Evolution of the rural landscape of Great Britain
All about meanings
In reverse order:
• Great Britain - why the geographical restriction?
• Landscape - what does it really mean?
• Rural - what does that mean?• Evolution - can a landscape evolve?
Great Britain: the major island of the archipelago of the British Isles
• It is home to most of us
• It is an island• Its landscape has a
recognised “starting point”
• It has some of the most varied landscapes in the world
During the last Ice Age
• Britain and Ireland part of continental Europe
• Most of the “country” under kilometres of ice
• The ice retreated approximately 10,000 years ago
• The land was scraped clean rock
10,000 years agomodern people arrived
• Sea levels rose +100m• Ireland became an
island first and still has far fewer native species as a result
• Great Britain was populated by Neolithic hunter-gatherers
• The English Channel cut off Great Britain around 8,000 years ago
• Great Britain approximately 5,000 years ago
• A forested island with a very small population of hunter gatherers.
• This “wildwood” is considered the “natural state” of the British landscape prior to the arrival of agriculture
After Rackham 1997 p 34
Wildwood no longer exists in Great Britain
Bialowieza National Park, Poland
• Agriculture changed everything
• European agriculture grew from its invention in Iraq around the end of the Ice Age in northern Europe
• It arrived in Britain around 6,000 years ago, after it became an island
• Southern Britain became one of the major grain and wool producing provinces of the Roman Empire
• The basic nature of the current British landscape was established then.

The British Landscape
• Naturally forested• Heavily modified by human activity
– Clearing– Cropping– Grazing– Draining– Building…
What does Landscape mean?
• Some general definitions– an expanse of scenery that can be seen in a single view – painting depicting an expanse of natural scenery – an extensive mental viewpoint; "the political landscape
looks bleak without a change of administration
• Scientific definitions:– Any combinations of ecological, environmental and
geographical systems which are in equilibrium. Combinations of plants, animals, climate and geography which are only found in certain places and not elsewhere
• None of these is what we mean when we talk about landscape management.
Characteristic landscape
• In the context of land management, landscape can be defined as:
– A contiguous area of land of any size which has common characteristics throughout its extents which distinguish it from other areas of land.
Types of characteristic landscapes
• A characteristic landscape usually has a qualifying descriptor, e.g.– a forest landscape– an industrial landscape– a pastoral landscape– a polluted landscape
Defining the landscape character
• All land is part of one or more landscapes– An area of cultivated land in Wales might be
seen as part of a farming landscape and of a mountain landscape
• A land manager is usually predominantly interested in one character landscape
• You will be primarily interested in the rural landscape
What does Rural mean?
• Countryside?• Farmland?• Forests?• In America: officially areas with less
than 250 people per km2
• OED “in or of or suggesting country”

Landscapes are not simple, nested shapes
Rural landscapes
• Managed, non-urbanised landscapes– Agriculture– Forestry– Grasslands– Moorlands– Water collection– Small built areas– Transport networks
Can non-living landscapes evolve?
• Some definitions of evolution– A gradual process in which something changes into
a different and usually more complex or better form – The process of developing– A movement that is part of a set of ordered
movements
• Systems subject to selective temporal change– Some changes are successful and lead to further
change– Some changes are unsuccessful and lead nowhere
Landscapes do evolve
• Landscapes change over time• Natural selection would result in Great
Britain returning to its primeval forested state
• Human selection, often unwitting, results in the varied, changing landscapes we see today
• Landscape management is the intentional, professional attempt to manage that selection process
The evolution and perception of the rural landscape of Great
Britain
