The distribution and global habitat association of the North African houbara bustard ( Chlamydotis undulata sensu stricto ) were studied for the first time in a large semi‐arid steppe‐land region in eastern Morocco. The study area has been protected from hunting for 6 years, but was still under significant pressure from grazing activities. Houbara distribution was assessed using point count surveys conducted during the 2002 breeding season and compared to natural‐ and human‐related predictors. The hierarchy and quantification of influences was evaluated using a discriminant function analysis. Micro‐topography first drove houbara bustard distribution, since birds were usually found in open flat tracts allowing visibility over a long distance for the prevention of potential predator approaches, but also for breeding males to be seen by conspecifics. ‘Flooding surfaces’ presenting concealment possibilities, as well as readily available food resources, were secondly sought. Proximity to wells was a surrogate to human presence and pastoral activity influences and appeared to affect houbara bustard distribution. The weight of human disturbance on houbara distribution is highlighted and it is recommended that this should be considered in conservation plans.
