The loss of arable plants

The loss of arable plants

Recently the blog commented on the loss of wild flowers from country lanes and roadsides - occasioned by seeing nettles and cow parsley for miles, and very little else.  This loss of diversity may be attributed in part to the use of nitrogenous fertilisers and aerial deposition of pollutants.  It is 'rare' to see poppies around the edges of fields nowadays.   So what is happening ?

Obviously, the seed used by farmers nowadays has fewer "wild contaminants" but Plantlife is concerned that various agricultural management practices have placed arable plants under threat.  The need to make economic use of every bit of land, the increased use of herbicides (to control pernicious weeds - such as charlock, black grass, sterile brome) has a knock-on effect on many arable wild flower species, as has the greater use of winter planting.   In some parts of the country, a switch away from arable farming has also had its effects.

Some 150 wild flowers are characteristic of,  or associated with arable farming;  many are now threatened.  The majority of the 'uncommon species' are found in the south-east (crudely speaking - draw a line from the Wash across to the Bristol Channel) [full details available in a pdf from Plantlife ].  Some areas have a particularly rich flora - South Cambridgeshire, the Breckland of Norfolk and Suffolk.  Red hemp nettle, cornflowers, pheasant's eye, corncockle, corn marigold, fumitories, prickly popppies are examples of these arable / farmland species.    Many of these farmland plants are important sources of food for insects, seed eating birds and mammals.  The yellow hammer and the linnet are examples of birds that depend on such seeds during the winter months.

Farmers are being encouraged to create borders to their fields where such species can again flourish - many arable plants are annuals and are well suited to regular ploughing and ground disturbance (either in Spring or Autumn depending on the germination time).  As some annual seeds can persist in the soil for decades [the seeds of rough marsh mallow are said to persist in the ground for 180 years] , the cultivation of the field edges will give an opportunity for these species to 'come back' from seeds that have laid dormant in the soil for many years (seed bank).

A number of agri-management / environmental stewardship schemes are available, to quote from Natural England  "Environmental Stewardship is an agri-environment scheme that provides funding to farmers and other land managers in England to deliver effective environmental management on your land".

Until Humans begin to see the countryside as an extension of themselves and their own bodies as some do, I’m afraid nothing will change. They always seem to want to ‘DO’ something rather than just let nature be and appreciating it as it is? In my own garden I wouldn’t dream of using chemicals and artificial things, as I have created a complex ecosystem that doesn’t need it. Until people apply the same (supposedly ‘old fashioned’ eco- law) to the land.

As soon as I have the money, I will buy some woodland just to keep it safe from the ravages of certain humans!

[…] The build-up of soluble forms of nitrogen, particularly nitrate, in water is a concern since high concentrations in rivers, streams and lakes promotes eutrophication, and high concentrations in drinking water are a concern for health reasons.  The diffuse contamination of woodlands and roadsides is thought by some to encourage ‘nitrophiles’ or nitrophytes – plants, like nettles, that can use and exploit a nitrate-rich environment to the virtual exclusion of others.

Radnorshire Wildlife Trust has a successful Roadside Verge Nature Reserve project, and have provided a plant identification poster.
Only a side mention currently on the website (http://www.rwtwales.org), but I’m sure they would provide past reports if asked.

I’m afraid that even the cow parsley and nettles aren’t allowed here in West Sussex. The verges are mown several times a year and are now looking like a lawn. The verges are cut right in as far as possible, so even the excuse of visibility for motorists doesn’t wash. It is a tragic situation, destroying acres of native British flowers and a whole eco-system for wildlife. It would seem that mankind has an insatiable appetite for so called tidiness. Maybe we could set up a campaign to “Save our Verges”.

Volunteer Offer
I live in Tunbridge Wells Kent and would like to volunteer my time in helping with this work as it is essential to sustain a healthy ecosystem. I would however ask for my costs to be covered and a small daily payment (national minimum wage) so that I can sustain myself! So if you live nearby and need a hand please do get in touch.

Kind regards
