This course introduces and deals with the differences between the grass, sedge and rush families and their identification. It is aimed both at beginners and those, including professionals, who wish to improve their existing identification skills. The use of Keys will be introduced as the course progresses. The diversity of habitats in and around the National Park mean field visits to both upland and lowland sites are intergrated into the course. Particpants will visit Migneint Moor, or similar upland environment in Northern Snowdonia, which will contrast with visits to lowland meadows around Penmachno and Llanrwst. Although much of the recognition will be learnt in the field, evenings sessions in the lab will be used to discuss the days findings and for looking at certain features in more detail.
