Glades | MDC Discover Nature

Glade communities are distinguished by their underlying rock type, which strongly influences the soil chemistry. Igneous, chert, and sandstone glades, for example, tend to have acidic soils, while dolomite and limestone glades are calcified, with alkaline or neutral soils. Soil type is a big influence on which kinds of plants grow there.
