i feel your anger OCP - it is so annoying when somebody decides to "help themselves"
please don't take this the wrong way - but you may have yourself to blame
this is an open forum - read by anybody - anywhere - it's great that we can chat about the ins and outs of owning a woodland but i think you need to be wary posting specific details
you have said where your woods are - probably mentioned what kit you have on site - even chatted about security / lack of it - you also advertised to the world - that you were not going to be around that much over xmas/new year - because of the pup etc
there are many more nasty (than nice) people out there in the big bad world - and i expect a good few of them have access to the internet - so don't tell them what you've got, where you keep it and certainly don't tell them when you aren't going to be there.
