Datasets for my master's thesis "Plant community convergence on a green tramline – the effects of environmental variables on tramline vegetation"

Datasets for my master's thesis "Plant community convergence on a green tramline – the effects of environmental variables on tramline vegetation" for University of Helsinki. Supplemented with my thesis abstract and explanations for abbreviations used in the files. "plants_abundances" shows the abundance data for each species surveyed in summer 2025. "plants_list2024" and "plants_list2025" show the occurence data of the species in 2024 when the tramline was opened and in 2025 when I surveyed the sites.
