A new(ish) series of this is currently being broadcast, under a new nom de plume, "Rhys Jones's Wildlife Patrol", with a slightly greater emphasis on wildlife crime.
Both Rhys Jones himself, and the policeman you mostly seeing him working with, PC Mark Goulding, are good presenters, and come across as though they've been trained to do a TV programme (maybe they have!).
It's slightly depressing, when you see the clearly dodgy scrotes that they obviously regularly have to deal with, getting away with conditional discharges or minor fines, but at least they're being caught, and held accountable to some degree.
Definitely worth watching, always interesting programmes. There are currently all three of the current series on iPlayer.
