As part of the grouse management, the estate appears to have set a large number of rat-traps on logs across water features. Basically a large version of a conventional mouse-trap, it sits on top of the log, and activates when a rat touches the trigger plate. We saw about 3 dozen of them in the course of a day's walk; not one had been sprung, which suggests either that all the rats have been eradicated, or that they're wise enough not to use the logs.
