Writtle Wildlife Watch!

The face of the Essex countryside is forever adapting, with the arrival of new animal and plant species on a frequent basis. Farming is essentially changing too, with less livestock production and more arable crop farming. So why are we seeing these changes happen?

Conservation expert, Alan Roscoe, explores why...

"I was chuffed the other day to see that celebrity chef Tom Kerridge’s pub, the Hand and Flowers, serves a main course of ‘Essex lamb bun with sweetbreads and salsa verde’. With the notable exceptions of Kelly bronze turkeys, samphire from our estuaries and previously, saffron from the eponymous Walden, Essex is not especially venerated for the distinctiveness of its produce. So it was nice to see us given a mention.

It got me thinking though, about how geographically polarised our food production has become, with comparatively little livestock in the south-east, and how this has affected our wildlife. A lamb from Essex is a pretty rare - no pun intended - beast and I can think of only two farmers locally who raise sheep for the table. The exception proves the rule therefore. Essex is predominantly an arable county and has been for many years, mostly as a consequence of its soil being excellent for crops.

The presence of animals on a farm was, many decades ago, a given. They were there to provide the power to drive the plough and the harrow. With the arrival of mechanised power in the early 20^th century however, the presence of animals on a farm was no longer necessary and finding working animals on an Essex farm is now almost an impossibility.

So what is the knock-on effect?

Well, for a start, you no longer need grassland to feed your animals. And so called ‘unimproved’ grassland i.e. areas which have not had applications of chemicals or ever been ploughed, are especially rare. These areas have high conservation value and would have numbered among the fields which had fed animals for hundreds of years, only to be turned over to the plough once the animals were no longer needed.

But we also lose the animals and, arguably, their most important product – their waste. An ecosystem is built from the base up and, in many systems, we are talking about insects. Animal waste provides food and shelter, primarily for various families of flies and beetles. These insects then become a food source for small mammals, amphibians, reptiles and birds, thus acting as the base of    a huge ‘food pyramid’.

So although Tom’s lamb bun will set you back £27 a time, you are doing your bit for biodiversity in Essex!"
