Grassland transect sampling for 20 Aster prenanthoides

Researcher's went to York University's Grassland's and observed Aster prenanthoides. For this dataset, the researcher's used a 20 m transect and randomly placed it linearly on the ground. Then they selected Aster prenanthoides as their target species because there were many of them in that area. The researcher's walked along the transect tape and observed each Aster prenanthoides that they passed in the 20 m range. It was also made sure to only observe the one's that were within 20 cm left and right of the transect tape. Whenever a Aster prenanthoides was spotted, it was given a number and things like its distance on the transect(in m), its height(m), number of leaves that can be observed(split plant into 4 sections, count leaves in 1 section and make assumption for the whole plant), number of flowers and level of crowding (levels 0-3, 0 being no surrounding plant around target species, 3 being over crowded within 50 cm) were observed.
