BIODIVERSITY1Executive SummaryThe report is based on the assessment of the butterfly biodiversity in Monks Wood over thecourse of 40 years. The analysis involves calculation of the total number of individuals,species, species diversity and species evenness. The other objective includes whether thetime related patterns are detectable within the concerned data. The data accumulated isanalyzed using a statistical package called PAleontological STatistics (PAST). Thefindings suggest that North Atlantic Oscillation (NAO), both the positive and negativeindex played a key role in butterfly biodiversity.

BIODIVERSITY3IntroductionBiodiversity is defined as diversity of the living organisms in marine, terrestrial andaquatic ecosystems and the ecological complexities of living organisms are part of; thisinvolves the diversity within the species, among the species in an ecosystem. Biodiversityor biological diversity is an extended term which can be further divided into three differenttypes. The types are species diversity, genetic diversity and ecological diversity (Mace,Norris and Fitter 2012). Species diversity can be explained as the different types of speciesthat occupy a region. In order to measure the species diversity, species richness whichquantifies the different species, and species evenness is the total number of individualswithin the species population. Genetic diversity is the diversity in the genetic compositionof the species in a population. A diversity exists among the species but a larger extent ofdiversity exists within the individuals of a certain species. Ecological diversity is adiversity that exists in a location or an ecosystem. The importance of biodiversity lies inthe fact that it enhances the ecosystem productivity. In biodiversity, biological organismsno matter how small it is, contribute to the environment. For example, a greater variety ofcrop species means a larger variety of crops, ecosystems that are healthy are competentenough to cope with the natural disasters. Like the humans that dominate this planet alsoneeds the to maintain the wildlife to sustain the ecological balance. The factors that affectthe biodiversity include overexploitation, habitat loss, invasive species, climate change(Cardinale et al. 2012). Overexploitation is the over usage of species without providing thetime period to replenish themselves. Habitat loss is considered as the loss of habitat of theanimals due to continuous deforestation. Invasive species are the plants and the animalsthat increase in number due to unhindered competition from the other species. Climatechange is the global or local changes in the climatic phenomenon that hampers and hindersthe natural ecosystem. There are several evidence where the human activities have resultedin biodiversity loss, such as the overexploitation of the and over usage of the fossil fuelwhich has resulted in the rise of pollution. Due to the rise in pollution the globaltemperature has increased which again has increased the incidences of major diseases,global rise in sea level and the rise in storms and landslides (Intergovernmental Panel onClimate Change 2014). The merit of producing the wild life sanctuaries within the largeurban developments include the benefit of providing a reclamation of the habitat of several
