Exposed riverine sediments (ERS) are habitat for a large number of rare and threatened specialist species of invertebrates and are of considerable conservation importance. Livestock trampling is believed to be one of the most widespread causes of damage to ERS habitats in the UK, and as such, its effects were the focus of this investigation. Beetle density was measured at two points within 25 distinct patches of habitat along similar to 47 km of the Afon Tywi special site of scientific interest in South Wales, which is known to support an extremely good quality ERS beetle fauna in a UK context. Partial canonical correspondence analyses were used to explore the relationship between beetle assemblage and a range of environmental variables. The percentage of fine (
