BS 5837 Revision and New TPO Regulations

Course programme: 09.30 – 16.45

Morning session: BS 5837:2012

Trees in relation to design, demolition and construction – Recommendations

Presented by Richard Nicholson

‘BS 5837:2005 Recommendations for trees in relation to construction’ has been completely revised and republished in 2012. The revision took account of the testing of the 2005 version in various forums, changes in building practices, improved knowledge of the performance of materials and an understanding of those areas of the 2005 BS process that continued to benefit trees.

This AA half-day workshop will identify the main processes, look at the principle changes to the document, the decisions behind those changes and provide guidance to users of the document on how the standard should be implemented. There will be opportunities for discussion and questions facilitated by Richard Nicholson who chaired the review group and the editing panel.

Afternoon session: New TPO Regs:

The Town and Country Planning (Tree Preservation) (England) Regulations 2012

Presented by Peter Annett

Local Authorities have been using TPOs to protect trees and woodlands since the modern planning system was set up in 1947. The 1999 Regulations have been subject to different rules, introduced at various points over the years, which have complicated their implementation. The new Regulations, enacted on 6th April 2012, aim to simplify, streamline and improve the system and enable Local Authorities, tree owners, consultants and contractors to operate within a consistent, fair and user-friendly system.

This AA half-day workshop will describe the background and explain the changes that have been introduced, including details of the new, shorter and simpler model TPO and the associated procedures. There will be opportunities for questions and discussion with Peter Annett who, until recently, was the key person within DCLG responsible for these developments.

Mark Johnston, Chair, Conference Steering Group

Future ForestryICF has confirmed that it is now taking bookings for Future Forestry – Meeting the needs of the 21st century, it’s National Conference for 2012 on 16-17 May.

After a year in which we’ve seen the industry's reaction to policy decisions, huge public concern over forest sell-offs, biosecurity challenges, changing planting demands, tough financial decisions, increased bureaucratic legislation, and a potential long-term skills shortage on the horizon, the conference will look at where we go from here.

Future Forestry will look at forestry on the world stage, the challenges we’re facing in the UK, the complex relationship between trees and society, the opportunities ahead, and how we balance the diverse needs of stakeholders.

Conference chairman Marcus Sangster said: “If you predicted the changes then come and tell us. If not then come and hear what some of the industry’s leading experts – from home and abroad - have to say.

“We want industry professionals to join us to discuss how we can interpret society’s demands on our trees and woodland into innovative ideas for today's businesses.”

The conference will be held at the CBI Conference Centre, Centre Point, London, and ICF is offering early bird ticket savings for a limited period.

Speakers will include: The Rt Rev James Jones, the Bishop of Liverpool and Chair of the Independent Panel on Forestry; John L Innes, Dean of the Faculty of Forestry at the University of British Columbia; Tim Rollinson FICFor, Director General of the Forestry Commission GB; Dr Jason Beedell, Partner, Smiths Gore; Jon Owen Jones, Forestry Commissioner Wales and former MP; Charles Mynors (Conference Dinner), Barrister and leading tree law specialist.
