Earlier this week at our local wildlife group Russell Parry gave an excellent talk on urban botany in Leicester. As part of this he discussed the frightening loss of plant species from the countryside and the concomitant(?) rise in urban species. As with all such changes, the causes are multifactorial, but one of the big drivers are management practices. In particular, one thing that Russell mentioned is the impossibility of replicating the Lammas system without appropriate winter grazing. No mowing regime can replicate the effect of light grazing over winter as this removes over-vigorous thugs, allowing delicate species to survive. Mechanical mowing is not a substitute as it cannot be carried out regularly through winter due to increasing rainfall, meaning the land is unavailable through flooding, or machinery cannot go on it without causing compaction (and loss of delicate species).
This has given me much cause for thought since I listened to Russell's talk. We struggle with our small urban perennial meadow, where the thugs take over in the blink of an eye and winter flooding (and compaction) is an ever increasing problem. My first thought was around Rentasheep - for a monthly subscription would-be meadowers take delivery of a sheep (and portable fencing, presumably an electronic system with a collar on the sheep) for a few hours a month. Leaving aside issues of animal welfare, it didn't take long to figure out that this would be prohibitively expensive, and to be honest I can't see a tribe of itinerant door to door shepherds arising anytime pre-apocalypse.
But there is a solution. Robot lawn mowers are all the rage and it wouldn't be that difficult for someone much cleverer than me to incorporate a slot for a mobile phone, so that with an AI image recognition appropriate app, a lawnmower with a suitable blade becomes an electric sheep (lightweight, although you could of course dial in the desired degree of poaching for optimum biodiversity in the same way that you set the cut height on a lawnmower). All the hardware and the software for this already exists, it's just a question of someone who cares enough stitching it all together. Surely it can't be long before I can pop into my local B&Q for a electric ovine (or mini-bovine)?
Electric sheep are not limited to my urban pocket handkerchief meadow - it's also a practical and affordable management solution for rural landowners, not to mention hard pressed Wildlife Trusts. Of course, with rural crime what it is, there will need to be a second generation or robot guard dogs to prevent the electric sheep being nicked ... or do I mean rustled? Electric lamb chops anyone?
