This page provides all possible meanings and translations of the word ombrotrophic
Pertaining to ombrotrophy.
Ombrotrophic refers to soil or vegetation which receive all of their water and nutrients from precipitation, rather than from streams or springs. Such environments are hydrologically isolated from the surrounding landscape, and since rain is acidic and very low in nutrients, they are home to organisms tolerant of acidic, low-nutrient environments. The vegetation of ombrotrophic peatlands is often bog, dominated by Sphagnum mosses. Ombrotrophic circumstances may occur even in landscapes composed of limestone or other nutrient-rich substrates – for example, in high-rainfall areas limestone boulders may be capped by acidic ombrotrophic bog vegetation. Epiphytic vegetation is of course ombrotrophic. In contrast to ombrotrophic environments, minerotrophic environments are those where the water supply comes mainly from streams or springs. This water has flowed over or through rocks or other minerals, often acquiring dissolved chemicals which raise the nutrient levels and reduce the acidity. It leads to different vegetation such as fen or poor fen.
