BACKGROUND
Past forest research activity has resulted in an extensive network of experimental trials on many aspects of silviculture and forest management. These trials have provided scientific data to assist in developing best forest practice and have also acted as demonstration areas for communicating research results. The NATFOREX project aims to create a national database of trials established before November 2007. It will give a useful inventory of intact and closed trials with the associated data, and silvicultural and management treatments tested. It will also facilitate reviews of knowledge gained to date and help to show areas where new trials may be required. In addition, important extant trials will serve as demonstrations of good forestry practice.

OBJECTIVES
To identify, maintain and manage a national network of field trials for the study of silvicultural and forest management treatments. Specifically to:

  •     evaluate the relevance of existing trials in the Coillte experimental plot network and in the research sections of other organisations;
  •     decide on the reliability of existing data and on the benefits of further data collection;
  •     carry out necessary maintenance on field trials earmarked for retention;
  •     collect new data in retained trials where required;
  •     integrate the findings and data from the trials into a public online database;
  •     identify information gaps;
  •     decide on the need to establish new trials.

    PROGRESS
    To date, more than 300 field trials and experiments have been visited. A total of 158 field reports have been reviewed, summarised and entered into in a database. Where there were originally about 1,500 experiments listed on Coillte's network, this number has now been reduced to about 980 and this figure is expected to reduce significantly as more inspections are undertaken and reports are made available. Work has begun on the transfer of non-metric data, collected prior to 1971, onto Excel for metrication and storage. Data presentation has been designed to be similar to that of other databases including the NoLTFoX database.
    Essential maintenance and assessment work continues on a range of experiments. In the past year 55 trials received attention, ranging from growth measurement to thinning to pruning, to scrub clearance, to final crop selection. Data from some of these trials were analysed to get a clearer view on their current status.
    Trial sites from Donegal to Cork and Galway to Wicklow have been inspected in the field. A common factor has been the poor quality of the maintenance of the experiments on the ground. This has had an impact on the ability of these trials to perform to their full potential. .
     
    ACTIVITIES PLANNED
  •     Decision on the retention of intact trials based on the field managers' reports, the quality of the existing data and the statistical soundness of the experimental design.
  •     Continued digitising of data from experiments that are closed.
  •     The database for the website (www.natforex.com) will be completed.
  •     The project management group will make a second field visit, this time to the midlands and West.
  •     Reporting on field trials will be completed.
  •     A distinction between trials which are valuable for their data output only, and those still intact and capable of producing valuable data will be made.
  •     Criteria for the retention of intact experiments will be drawn up.
  •     Criteria for the inclusion of the data from closed trials will be drawn up.
  •     The selection process for retained trials will begin.
  •     Work on selected trials including the compilation of Management Plans will begin.
  •     Further efforts will be made to include non-Coillte experiments in the work.
  •     The project group will work with a recently appointed statistician on the authenticity of experimental design and the reliability of experimental data.

    BACKGROUND
    Years of forestry research have resulted in an extensive network of experimental trials on many aspects of silviculture and forest management. These trials have provided scientific data to assist in developing best forest practice and have also acted as demonstration areas for communicating research results. The NATFOREX project aims to create a national database of trials established to date. The project will give a useful inventory of the resources available and silvicultural and management treatments tested. It will also facilitate reviews of knowledge gained to date and help to show areas where new trials may be required.

    OBJECTIVES
    To maintain and manage a national network of field trials for the study of silvicultural and forest management treatments. Specifically to:

  •     evaluate the relevance of existing trials in the Coillte experimental plot network and in the research sections of other organisations;
  •     decide on the feasibility of analysing existing data and on the benefits of further data collection;
  •     decide on the need to establish new trials;
  •     carry out necessary maintenance on field trials;
  •     collect new data in trials where required;
  •     integrate the findings and data from the trials into a public online database.

    PROGRESS
    In the last year the focus has been on developing methods on how the project data are collected. A list of 1,500 field trials established by state forestry and other organisations has been compiled. This list is the basis for all investigations in the project. A secure intranet site has been set up to store metadata about the field experiments. A project management group has been established to advise on the retention of field trials and inclusion in the database. An advisory group met during the year and contributed to the longer-term direction of the project.
    Part of the intranet development includes an early warning system that will alert the project to potential loss of trial sites. A number of sites were found to be part of the forest stands offered for sale as thinnings or clearfell areas under Coillte's marketing system. This risk was highlighted in the database communicated to Coillte's Forest Information System. A number of site visits were carried out to establish a practical reporting system to be used in deciding the status of experiments. One site was visited by the project management group so that they could appreciate the difficulties encountered by the project team in assessing a site. To date, in excess of 100 trials have been reviewed and reports on these are being compiled. Up to 500 trials have been documented in the NATFOREX database.
    A new tablet computer is used to report on field trials by creating high resolution digital maps. This work has been supported by Coillte IT. The company provided shape files: these are geospatial vector data, consisting of different layers of information about a field site, such as forest roads, forest compartments and experiment plot layers. Data recovery was completed during the year. Old computers and storage media have been checked for data, many were damaged and about a third of the corrupt disks were recovered.

    ACTIVITIES PLANNED
    The design of the NATFOREX internet site including an online database will be completed and populated with experiment records. A number of trials will be approved by the project management group for retention and the associated raw data will be entered into the database. Other (non-Coillte) stakeholders will be invited to contribute to the project. A statistician will be appointed to provide advice on the design of trials and quality of available data. Field reports on remaining intact Coillte trials will continue to be submitted to the project management group and an outline of research areas where retention of trials is recommended will be drawn up.
