The thickness of the layer of vegetation can be a contributing factor as thicker layers have a greater capacity for storing water. [1] There is an observable seasonal response throughout the year. In Fall, leaf fall accumulates on the forest floor to increase the thickness that then slowly decomposes. [1]
Mor humus is a form of forest floor humus occurring mostly in coniferous forests. [1] Mor humus consists of evergreen needles and woody debris that litter the forest floor. This litter is slow to decompose , in part due to their chemical composition (low pH, low nutrient content), but also because of the generally cool and wet conditions where ...
Forest with canopy, shrub and herb layers of vegetation. The following layers are generally distinguished: forest floor (root and moss layers), herb, shrub, understory and canopy layers. These vegetation layers are primarily determined by the height of their individual plants, the different elements may however have a range of heights.
It occurs in the canopy (i.e. canopy interception), and in the forest floor or litter layer (i.e. forest floor interception [2]). Because of evaporation , interception of liquid water generally leads to loss of that precipitation for the drainage basin , except for cases such as fog interception, but increase flood protection dramatically ...
Moder is a forest floor type formed under mixed-wood and pure deciduous forests. [1] [2] Moder is a kind of humus whose properties are the transition between mor humus and mull humus types. [3] [4] Moders are similar to mors as they are made up of partially to fully humified organic components accumulated on the mineral soil.
The understory is the underlying layer of vegetation in a forest or wooded area, especially the trees and shrubs growing between the forest canopy and the forest floor. Plants in the understory comprise an assortment of seedlings and saplings of canopy trees together with specialist understory shrubs and herbs.
This method provides a more accurate measurement as it takes into account differences in structure of the gap descending from the canopy to the forest floor. [2] One of the most recent strategies, pioneered by K. and S.I. Yamamoto, "utilized two photographs of the canopy gap, taken at different heights, and a series of geometric calculations to ...
Mounds are generally observed to be warmer and drier than the forest floor or the corresponding pit; Similarly, the pit is generally found to be colder and have a higher soil moisture content than either the forest floor or the mound. One notable instance where there is an exception to the general observation is when a snow layer has fallen.
