Impact Assessments:
We produce tree reports
for planning applications
and for checking the
effects a development
may have on any trees
that are close enough
to be effected. These
are produced in accordance
with BS5837:2005 'Trees
in Relation to Construction'.
We can provide drawings
as part this service
or work from other
peoples.
Quantified Tree
Risk Assessment:
We are also licenced
to use a tree risk
evaluation system
called Quantified
Tree Risk Assessment
- QTRA.
This system takes
into account the various
factors which effect
the probibility of
harm to peaple or
property occuring,
due to tree failure
(branch failure, Stem
(Trunk) or Windthrow).
A figure such as 1:1000
is produced as a guide
and the customer can
decide themselves
wether this risk is
acceptable or not.
Large organisations
often already have
an acceptable risk
policy with a figure
normally set between
1:10,000 and 1:20,000.
The report will include
measures which can
be taken to reduce
or remove risk. It
can be applied to
large numbers of trees
quite quickly, or
in more detail to
individual trees.
We can also provide
a more basic Tree
Hazard Evaluation.
Tree
Thermal Imaging for
Decay Detection:
We are licenced to
use this new technology
for assessing the
extent of decay and
ill health in trees.
It has been developed
by Dr Bellet-Travers
of Trees-Project Ltd.
in the UK. Thermal
imaging has been used
by more than 50 clients
including Woburn Abbey,
The National Trust,
Blenheim Palace, The
National Trust for
Scotland and many
local authorities.
It is an important
tool that allows a
quick, non-invasive,
health appraisal of
the whole tree. The
method is not only
used to determine
the extent of decay
but also the amount
of healthy tissue
present that will
contribute to the
continued survival
of trees. Consequently
fewer trees require
maintenance work or
removal.
The
simplicity of the
technology allows
a large number of
trees to be surveyed
in a day. This combined
with the simultaneous
analysis of the whole
stem means that thermal
imaging can offer
considerable savings
over other technologies.
Thermal
imaging is the only
non-invasive technique
that can distinguish
between living and
damaged stem tissues.
Parts of the tree
that are healthy have
an even heat distribution
at the surface. When
wood is altered by
physical damage or
pathogens, cooler
and warmer areas develop
at the surface. These
reveal the presence
of both damaged and
healthy tissues.
We
have Professional
Indemnity Insurance.
We are Professional
