Best Practice Event - Thinning of Conifers

Thursday 21 October, Tullamore, Co Offaly

Registrations have now closed.

The Teagasc Forestry Development Department in association with the Forestry Division, DAFM invites forest owners to an important outdoor event focusing on the thinning management of semi-mature older conifer forests to improve timber quality while maximising future financial returns.


Many Norway spruce and Sitka spruce forests are approaching second or third thinning stage with the potential to produce increasing volumes of valuable commercial timber. This event will focus on how research guides the best thinning practice of Sitka spruce and Norway spruce. This approach also promotes timber quality, protects crop stability and grows future financial returns.

  • Practical tree marking exercises 

Practical tree marking exercise

The practical tree marking exercise consists of an interactive session on best practice in thinning Sitka and Norway spruce crops. 

The session will include an interactive learning session where participants will learn about thinning systems, types of trees to remove and volume to be removed in thinning using an interactive demonstration.

The session will be led by Dr Niall Farrelly who will discuss the results of thinning research and guide participants through the process of thinning for the production of high quality sawlog.
