Researchers (Stephen Thomas) at Cardiff University have recorded significant reductions in insect numbers in the Rivers Wye, and Tywi, and indeed one local extinction - these are associated with our changing climate.
Trees clearly offer shade to rivers and streams and this is important in mitigating the effects of high temperatures. As water warms so the level of dissolved oxygen falls. However, trees also help the resilience of these freshwater systems Read more...
