    CAS Member Announcment

    By Mark Chester, 13 September 2017

    Apologies for the delay in sending this. The CAS laptop broke on Monday, and normal service is only now being restored.

     

    Since Monday, the team at CAS Towers has been based at the Arboricultural Association Amenity Arboriculture Conference (stand A8).  We have shared the stand with representatives from the Country Landowners and Business Association (CLA) and we look forward to working with them in coming months to promote best practice and enable CAS members to access the member resources available.

     

    Ian Barnes, who is a member of the CAS Board of Directors, and an AA Registered Consultant, will be available at the conference today to answer any questions you may have on consultancy.  He is also demonstrating the range of non-invasive decay detection tools available from Tree Diagnostics.  They are on stand C6.

     

    We are launching the new Lantra Mortgage course.  The first date for the new course will be Tuesday 30th January, at Lantra House, Stoneleigh Park in Warwickshire.  Places will be limited at this launch event.  If you wish to book your place, then contact me at mark@consultingarboristsociety.com .  This is a one-day course, successful completion of which will lead to the awarding of a CAS Competency and being listed on the database of those who can provide a Mortgage report.  Cost is £250 + VAT.  However, for those who have previously completed training either with Dr. Dealga O’Callaghan or Dr. Jon Heuch, a 50% discount is available (£125 + VAT).

     

    You will be able to download the new CAS app at the conference.  Development of the app has been generously supported by CAS member Ian Barnes and his team at Tree Diagnostics.  They will also be at the conference, demonstrating their range of decay assessing equipment.  Ian is a member of the CAS board, and his stand C6 is near to the refreshment table, ideal if you have any questions for him whilst having a drink!

     

    Don’t forget that the CAS at Bartletts Day is fast approaching.  This will be a great occasion when we can see the facilities at their Reading base and hear from the team about their current research work.

     

    Finally, as it is the second week of the month, we have a look through the archives at the Ancient Tree Forum to consider their Tree of the Month.  This month, we look at the Bulborrow Yew..

    RIBA are presently preparing their 2018 directory.  CAS has run a feature in previous years funded by members listed within it, who benefit from a significant discount.  If you wish to consider this, please do let me know at mark@consultingarboristsociety.com

    CAS member announcement

    By Mark Chester, 08 September 2017

    On Monday, the team at CAS Towers will be based at the Arboricultural Association Amenity Arboriculture Conference (stand C8).

     

    We will be launching the new Lantra Mortgage course.  The first date for the new course will be Tuesday 30th January, at Lantra House.  Places will be limited at this launch event.  If you wish to book your place ahead of the official launch, then contact me at mark@consultingarboristsociety.com .  This is a one-day course, successful completion of which will lead to the awarding of a CAS Competency and being listed on the database of those who can provide a Mortgage report.  Cost is £250 + VAT.  However, for those who have previously completed training either with Dr. Dealga O’Callaghan or Dr. Jon Heuch, a 50% discount is available (£125 + VAT).

     

    You will be able to download the new CAS app at the conference.  Development of the app has been generously supported by CAS member Ian Barnes and his team at Tree Diagnostics.  They will also be at the conference, demonstrating their range of decay assessing equipment.  Ian is a member of the CAS board, and his stand C6 is near to CAS, ideal if you have any questions for him!

     

    Representatives from the CLA will also be in attendance on all three days, to explain how membership of that organisation could benefit your operation.  We will be sharing the benefits available via CAS next week.

     

    We will have a limited number of signed copies of ‘Veteran and Other Ancient Trees – Guidance on Management’, edited by Dr. David Lonsdale.  These are available on a first come first served basis.  They cost £25 each (RRP £30).

     

    Finally, we will have a limited number of hard copies of the new CAS brochure.  This guides the reader through the CAS journey and explains how the various courses fit together.

     

    This is one in a series of case studies exploring the evaluation process for assessing the condition of trees where decay is a major factor to be considered in the management approach.  Much of my work focuses on managing the tree collection at RBG Kew.  However, sometimes I am asked to provide guidance for trees elsewhere.  In November 2016, I was asked to guide on the management of several Horse Chestnut trees for my associate Mark Chester of Cedarwood Tree Care.

    Kew Gardens includes a collection of Horse Chestnuts planted in the 1920s to commemorate various battles of the First World War.  The trees were not the best of specimens when planted, and in recent years have required careful management.  They are among the many trees at Kew for which felling is a very last option.

    The trees I was asked to assess are important to the property owner.  The trees needed management, having large, spreading crowns and evidence of decay.  Careful management was needed to ensure retention for as long as possible.

    The inspection was a detailed inspection (level 3 inspection)

     To carry out this inspection I used a PD400 micro drill to assess the decay. Measurements from this assessment can be found at the end of this article.

     

    On the day of my site visit the weather conditions were bright and clear. Given the general weather for that month, this was a relief, especially as I supervised the pruning works.

    In part one, I shared my assessment of the first tree.  I shall now share how I assessed the second tree.

    The main concern for this tree was the failure of part of a major branch within the crown.  There was appreciation that the tree needed pruning.  The priority was to ensure this was as minimal as could be sustained.  Cavities at the base were a cause for concern.  Did they indicate more extensive decay?  In contrast to the Horse Chestnut of the first case study, this tree was in good vigour.  From the measurements taken (see the end of the article), there is very little evidence of decay colonisations. Figures 8- and 9 show some dysfunctional tissue which is the early stages of decay.  In the absence of any fruiting bodies, it was not possible to establish the cause of the decay. Although dysfunctional tissue is present, the area is only small.  This decay therefore would not affect the overall structural strength.

    I recommending that it would be beneficial to undertake a further level three assessment including a decay detection in 2019, three years on from this assessment. I was particularly pleased as the use of the decay assessment enabling targeted pruning to be undertaken in a very sensitive manner.

  • Working Together

    By Mark Chester, 05 September 2017

    As we count down to the Arboricultural Association’s annual Amenity conference, starting on Sunday in Exeter, it seems an apt moment to reflect on the various collaborations that CAS is involved with, and to thank industry colleagues for their spirit of co-operation.  A reminder that CAS will be at stand C8.  Please do come and say hello, and collect our limited edition new brochure in hard copy, and down load the new CAS App.  There will also be a demonstration by PINE Technology and representatives from the CLA on hand on all three days to explain how the CLA can support CAS members.

     

    CAS has always been welcomed to the annual AA conference.  However, until recently, the idea of working together for the good of the industry remained an aspiration for us.  I am delighted to say that under the leadership of Stewart Wandrop and chairman Keith Sacre, the AA has embraced the hand of friendship and we are exploring ways to work together.

     

    The Institute of Chartered Foresters is the flag bearer for arboriculture, holding the Chartership.  This is the gold standard for any professional.  I was delighted to become Chartered in 2015.  I am delighted to announce that our two organisations will be promoting each other’s events in coming months.  The ICF will start by promoting the upcoming Tree Preservation Orders course, Amenity Tree Valuation and Young Trees this autumn.  And here at CAS Towers, we will be pre-viewing the upcoming Tree Officer conference at Telford in November.  Not just for tree officers, it will explore the issues of particular interest to our public sector tree managers, and CAS members are invited.

     

    We of course continue to work with Tree Charter, Perennial, BALI and Fund 4 Trees.  Updates for all are below.

     

    As it is the first week of a new month, we continue with our regular feature of the Business Blog.  In August, we explored the lessons in success from observing the managerial style of Sir Alex Ferguson.  This month, we look at the remarkable achievements of Claudio Ranieri with Leicester City, and explore the lessons that can be learnt from his title winning season…
