Assessing the Population Status of a Tree Species Using Distance Sampling: Aquilaria crassna (Thymelaeaceae) in Northern Laos
Figure 3
Detection probabilities for trees with DBH < 10 cm at sites 1–4. Histograms represent the number of trees observed at different distances from the transect line. Smooth curves are detection probabilities predicted by the detection functions. (Bars are scaled such that their total area is equal to the area under the detection probability function (red). Bars may therefore exceed 1, as seen for site 1).
