In the Government's State of the Countryside 2007 report there is some encouraging news about arrests in species declines. However in the section on Environmental Quality, it says this of reptiles and amphibians:
"Evidence from biological indicators suggests that the situation has stabilised but at lower levels than several decades ago, and it may be some time before ecological improvements are clearly visible. Some measures suggest that where improvements have occurred, such as in river water quality, the more mobile species such as otters can make an effective recovery. It may take a lot longer and require active habitat restoration and reintroduction programmes to improve the situation for less mobile species such as reptiles and amphibians."
Gotta keep trying folks!
