Tree Life Training in Hong Kong
In 2010 Tree Life were approached by Luciana Wong of LNS (Learning
Never Stops) with regards to bringing our courses to candidates in Hong
Kong. In September 2010 we therefore went across to join LNS to deliver
four days of training in relation to Tree Inspection and British
Standard 5837. This training went exceptionally well and we are now
looking at other courses that candidates are asking us to provide. Most
of these courses are likely to take place in 2011 with just a few more
days of Tree Life training in December 2010 to look forward to.
The tutor delivering the courses so far has been Dave Dowson who is the founder and senior consultant of Tree Life Arboricultural Consultancy LTD.
A message from Dave...
to all of you that I met during my recent visit to Hong Kong, it was a
pleasure to meet you all, and Tree Life feels honoured and privileged to
have been invited to deliver training provision by way of BS 5837 Trees
in Relation to Construction and an Introduction to Professional Tree
arrived home safely after a delay sitting in the aircraft while
lightening and thunder prevailed over the airfield in HK. I met some
lovely trees and one or two scary ones that had holes in them that
probably would not have survived a UK chainsaw! The problems you face
with trees are not dissimilar to the ones faced here in the UK.
I did notice that the species are a little different and of course that
wall trees are a source of fascination for me and my camera.
was lucky enough to go and see the oldest tree in HK with its many
props, wires and ropes installed and also to see one of the trees that
remain after the ground under it was removed leaving the tree high in
the sky – always, it is interesting to see what other nations do for

the Major oak situated in Sherwood Forest the home of the legend Robin
Hood. Note the props and braces!
anticipate being back in HK during December to deliver a full 3 days
training for Professional Tree Inspectors covering risk assessment that
leads to a certificate of competence that is backed by the British
Government. This competence award has been out for consultation with all
British arboriculturists having had the opportunity to comment on its
contents. Therefore, it is understood to be best practice. It is
administered by LANTRA Awards which has responsibility for setting the
arboricultural standards for the country. Tree Life has taught this
course since its conception 3 years ago and to-date has run 26 courses
both here and in Europe.
course is an integrated assessment programme containing 3 tests of an
individual’s competence. A knowledge based exam covers the underpinning
knowledge of trees, pathogens, law and inspectors responsibilities, an
identification of fungi covers the candidates ability to determine the
type of decay caused by a fungal pathogen and finally a tree inspection
of 2 trees test the candidates ability out in the filed to determine
tree condition and then to specify the appropriate management
aim of the programme and the testing procedure is to provide the
candidate with specific tree inspection training and a certificate of
competence, industry and government endorsed that states that they are
competent to inspect trees. This may also provide proof to a judge that
they have had adequate training in the subject of tree inspection should
things go wrong following an inspection.
during the week I expect to deliver a session on the principles of
decay detection which will include Visual Inspection of the tree to
determine the point of greatest weakness and the principles of operation
of commonly available decay detection and/or measuring equipment and
the interpretation of results. This type of equipment has become a
valuable addition to the tree manager’s armoury in assisting with
decision making using more scientific approaches. Not one item of
equipment can give the answer, but when used with arboricultural
knowledge and experience can greatly aid the decision making process.
The use of this equipment has become almost essential when electing to
keep trees with defects as a more detailed and quantifiable risk
assessment is required as proof of a manager being reasonable.
that can be covered includes non-invasive techniques, acoustic
equipment, drills and the fractometer. A follow up field day will be
organised in the future so that the equipment can be seen at work in a

LANTRA Professional Tree Inspection 3 Day Course
The format of this course is as follows: The
three-day course aims to provide specific tree inspection programme at
an advanced level for competent arboriculturists to enable them to reach
a level of competence that can be recognised as having received adequate training.
are required to inspect trees and specify the necessary remedial works
and record the inspection process. This would then form part of a
defensible system. The course is not aimed at covering report writing
however, presentation of findings will be examined and advice given.
is also an opportunity for candidates to update their level of
knowledge and its application to inspecting trees particularly if that
previous knowledge was gained sometime ago.

contractors etc. Also as a preliminary course for contractors,
dedicated tree inspectors, assistant and principal Arboricultural
officers wishing to complete an advanced programme.Objectives:
Identify obvious defects by visual inspection of the trees from ground level with the aid of binoculars, mallet and a probe.
To record defects found and place the tree in a broad category of risk rating.

Tree Decay Fungi Knowledge & Recognition
course would cover the work of Dr F Schwarze, Prof. Dr Claus Mattheck,
Dr Alan Raynor, Dr Lyn Boddy, Prof. Dr Olaf Schmidt. All the content
would be specific to Hong Kong fungi.
To understand how decay fungi found in Hong Kong cause wood degradation in living trees
To understand the different strategies employed by the decay fungi to colonise woody tissues and the implications for tree care
have knowledge of the different types of rot caused by the decay fungi
and be able to recognise white, brown and soft rots and the implications
for the tree
To recognise the principal decay fungi found in living trees in Hong Kong
know for each fungi - a typical host tree species, colonisation
strategy, type of rot they cause, part of tree attacked and the
significance for the tree.
To have knowledge of the wood-decay
processes and host fungi interactions as this is essential to providing
objectivity in risk assessment involving fungi and trees
