For the first time Barcham Trees will be bringing our Seminar Series to you in the comfort of your home or workplace!

This seminar will take a look at a topic which is very close to our hearts at Barcham and has wide ranging application across many facets of the tree industry.  Choosing the right tree for the right place is a responsibility which is so important to so many different professionals involved in planting trees and has a profound impact on the environment for many years to come.

For this presentation we offer to you two great speakers in Dr Andrew Hirons and Dr Henrik Sjöman, who will give you their respective thoughts and research regarding this wide ranging topic.

The event will be streamed live on Zoom on Wednesday 23rd June between 12noon and 2pm, be hosted by Keith Sacre and Ellen Thurman-Carvey and will offer a Q and A session in which we welcome delegates involvement.  For anyone who cannot make this session, we will make the recording available across platforms as soon as possible.

To register to attend, please click on the link to book and send us your details.  We will then contact you in due course with details of how to join the event on the day.

If you have any further questions, please do not hesitate in contacting Ellen – [email protected]

Jac Boutaud manages council-owned trees in Tours, a medium-sized city in western France, on the lower reaches of the Loire river.

Jac is the founder and a Trustee of “Les Arbusticulteurs” (which literally translates to “The Shrubculturits”) a charity promoting better use and management of shrubs from a technical, landscape, economic and environmental perspective.

He is also the founder and manager of the Petite Loiterie Arboretum (www.lapetiteloiterie.fr), a 12-ha “pedagogical park” designed for both professional and the wider public to learn and experiment with tree and shrub pruning and study their architecture. His ‘collection’ is unique in multiple ways:  It only includes specimens readily available in commercial nurseries (it boasts over 2,000 species and cultivars).

Trees and shrubs are grouped based on similarities in their foliage, so that people can compare and contrast and therefore recognize them.
Several individuals of many given specie of shrubs and some given specie of trees are planted, with one left to grow unpruned while the others are subject to different pruning techniques.  It includes over 2km of mixed species hedges, wetlands and meadows, maintained with environmentally friendly techniques.
Jac regularly delivers training and workshops for students, public and private sectors professionals and non-professionals on tree and shrub pruning and management.  He is the author of one of the reference text books in France on formative pruning, published in 2003 by the French Society of Arboriculture.

On Wednesday 18th March, he will be visiting Barcham Trees to speak about his work.  This seminar will be free of charge to attend, with lunch and refreshments included and places limited to 60 in total.

The day will run from 9.30am to 3.30pm at our site in Cambridgeshire, CB7 5XF.  Please click on the link to the right to book your space.  If you have any further questions, please call us on 01353 720 748 or email [email protected].

There will be a series of talks on trees in the landscape, past, present and future. Presented by a number of different expert speakers.

After the talks a tour around the great park will take place at approximately 3.30pm. This tour is optional.

Please note: Tea and coffee will be provided but we are unable to supply lunches, so please bring a packed lunch.

In the Netherlands treecare is professionalized in the past 20 to 25 years. Before this time arborists used a self-proclaimed title like ‘treesurgeon’. Since the first Visual Tree Asseccors, and the European Tree Workers were introduced and later the European Tree Technician, clients were able to demand these certifications
to improve quality of work.

Generally this was a boost to the industry as companies couldn’t get work anymore if they had no certified employees. As a result of this movement and still even some bad work, clients realised that there is a need for standards, procedures and protocols. Typically these standards are products by commercial companies
who have their effort in the licenses they sell to clients.

Also the schooling system was renewed by the new certificates and ideas about treecare and -consultancy. The result of these certificates is that the base-level of the industry and her employees had grown rapidly. Or is it now just more of the same, because of the certificates?

This seminar will be held by 3 leading specialist in the Dutch treecare industry. They all have a specialisation in this industry and a low threshold way to transfer benefits and opportunities to the audience.

The topics they will talk about:
Systematic process management
Contracting methods and standards
Municipality organizations and integral work
Appraisals
Management structure trees
Tree related certifications and education
Systematic pruning models
Actual municipality pest & diseases
Dutch research in arboriculture

As the experience of the speakers is wide spread they are enthusiast to be challenged by your questions to give a unique insight in the Dutch situation.

· Basic Principals & Common Mistakes

· Drainage considerations and options

· The use of geotextiles

· Urban Tree Soils – which one?

· The Topsoil Industry – is it really topsoil?

1. Evaluation of pest and disease management systems for ash die-back, oak processionary moth, acute oak decline and honey fungus.

2. Evaluation of soil decompaction techniques (air-spading, vogt, vertical mulching) to improve health and vitality of declining trees.

3. Influence of soil amendments on enhancing transplant survival of trees.

4. Correct planting techniques and weed control measures.

5. Techniques to measure tree health (chlorophyll fluorescence, electrolyte leakage, starch analysis) and their applicability for tree managers

We live in truly volatile and insecure times, defined by for example, enhanced climate and other environmental change, and major political and governance changes across the globe. Conditions are not always optimal for long-term and sustainable urban forestry. This presentation looks at how urban forestry in different cities and countries perform under increasing pressures. It draws lessons from situations where it faced major challenges, ranging from drastic cutting of government support in Ontario, Canada, to the increases in pests and diseases facing large parts of the urban forest. It also identifies cases where opportunities have emerged, such as the launching of China’s national Forest City program and the global trend of cities implementing so-called ‘nature-based solutions’. Specific focus will be on how the individual urban forester is impacted by this climate of change and how they are able to be successful.

When, during the Silurian Age, the colonization of the lands began, the water-plants had to accomplish new evolutionary strategies to satisfy essential requirements as the uptake of water and nutrients from the ground.
Such a complex adaptation was possible by the help of a mutual plant-fungus symbiosis located at the feeding root apexes.
In Ectomycorrhizae the fungal mycelium densely covers the root apex increasing the soil exploration in a kind of root system prolongation made of fungus. Furthermore, the fungal component exhibits an important antagonistic behavior towards other soil-borne fungi, protecting the root tips from many diseases caused by fungal parasites (i.e. Fusarium, Pythium, Phytophthora).
The workshop will focus on the biology and the behavior of such fascinating symbiosis, with in depths on the identification of mycorrhizae in root samples directly collected at the Barcham Nurseries.
