Forest floor interception
open-in-new
<p>Forest floor interception is the part of the (net) <a href="/facts/Precipitation/uq3nGQc8">precipitation</a> or <a href="/facts/Throughfall/crwggD9h">throughfall</a> that is temporarily stored in the top layer of the <a href="/facts/Forest_floor/ECKTb8Ig">forest floor</a> and successively evaporated within a few hours or days during and after the <a href="/facts/Rain/MLqcQEyx">rainfall</a> event. The forest floor can consist of bare soil, short vegetation (like grasses, mosses, creeping vegetation, etc.) or litter (i.e. leaves, twigs, or small branches). This throughfall is especially rich in nutrients which makes its redistribution into the soil is an important factor for the ecology and water demand of surrounding vegetation. As a hydrological process it is crucial for water resource management and climate change. </p>
