Human Impact

 Many of the native vernal pool species are impacted by urbanization. The environment that they need is being replaced by human developments and the urban landscapes are introducing lethal dangers to the wildlife of vernal pools. For example, amphibians and other creatures encounter roads and buildings during their migration for forestry. The encounters present a high mortality rate of the species because of the hazardous cars on the roads. Also, there are amphibians that tend to stay away from the human productions and are therefore presenting the issue of genetic isolation and are increasing the chances of inbreeding. The need to expand land as human population grows is inevitable and the vernal pools are being removed or being intruded by the development of housing and industries.

This vernal pool mostly consist of shallow cattail march without any other plant variation.It was disturbed by an urbanization project that did not consider the pool and the harms that there productions caused.This photo displays the direct impact of urbanization. Timber harvesting also plays a part of the elimination of vernal pools because the lack of trees results in change in the amount of sunlight, leaf fall and alternation of the depression in the ground.
