Forestry - Facts & Statistics
•There
are over 40 million hectares of Forest Stewardship Council (FSC)
certified forest and woodland in 59 countries world wide. In the
UK we have over 1.1 million hectares of FSC certified forest.
•There
are more forests and woodlands in the UK now than for a long time.
Woodland area has been steadily increasing since 1920, just after
the Forestry Commission was set up. There are now 2.807 million
hectares of woodlands in the UK, or 11.6% of the land area. Despite
more than doubling tree cover in the last 100 years this is still
less than all our European partners except the Netherlands and Eire.
•Forests
in other European and other developed countries are also expanding,
but forests in many tropical countries are still shrinking due to
conversion to agriculture, cattle ranches or plantation crops like
oil palm. Political instability, war and conflicts give opportunities
for illegal exploitation of tropical forests. Loss of tropical forests
is especially serious as they contain more types of plants and animal
than any other ecosystem on land.
•There
are almost certainly no natural woodlands in the UK. All have been
affected and managed by people, often for thousands of years. Ancient
semi-natural woodlands (ASNW) are woods that have existed on a site
since 1600 or earlier. Some are much older and may be direct descendents
of the original wildwood. ASNWs contain a rich diversity of woodland
plants and animals and maintaining them is vital for biodiversity
conservation.
•Coppicing,
the periodic cutting of trees to ground level to produce small sized
poles, is an ancient art. timber recovered from bronze age roadways
in Somerset indicate it came from a coppiced woodland. Coppicing
rejuvenates trees too and allows them to live longer than normal.
Some coppiced ash trees are estimated to be over 800 years old.
•Coppicing
is good for butterflies and other plants and wildlife. The Forestry
Commission’s recent Coppice Challenge showed that re-starting
resulted in a rapid increase in the species and number of butterflies.
Continued coppicing in an area reinforces these benefits for biodiversity.
•In
the UK we burn between 45,000 and 55,000 tonnes of charcoal each
year on our barbeques, depending on the summer weather. Yet the
Forestry Commission estimates that only 5,000 tonnes a year of charcoal
is made here.
•Charcoal
imported to the UK comes may have travelled 12,000 miles or more
to get to your barbeque. Most comes from South Africa, Brazil and
Nigeria. BioRegional aim to have local charcoal made within 30 miles
from where it is sold.
•London
produces almost 100,000 tonnes a year of tree waste (estimates vary
between 54,000 upwards). If it were all used in combined heat and
power plants (CHPs) around 10MW of electricity could be generated
along with useful heat. That’s enough power and heat for 22,000
homes . There are also other sources of waste wood which could be
used as fuel. Other urban areas around the UK produce similar quantities
of tree waste which could be used as fuel.
