I paid a visit, a few years ago, to Cannock Chase during the breeding season to just have a mooch about during the day. Whilst i was there i bumped into somebody who was censusing the Woodlarks. Whilst watching a displaying bird i had a chat to the bloke. At the time i think there was an estimated 25+ pairs minimum. Habitat-wise he said that the present Forestry Commission management for the spp was proving successfull. They were felling blocks of 15-year old conifers and then just brashing them were they fell. This left a level of branches, twigs etc about a metre high. This was then colonised by bramble etc. The odd, isolated, tree was left as song perches and the birds readily utilisted the fallen brash as nesting habitat presumably finding bare areas in between. This had the advantage of providing cover and protection from predators and dog-walkers.
