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 1990sJohn Parminter, Research Branch, B.C. Forest Service November 2000

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

‘Close attention to Coast timber had caused no value to be placed on Interior timber but transportation systems will give this timber its true value’

Mapping Options

1) Use Mapview on the WEB

2) Use INCOSADA REP tile

3) Clover Point Cartographics

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

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)

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
