The common toad (Bufo bufo) has undergone recent declines within the UK and despite being added to the UK Biodiversity Action Plan in 2007 the cause of their decline is yet to be identified. One cause for concern is the fragmentation of populations due to increasing urbanisation and road traffic. As urbanisation and agriculture has increased across the country B. bufo populations have become increasingly isolated and unable to interact which may be causing populations to become inbred and decline. This study looks into B. bufo populations across Anglesey and mainland North Wales. Toads have been sampled via buccal swabbing and using microsatellite analysis the level of heterozygosity within populations.
Using this research we can develop conservation strategies such as increased green corridors and road tunnels to prevent the UK common toad from declining even further.
