    The effect of forest fragmentation is a growing concern among ecologists and forestry managers. Habitat fragmentation is often defined as a process during which “a large expanse of habitat is transformed into a number of smaller patches of smaller total area, isolated from each other by a matrix of habitats unlike the original” (Wilcove et al., 1986). The exact definition of fragmentation differs among studies and commentators, but such features as size of biggest fragment, total amount of perimeter

    Prior to conservation efforts, the Florida panther has suffered several population losses due to inbreeding, habitat loss, and vehicular collisions with only an estimated 30 surviving individuals in the 1970s (Maehr 1992). The number one threat to the Florida panther is habitat loss and habitat fragmentation due to urban development in Southern FL within the hardwood hammocks and wetland habitats in which they live in. Most of the current panther population is located within public lands such as the

    our neighbourhoods their home. The Fraser Valley, “one of the most important and complex ecosystems in the country” (Thom, p. 171), has been dramatically altered to make a more convenient landscape for housing and farming. In this process, critical habitat has been destroyed and many species that were once abundant have disappeared from our area (Cuthbert p. 24). Urbanization is ongoing and is thought to be the most significant threat to the incredible biodiversity found throughout British Columbia

    ‘no net loss’ goal, but instead have a species recovery goal. Both conservation and wetlands mitigation banks are privately or publicly owned lands which are protected and managed for its ecological value. By doing this, the bank sponsor generates habitat or wetland or stream credits to sell to developers or transportation departments who need to offset their impacts and comply with the legal requirements for the permitting of development or roadway projects. Both types of banks offer benefits to both

    Natural habitats used by man or tampered with tend to become unsatisfactory or unsuitable for the native wild species. As I learned in class, habitat loss is the number one threat to modern primates. Not only do primates suffer, but habitat loss is the greatest threat to various parts of life on this planet that humans have caused. Simply speaking, along with habitat destruction, ties in the extinction of diverse species. “Biodiversity as a whole forms a shield protecting each of the species that

The aim of this study was to 1) determine how the proportion of habitat patches occupied influenced the change in patch incidence and 2) investigate how the extinction and migration rates influence the amount of patches occupied. Methods and materials Deterministic equilibrium model A vensim model was set up according

    Goldman, who wrote the article, “Endangered Species Act,” explains the details and the importance of the Endangered Species Act of 1973. The article suggests that human activity is the lead cause of species extinction. Human kind brings loss of habitat, pollution, and overharvesting. What people do not realize is that species biodiversity has many health benefits for them. Whether it is a substance used in pharmaceuticals, or improving the quality of the environment, a species has its effects on

    introduced as a mistake (Evans). Many environmental scientists consider invasive species as the most dangerous cause of endangerment, because they affect the biodiversity of ecosystems and biological communities, thus affecting the natural food webs and habitats of species. Ehrlich actually contributes fifty-four percent of the one hundred and seventy extinct species, of which the causes of extinction have been reliably identified, directly to invasive species (Ehrlich 37). Therefore, the introduction of

    Wildlife Corridors With the continuously accelerating rate in the loss of wildlife habitat, there is a concern which greets the upcoming century. The problem with the presently remaining "untouched" wilderness is that large whole pieces of wild habitat end up manipulated to suit the needs of human populations. Often times mismanagement of land, besides the mere intrusion into a delicate habitat, exerts stress upon it’s state of equilibrium; so much so that certain species within an area become

The loss of biodiversity also hurts the food supply, especially for country with a dependence on seafood. Almost all staple fish species are either fished to capacity or overfished. Combined with the destruction of marine habitat, experts predict that the global fishing industry could crash by 2048 (Worm). The loss of the fish would have a dramatic effect across the spectrum. Within their own habitat, there would

As opposed to the single species interpretation of the Endangered Species Act (ESA), this act aims at protecting many species using a regional approach to habitat preservation. Douglas Wheeler has written a nice synopsis of the NCCP within the context of the history of conservation of habitat. The NCCP is a program that is meant to have voluntary multi-stakeholder cooperation in planning, management and funding. In Southern California the target habitat is Coastal
