Base-poor

Base-poor

Base-poor in ecology refers to water or soil which has relatively low levels of alkaline chemical bases, such as calcium or magnesium ions. Such environments are usually dominated by organic acids, and so are acidic and are occupied by species tolerant of these conditions or requiring them. Base-poor environments are characteristic of areas where the underlying rocks are sandstone or granite, or where the water is derived mainly from rainfall (ombrotrophic).
