When substantively replying to your classmates' initial posts, explain whether you agree or disagree with their assessment and why, ask a follow-up question, mention new information which they or other classmates have not yet mentioned. What are the economic advantages of the park?.What are the ecological advantages of the park.What types of wildlife are found there?.National monument parks do not have sufficient information. Recall that this is a biology class, therefore please select a park that allows you to discuss the wildlife (plants and animals) and ecological and economic advantages as your priority.You will not receive credit for a park that has already been chosen or for a state park. There are a lot of parks, so make sure you choose one that is different than your classmates and use it in the title of your post. Choose the state in which you reside, or if you are deployed, one that you have visited or are interested in visiting.Find a National Park ( not a State Park):.Listing of these websites does not and is not intended to imply endorsement by the National Park Service of commercial services or products associated with the sites. Shenadoah National Park - Invasive Plant Information Though it is not humanly possible to eliminate all invasive nonnative species at this time, the Park is engaged in a number of strategic actions including inventory, control, monitoring, and site restoration.Ī website that provides helpful information about invasive nonnative species is: Executive Order #13112 on Invasive Species instructs all non-defense agencies to control invasive nonnative and not permit new infestations. National Park Service policy on nonnative species directs that they be managed if their presence threatens natural or cultural resources, or human health or safety, and if control if feasible. It escaped to dominate mid-Atlantic forest edges and openings. Tree of heaven was brought into this country in the 1780s for arboretum plantings.The Park has a small infestation it controls along its eastern border. It now covers millions of acres in the South. Kudzu vine was originally brought to America in 1876 to decorate house arbors.Starlings are commonly seen at Big Meadows. They are known to compete with native cavity nesting birds and have documented ill effects upon northern flickers and redheaded woodpeckers. European starlings were introduced into the country in the late 1880s.
The insect has killed thousands of hemlocks in the Park, destroying valuable shaded riparian habitat along streams and springs. Hemlock woolly adelgids were accidentally introduced into this country on imported hemlock nursery stock.Millions of trees died in the Park during the epidemic of 1986-95. It was accidentally released near Boston, Massachusetts. Spongy moths (formerly named gypsy moth) were brought to this country in 1869 for genetic crosses to create a more productive silkworm.If invasive nonnatives are not actively and aggressively managed, the National Park System is at risk of losing a significant portion of its biological resources.Įxamples of invasive nonnatives found at Shenandoah include: Of the 350 nonnative plants in Shenandoah, roughly 35 (10%) are considered problematic invasive species. Hybridization with exotics alters the genetic integrity of native species. Invasive nonnatives disrupt complex native ecological communities, jeopardize endangered native plants and animals, and degrade native habitats. These invasive nonnative species are among the most serious threats that parks face today. While many nonnative species have minimal or even beneficial impact on recipient sites, some are more problematic. Accidental introductions have been through unintended releases and biological hitchhiking on vehicles, personal effects or trade goods.
Purposeful introductions were for game management, wildlife habitat enhancement, industrial development, soil erosion protection, or just to remind settlers of their first homes far away, among other reasons.
Nonnatives were introduced with the earliest European immigrants, but new introductions continue today.
