The following points highlight the five methods of sampling plant communities. The methods are: 1. Transect Method 2. Bisect 3. Trisect 4. Ring Counts 5. Quadrat Method. 1. Transect Method: When the vegetation is to be studied along an environmental gradient or eco-tone (e.g. tropical to temperate, high or low rainfall areas or precipitation gradient, adjacent areas with different types [...]
