In t h e s e circumstances the original use may be redundant and owners are tem pted to draw down levels to below the 25 000 cubic m etres volume at which the acts come into operation. Unfortunately, this has the effect of reducing small lochs to m ere puddles with potentially disastious ellects on the wildlife associated with them. In one iecent ruse the nesting habitat of four species of birds included on schedule 1 of the Bird Protection Aits was threatened. The reasons to r and safetyaspects of these a d s was made quite cleai in "Governm ents ignore time bombs in lb item's dams" (This Week, 29 Ja nua ry, te p 2bilj mil t h e lecenl HUG televisual progiam m e.
