Mid-conference field trip

14 November, 2012
Uneven-aged Nothofagus forest management and conversion of Pinus radiata plantations to uneven-aged Pinus/Pseudotsuga/Nothofagus forest on a family owned farm/forest in the Canterbury foothills

Post-conference tour

17-23 November, 2012
The seven day post-conference tour took place 17-23 November 2012. It started in Lincoln (site of conference sessions), traveled to the north-western part of the South Island over Lewis Pass, then down the West Coast of the South Island to Hokitika and Franz Joseph Glacier, and then return eastward over Arthur's Pass to Lincoln.
Much of the area to be visited is scenic with mountainous terrain, wide alluvial flood plains, and relatively intact indigenous forests. The tour visited red (Nothofagus fusca)-silver beech (Nothofagus menziesii) forest and hard beech (Nothofagus truncata) forest in the north-western South Island where we discussed the natural dynamics of these forests, the application of small group-selection harvest systems, and a beech timber processing plant (NZ Sustainable Forest Products Ltd). The group then visited terrace rimu (Dacrydium cupressinum, Podocarpaceae) forest in the central part of the West Coast and discussed forest dynamics and the historical application of single-tree selection harvest systems. The group travelled far enough south on the West Coast to visit Franz Josef Glacier and the well-known associated chronosequence leading to dramatic changes in soils and forest vegetation. In the return trip over Arthur's Pass we visited montane rata (Metrosideros umbellata)-kamahi (Weinmannia racemosa) forest on the wet western side of the mountains and mountain beech (Nothofagus solandri var cliffortioides) forest on the drier eastern side.  

Scope and objectives

Over the last few decades there has been increasing interest in Uneven-aged forest management (UAFM) and it has become increasingly important. The main reasons for this include the increased significance of nature conservation, ecosystem services, forest stability, recreational functions and difficult economic conditions. In spite of many successful practices of UAFM, its ability to integrate ecological theory and natural processes with forest stability, climate change adaptation, technological feasibility and economic efficiency are under debate. This conference is an opportunity to debate and address these issues.

The conference objectives were to:

  1. Investigate ways of optimising timber production through UAFM
  2. Compare long term best practices of UAFM across different forest types
  3. Clarify understanding of UAFM and its linkages with other silvicultural systems
  4. Discuss future applications of UAFM in the context of ecosystem services and resilience to climate change.

Conference structure

The conference will included  three days of sessions and a one day in-conference tour to managed uneven-aged Nothofagus forests in the nearby Canterbury foothills. Each day opened with a plenary session and continued with working and poster sessions. The seven-day post-conference tour visited natural and managed forests on the western South Island, New Zealand (temperate conifer-broadleaved hardwood and Nothofagus forests).

Target audience

 The conference bridged scientific, professional and non-forestry views on uneven-aged silviculture. Forest managers, owners, practitioners, teachers, scientists, conservationists and everyone interested in the broad spectrum of the uneven-aged silvicultural management were warmly welcomed.

Themes for symposia may included:

  • Ecological studies and old-growth forests as a reference for UAFM
  • Theoretical background, quantitative indicators, management planning
  • Modelling of UAFM (on scales ranging from individual trees to landscapes)
  • Case studies of UAFM best practices
  • UAFM in forests with emphasis on non-timber goods and services (e.g. biodiversity conservation, protection forests, etc)
  • Linkage of UAFM to other silvicultural systems
  • UAFM beyond the northern temperate and boreal forests: Mediterranean, tropical, and southern hemisphere countries
  • Even- to uneven-aged conversion
  • Restorative thinning to promote old-growth characteristics
  • Alternative silvicultural management in the European Nordic Countries
  • Provision of ecosystem services from both public and private lands
  • Application UFAM on Maori/indigenous peoples lands
