transect

a line across a habitat or habitats along which organisms are sampled in order to study changes that may occur along that line. Transects are most frequently used in studying changes in vegetation (often a particular species) across a physically changing habitat such as blanket bog or sand dunes. A belt transect may be considered as a widening of a line transect or as a continuous line of QUADRATS, and all plants within the belt are recorded, as opposed to only those t ouching the line in the case of the line transect. Recording in a belt transect is much more time-consuming but gives more accurate results. Association transects are very long and usually only dominant species or ASSOCIATIONS are recorded.
