Mount Cargill is a 676-metre-high volcanic hill dominating North Dunedin. The upper slopes are clothed in regenerating cloud forest and shrubland with their associated communities of bryophytes and lichens. We willstart from Bethunes Gully at the end of Normanby Street. There is a good walking track that initially passes through exotic forest which then gives way to mixed podocarp/broadleaf forest on the mid slopes. This in turn is replaced by low forest containing a variety of species including Griselinia littoralis, Dracophyllum longifolium, Olearia ilicifolia and Coprosma foetidissima on the upper slopes. On the northern side of the ridge is a patch of mature forest with emergent Libocedrus bidwillii. Depending on the weather, as the ridge crest is rather exposed, we will explore these different communities. Another feature of interest is the hexagonal basaltic columns that outcrop below the summit. Meet at the Botany carpark at 9.00 am. Bring lunch, warm clothing, good footwear and parkas. Finish time about 3.00 pm.
