Abstract
Abstract The impact of human disturbance on natural ecosystems and wildlife is a worldwide phenomenon and increasing rapidly. Human disturbance is widely regarded as a cause of concern for many taxa, including birds. Disturbance can cause mortality, reduce productivity and affect the movement of individuals. This study investigated some kinds of disturbance that affect waterbirds at the two Libyan Ramsar sites (Ain Azzargha and Ain Ashaghigha) in the eastern part of Libya. The number of waterbirds was significantly negatively affected by the increase of sand collecting sites (habitat change) and heavy traffic of Trucks. Conversely, fishing and recreational activities have no significant effects on waterbirds in Ain Azziana wetland. Habitat change and destruction are the key factors that cause losing of natural ecosystems components.
