Hi Supersprout!
It isn't our site featured in the Garden Organic magazine but its good to know other sites are doing this too. And its something we'd recommend to other allotment sites, its ideal to plant on a perhaps awkward shaped plot (which ours is on).
Our hazel plantation is part of our wildlife area and we have several woodland plants (snowdrops, bluebells, wood anemones, violets, wood rushes) underplanted, plus a pathway through, so its a very attractive area.
