| Përmbledhja≠ | Line-Intercept Sampling (LIS) is an ecological field method developed by Richard H. Canfield in 1941 for estimating vegetation cover, plant density, and structural characteristics in rangeland and forest surveys. By laying a linear transect across a study area and recording all plants intersecting the line, LIS provides efficient, unbiased estimates without requiring plots or quadrats. | Systematic sampling is a probability sampling technique in which every k-th element is selected from an ordered list of the population after a random starting point. With population size N and desired sample size n, the sampling interval k = N/n is computed and one unit is chosen at random from the first interval; all subsequent units are selected by adding k repeatedly. The method is operationally simple, yields a spread-out sample, and often achieves lower variance than simple random sampling when the list has no harmful periodicity. |
