Method synopsis

Systematic point sampling along transects to quantify vegetation composition and forage quality metrics. Modified from standard methods described in Wilkening et al. 2011.

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 — Determinants of pika population density vs. occupancy in the Southern Rocky Mountains (2014), Ecological Applications. Implementations in other papers (listed below) may differ.

1. Vegetation sampling
   Vegetation was sampled along three parallel transects at each of three randomly selected logger locations per site. Each transect was 50 m long: central transect centered on logger running perpendicular to dominant aspect, with transects 15 m upslope and downslope. Vegetation was quantified at 1-m intervals using line-point-intercept method resulting in 150 points per logger location and 450 points per site.
   Quantities: 3 logger locations per site, 3 transects of 50 m each per location, 150 sample points per location, 450 points total per siteDuration: Sampling conducted during field seasons, specific timing not providedConditions: Transects oriented perpendicular to dominant site aspect
