Landscapes, Scale, and Government Policy :: Argumentative Persuasive Essays

Landscapes, Scale, and Government PolicyThe process of grace kind have finally caught the attention of the public and governments of the United States. Now that we atomic number 18 equipped with the knowledge that we must at least control our cause on decorates, we should ensure that our policies are a reflection of informed and completed decisions. This has been proven to be very difficult, as there are umteen a(prenominal) factors that must be considered when addressing landscape change including issues of spatial and temporal scale of measurements of landscape processes. This type of scale is best described as the spatial or temporal dimension of a certain process (Turner, 2000). Scales may vary, ranging from the bulky temporal and spatial scale of plate tectonics to the fine scale processes of insect herbivory. Landscape change has contrastive effects along unalike levels of scale, and thus, should be treated similarly as well. These varying scales must be consi dered when drafting the many policies that contend with the changing landscapes in order to direct out a positive effect.Landscapes are controlled by dynamic variables crossways different scales that occur within the environment. Wildfires, herbivory, climate, and development, among others, all contribute to those transformations. These types of landscape disturbances tin also occur across different scales, both spatial and temporal. fence a diminished brush fire occurring in the backyard of a small residential neighborhood for a few hours before becoming eliminate by the local fire department. The spatial and temporal scales of this type of landscape disturbance are minimal. When compared to the Cerro Grande wildfires that occurred in New Mexico during May of 2000, the effects of the said(prenominal) type of disturbance are vastly different. As a result, the Cerro Grande say Fire had burned over 45,000 acres for almost 2 weeks and forget have left the landscape in a dramatically different state (NPS, 2000). We can see the vastly different effects of severally of the same disturbance on the landscape.These scaling effects may be applied to other types of landscape change as well. In many studies, landscape ecologists such as Monica Turner, Dean Urban, and J.A. Wiens are including issues of scale as an integral part of their research. It is now evident that every change in scale brings with it changes in patterns and processes (Wiens, 1989.) All landscapes are dynamic including anthropogenic landscapes.
