Which sampling method involves counting the number of individuals observed as you move along a line?

Explanation:
Line-transect surveys involve moving along a line and counting the individuals you observe from that line. As you walk, you may note each sighted individual and often measure its distance from the line, which helps estimate density while accounting for detectability. This approach directly captures counting while traversing a line, which is exactly what the question describes. Quadrant sampling uses fixed plots (quadrants) placed across the area and counts all individuals inside each plot, not counts gathered as you move along a line. Point sampling (basal/prism) collects data at specific points rather than along a transect, counting trees around those fixed points. Ecologic land classification maps land cover types rather than counting individual trees along a line.
