sustainability
small- scale timber production
Uses techniques such as coppicing
Tree trunk is cut close to the ground
New shoots form from the cut surface and mature
Eventually these
shoots are cut
and in their place more are produced
rotational coppicing
is used in mosed woodlands
Helps to
maintain biodiversity
as the trees
never grow enough
to
block out the light
An alternative technique to coppicing is pollarding which cuts the trunk higher up so deer and other animals can not eat the new shoots
large-scale timber production
based around the technique of f
elling large arears of forests
Timber companies
practice selective cutting only
removing the large trees
They also replace trees through
replanting
rather than waiting for
natural regeneration
They also plan trees an optimal distance apart to
reduce competition
Manage pests and pathogens to maximise yield
Sustainable fishing
Overfishing
has led to the
populations
of some species of fish
decreasing significantly
They are then unable to regenerate
To
overcome
this problem international agreements are made about the
number of fish that can be caught
