We've just ordered 150 metres of stock fencing, fencing wire, and staples for the site. We're going to run a 90cm high stock fence along the road side boundary of the plot. The hedge is damaged and poorly maintained so the fence will provide some basic protection while we work on clearing the site and coppicing the trees. If we don't install the fence there's a risk that people especially local children and/or pets could enter the site to nose around. Normally this would be of no concern, but there will be some risks while work is in progress.
There's also a risk of farm animals straying on to the road during coppicing work along the embankment. While this work is in progress we'll temporarily dismantle the lower fence at the foot of the embankment, hence we need the roadside fence.
Longer term we plan to fully restore the roadside hedge by having it properly laid, but that process will take a couple of years. Once that process is complete we'll remove the stock fence at the roadside. The top edge of the embankment is mostly rubble from the road construction/maintenance process. It will be difficult to drive fence posts without causing damage. Where possible we'll use existing tree trunks in the hedge as posts for this "emergency" repair.
