Condition of the snail population and its habitat at Waun Eurad was carried out by measuring environmental variables and snail numbers at intervals along two linear transects (64m and 105m in length). The attributes used to assess Condition were: - Area of occupancy of Vertigo geyeri habitat in both transects - Area of occupancy of Vertigo geyeri in both transects - Number of overall positive recordings per number of field samples - Hydrological field assessment Condition at Cors Erddreiniog was assessed by a survey of the compartments of the site where V. geyeri had been previously recorded or supported suitable habitat, plus a more detailed survey of the area where V. geyeri had been recorded most often. The attributes used to assess Condition were as based on area of occupancy of snail habitat, area of occupancy of snail, number of overall positive recordings per number of field samples, and hydrological field assessment.
