Species Conservation Issues in the Southeast of England

The increasing rate of environmental change is currently a global issue. This could be observed in measurements, such as a temperature fluctuation, rise of water level or could be observed physically such as population fluctuation. Most species vulnerable to such environmental change try to adapt to such changes. The rest die trying to or fly away avoiding them. The theory of Darwinian evolution is simply denoted stating survival of the fittest; making the weak eliminated. While conservationists struggle to conserve the genes that cannot cope with the rapid environmental changes, unexpected domination of species causes a lot of damages to nature. One such drastic outcome is the spreading and co- domination of invasive species. Invasive Alien species (IAS) also categorised under non native species is one massive conservation issues that Southeast England is currently facing. Invasive species could not be defined simply, since the outcome of such species differentiates individually. IAS could be called as a species subspecies or lower taxon that is not naturally occurring at a given locality at a given time, yet introduced to that area, where they could compete or cause damage to species existing in the area, in short or long term. Several of these factors independently or collectively present in a species could make a species an IAS. Similarly, there is a group called Non-native species (NNS), those of which introduced by humans outside of their natural or native range. However Invasive Non-native Species (INNS ) are those which cause unwanted environmental or social impacts by spreading fast and becoming incredibly abundant in the environment (UNEP, 2005,). It is not well understood why some species become invasive and others d... ... middle of paper ... ...re in the United Kingdom.
