lewis & clark campus land coverage analysis: lawn and forested area 1936 & 2005 meghan...
TRANSCRIPT
Discussion Pt. 1
• Why these years? Why these variables?
– 1936 (oldest image) vs 2005 (recent) gives a nice historical perspective
• Looking at two aspects of the campus that are aesthetically prized, but dramatically altered
– Environmental impacts of aesthetic features
Discussion Pt. 2: Results
• Forested area: Reduced from 63.5 to 33.06– Nearly halved
• Less habitat= less biodiversity • Less habitat= increased competition• Reduced trees= increased erosion• Lost to construction= increased impermeable surface
– Increased runoff
• Lawn/grassy area: Reduced from 14.55 to 6.84– Over half lost
• Less grass= less permeable area– Increased runoff– Question of fertilizer use and maintenance over time
