Method synopsis

RASTER-based spatial analysis to quantify multiple metrics of anthropogenic disturbance including distance to infrastructure and proportion of impervious surfaces within species-specific buffer zones.

Synthesized from method descriptions across 5 papers using this protocol.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Quantifying human disturbance on antipredator behavior and flush initiation distance in yellow-bellied marmots (2011), Applied Animal Behaviour Science. Implementations in other papers (listed below) may differ.

1. Quantify human disturbance
   Continuously recorded presence of motorized vehicles, bicycles, and pedestrians within 300m of each colony. Calculated disturbance indices correcting for distance from colony edge, with separate indices for total vehicles, bicycles, and pedestrians using bimodal distribution categorization.
   Quantities: 12 days of recording during peak tourist season (late June to mid July), within 300m radius of coloniesDuration: 7:00 to 18:00h daily for 12 days during peak tourist seasonConditions: Peak tourist season timing, every other day sampling
   Equipment: observation equipment for human activity monitoring

Typical Equipment

• RASTER grid systems
• US Census Bureau data
• RMBL GIS data
• RMBL Spatial Data Platform
