A Review of Current Science and Regulations -- The goal of this report is to synthesize the existing scientific literature on the effectiveness of riparian buffers to improve
water quality through their inherent ability to process and remove excess anthropogenic nitrogen from surface and ground waters. Due to this ability, riparian buffers often are employed as an environmental management tool by resource management agencies. Despite significant research effort toward understanding the ecological functions
of riparian buffers, there remains no consensus for what constitutes optimal riparian buffer design or proper buffer width to achieve maximum nitrogen removal effectiveness.
