A scientific report on a peat bog states: "The waterlogged, highly acidic, and nutrient-poor soils restrict decomposition rates. Sphagnum\textit{Sphagnum}Sphagnum mosses carpet the ground, maintaining acidic conditions that limit other flora, while carnivorous sundew plants (Drosera\textit{Drosera}Drosera) capture insects to supplement their nitrogen intake. The fluctuation of the water table and soil pH directly determines the distribution and survival of these specialized organisms."
