Seminar XI
Trees: The Key to Climate Proofing Our Cities
The Royal Geographical Society, Kensington, London
10th July 2008

Other important information on trees & climate:

Temperatures in UK cities are predicted to rise by 3–7°C by the end of the century. Research indicates that a 10% increase in urban tree cover would completely neutralise this impact. According to the Trees in Towns II study, trees are being lost at an alarming rate and urban deforestation is offering a hot future for city life.
With better co-ordination and within existing government guidance and management mechanisms it is possible to achieve the level of canopy cover that will make the difference. This requires a strategy that, wherever possible, all large trees are conserved and planning and design ensure that we grow trees successfully to become big trees with big canopies.
This pioneering conference brought together a wide range of speakers to explore practical possibilities to reverse tree loss within the current planning framework. Our aim is to drive an initiative to achieve the required canopy increase. This can be done but only through the widest possible involvement between all relevant stakeholders, professions, government organisations, citizens groups, etc.

Seminar IX
Integrated European Tree Assessment for Highway & Amenity Tree Inspection
Tree Statics & Fungal Decay
Non-invasive Tree Hazard Inspection & Risk Decision Making
Venue: Coombe Lodge, Blagdon
Nr Bristol BS40 7RG
15th & 16th November 2007
|
|
Individual tree inspections and highway tree surveying decision making can be a complex procedure. This seminar introduces European tree stability assessment methods to improve reliable assessment. The papers & practical guidance will introduce methods for interpreting decay patterns, including the steady state balance (between fungal decay and adaptive growth) for determining structural integrity in trees.
Experience shows that sound wall thickness can be far lower than is typically considered acceptable in the UK. This knowledge provides the basis for conservation arboriculture which is of particular value . The seminar explores fungal tree decay patterns, basic engineering concepts, the interplay between decay processes and the Static Integrated Assessment (SIA).

Venue: University of West of England, St Matthias Campus, Bristol
12th July 2007
|
|
Building on the success of last year’s introduction, this seminar explored arboricultural policy, case law and risk management to support professional
confidence in risk decision making.
Working with key thinkers in risk management from DARM (Middlesex University),
University College London and others, TEP seeks to build a strong framework to
inform the arboricultural industry.
TEP’s approach is that our industry cannot resolve defendable risk management
questions without significant contributions from both risk decision making and
legal specialists

A one-day TEP seminar, in partnership with the Arboricultural Association
- In 2006, TEP launched its Tree Morphology theme with an inspiring, in-depth two-day seminar.
Then in 2007 TEP provided a unique opportunity to experience two exceptional scientists in this field.
Their understanding and interpretation of patterns of tree growth has the capacity to profoundly influence our views and change and enrich arboricultural management practice.

Tree Morphology
Principles & application of tree morphology
for diagnostics & management
Venue: Ashton Court, Bristol
23rd & 24th March 2006
Read Seminar Review
|
|
This two-day seminar is an in-depth exploration of tree morphology intended to introduce and develop understanding in an arboricultural specialism mainly developed and used on the Continent. Tree morphology seeks to identify and apply architectural rules inherently coded in the tree.
One of the implications of this view is that the physiological and environmental history of the tree is somehow recorded in its form, if this could be properly ‘read’ and interpreted. While it is an increasingly sophisticated discipline in modern arboriculture, it builds on some of some very early arboricultural observations that can be found in Leonardo da Vinci’s notes on tree architecture and later in Wolfgang Goethe's observations of form and function in plants.
The
Speakers: |

Pierre Raimbault, Professeur, Institut
National de Recherches Agronomiques d'Angers, France
Use of tree architecture as a basis for tree assessment:
the principles and main applications:
Pierre Raimbault, one of the main proponents of tree morphology,
has presented a model which views the tree in terms of standard
morphological developmental stages, that if correctly observed,
may be used to diagnose perturbations in physiology. The model
is used to understand the ageing process, physiological stress
and as a diagnostic technique to determine tree management
options.
Dr
Milena Martenkov, Dep. Tree Eco Physiology, Mendels University,
Czech Republic
Interdisciplinary approaches to understanding branch & root architecture:
Dr Milena Martenkova contributes to experimental investigation in multi-disciplinary approaches. Her work focuses on branch architecture and root morphology through the investigation of branch and root architecture
Dr
David Lonsdale, UK
Tree morphology & implications for tree assessment & management:
Dr David Lonsdale will investigate how tree morphology has become internalised in tree assessment & inspection methodologies; how this draws on understandings of twig architecture and is used to recognise a tree’s “life stage” or condition of impaired vitality. He will examine decay as a morphological process in ancient trees and trends in arboriculture that focus on a morphological approach to recognition of bio-mechanical features to establish notions of ‘defects’ employing visual comparison with a perceived species ‘norm’. He will also explore how morphological factors may be taken into account when assessing tree condition, including intra-specific differences & effects of soils & climate.

This is a master class in the theory and practice of tree
statics. It is our intention that through better understanding
of the science and technology in this field, a more informed
debate will take place within arboricultural circles for the
benefit of good tree management practice. Delegates will have
the opportunity for hands-on experience of the techniques
and will be taken through the theoretical principles underlying
the methodology.

There is an inventive trend in arboriculture to provide the
practitioner with evidence-based information for diagnosis
and decision-making. This seminar explored relationships between
the tree and colonising micro-organisms, factors influencing
health & decline, and techniques available to predict
and remediate changes in condition.
With the increasing sophistication of techniques for the internal
mapping of decay in trunks, including recent developments
in the use of magnetic resonance and thermal imaging, it is
important to examine the strengths and limitations of the
devices concerned. This seminar explored these issues and
the necessity for improving tree failure data at a national
level, drawing from US experience.

Seminar I
Tree Statics and Dynamics
21 & 22 July 2003: The National Arboretum, Westonbirt
Tree Statics and Tree Dynamics A Two Day Seminar New approaches: an international perspective
on the assessment and management of tree risk. The National
Arboretum, Westornbirt, Gloucestershire. 21st and 22nd July,
2003.
The seminar was arranged to open discussion
and stimulate debate about practices that are currently used
in mainland Europe. Through such seminars Treework Environmental
Practice seeks to contribute to an improved professional understanding
of the issues relating to tree stability and risk management.
It is hoped that arboriculture in the UK will continue to
be open-minded in its exploration of scientific developments
and new techniques to inform an optimum approach to managing
trees for safety, amenity and biodiversity. Neville Fay.
