Executive summary
What the report is about
This project developed guidelines
for survey and inventory of private native forest resources, to encourage
adoption of proven, consistent and reliable methods. The project also summarised
features of some recent private native forestry inventory projects. This
report aims to increase understanding of the need for more consistent data
collection methodologies.
Who is the report targeted
at?
The guidelines are for use
by organisations that undertake regional inventories or assessments of
private native forests. Regional inventories or assessments of private
native forests may potentially be undertaken by, or for organisations such
as: Private Forestry Development Committees, Catchment Management Authorities,
State Government departments and agencies, and Australian Government departments
and agencies.
This report may also assist
people who are involved in mapping and inventory of native forests and
woodlands, in particular private native forests –foresters, regional natural
resource management groups and staff of government departments. In the
long term, more consistent data collection will allow greater data sharing
and more powerful planning and resource management across jurisdictions.
Background
Privately owned native forests
represent the largest category of native forests in Australia. Information
on the extent, composition, management and condition of these forests is
important to assist planning and management at local, regional and national
levels. Adoption of more consistent methods between organisations that
undertake regional mapping and inventory of private native forests will
lead to better data for assessment of area of private native forest, regional
wood supply, conservation issues, and reporting on sustainability criteria
and other benefits.
Aims/Objectives
The purpose of the project
was to develop guidelines for survey and inventory methods for private
native forest resources – to encourage and enable adoption of proven, consistent
and reliable methods within and between organisations.
Methods used
A workshop to develop guidelines
for regional private native forest resources inventories was held on 10
and 11 March 2005. These guidelines were prepared as a result of the workshop.
The guidelines include:
-
principles, general procedures
and minimum standards
-
the outputs required, for example,
maps and reports showing forest location, age classes or stand structure,
harvestable and restricted sites, timber and non-timber values, roads and
other infrastructure.
Results/Key findings
The guidelines clearly differentiate
two approaches to the collection of such data. The top-down approach aims
to collect generalised information over large areas. An alternative is
a bottom-up approach where data are collected at the individual landholder
level and amalgamated to a regional and national level. Regardless of the
method used, there is a need for standardisation of a wide range of aspects
of data collection for inventory and stand condition assessment.
The workshop provided the
opportunity to share information on approaches but detailed coverage of
the requirements was not possible.
Implications for relevant
stakeholders
Organisations that play a
role in coordinating regional inventory projects will improve data compatibility
in the future if they encourage use of these guidelines by others during
design and collection of inventory data.
Recommendations
The following 15 recommendations
aim to progress development of a standard approach.
-
Review existing vegetation grouping
approaches and develop and/or adopt a set of vegetation groups that can
be used at a range of levels (regional, State, national).
-
Where forest type descriptions
(such as the Broad Vegetation Groups used in Queensland) are used, that
these be allotted appropriate categories within the standardised set of
vegetation groups defined in Recommendation 1 above.
-
Develop a set of standardised
terms to describe forest management practices currently applied such that
data can be amalgamated from a local to a regional to a national level.
-
Where terms have previously
been used to describe management practices, that these be interpreted and
fitted to the terms adopted in Recommendation 3 as appropriate.
-
A standard set of classifications
be developed and adopted for all elements of mapping themes across GIS
systems. The GEODATA Topographic 250 000 series provides a strong base
and could be used as a model.
-
Where data are obtained from
organisations that have different approaches to classification that
a set of ‘conversion equivalents’ be developed to allow these data to be
used but to also allow the data to be amalgamated at the regional or national
level.
-
Where GPS units are used to
collect data, a standard approach to collection of raw data needs to be
prepared as this will greatly assist in providing a uniform approach that
will allow subsequent data aggregation.
-
Locational software packages
provide a simple and low-cost tool for navigation by combining the information
available on a topographical map and the locational detail from a GPS.
It is recommended that a simple document (compact disc based) be prepared
demonstrating the availability and use of locational software and the use
in private forest inventory.
-
Develop a set of standardised
descriptions to allow freehold land to be grouped into units where legal
status or management intent is likely to be similar.
-
Given the wide range of uses
for aerial photography, it is recommended that the preferred scale for
large-scale photography for forest inventory be agreed.
-
Prepare a technical guide outlining
the range of satellite imagery available, access, cost and derived products
that could be of assistance (such as SLATS, NPP); specifying standards
seems inappropriate given the rapidly changing nature of the tools being
developed in this field.
-
All reports generated as a result
of an integrated approach to private native forest assessment should specify
the log specifications applied in that region, including species, size
(length and diameter), straightness and internal defect.
-
Develop a set of standards for
GIS systems that will ultimately be used to generate maps; these standards
extend from standard data file names, standard mandatory field names and
formats through to standardised templates for map production.
-
Develop a set of protocols such
that data to be submitted to a national database on private native forests
conform to a set of agreed standards. These data should be available to
the general public for interrogation. The platform used by the Australian
Greenhouse Office National Carbon Accounting Toolbox may be suitable for
this purpose.
-
Develop a standard report ‘template’,
together with appropriate notes, to provide some level of consistency in
reporting.
