Research linking rare aquatic plant distribution and palaeoecological data presented at IPA-IAL 2018 conference, Stockholm, Sweden.

Professor Helen Bennion presented some of our NERC Hydroscape research at the joint meeting of the International Paleolimnology Association and the International Association of Limnogeology, Stockholm, Sweden, June 18-21, 2018 (see site).

Some of the research highlighted during this talk concerned the distribution of Elatine hydropiper (eight-stamen waterwort) in the Glasgow area. This aquatic plant is extremely inconspicuous and can grow at great depth underwater. Because of these characteristics it is believed to be very under-recorded by botanist and aquatic monitoring alike. It has also been hypothesised that it may be becoming more frequent, especially in Scotland. However our research demonstrates that in the Glasgow area, Elatine hydropiper was present in the 1850s at four lake sites out of eight investigated and became extirpated at two of these sites during the twentieth century. This shows that it was more widespread in the past and that more effort towards conserving suitable habitats for this aquatic plant should be undertaken.
