The limestone habitats of the Yorkshire Dales National Park harbour many species characteristic of base-rich conditions. Such calcicole species as blue moor grass (Sesleria caerulea), birds-eye primrose (Primula farinosa) and limestone fern (Gymnocarpium robertianum) are typical of many sites around Malham. This course aims to explore this specialist flora amid the magnificent Craven scenery. We will visit a variety of local habitats to gain experience of using keys and identifying a wide range of species in the field. We will concentrate on several important plant families including ferns, grasses and sedges.
The emphasis during the day will be on identification in the field and a proposed programme for this includes:
Friday: Walk up to Highfolds (behind Centre) after supper for limestone pavement and views.
Saturday: Grassington for limestone woodland and grasslands.
Sunday: Limestone pavements around Ingleborough NNR.
Monday: Base-rich mires and fens at Malham.
Evenings will mainly be spent in the classroom to practise using keys, use microscopes to help confirm the identification of a few more difficult species, and understand why limestone supports such a specialist flora.
