Thanks for the link, I will have a look at this. Regarding the conifers, at the moment I don't know what type, they are all really tall and excude the light from getting down to the floor. All around the conifers are native broadleaf. I would be fascinated to know when and why the conifers were planted.Any idea what the conifers are?
