Méthodes déchantillonnage

Data is collected by using transects and quadrats. Each site is divided into subfields; in each sub-field, 1-3 (depending on field size) 30-meter (m) transects are placed at either a random (SF, GH, TG) or chosen (BF, PF) location. Each transect rope is laid out in a southern (compass bearing 180°) direction. Along this transect, a 1x1 m quadrat is placed at 5 m, 15m, and 25 m along the western (right) side of the transect rope. Inside the quadrat each species is identified as low as possible in taxonomic rank; the goal is to species but sometimes there is only time to identify to genus or family. The percent cover for each species is then estimated using pre-measured cardboard squares (1-10%) as reference. The total live vegetation percent cover of a quadrat does not have to equal 100% (and often was greater) due to layering of vegetation. Bare ground and dead vegetation percent cover were also estimated within each quadrat. Each transect location is sampled twice, once in the Early Season (typically May-June) and once in the Late Season (typically late July-August).
