift and inbreeding (Neuwald 2010). Consequently, the altered hydrology has increased the potential of the voles’ extirpation with the one-year extinction risk as high as 10% (*).

The issue that will be looked at in this report is the culling of dingos on Fraser Island. Fraser Island lies off the coast of Queensland, Australia, approx. 300km north of Brisbane. It is a large sand island with an area of 1840km2. Fraser Island was added the World Heritage list in 1992 due to its cultural values.

An introduced species is a species that has arrived a new habitat, outside of its native distributional range, by human activity. However, an introduced species can sometimes pose very serious problems to the local ecosystem and require a lot of work and money to manage the issue. This report focus on two main introduced species, the feral water buffaloes (Bubalus bubalis) and the European red foxes (vulpes vulpes) which are both introduced into Australia in the 19th century. The consequences of the introduction of these species and the way of management and recovery of the ecosystem are the main topic of this report. The main methodology for this article is desktop research with the help of information presented by instructors and guides in

The long term goal is to remove it from the federal list of endangered and threatened wildlife and plants. The reclassification criteria will be met when a minimum of 27 metapopulations are established within at least 13 recovery units across the butterflies’ range. The minimum requirement of 27 metapopulations can be comprised of 19 viable normal, and 8 viable large metapopulations. The large metapopulations support 6,000 individuals and the normal size metapopulations support 3,000 individuals. Total delisting of the species would be considered once a minimum of 29 metapopulations (13 viable and 16 large viable metapopulations) have been established within at least 13 recovery units and are being managed consistent with the recovery plan. Actions needed to fulfil this recovery plan are listed as

A company’s strategy is needed first, according to Galbraith’s star model. In starting up her company, Fox Relocation, Gretchen Fox agrees it basically fell in her lap. Working in different firms gave her the opportunity to observe and know what was needed and what worked well in management. As she was thinking up ways to start her own company, opportunity knocked and she took the stride and went for it. Fox knew when she had to expand her company based on clients and employees. I’d consider this the opportunistic strategy since Fox is a go-getter and has her goals and expectations set.
