| Tóm tắt: | The Earth's flora is dynamic and has been
constantly changing over a period of time.
Changes may be natural or human-aided,
although in the recent past the latter has
played a vital role. In fact, the movement of
plants from one part of the earth to the
other has become very common and fre-
quent owing to better trade and transport
facilities. Plant species that move from one
geographical region to the other (either
accidentally or intentionally), establish and
proliferate there and threaten native
ecosystems, habitats and species are known
as invasive alien plants (hereafter referred
to as invasive plants) (Richardson et al.,
2000).
The problem of invasive plants has become
global and is largely human-aided (Vitousek
et al., 1997). Invasive plants are responsible
for global environmental changes, bio-
diversity crisis, species endangerment and
disruption of ecosystem processes essential
for human welfare (Drake et al., 1989; Parker
et al., 1999; Mack et al., 2000; Mooney, 2005;
Charles and Dukes, 2007; Herron et al., 2007,
Pejchar and Mooney, 2009). The impact of
invasive plants on global biodiversity is
second only to habitat fragmentation and is
a major global issue. |
