Paper 1 · vegetation survey methodology
Which sampling method involves marking out a grid of sample plots spread across a study area and recording the vegetation within each plot, rather than recording along a single line?
ATransect sampling, using a single line of measurement drawn across the area
BQuadrat sampling, using a grid of sample plots spread across the study area
CInterview sampling, relying on local residents' memories of past vegetation cover
DAerial sampling, using photographs taken from an aircraft or drone only
Explanation: Quadrat sampling lays out a grid of fixed-size sample plots across the study area and records vegetation within each plot, giving area-based coverage; a transect instead records vegetation at intervals along a single line.
