Atholdale, A Limestone Valley

Synopsis: Atholdale is a valley in the carboniferous limestone plateau of Derbyshire. Investigates some of the differences in vegetation at various points in the valley and, with reference to three grasses (Deschampsia flexuosa, Arrhenatherum elatius and Festuca ovina) and three flowering herbs (Helianthehemum chamaecistus, Succisa pratensis and Centaurea scabiosa), examines some of the factors which cause their contrasting distributions. Some of the field and laboratory techniques employed by the Grassland Research Unit team are seen, including the results of growth and germination experiments and survey data of plant distributions from the surrounding area.

Notes: NB. As of May 2016 Open University Worldwide are no longer distributing DVDs. They have posted this message on their website: ‘Unfortunately Open University Worldwide Limited has decided that product sales are no longer viable given the reduced funding to Higher Education institutions and diminishing demand for the products we have traditionally stocked. At present the Open University Students Association (OUSA) will continue to sell the "Good Study Guide", and we are in discussion with other possible distributors to continue to make The Open University’s products available for purchase. As soon as we have any information on other channels of distribution we will update this notice’. Some products are still available via second hand dealers on Amazon.co.uk
