DESCRIPTION

Dam Wood lies close to the Mulbuie Ridge, midway between Munlochy and Culbokie.

It is notified for lowland wet heath, springs (including flushes) and moths. The site is dominated by lowland wet heath which is crossed by numerous runnels and seepages emanating from the calcium-rich Old Red Sandstone rocks. These lime-rich habitats were once extensive in East Ross and Cromarty and Dam Wood is the largest of four such remnants.

The wet heath is dominated by ling Calluna vulgaris, bell heather Erica cinerea and cross leaved heath Erica tetralix. Purple moor grass Molinia caerulea is locally abundant. Of particular interest is the extensive population of Juniper Juniperus communis which occurs within the wet heath but also across the whole site. The plant communities associated with the flushes are markedly different from the wet heath and support a range of small sedges such as long-stalked yellow sedge Carex lepidocarpa as well as species more normally found in upland plant communities such as globe flower Trollius europaeus and alpine bistort Polygonum viviparum.

The site also supports the narrow-bordered bee hawk moth, a nationally rare species, and the chestnut-coloured carpet, a moth whose larvae feed on juniper.

VISITING DAM WOOD SSSI

The almost invisible access to the site is from a small parking area from which two tracks lead off. The southern track passes between woods before turning right towards the stile entrance to the site. On first glance there is little to be seen - just scattered stunted trees and a damp moorland hillside. The time to visit is late spring when the orchids and rarer flowers are in bloom, many by seeps of water. Waterproof footwear is sensible. There are no recognized paths - you choose how to avoid the wetter areas. The SSSI is owned by the Scottish Wildlife Trust and visitors will find they spend most time looking at the ground! At Dam Wood and Roskill SSSIs you get the feel of the Black Isle before much was made accessible for agriculture through drainage and soil improvement.

ENTRANCE TO THE SSSI
A reserve of the Scottish Wildlife Trust. See LinkExternal link. There were no cattle on the reserve during our July visit. The sign is rather historical. There is an interesting stile beside the gate. see NH6457 : Gate.

FLOWERING PLANTS
This area (within the Dam Wood SSSI) favours chalk-loving plants due to seepages emanating from the underlying calcium-rich Old Red Sandstone rocks: Very different from the acid soils found in much of the Highlands.

Living up to its name this was almost the only orchid species spotted at the Scottish Wildlife Trust Reserve. A visit in a few week's time should reveal more orchid varieties.

We only found one!

Grass of Parnassus is a perennial of peaty grassland, marshes and moors. A few examples were seen during an early August visit to the reserve.

The 20 hectare Belmaduthy Dam is an excellent example of wet lowland heath and mire mosaic, with lime flushes providing conditions suitable for a range of interesting plants. It was once a much more common habitat on the Black Isle, but much has now been replaced by agriculture or forestry. Underground springs in the nearby upper slopes of the Black Isle introduces nutrients to the otherwise poor ground, creating pockets of base-rich soil. The reserve is a Site of Special Scientific Interest.

This orchid was rather common across the Scottish Wildlife Trust Reserve.

FUNGI
Snowy Inkcap Fungi are strongly linked to dung, and in the Belmaduthy Dam Reserve of the Scottish Wildlife Trust cattle are stocked there for their role in conservation management. This image shows one stage of the life-cycle of the Snowy Inkcap fungus. The technical name of the fungus is Coprinopsis nivea. Different stages in the development of the Snowy Inkcap are here.

TREES
Belmaduthy Dam, a heathland with juniper, willow bushes and pine trees, is intersected by calcareous runnels in which grow black bog-rush, tawny sedge, carnation sedge, broad-leaved cotton grass and yellow saxifrage.  In June and July the site supports a profusion of orchids including twayblade, coralroot, early marsh, Northern marsh, lesser butterfly and heath spotted, as well as other lime-loving plants such as globeflower, northern bedstraw and grass of Parnassus.  The openness of the vegetation must be maintained by autumn grazing using a neighbouring farmer’s sheep or cattle.

Part of the Scottish Wildlife Reserve has seen significant natural regrowth in recent years. However in the open part of the reserve this Scots Pine has stood for many a year.

The Scottish Wildlife Trust owns this hillside on the Black Isle. Most land like this was tamed over the years to make farmland - this is the exception. This reserve is special because of the alkaline water that flows from deep springs onto the naturally acidic soil and this provides an unusual habitat. Highland Cattle may be seen on the reserve, playing their role in natural forest restoration. On this occasion none were seen.
See LinkExternal link for more information on the site and the suggestion to visit between May and August when orchids are abundant and nationally rare ones can be found by the observant.

GROUND TERRAIN MAY TO AUGUST
In the lowest corner of the reserve and abutting an old stone wall is an undisturbed moss bed that makes one wonder what lies below to give it such an distinctive topography.

It was difficult getting our dog through the boundaries of the woodland area despite a couple of stiles and locked gates. For more details of the Scottish Wildlife Reserve visit LinkExternal link.

This is a Nature Reserve owned by the Scottish Wildlife Trust and is well-known for its orchids.

Scrub juniper trees are a feature of the reserve,and here complete with berries is a young tree at ground level above a mat of lichen, probably cladonia portentosa.
