Biology Assignment

This document is a response to a discussion on the grassland biome in Florida and the impact of invasive species. It discusses the characteristics of the grassland biome, including climate and vegetation, as well as the threats posed by invasive species. The document also mentions conservation policies to prevent and manage the damage caused by invasive species.

Response to discussion:
I am based at the temperate deciduous and flooded grassland biome of Florida.
Typically, North America can majorly be studied under 8 biome categories that include,
tundra, taiga, temperate deciduous forest, scrub forest, grassland, desert, tropical rain forest
and temperate rain forest. It should further be noted in this regard that the creation of a biome
is largely dependent upon the climatic factors such as temperature, humidity and
precipitation. The grasslands are also referred to as ‘Prairie’ or ‘plains’. The average
precipitation rate within the biome where I am based is equivalent to 20 inches or 51 cm,
annually (Dietze et al., 2014). Also, the precipitation is higher during the sowing season
which accounts for the favourable growth of perennial grasses as well as herbs. However, the
river valleys do not favour the growth of forests. The biome also comprises of ‘bad-lands’
that are unfit for cultivation, for example, the region of Southern Dakota. Forest fires caused
due to lightening forms the most common environmental disaster that affects the stability of
the biome. The geological past reveals that the biome had been subjected to manmade fire
disasters as well that had resulted in the widespread destruction of shrubs and trees. However,
the main vegetation of the area includes perennial grasses that have possess underground root
and shoot system which are not destroyed by the environmental disaster. On account of the
invasive grassland, the biome shelters abundant of herbivorous organisms that include Bison
and Antelope (Donovan et al., 2017). Also, a large population of swift, herbivorous ungulates
are found in this region pertaining to the lack of appropriate shelter for predators. The
grasslands are also serve as optimal reserves of corn, wheat and grains that is used for
domesticating farm animals such as sheep and cattle. It is important to note that this area is
capable of high productivity if cultivated. Optimum rainfall can be attributed to the reason
that does not leach the soil minerals and make it unavailable for the roots of the plants to

uptake the minerals. The local income of this region comes mainly through cattle rearing
activities.
Invasive species can be defined as the non-native species that are introduced within a
specific geographical location. These invasive plant or animal species are alien to the native
ecosystem and pose a great threat to the harmonious equilibrium of the ecosystem (Zhang et
al., 2013). Invasive species have been studied to disrupt the ecological equilibrium by
negatively impacting the environment of the natural biome. Feral pigs causes a major threat
to the grassland biome as it devours a large proportion of the grass (The Nature Conservancy,
2019). Studies have indicated that the optimum climatic condition of Florida makes it the
most susceptible to damage by the invasive species (The Nature Conservancy, 2019). Also
the estimated cost of managing damage caused by the invasive species has been compared to
be equivalent to $100 million. In order to prevent the problem, diverse conservation policies
are at place that includes, early detection and response to a detection when it occurs, prevent
future invasions and initiate protection by minimising the damage caused by the non-native
species.
