English abstract
The environmental impacts of Al-Shatti Road on the coastal habitat at Qurm Nature Reserve (QNR) were investigated over a seven month period from October 2001 to April 2002. The impacts were studied in terms of geomorphology, water quality vegetation and beach user perceptions. Beach profiles along the length of the road and under the bridge from the west side were assessed monthly. Sand samples were collected along the profiles. Profiles showed increasing variability towards the creeks. Sand samples were analyzed by sieving and the results indicated that the beach at QNR is uniform in sand particle size. The particle size of sands showed no differences along the different beach profiles and the mean particle size was mostly in the range 150 to 300um. Analysis of water samples from the two mangrove creeks and from the sea shore indicated no differences in the water chemistry between different sites but there was a monthly difference in the parameters studied. The vegetation cover was studied by conducting four plant transects and comparing satellite images and aerial photographs of the ONR before and after road construction. Five plant species were found on the dunes and the mangrove Avicennia marina, along the creeks. There was a loss of trees and shrubs and a total loss of about 7 ha of vegetated dune area to the road. The social survey of beach users revealed an increase in the number of beach users after the construction of the road and many interviewees wanted more roadside facilities. The main activities of beach users were exercise and resting. Interviewees were mostly in favor of the road and felt it had improved the area. It is concluded that the new road has caused loss of some dune habitat but little other damages to the area and is perceived by beach users as a positive development. The data provided here can form the basis for future monitoring of this important recreation/conservation area.
