Shimrod, I wasn't actually asking if anyone wants a yew sapling.
Err, that was kinda tongue in cheek.

Otherwise, there are a lot of urban spaces I see around me - including council estates - where a few trees might possibly be a nice idea.. A couple of apple trees might even be nice on the village green (though it would put out the people who like to use it as a car park). But I'm not about to go about creating vast plantations of conifers (I think that's the 'forestry commission's speciality) on local heathland where some rare species of wild orchid is being preciously preserved, so there's really no need to fret!
