Re earlier comments:
Even more convincing would’ve been to undertake some survey work first, before attempting any kind of practical management!
Any competent or conscientious land manager (and especially on someone else’s property) would initially find out what was actually present: ascertain what habitat types (woodland, wetland, grassland, hedgerow, etc.) were represented; whether there were any notable or important plant and animal species /
communities there, or recorded in the past; any protected species (e.g. bats, barn owls, great crested newts, etc. etc.); ancient woodland; veteran or ancient trees, or any sites of archaeological / heritage interest. Otherwise any work undertaken could run the risk of damaging or destroying something already of value.
How would it be possible to come up with TW’s fabled ‘Biodiversity Plan’ for the farm, without deciding what the management priorities were, in the light of proper investigation and knowledge of the local nature conservation context?
Instead, the obviously clairvoyant SW constantly asserts in her press interviews and book festival tours that there was ‘no’ wildlife there when they arrived, that the farm was neglected and ‘dead’ (she must just ‘know’).
Miraculously, the following spring and summer, after reducing chemical inputs, clearing rubbish and a spot of dedicated differential strimming of grass, ‘weeds’ and bramble, biodiversity has been ‘brought back’ and the soil is healing.
Hurrah! Stuff the science, all you need for effective conservation land management is Psychic Sal and Mystic Moth to scatter their own particular brand of fairy dust over your property, and you’re sorted.
