The first webinar of the 2026-27 season will be on Thursday 17th September at 4pm (BST). 

Qualification – Dimensioning: A high quality – low input strategy for continuous cover management

With Georg Josef Wilhelm

“Qualification–Dimensioning” (QD) strives for the best integration into the natural dynamics of woodland ecosystems. Both the observation and careful assessment of above-ground interactions between trees provide the framework for targeted management practices. As a comprehensive methodology, QD offers a reliable basis for the production of very high added value stems in a small number of trees with very large crowns. Although these stems prdouce a low proportion of the total volume from the overall stand, they make a very high contribution to the total added economic value whilst reducing management costs.  Additionally, woodlands and forests managed under QD have considerable scope to provide for high value ecosystem and biodiversity services without compromise to high value timber objectives.

QD can be applied to woodlands of any composition and structure. It enables the straightforward conversion of young, even-aged forests into uneven-aged, continuous cover woodlands. QD allows for a wide range of tree species to be included in the mixture.

Qualification: During the early period of their dynamic height growth, the spontaneous development of the trees is given free rein to select according to vitality. Intimate contact between the trees drives the processes of differentiation and structuring. The effects of these processes intensify and solidify with each subsequent vegetation period. QD does not intervene in this spontaneous process in any substantial way. In terms of management, it is only important to ensure that there will be sufficient options in terms of number, distribution and species diversity when the time comes to select the target-trees.

Dimensioning: Once the desired knot-free stem height has been reached, the target-trees for the production of added value are selected. The intended branch-free stem height for the target-trees in QD is around 25% of their final height. Throughout the dimensioning phase, the target-trees are favoured by repeated interventions to exclude the death of branches at their crown base an to make sure that their crown spread progresses unhindered.

Maturation: Once a target-tree has reached 75-80% of its final height, crown contact with other target-trees is harmless.

Regeneration and Establishment: Regeneration is a perpetual process that sets in when trees are in their advanced dimensioning phase. Any operations and investments, including planting if necessaray, are restricted to clumps measuring 5 to 7 metres in diameter, spaced 12 to 18 (24) metres apart. These clumps ensure sufficient recruitment of future target-trees.

Georg Josef Wilhelm was born in 1957 and completed his Forest Sciences studies at the University of Freiburg in 1981. Following careers as a forest planner, forest office manager and department head at the Central Office of the Forestry Administration of Rhineland-Palatinate, he served as a senior official in the Ministry of Climate Protection, Environment, Energy and Mobility of Rhineland-Palatinate from 2015. Until his retirement in June 2023, he was responsible for close-to-nature forest management, forest protection, forest planning, and forest research. From 2005 to 2019, he was a member of the Scientific Council of the French National Forestry Office (ONF).

He developed the close-to-nature forest management strategy Qualification-Dimensioning (QD), which has been playing an important role in Rhineland-Palatinate for more than 30 years now.

He has close ties to practical forestry through his honorary engagement, including 10 years as first deputy mayor, in the town of Blieskastel with its 1,900-hectare municipal forest. However, his most significant connection to continuous-cover management is his own private woodland in north-eastern France, which was awarded the Nature Impact Fund of WWF France in 2025.

All our members are warmly invited to attend our Extraordinary General meeting on 11th June 2026.

This will be a chance to consider the new constitution of Pro Silva Britain and we will be confirming the first board of trustees prior to submitting our application to register Pro Silva Britain as a Charitable Incorporated Organisation. 

This meeting will be online via Zoom – please book your tickets HERE.

You may pass on your apologies if you wish to administrator@ccfg.org.uk

Following the AGM in March, here is a letter from our Chair: 

Dear CCFG Members,

I’m writing to update you on some exciting developments at CCFG. Over thepast year we have been busy working on the organisation’s strategy, which has involved consultation with members, an appraisal of our partners andstakeholders, and the identification of three strategic objectives. The process has been rather long but extremely valuable for the committee as we are now working on the operational plan to deliver against these new objectives overthe next 10 years. A summary document presenting our strategy will be shared on our website very soon!

Two recommendations emerged from our strategy, firstly renaming and rebranding the organisation as Pro Silva Britain, this is to better align our mission, principles and communication with the 26 member countries in the Pro Silva family; and second to become a charitable incorporated organisation, which will enable us to apply for grant funding to run projects as we grow as an organisation. In forming the new charity, we would be very pleased to hear from any members who might be interested in becoming a trustee and helping to guide Pro Silva Britain in achieving its mission of promoting the benefits of Continuous Cover Forestry, for the environment, for society and the economy. We are particularly interested to hear from any members who would be willing to undertake the role of Treasurer, as our current Treasurer Solange Montero Terry will be standing down at our AGM in 2027. There are also opportunities to get involved in the work of our country branches in either England, Scotland or Wales, so please email me directly if you would be interested in getting involved in any of these roles, and to bepart of a very exciting time in the organisation’s evolution!

Please join us at the extraordinary general meeting on Thursday 11th June, and hoping to see you on a field visit very soon!

Best regards

Jonny Hulson

 

CCFG visit to Morton Hall

By invitation from Andrea Mason

THEME:

The Morton Hall Estate woodlands comprise some 86 ha located to the west of Retford in north Nottinghamshire. They originate from nineteenth and twentieth century plantations on marginal agricultural land.

Our main management objectives are:

1) To maintain and enhance the landscape values of the woodlands;

2) To increase the production of quality timber;

3) To increase biodiversity value and to conserve existing ecological features;

4) To increase woodland resilience against the impacts of climate change and other hazards;

5) To manage the woodlands to make a profit.

CCF type regimes were introduced into the management of old broadleaved stands at Morton over 40 years ago. We use a system of small gap plantings to introduce structural and species diversity. We have a wide range of species present in the stands and use the tree collection in the pinetum to help advise potential future plantings of alternative species. We also use ESC climate predictions to attempt to future-proof our plantings. Control of browsing animals since the 90’s has increased natural regeneration in many parts of the woodlands.

For more information please see this link to a Quarterly Journal of Forestry article.

CCFG visit to Fingle Woods, Devon

By invitation from the Woodland Trust

THEME:

An opportunity to discuss the early stages of the transformation to CCF as part of the woodland restoration project at Fingle Woods. We believe we have selected a number of stops to demonstrate how a well-managed conversion from a partially neglected conifer plantation to a more structurally varied woodland and ecologically diverse habitat can be achieved. We are at the initial stages of that conversion but it’s a good time to discuss the speed of that conversion and how the blend of economic and ecological factors are influencing that speed, as well as the impact that the topography and deer pressure have on its success.

For more information please download a map of the visit and Fingle Woods CCFG visit programme. 

Rendezvous time – 9.30 hrs, Thursday 23rd April 2026

Meeting point – Fingle Woods

Carpark facilities – We would like to share vehicles during the day to reduce vehicles. Please indicate during booking if you have a vehicle that is 4WD or with high ground clearance and you would be willing to drive it with others. Composting toilets are available at the meeting point.
