~ The major effect of removing riparian vegetation and wood from streams has been the changes in channel form (widening, deepening and straightening) that have occurred. It is important to consider that we are returning vegetation to a channel system that now has a much larger flow capacity. ~ The major hydrological effect of returning vegetation to streams is via its influence on roughness and...

Grasslands are threatened globally due to the expansion of woody plants. The few remaining headwater streams within tallgrass prairies are becoming more like typical forested streams due to rapid conversion of riparian zones from grassy to wooded. Forestation can alter stream hydrology and biogeochemistry. We estimated the rate of riparian woody plant expansion within a 30 m buffer zone surroun...

In 1995, Stanley Trimble and Alexandra Mendel published a review article focusing in the role cattle play in influencing geomorphic processes, the cow as a geomorphic agent – a critical review. Trimble and Mendel looked at the voluminous, largely unconnected, body of literature on the various means by which cattle affect landscapes. One of the major goals of Trimble and Mendel’s work was to put...

Riparian vegetation, which performs many key ecological functions, has been modified or lost at an alarming rate during the past century as a result of human activity. The aims of this study are (a) to investigate the effects of poplar plantations on plant diversity in riparian zones; and (b) to estimate the ecological implications of extending cover by poplar plantations. For this purpose, we ...
