Invasive Grasses of North America

Invasive Grasses Of North America

Grasses are one of the most abundant floras on all continents except Antarctica. Their divergence is estimated to have taken place 200 million years ago. Humans have intentionally and unintentionally introduced these species to North America through travel and trade. On the North American plains, prairies, grasslands, and meadows at least 11% of grasses are non-native. North America is considered a hotspot for many invasive plant species of grasses, which threatens all of the endangered native grass species and potentially threatens other grass species. Conservation tactics and management policies can help prevent invasive species from taking over and driving native North American plants to extinction.

Famous quotes containing the words north america, invasive, grasses, north and/or america:

    The North American system only wants to consider the positive aspects of reality. Men and women are subjected from childhood to an inexorable process of adaptation; certain principles, contained in brief formulas are endlessly repeated by the press, the radio, the churches, and the schools, and by those kindly, sinister beings, the North American mothers and wives. A person imprisoned by these schemes is like a plant in a flowerpot too small for it: he cannot grow or mature.
    Octavio Paz (b. 1914)

    The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.
    Jean Marzollo (20th century)

    ‘I’m sorry that I spelt the word:
    I hate to go above you,
    Because’Mthe brown eyes lower fell—
    ‘Because, you see, I love you!’

    Still memory to a grey-haired man
    That sweet child-face is showing.
    Dear girl! the grasses on her grave
    Have forty years been growing.
    John Greenleaf Whittier (1807–1892)

    So-called Western Civilization, as practised in half of Europe, some of Asia and a few parts of North America, is better than anything else available. Western civilization not only provides a bit of life, a pinch of liberty and the occasional pursuance of happiness, it’s also the only thing that’s ever tried to. Our civilization is the first in history to show even the slightest concern for average, undistinguished, none-too-commendable people like us.
    —P.J. (Patrick Jake)

    Yesterday, December 7, 1941Ma date that will live in infamy—the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan.
    Franklin D. Roosevelt (1882–1945)
