"Ability to see the cultural value of wilderness
boils down, in the last analysis, to a
question of intellectual humility. The shallowminded modern who has lost his
footage in the land assumes that he has already
discovered what is important...."
Aldo Leopold, A Sand County Almanac

1. Re-wilding (cont’d)

Two basic approaches:
- "letting go“
• if a landscape is left unmanaged for a long
enough period, nature will take over and
produce its own entirely natural landscape
• may not necessarily be the same landscape
that existed before human settlement, but it
will be natural
- "wild by design“
• we may need to actively 'design' wild
landscapes by assisting the regeneration of
native species to recreate a more natural
looking landscape
• limited economic activity in the form of low
intensity grazing and recreation is still
possible and indeed desirable
• E.g. Council for National Parks (1998)

1. Re-wilding (cont’d)

Developing new wild lands where
opportunities arise
- Edwards Review (1991)
- CNP “Wild By Design” (1998)

Aspects of re-wilding
- promotion of wilderness qualities
- enhancing and recreating semi-natural habitats
- promotion of ecological process in near-natural
areas


Lecture 7
Edwards Review (1991)
“a number of experimental schemes on a
limited scale should be set up in National
Parks where farming is withdrawn
entirely and the natural succession of
vegetation is allowed to take its course”
(Recommendation 6.3, Edwards, 1991)
GEOG3320 – Management of Wilderness Environments

“Wild By Design”


Lecture 7
Semi-natural areas, which appear natural
but are in fact influenced by management
for agriculture or forestry.
Near-natural areas, where the land is
totally divorced from agricultural or
forestry use – in which natural processes
are encouraged to maintain the diversity
of habitats, and vegetation is free to vary
naturally with variations in the physical
environment. (After CNP, 1998, p.3)
GEOG3320 – Management of Wilderness Environments
9
1. Re-wilding (cont’d)

Promotion of the wilderness qualities
- while maintaining productive use which
may best be applied to semi-natural areas
- in accordance with the aims of the UK
Biodiversity Action Plan (BAP) to conserve
and enhance biological diversity
Lecture 7
GEOG3320 – Management of Wilderness Environments
10
1. Re-wilding (cont’d)


Enhancing and recreating semi-natural
habitats and recreating others
For example:
- reducing grazing pressure to allow vegetation to
-
Lecture 7
develop more naturally
enhancing and restoring natural features such as
river restoration schemes
restructuring specific landscape elements such as
conifer plantations to give a more natural outline
GEOG3320 – Management of Wilderness Environments
11
1. Re-wilding (cont’d)

Promotion of areas where ecological
processes can be paramount
- especially in near-natural areas where relatively
large areas of land can be left without
management for long periods of time
Lecture 7
GEOG3320 – Management of Wilderness Environments
12
Question:
What is the current basis
for re-wilding in Britain?
Lecture 7
GEOG3320 – Management of Wilderness Environments
13
1. Re-wilding (cont’d)

Environmental resilience
- how does (re)wilding fit with this
approach/view?
- drivers for change
• social, environmental, economic
- factors influencing environmental
degradation and landscape response
• robust nature vs delicate balance
• landscape and public perceptions
Lecture 7
GEOG3320 – Management of Wilderness Environments
14
1. Re-wilding (cont’d)

Environmental drivers
- climate change and ecological response
• shifting patterns of migration and range
• N-S movements and altitudinal shifts
- changing geographies of nature
- humanistic barriers to adaptability
• lack of space/continuity between wild areas
• pollution (critical loads) and environmental
stress
Lecture 7
GEOG3320 – Management of Wilderness Environments
15
1. Re-wilding (cont’d)

Policy drivers
- CAP reform and changes in agricultural
subsidies paid to farmers
• over-production/over-grazing
• environmental stewardship
• agri-environment schemes (fitting in)
- habitat Directive
• Natura 2000
• Biodiversity Action Plans (BAPs)
• Water Framework Directive
Lecture 7
GEOG3320 – Management of Wilderness Environments
16
1. Re-wilding (cont’d)

Economic drivers
- CAP reform and the single farm payment
- agricultural ‘disasters’
• FMD
• BSE
- falling prices and the power of the big
-
Lecture 7
supermarkets
increasing proportion of rural economy
based on tourism and recreation
GEOG3320 – Management of Wilderness Environments
17
1. Re-wilding (cont’d)

Social drivers
- rise in outdoor recreation and leisure time
- greater mobility and disposable income
- rural migration:
• in migration of retirees and commuters
• out migration of farm workers, etc.

GEOG3320 – Management of Wilderness Environments
19
1. Re-wilding (cont’d)

Various strategic projects:

The Wildland Network
- LUPG’s “New Wildwoods Project”
- RSPB’s “Futurescapes”
- new umbrella organisation
- objectives:
• To promote the recognition and appreciation of wild
land
• To protect and conserve the qualities of wildness
• To promote the establishment of complete
ecosystems on a large scale, through research,
advice, encouragement and education

1. Re-wilding (cont’d)

The next steps?
- “Wild by Design” highlights the
challenge…“the commitment to leave minimal
intervention areas on a much larger scale (landscapes of
thousands of hectares) and over much longer periods
(hundreds of years)” (CNP, 1998)
- integrating re-wilding with farming
• “Wilderness and Plenty” Fraser Darling
- packaging and marketing
• selling idea to public and politicians
- developing a workable and realistic
strategy
Lecture 7
GEOG3320 – Management of Wilderness Environments
21
2. Re-introductions of
native species

Nature management in UK?
- maintaining habitats and species
- remnants of former farming/forestry
systems
- management using past practice
- i.e. “nature gardening”

Lecture 7
Alternative systems?
- less human intervention
- role of large herbivores and predators?
GEOG3320 – Management of Wilderness Environments
22
2. Re-introductions of native
species (cont’d)

Herbivores as a management tool?
- NOT a unit of production (e.g. farm
animals)
- Vector of ecological maintenance
• “shaggy gardeners” or “woolly mowers”
• prevent tree regeneration on heaths
• Maintain short grass sward on chalk down
Lecture 7
GEOG3320 – Management of Wilderness Environments
23
Question:
What are the key issues when
considering use of large
herbivores as a tool in rewilding projects?
Lecture 7
GEOG3320 – Management of Wilderness Environments
24
2. Re-introductions of native
species (cont’d)

What are appropriate populations?
- carrying capacity?
- relationship between animal numbers and
pattern and structure of vegetation?
- species type?
• grazers vs browsers vs foragers
• preferred fodder
• niche habitats (e.g. beaver in riparian zone)
- predation and demographics?
- The “herbivore guild”
Lecture 7
GEOG3320 – Management of Wilderness Environments

“herbivore guild” for Britain?

to dense forest)
• cold adapted

Wales
• sufficient prey and habitat
