23. Buffer Analysis Riparian buffer analysis to build upon GIS model Riparian buffer analysis to build upon GIS model Review vegetated cover within 100-foot stream buffer for each stream segment Review vegetated cover within 100-foot stream buffer for each stream segment 5 tiered system: 5 tiered system: 1. Pristine – complete cover 2. Impacted – majority cover with some human activity 3. Managed – human activity actively degrades streams; buffer absent on one side 4. Degraded – buffer mostly absent on both sides 5. Absent – no vegetated buffer 8/26/2015 Past Projects New Techniques
