March 2002 FFf]R N O T E The increase in the population of the Wild Ass and the loss of their grazing areas in the Rann has lead to the out-migration of some of these animals from the protected environs of the sanctuary. The reported crossings of the corridor and regular sightings of Wild Asses close to the State Highway 07 was an issue that was studied in detail in 1999, when the environmental assessment for the said corridor was initiated as part of Phase IIB studies. One important finding in the study has been that not a single incidence of collision of a Wild Ass with a vehicle has been reported in the last five years and the data prior to that period is not available. However, since the species is an endangered one and last of its kind that is present in the world, the study had proposed some measures for their safety. It may be noted that all measures proposed, as part of this project, are preventive in nature. Collisions are only a perceived threat, due to increase in number of vehicles plying after the rehabilitation of the Highway. Since then, continuous development has been taking place in and around the project region. A major change has been the initiation of construction of the Narmada Canal - a branch of which runs east to west, almost parallel to the sanctuary boundary (Refer Attached Map). The approximate length of the canal running parallel to Phase IIB corridor is about 28 kms. Once completed, the canal will act as a physical barrier and will prevent the Wild Asses from crossing over into the Surendranagar - Nal Sarovar region from their natural habitat in Little Rann of Kachchh area. In such a situation, the mitigative measures suggested in this report may not be relevant and will require modifications to suit the needs of the situation. However, since the canal construction is still under a slow progress, the management plan has not been totally discarded. The final decision in this regard will be taken up before the tender documents for Phase IIB are finalized and issued.
