Introduction
Due to the ever growing population urban areas are predicted to grow by a significant amount in the near future due to the increasing human population. The housing built to deal with the expanding human population is likely to high-density, low- cost housing with small gardens. An experiment was done to see the effect this will have. In an experiment they used a questionnaire to analyse the factors affecting the use of gardens by a number of different mammals. They recorded 22 species/ species groups. The pattern of use of the garden by individual’s species was limited only six species/species groups were frequent visitors under 20% of the gardens. All of the species recorded seemed to be negatively affected by the decreasing …show more content…
The red squirrels are out competed by grey squirrels in deciduous and mixed woodland as the grey squirrels utilise available food resource more effectively and they are able to eat poisonous food for red squirrels by detoxifying it for example acorns(Warren 2002).
Another reason for the decline of the red squirrel population in the UK has been caused by direct and disease-mediated completion with the grey squirrel. The grey squirrel is a recevoir host of the squirrel pox virus (SQPV)(Bruemmer et al. 2010)The squirrel poxvirus causes a high mortality rate in red squirrels. The SQPV produces skin lesions: ulceration and erythematous exudative dermatitis (Fowler and Miller2008)
The European Otter (Lutra lutra). The population of European otters is decreasing in the //UK in 2004 there were roughly a total number of 10,395 otters. It lives a wide number of different aquatic habitats which includes lowland and highland lakes, streams, rivers, swamp forests, marshes and costal area. In most areas the otter lives the occurrence of bank ide vegetation is correlated with the occurrence if otters this shows how important this vegetation is for the otters and in order to breed they need cavities among tree roots, holes in the river bank or piles of wood, debris or
