When I first saw in the recent Permaculture Magazine that Patrick Whitefield had written a book on reading the landscape I became very excited and thought, “That’s probably a book David Holmgren would have liked to have written!”
Holmgren called it “reading the great Book of Life”- looking at the living landscape of the countryside through the lens of ecology,botany, geology, archaeology, history and even politics and economics.
Observation of the natural world is the starting point of permaculture design and with this book Whitefield helps us gain an insight into the myriad of the many natural and human processes that make up our landscape, and how to interpret their hidden indications.
Patrick Whitefield covers all of these impacts on the British Countryside, taking his examples from all over the country, and shows us how to be a kind of landscape detective, painstakingly uncovering the meaning of signs and indications of past land-use, some obvious – the absence of trees indicating ongoing grazing- some much less so- the horeshoe bat indicating an intact mosaic of different habitats.
The book begins with some chapters on general patterns in the landscape and underlying features of geology, soil and then climate and natural succession before moving onto more specific cases including animal signs; niches; succession; Different Kinds of Woodlands; Grassland; Heaths and Moors; Water in the Landscape; and finally, Hedges and other field boundaries and Roads and Paths.
Throughout Patrick gives us pages from his extensive notebooks that he has kept over the years which show actual examples of reading the landscape in a wide range of landscape types he has encountered on travels up and down the country, from the Highlands of Scotland to the Somerset “Levels” – or Moors as they are more usually known locally; the remnants of diverse wildflower meadows still found on the chalk downs, and the semi-ancient wood of Lady Park Wood in the Wye valley.
Patrick is always an agreeable travel companion and makes fascinating observations throughout. The pleasure he takes at discovering new landscapes or unpicking the story of a woodland and how it got to have the species mix it has- the subtle interplay of geology, microclimate and grazing patterns- is always obvious, becoming most so when discovering a new hedgerow with large number of species ( a possible indicator of antiquity).
we have been using Patrick’s previous books, The Earth Care Manual and How to Make a Forest Garden on the Kinsale course for the past several years; The Living Landscape is another great addition which fills an important niche in permaculture literature. A fascinating and engaging read with great color photos, it will have to find a place on every designers’ bookshelf.
Taming the Dreaded Knotweed August 14, 2009
Posted by Graham in : Biodiversity, Environment , add a commentA new biological control is being considered as a way of controlling one of Britain and Ireland’s most pernicious weeds, Japanese Knotweed, according to this story in The Guardian.
a species of jumping plant lice, aphalara itadori, could bring down the mighty knotweed by guzzling its sap. If released to do its worst, it would be the first ever “biological control” deliberately introduced into Britain.
At present, knotweed can only be controlled with heavy-duty chemicals, and then only with great difficulty- it can remain dormant under the ground even after being cut for over a decade, and chews its way through concrete and tarmac for breakfast.
It is becoming a serious threat in Ireland however and there needs to be a concerted effort to educate how to stop its spreading. Take good note of the advice given in the above article:
And how to tackle it
• Don’t ignore it. A small Japanese knotweed plant quickly becomes a major infestation. • Do not strim, flail or chip it. It can reproduce from tiny fragments of rhizome, twig or even leaf. It is extremely unlikely you can eradicate it by digging it out, because the roots stretch down so deep into the soil. • Herbicides can check its growth but only the most powerful chemical treatments will eventually clear it. These are unsuitable for spraying near water. One approach is to allow the weed to grow to about 1m, in early summer, and spray then. You will need to re-spray regrowth in midsummer and again in September if necessary. Another approach is to cut it back and apply to the stumps a powerful weedkiller such as Roundup’s treatment for tree stumps and roots. • Be careful not to allow cuttings into any drains, streams or waterways. • Do not compost cuttings or put them in the rubbish bin. It is an offence under the Wildlife and Countryside Act to cause Japanese knotweed to grow in the wild so if you dispose of it carelessly you will be breaking the law. Do not dump it in the garden waste bin of your local recycling centre. Japanese knotweed (and contaminated soil) is classed as “controlled waste”, which means you must only dispose of it at certain, licensed landfill sites: check with your local council. If you are allowed to have a fire, burning the waste on site is another way to dispose of it. There are also commercial companies that specialise in the eradication of Japanese knotweed. • More advice at environment-agency.gov.uk
