A Line Transect is a common method used in wildlife and conservation work to count animals and plants in a specific area. Think of it like drawing a straight line through a habitat and counting everything you find along that line. It's similar to doing inventory in a store, but instead of counting items on shelves, wildlife professionals count animals, plants, or signs of wildlife (like tracks or nests) along these predetermined lines. This method helps determine how many animals are in an area and monitor changes in wildlife populations over time. Other names for this approach include "distance sampling" or "transect survey."
