The presence of original plants
species are necessary and associated with preservation of the ecosystem. However, native plants species can be threatened or even vanish by the appearance of invasive plants species that can alter the ecosystem. Furthermore, invasive plants species are arrive from the external ecosystem which can harm ecosystems, the environment, economic deprivation, and adversely affect of biodiversity and human sanity (Regulation of The Ministry of Environment and Forestry, 2016). For instance, the emergence species
of Acacia nilotica
in Baluran National Park, East Java as an invasive plants. In
fact, Qirom et
stated that almost 9.850 ha from 10.000 ha of this conservation area has been invaded by this plants.
Consequently, they are pressure for pristine plants and animals that live on there.
the Impact of invasive species are not
only in ecological, but also sosioeconomic and human health (Reaser et al., 2007). Primarily, Kaufman
& Kaufman (2012) declared that invasive plant
species can controlled by three ways: biological, chemical and mechanical
First, biological control is involves genuine natural competitor. In
addition, the benefit of this techniques are inexpensive,minor hazard and no peril to human fitness and the environment. In contrast, the negative side of this
ways are extremely spesific on biological agent for each target type and can
not omit all invasive plant species (Kaufman & Kaufman, 2012).
For example, Malacorhinus
irregularis (Coleoptera), an insect is appropiate for biological control against
Mimosa pigra (Heard et al., 2005). Nevertheless, the practice of purely biological control does not generate the expected results and takes long period. However, the merging of several methods such as biological, chemical and mechanical proved to
be successfully applied to Mimosa pigra, in Australia
(Paynter and Flanagan, 2004).
Secondly, chemical control is utilize chemical
material particularly herbiside that are
either destroy target plants or permeated into the plants. Then, the advantage of
this means are murder mentioned plants
and deficient of work force. Nevertheless,
the disadvantages are expensive, unsafe widely impact on the environment
and must be carefully and properly in applying it (Kaufman & Kaufman, 2012). Like in
Beltsville, USA, herbicide glyphosate is fit used to hold the reins of Circium
arvense as invasive plant (Ziska et al., 2004). On the other hand, taking mixture of management, both chemical and non chemical
will decrease the danger of herbicide (Kaufman & Kaufman,
mechanical control is applied with choping or excavating
using some tools or machines and burning. Next,
the profits of this method are cheap
diminishing seed yield. On the contrary, the risks
of this way are need many manpower, land disruption, some invasive plant s are
kind adjusted to flame (Kaufman & Kaufman, 2012). Additionally, to restrain Acacia nilotica in Baluran National
Park, East Java by using a tyrfor tool is more proper than
manual removal. However, this way has an impact on ground level shift of 1% / m2
/ tree (Basari, 2012). On the other hand, Mooney et al (2005) claimed
that blending of mechanical and chemical methods are the top practice.
In conclusion, the most effective method of managing the invasive species is through the application of entire three ways in the integrated system. Thus, the advantages and disadvantages of each approach can be complementary to obtain the optimal result.
