Document Summary
What factors in uence the distribution of different forest types across the landscape: climate, elevation, geographic position, physiography, landform, parent material, local elevation, topography (slope, aspect, local climate. ^ this list moving down from largest/coarsest scale, to a ner scale. Hydrology: therefore , similar ecosystems develop on similar landforms. Friday, september 23, 2016: repetitive patterns across the landscape. Speci c landform: type, size, affects topography (coming up) Elevation (local) affects: climate (temperature, growing season, occurrence of frost, precipitation) and thus, soil development. Need to consider in the context of latitude (is 3000m elevation the same in peru as in the yukon?) Slope steepness: steeper - more rapid drainage, movement of snow, soil, erosion. When there is no slope, what determines where the water will move is the texture of the soil. Another important thing to think about: where you are in terms of elevation. Think about elevation and topography at different scales and in terms of relative differences.
