“…The amount, and type of vegetation present within riparian zones is a critical determinant of litter inputs to streams (Benfield 1997). In this study, we found that litter input dynamics varied significantly with land use, and more specifically with the types and amount of riparian vegetation present.…”

“…They suggested that this was the result of a dense understorey and attenuated windspeeds. Benfield (1997) noted the high degree of variability in relative contribution of lateral and vertical inputs to the total litter budget. In deciduous forest sites of the eastern United States, lateral inputs generally made up less than or equal to 30% of vertical litter inputs, whereas in a steep-sided stream in Oregon, the coniferous forest contributed twice more litter to the streams by lateral pathways than by vertical inputs.…”

“…Campbell et al (1992) found that litter inputs to pasture sites in two Australian streams were much lower than inputs to neighbouring forested sites (open eucalypt forest), although they did not note the condition of the riparian zone at pasture sites. In a review of litter input data for streams around the world, Benfield (1997) grouped data from 33 sites according to basic vegetation types. Mass of litterfall in "mixed deciduous" forest did not differ significantly from that in "coniferous" forest, but streams in both forest types had significantly greater vertical litter inputs than streams draining the "other" category (vegetation types comprising shrubs, grasses, and sedges).…”

The effects of varying land use on the inputs of litter to streams were investigated in nine small Waikato, New Zealand, hill country streams between June 1995 and October 1997. Mass, timing, and composition of both vertical and lateral litter inputs were measured. Litter inputs to pasture streams were lower than those to streams in native or exotic pine forest. Litter inputs to native forest streams peaked in summer, with leaf material forming the dominant litter-type throughout the year. The pine forest sites showed a winter minimum, with a pulse of reproductive litter (pollen heads) in spring. One pasture site, where riparian vegetation included willow and poplar showed an autumnal peak, with low inputs at other times of the year. Climate variables (air temperature, rainfall, and windrun) varied in their power of prediction of litter inputs. Mean air temperature showed a strong positive relationship with monthly litter input at the most intensively sampled native forest site. Annual litter inputs were positively related to canopy cover, although canopytype modified this relationship. At several sites lateral inputs of litter showed a positive relationship with the slope of the contributing area. Overall, lateral inputs were positively related to % unvegetated groundcover. In open pastures the combination of a lack of riparian trees, and the potential litter-trapping capacity of pasture grasses, severely limits inputs of coarse particulate organic matter to streams.

“…In temperate forested streams, most litter inputs occur in autumn after leaf abscission, i.e., during high discharge and surface runoff following high rainfall in the autumn and winter, even though a substantial part of detritus from the stream banks and the adjacent zones may also be subject to lateral movement and therefore continue entering streams over the whole year (Benfield, 1997). In parallel, as reported by Brunke and Gonser (1997) and Naegeli et al (1995), even though, usually most of the fine and coarse POM are carried in the sediments during floods (i.e., late autumn and winter), Bretschko and Moser (1993) demonstrated that in a porous gravel stream more than 80% of the annual POM input was transported into the sediment in spring and summer during high discharge fluctuations, while a small proportion (i.e., < 10%) entered after litter fall.…”

-Headwater woodland streams are primarily heterotrophic: they receive substantial inputs of organic matter from the riparian vegetation, while autochthonous primary production is generally low. A substantial part of leaf litter entering running waters may be buried in the streambed because of flooding and sediment movement. Although the general significance of the hyporheic zone for stream metabolism has been reported early, organic matter storage within the sediment of streams has received less attention, with most studies only quantifying accumulations at the streambed surface and ignoring other stream compartments. In the present study, the amounts of three fractions of coarse particulate organic matter (CPOM; > 16, 4-16 and 1-4 mm) were determined in late autumn and early spring in the interstitial and benthic zones of three headwater streams of the Montagne Noire (South-Western France) differing in their substratum grain size. Our findings demonstrated that the total CPOM content in the interstitial zone can be much (up to one order of magnitude) higher than at the sediment surface. The sandy bottomed stream exhibited a higher amount of CPOM (whatever the size fraction) than the two other streams, suggesting that the sediment particle size may be a major determinant of CPOM storage. Given the large amount of organic matter stored in the interstitial zone, this compartment may play an important role for the carbon turnover and associated trophic dynamics in the stream ecosystem.

“…Wood enters streams mainly by litterfall from trees but also laterally by being washed into the stream during inundation of floodplains (Benfield 1997). However, the lateral input of wood litter from the floodplain to the stream can be higher sometimes than the amount of litterfall (Cuffney 1988).…”

Vacuum‐pressure prewetting—A simple and rapid method to water saturate wood for experimental purposes

A simple and rapid method to prepare water‐saturated wood by vacuum‐pressure prewetting is presented. Submerged wood pieces can be prepared easily for any experimental purposes without long periods of prewetting and without additional tools for holding the wood under water. The particular wood piece must be submerged in a water filled suction flask that is connected to a diaphragm vacuum pump. Due to the evacuation of the air from the flask the wood rapidly soaks up water until it is saturated. In the experiments, branches displayed a logarithmic water saturation curve soaking up the highest amount of water during the first 10 s of air evacuation. Most branches were water saturated during this time. The method works best for wood pieces with a low or medium density supporting a rapid soaking of water, whereas very dense wood needs much more time to become water saturated. The main problem of the method is the loss of bark material from natural branches and the splitting of larger woods due to the rapid swelling caused by the water uptake. However, this method could be used for any experimental purposes needing standardized submerged wood, like investigations of epixylic biofilm development, colonization of wood by aquatic invertebrates, decomposition of submerged wood, or invertebrate food choice experiments.
