Mesotrophic Lochs
Protected Species at Rohallion

There are several types of habitat in the proposed development site, offering wide bio-diversity.
Twenty species of trees, 100 + species of wild plants and the water system support many insects, birds and mammals, including several protected species.

  The construction phase of the development of 49 dwellings will necessarily be long-drawn out and disruptive to wildlife, also a pollution risk;  ongoing habitation by 49 families with children, dogs and cars likewise.

Rohallion and the other lochs are mesotrophic, which means that the nutrient level is right for sustaining a healthy ecosystem and diverse plant communities.  Exposure to excessive nutrients, as from sewage and garden fertilizer run-off, encourages algae, which blocks light to the aquatic life, thus destroying the whole ecosystem.

The importance of protecting mesotrophic lochs is now highlighted as a major concern, and most have SSSI status. Nearby the Loch of the Lowes and associated lochs are mesotrophic SSSIs and candidates for protection under an SAC (Special Area of Conservation) scheme.  It is the quality of such lochs that attracts the Ospreys.
