Isle of Skye Quarry
At the entrance to the quarry the alarm calls of the Curlew that had greeted our arrival in spring was absent this time. Before climbing the small wall marking the entrance, we found the tiny white flowered Blinks (Montia fontana) hiding amongst the vegetation.

The path leading into the quarry had a trickle of running water and alongside the path were Oval Sedge (Carex leporina), Timothy (Phleum pratense), and Bog Stitchwort (Stellaria alsine).

Within the quarry we found Bell Heather (Erica cinerea), Great Willowherb (Epilobium parviflorum) and New Zealand Willowherb (E. brunnescens), Red Clover (Trifolium pratense) and Zigzag Clover (T. medium), Common Bent (Agrostis stolonifera) and Red Fescue (Festuca rubra), Lesser Trefoil (Trifolium dubium) and Bird's-foot-trefoil (Lotus coniculatus), Cat's-ear (Hypochaeris radicata), Mouse-ear-hawkweed (Pilosella officinarium) and Crowberry (Empetrum nigrum).

On the ground above a lake we noted Golden-scaled Male-fern (Dryopteris affinis agg), Common Sedge,(Carex nigra) and Pill Sedge (C. pilulifera), an occasional late flowering Common Centaury (Centaurium littorale), Tormentil (Potentilla erecta), Common Figwort (Scrophularia nodosa), Ox-eye Daisy (Leucanthemum vulgare), Yellow Rattle (Rhinanthus minor), Black Medic (Medicago lupulina) and Self-heal (Prunella vulgaris).

At the spring survey we had avoided intruding upon nesting birds around the small lakes, this time we found in the first lake Broad-leaved Pondweed (Potamogeton natans) and Bog Pondweed (P. polygonifolius) whilst Bottle Sedge (Carex rostrata) grew in the margins.

We then returned to the Digley car park were it was decided in the time remaining to survey around the reservoir.

Following the public footpath with agricultural land to the left and wooded slopes above the reservoir to the right and with dry stone walls providing a boundary, we noted Common Cow-wheat (Melampyrum pratense). A diversion away from the footpath, we climbed through a small ravine made by a feeder stream. In here was found Marsh Willowherb (Epilobium palustre), Lady-fern (Athyrium filix-femina), Hard-fern (Blechnum spicant) and Wavy Bittercress (Cardamine flexosa). Reaching the top of this ravine we then descended through a sheep field noting Silver Hair-grass (Aira caryophyllera) and Early Hair-grass (A. praecox), Prickly Sowthistle (Lactuca serriola), Crested Dog's-tail (Cynosurus cristatus).

Returning to the well trodden footpath which led to the dam wall of the upper Bilberry Reservoir, being a mid-point between the two reservoirs which providing an access to the opposite side of the lower but much larger Digley Reservoir.

On this wooded side of the reservoir where several small feeder streams entered the reservoir we found Common Hemp-nettle (Galeopsis tetrahit), Greater Plantain (Plantago major), Marsh Yellow-cress (Rorippa palustris), a Water Starwort (Callitriche sp.), Water-pepper (Persicaria hydropiper), Creeping Cinquefoil (Potentilla reptans), Marsh Cudweed (Gnaphalium uliginosum), Wood Sage (Teucrium scorodonia) and Marsh Bedstraw (Galium palustre).
