Nettles and ancient human habitation
July 3rd, 2009 | by Nick |
Stinging nettles can give away secrets of our past. They have a strong association with human habitation and buildings. This is because our waste of refuse, ash and bones is rich in phosphate, which then builds up in the soil, and stinging nettles love phosphate. Phosphate can stay in the ground for a very long time in non-acid soils, and as a result their presence may indicate the existence of long abandoned settlements.
Richard Mabey wrote in Flora Britannica, which I must buy:
“Human settlements provide phosphates in abundance, in cattle-pens, middens, bonfire sites, refuse dumps and churchyards.” Even long-abandoned human habitations continue to have nettles growing around them when there might not be any other nettles for miles, according to Mabey: “The wooded sites of Romano-British villages on the Grovely Ridge near Salisbury are still dense with nettles subsisting on the remains of an occupation that ended 1,600 years ago.” From nice article here
Another example of nettles and settlement abandonment is the large clumps of nettles around the sites of Scottish crofts which were razed to the ground during the Highland Clearances.
The next time you see a large clump of nettles, you might want to imagine what lies beneath them.

The RSPB is gathering extensive information about exactly where swifts are nesting in the UK. It is suspected that their rapid decline in recent years is linked with a drop in suitable nesting sites, as buildings are modernised.
The first year’s survey reveals that of the houses where swifts are nesting:

With more and more people wanting to grow their own fruit and vegetables, the National Society of Allotment and Leisure Gardeners have over 100,000 people on their waiting lists. The National Trust have responded to this demand by allocating land for “super allotments” or community farms. In return for a monthly fee, members will decide what should be grown, and have the opportunity to work on the farms, receiving a share of the produce.
