Volunteers pick up litter and remove
nonnative plants.
It is remarkable that
nonnative fishes have consistently represented a relatively small component of the LCR's fish community over the past 36 y of studies (Kaeding and Zimmerman, 1983; Van Haverbeke et al., 2013).
Among other ecological benefits, native shrubs and trees provide birds and butterflies with vital food and reproductive sites that
nonnative species cannot offer.
Nonnative grasses are a problem because their flammability is higher than that of native grasses, and much higher than that of chaparral shrubs (which are fairly resistant to ignition but burn very hot once lit).
Status of
nonnative English speakers as ESL teachers in the United States (Unpublished doctoral thesis).
Now, the recovery program faces the greatest challenge yet to endangered fish recovery in the Upper Colorado River: successfully controlling
nonnative predators.
It is believed that some
nonnative animals can also cause widespread change to native species, such as the replacement of the red squirrel by the grey squirrel over most of Britain.
The burn will remove
nonnative Manitoba maple and other non-native shrubs in order to allow a healthy native tallgrass prairie to develop.
After a while, the value distinction between native and

The Midwestern native garden; native alternatives to
nonnative flowers and plants; an illustrated guide.
Three researchers from the education faculty in a Canadian Prairie university who frequently conduct research with
nonnative English-speaking participants were interviewed during October and November 2008.
English has become the world's international language, used for international communication mostly among non-native speakers of other languages and 80 percent of all the English teachers around the world are
nonnative English-speaking (NNES) teachers (Canagarajah, 1999).
Nonnative species of fish preying upon native species has been documented widely in North America, particularly in the desert Southwest (Meffe, 1985; Ruppert et al., 1993; Marsh and Douglas, 1997; Brandenburg and Gido, 1999; Knapp and Matthews, 2000; Robertson and Winemiller, 2001; Pilger et al., 2008).
