Cup and ring mark stone A type of
petroglyph called a
cup and ring mark stone is recorded as existing at Dalgarven by John Smith, the notable Ayrshire antiquarian. Unfortunately the exact whereabouts of the stone is unknown; however a copy has been produced and is on display in the grounds of the mill. The purpose of cup and ring marked stones is unknown. The carvings on the original stone would have dated from the
Neolithic or
Bronze Age times, being as old as 6000 years. This Dalgarven example is unusual in having cups and connecting toughs, but no rings. Often up to five concentric rings are found circling the central cup.
Fossils Fossil-bearing
limestone boulders are sometimes found in the river with fossilized
tree fern roots and imprints of the trunk. These represent long-extinct plant species which grew to an impressive height compared to their modern relatives which only reach a few feet. Millions of years ago these plants thrived in a warm and hospitable climate and gave rise to much of the Scottish
coal deposits.
Riverside walk Visitors should leave time to wander through the unspoilt landscape formed by the gently flowing
River Garnock. In spring, the wild flower meadow is at its best, in summer, sit by the riverbank and watch the heron, swallows,
kingfisher and other wildlife. A Community Woodland has been established and the site is open access. The gravel bed of the river was an important source of income for the millers, for through the estate they had sole right to the extraction of the gravel here, which was sold for various farm and horticultural purposes. The meadows are particularly rich in pignut (
Conopodium majus), a relative of parsley, which formed a breaktime snack for children in former times. If the plant is dug up a small potato-like structure is found which when eaten raw has a slightly nutty taste. It is available commercially for salads, etc.
Hemlock water dropwort grows well in the wetter areas and is best left alone as the name
hemlock suggests. The large leaves of the butterbur (
Petasites hybridus) are found in several areas; its name harkens back to the days before clingfilm or cheap paper when the leaves were used to wrap butter destined for the market. Water ragwort (or Saracen's ragwort) (a species of
Senecio) is an introduced plant which grows along the riverside in tall stands. It is common on the Garnock and at present quite rare elsewhere.
Himalayan balsam or policemen's helmets is another introduction, but a common one.
Giant hogweed is beginning to make its presence felt. It is another plant which should never be handled as the sap can cause severe blistering and scarring of the skin. Ayrshire Rivers Trust are a local conservation charity that have been highly effective controlling invasive weeds in Ayrshire and are soon to tackle giant hogweed on the Garnock and other rivers in North Ayrshire. More information on the work of the Trust is available through their website at www.ayrshireriverstrust.org The Stewarton flower or pink purslane (
Claytonia sibirica) is common in wetter areas. It has white or pink flowers at this site, but closer to
Stewarton it is almost always white. It seems that it was first introduced as a white variety in the Stewarton area in Victorian times and the common pink variety, introduced later, spread to other areas. Dalgarven, it seems, is on the edge of the white flower zone of dominance. Dalgarven is the only known site for the pocket plum gall (
Taphrina padi) which develops on bird cherry.
Coppicing of the riverside
alder trees is still carried out. Alders grow well in wet soils and are specially adapted for the low nutrient conditions through having large root nodules containing nitrogen-fixing bacteria which enrich the soil in the same way as clover plants and other legumes. The many hedgerow trees in the vicinity of the mill were not planted by farmers for 'visual effect', they were crops and the wood was used for building and fencing. The miller needed
beech or
hornbeam wood for mill machinery, in particular the cogs on the drive wheels from the waterwheel. It is not generally appreciated how much the Ayrshire landscape has changed its character over the last few hundred years, for even in the 1760-70
Statistical Account it is stated that "there was no such thing to be seen as trees or hedges in the parish; all was naked and open". or Green Figwort - the mill's rarest plant species.
Countryside walks and the Sustrans cyclepath The
Sustrans cyclepath from Irvine and Largs to Glasgow runs close nearby and cyclists often drop in for refreshment and a look around before heading up passed the Blair Estate and then along the old Lochwinnoch railway line via the
Clyde Muirshiel Regional Park to
Johnstone,
Glasgow or Kilmacolm. The Dusk Water joins the Garnock at Dalgarven and one of Ayrshire's most interesting natural curiosities,
Cleeves Cove cave system in the Dusk Glen, is within walking distance via Cockenzie and Auchenskeith farms.
Blair House Until recently the home of the Borthwick family, Blair House, is nearby and had a long tradition of allowing public access to its grounds. It was said to be the house with the longest continuous occupation by the same family in Scotland until the family sold up in 2012. == Notes==
