1 Report of four day field visit to Loch Tummel Pearl-bordered Fritillary Network using GPS, measure out the main clearings at various site compartments using GPS, measure out the main clearings at various site compartments take photographs of site compartments take photographs of site compartments assess need for management – scrub/tree clearance and bracken spraying assess need for management – scrub/tree clearance and bracken spraying make further habitat assessments such as abundance of dog violet if possible make further habitat assessments such as abundance of dog violet if possible By Dr Andrew Masterman 1 May 2008 Aims

2 Summary Western half visited on 26 & 27 March 2008 Western half visited on 26 & 27 March 2008 Eastern half visited on 2 & 3 April 2008 Eastern half visited on 2 & 3 April 2008 although time of year not ideal, south-facing bracken hillsides were clearly identifiable but dog violet was not easy to find in general but was fairly common at a few compartments although time of year not ideal, south-facing bracken hillsides were clearly identifiable but dog violet was not easy to find in general but was fairly common at a few compartments some large compartments (>10 ha) were found some large compartments (>10 ha) were found key feature of network is the west-east wayleave which comprised mostly steep, dry south facing bracken hillside key feature of network is the west-east wayleave which comprised mostly steep, dry south facing bracken hillside survey and photographs show the large extent of thick bracken litter and the need for bracken control along most of wayleave and around Tummel Bridge survey and photographs show the large extent of thick bracken litter and the need for bracken control along most of wayleave and around Tummel Bridge good habitat also present along stretches of north side of road and several north-south wayleaves link road to main wayleave good habitat also present along stretches of north side of road and several north-south wayleaves link road to main wayleave Largest compartments found in eastern half of site, particularly Bonskeid hillside but large areas of open habitat found south of river Tummel at Wester Clunie & Creag Torr Fionn.

The area he visited is now Holiday Homes. To the north of the holiday homes on the north side of the road, some good habitat ~ 100m deep merges with the wayleave but birch woodland is well-established here To the north of the holiday homes on the north side of the road, some good habitat ~ 100m deep merges with the wayleave but birch woodland is well-established here To the north of the wayleave, two large compartments were found. To the north of the wayleave, two large compartments were found. the first size 13 ha – Tummel Bridge Hillside - was south-facing bracken hillside bordered by birch & coniferous woodland but bracken litter was thick and dog violet not found. the first size 13 ha – Tummel Bridge Hillside - was south-facing bracken hillside bordered by birch & coniferous woodland but bracken litter was thick and dog violet not found. The second size 37 ha – Tummel Bridge Birch Woodland - was south-facing semi-open birch woodland with bracken and abundant dog violet. Birch trees were thin and straggly and close together ~ 1m apart. The second size 37 ha – Tummel Bridge Birch Woodland - was south-facing semi-open birch woodland with bracken and abundant dog violet. Birch trees were thin and straggly and close together ~ 1m apart. These compartments need to be revisited in May to confirm PBF here and if so, bracken spraying required in some areas. Perhaps birch clearance by holiday homes and at Tummel Bridge Birch Woodland. These compartments need to be revisited in May to confirm PBF here and if so, bracken spraying required in some areas.

32 Allean Forest Compartments There is a big gap in the conifer plantations above Strath Tummel associated with Tressait farm. Most of this area is intensively grazed by cattle and sheep and some is moorland. But there are some areas of good quality PBF habitat, mostly at Croft Douglas. Borenich site is probably too intensively grazed by cattle to offer good habitat but it is a south facing bracken hillside.

34 Tressait Pasture This area visited by Tom Brereton 9/6/97. This small pasture with bracken may provide a marginal pocket of habitat for PBF

58 Loch Tummel Pearl-bordered Fritillary Network East While the east-west wayleave which runs along the north side of the river Tummel is a feature, there are large extensive areas of south facing bracken hillside to the north and south of the river which are not wayleave-based. While the east-west wayleave which runs along the north side of the river Tummel is a feature, there are large extensive areas of south facing bracken hillside to the north and south of the river which are not wayleave-based. Bonskeid hillside is 157 ha but does contain areas of conifer plantations and grazed pasture lower down. This historically has been called Tenandry and parts of it visited by several recorders. In the east, it merges into Tenandry/Pass of Killiekrankie which has some habitat albeit semi-open woodland Bonskeid hillside is 157 ha but does contain areas of conifer plantations and grazed pasture lower down. This historically has been called Tenandry and parts of it visited by several recorders. In the east, it merges into Tenandry/Pass of Killiekrankie which has some habitat albeit semi-open woodland Just north of the river is Bonskeid Power lines which is a continuation of the main east-west wayleave and merges with some open birch woodland to the north adjacent to the road. Just north of the river is Bonskeid Power lines which is a continuation of the main east-west wayleave and merges with some open birch woodland to the north adjacent to the road. South of the river is Wester Clunie (amalgamation of Clunie Wood and Wester Clunie) which is 75 ha of open hillside (middle bit unsuitable habitat) with steep south facing bracklen hillside with dog violet in the north and south. South of the river is Wester Clunie (amalgamation of Clunie Wood and Wester Clunie) which is 75 ha of open hillside (middle bit unsuitable habitat) with steep south facing bracklen hillside with dog violet in the north and south. Just to the north is another steep south-facing bracken hillside (Creag Torr Fionn) size 16 ha where there are no PBF records so this appears to be a new compartment. This site is more birch woodland than open hillside. Just to the north is another steep south-facing bracken hillside (Creag Torr Fionn) size 16 ha where there are no PBF records so this appears to be a new compartment. This site is more birch woodland than open hillside. Cammoch is largely a gentle north-facing slope south of the river Tummel but it has small areas of south-facing hillside and is mostly open hillside and has large pylons. As there are several PBF records here, it may be important habitat although not the typical south-facing bracken hillside.
