Vegetation structure (1 study): One study in Indonesia found that a peat swamp forest corridor contained 5,819 trees/ha. This included 331 large trees/ha, 1,360 saplings/ha and 4,128 seedlings/ha. Overall plant richness/diversity (1 study): The same study recorded 18–29 tree species in the peat swamp forest corridor (the number of species depending on the size class).

This study was in bogs. Vegetation cover (1 study): One replicated, paired, controlled study in bogs in the UK found that total vegetation and shrub cover were greater where grazing intensity was lower. Cottongrass cover was greater where grazing intensity was lower (one species) or unaffected by grazing intensity (one species). Vegetation structure (1 study): The same study found that vegetation biomass was higher where grazing intensity was lower.

The study was in a fen. Characteristic plants (1 study): One before-and-after study in a fen in the USA found that following restoration of water inflow across a road (along with general rewetting), cover of wet peatland sedges increased whilst cover of grasses preferring drier conditions decreased.
