The most urgent need for them (surveys) is to supply information
needed as a basis for efficient work in the creation of forest
reserves, the construction of permanent improvements (roads) and
the distribution of the field force. While satisfying these needs, these
forest surveys will yield at the same time detailed information
regarding the stand of commercial timber in the different regions, its
size and quality, and its availability for successful lumbering
operations, which will be of great practical value to lumbermen and
other forest users, as well as in the development of a progressive
public timber sale policy.’

Overview and Introduction for the Uninitiated
British Columbia’s forest inventory program began as a general examination of
the province and a search for the highest quality and most easily accessible
timber. Over the course of nearly eight decades, forest inventory methods
have become much more sophisticated and are currently designed to answer
many questions that were not even formulated until the 1990s
John Parminter, Research Branch, B.C. Forest Service

The Basic Recommendations of the Peel Royal
Commission
 A total re-design of the Inventory and
Management systems
 A commitment to complete inventories
of all renewable forest resource values
using standardized compatible systems.
Vegetation Resources Inventory Design Principles
1. The inventory covers the entire B.C. land base.
2. The inventory based on estimates of polygons.
3. Standardized inventory methods based on a
standardized database
4. The inventory can be externally audited.
5. The inventory will accommodate recompilation for a
variety of purposes.
Vegetation Resources Inventory Methods
• Photo Interpretation – The subjective
delineation of polygons and estimation of
attributes.
• Ground Sampling – Plots randomly
selected, and detailed measurement are
made of resources at one or more locations
in each selected polygon.
• Statistical Adjustment – A statistical
analysis of the data and the reporting
function.
Vegetation Cover Update
Update Process
• Capture of new attributes
• Capture of new linework
• Project data
Update - Definition
• “Harvested Stands” (Harvested through to
Free-To-Grow)
• “Managed Stands” (post free growing).
• “Natural” Stands; when things change (i.e.,
fire, disease, insects, and succession).

Until recently, upon the continent of America, men gave little
thought to the extent of the forests and were contented with the
vague idea that, like the water that ran to waste in every stream,
the timber supply was inexhaustible.”

How are the openings located across the neatline
(and/or several mapsheets) addressed?
In RESULTS an opening is identified to 1 mapsheet only
(no change from ISIS)
In SDE there are no map boundaries:
What is the relationship between FTA and RESULTS?
Do they link by mapsheet opening number?
Linked by Licence number, CP and CA:
One RESULTS polygon =1 Licence number/CP/CA
1 Licence Number/CP/CA=many RESULTS Polygons

VDYP
The Variable Density Yield Prediction (VDYP) is an empirical yield
prediction system for natural stands, based upon temporary inventory
sample and permanent growth sample data. The model predicts stand
heights, diameters, volumes and mean annual increments at different
utilization levels and ages. VDYP uses the ‘Air Method’, which uses
crown closure as the density measure
Falling and bucking for Volume and Decay samples

What is INCOSADA
• INCOSADA supports forest management
» Mapping information, or spatial data,
provides the framework for describing BC's
forest lands and textual data provides the
detail.
•
INCOSADA is a major forestry initiative to create a current, complete and
managed database of information about the land base.
•
This multi-year program will facilitate the creation of a systematic, multi-purpose,
mapping infrastructure for forestry in the public sector.
•
When complete, INCOSADA will provide a standardized set of corporate spatial
and attribute data (i.e., map and text data) with common database structures.
Also, INCOSADA will deliver a single suite of tools to Land Information
Management staff to support file update and management.
•
INCOSADA will meet the requirements of Geographical Information Systems
(GIS) products and viewer tools. Further, INCOSADA will enable the GIS
analysis techniques now required for planning and management of natural
resources.
INCOSADA is...
• Getting FC1 /FIP Files GIS ready.
• Getting responsibility for data sorted out
• Setting standards for tiles / themes
• The data that will be converted will
focus on the following datasets:
 Administrative Boundaries
 Base information – TRIM 1
 Cadastre
 Inventory Administrative Boundaries (ie. PSYU, FIZ,
Region, Compartment)
 Tenure Roads
 Non Tenure Roads
 Tenure information (ie. Exhibit A, Forest Atlas)
 Vegetation Inventory
Name that Decade
“There had arisen a fierce rush to stake timber. Hundreds and
hundreds of men – experienced loggers, inexperienced youth –
blossomed as ‘Timber cruisers’. The woods were furrowed with
their trails. - - They had staked the good timber, and then the poor
timber, and then the places that looked as if they had timber on
them, and then places that lacked appearance.”
Martin A. Grainger – 1905
