Of course, none of you need me to tell you that, no matter how many extra trees you put in your 'compensatory plantation', a sapling is not going to attract birds to nest in it for 40+ years, the absence of leaf litter means that the worms and ground-level insects have nothing to eat or hide in, so all the larger animals which might eat them won't be showing up for a few decades either.
Indeed, the individual creatures whose habitat you're about to chop down cannot simply disperse into the bits of woodland left behind - because those territories are already taken by others of their kind - and they have no way of knowing where your replacement plantation (which isn't going to be ready inside their lifespan) is, anyway.
So, plant your forest, give it 50 years to establish itself and then we'll be more inclined to let you chop things down without a protest.
