Method synopsis

Camera traps deployed along trails in a stratified random design to detect wildlife presence and estimate occupancy while accounting for detection probability. Cameras moved weekly within zones to sample entire trail segments over study period.

Synthesized from method descriptions across 4 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Differential response of three large mammal species to human recreation in the Rocky Mountains of Colorado, USA (2023), Frontiers in Conservation Science. The protocol was originally introduced by The effects of recreational trail use on small mammal species richness and abundance (2020). Implementations in other papers (listed below) may differ.

1. Camera deployment design setup
   Placed cameras along the first 1500 m of each trail to standardize camera spacing among all trails. Each 1500 m trail segment was divided into six zones, each of which contained one camera. Each zone was divided into six subsections, and every week one subsection was selected in each zone for the camera to be deployed for seven days.
   Quantities: 30 cameras total (6 cameras per trail × 5 trails), 1500 m segments, 6 zones per trail, 6 subsections per zone, 7-day deployment periodsDuration: Cameras moved weekly throughout study periodConditions: Stratified random design to ensure every portion of each trail was studied throughout the study period
   Equipment: 30 camera traps
2. Camera trap deployment
   Used digital camera traps (Browning Strike Force Model BTC-5HDPX, Prometheus Group, LLC, Birmingham, Alabama, USA) to record human and wildlife activity on trails. Cameras were placed next to the trail and pointed at the trail so as to capture movement along the trail and focused on images of animals moving along the trails. Motion-activated cameras captured a single still image when triggered by movement from a human, animal, or vehicle, with a delay of one second between photos.
   Quantities: One second delay between photosDuration: Five-week period in June-August 2020, each camera deployed for seven days before being movedConditions: COVID-enhanced 2020 summer tourism season, peak tourism season
