Provenance

Background

The different tree species found in Irish forests have natural ranges which cover a variety of habitats and climatic zones.  In their natural environment, these tree species have adapted to their local conditions and possess different characteristics depending on their location. Each tree in a partuclar location has inherited characteristics that allows it to survive and grow in those conditions. When grown in Irelnad, the performance of the trees from these different sources can be very different. To determine the best sources, seed origin or provenance studies, have been carried out by the Forest Service since the early 1960s. These have subsequently been continued by Coillte and Teagasc with funding from Coford. Now, the FORGEN Programme continues some of that work with the focus on oak, Sitka spruce, ash, beech, 

Provenance Trials of Broadleaf Tree Species 

The provenance trials on the broadleaf tree species are a group of trials comprising studies on oak, beech, ash:

  1. Native oak provenance trials planted in 1988, established from 29 Irish oak sources are located at sites in four Coillte forests:  Camolin, Durrow, Belturbet and Donadea.  More ... 
  2. Native oak provenance/progeny trials, planted in 2006, established from xx Irish oak sources, located at three privately-owned (non-Coillte) sites: Tullynally Estate, Co. Westmeath, Manch Estate, Co. Cork and Shillelagh, Co. Wicklow, more ... 
  3. Comprising ash, beech and oak from Irish and overseas seed sources, planted in 2008/09, the trials are located at Camolin Park, Co. Wexford (Coillte site) and at Manch, Co. Cork (Private INFF managed).  The purpose of these trials is to assess the best Irish seed sources available to date and to compare these with established overseas origins in order to source future seed supply and direct future seed stand management.
