I have written before about laid hedges. Recently, I was actually doing it. The last time was back before I started the Volunteer Officer role but at this same reserve.
The hawthorns are all more mature than is really ideal. That said, using a chainsaw makes it possible to lay anything. But I was trying to use the traditional tools.

I had never used a billhook before and it took some getting used to. By the time I was starting to get the hang of it, I had to go - but I'd be returning the next day.
Before laying the hedge, we removed the wire fencing on one side and cut back the branches that stuck out over the fence line.
Then it was a case of nearly cutting through the trunks.

When just a sliver of living tree remains, you let the tree fall or guide it down into place.
Kate is very good at this. She is strong and more forthright about it than I am. Also I got distracted by a bark beetle and some woodlice exoskeletons. I gave then to Ian to inspect with his powerful microscope.
My slow pace and early exit aside, we made a good start on the first day.

The following day, we were able to see other aspects of this traditional land management craft. Once a good stretch of hedge had been laid, we could start to secure it.
Garry made stakes from hazel that had been coppiced nearby. They look deadly!
I really should have got Garry's head in. He has a nice head. Still.
These were pounded into the middle of the hedge at intervals of a forearm.

Then you use longer pieces of hazel as binders, to secure the stakes.
Dan says there are many different regional variations, but the benefits are consistent. Over time you get cattle-proof fencing that also provides a windbreak for the livestock. You encourage fresh growth in the hawthorn, and maintain a good supply of flowers and berries for insects, birds and mammals. And you provide safe nesting, resting and travel routes for wildlife.
You also get a good workout and learn new skills.
Finally, I was not injured.
And I made a video about it!
Super project and well described. Good video. I knew nothing about this method of fencing until you told me about it last year. Must try to use "billhook" in a scrabble game. New word to me. My gosh - just reading about the variety. Oh cool - I could get one locally (if I wanted to. Grin)
