Abstract
  • Landforms are natural features on the Earth’s surface that both reflect and shape geophysical and ecological process. The result is a defining part of landscapes that so often impact on human perception and interactions with environment. Blascyznki (1997) defines landforms as, “specific geomorphic features on the surface of the Earth, ranging from large-scale features such as plains and mountain ranges to minor features such as individual hills and valleys,” and suggests that the analysis and quantification of the Earth’s surface contributes to a better understanding of the physical, chemical and biological progressions that appear within the landscape. Landforms are one of the most important and intrinsic elements of landscape analysis and exploration (Booth, 1983). Landforms provide a physical context for describing the landscape, topography, and ecological units within the environment (MacMillan et al., 2000). Understanding the physical and historical context of the landscape is necessary in order to understand the temporal and spatial scales of ecosystems. Landforms are ecologically important elements because ecosystems develop within landform regions, and material and energy flows occur within the landform system (Swanson et al., 1988).
