Site Productivity

Overview

The site productivity project characterises the timber-growing potential of forested sites across British Columbia. Inventory staff works with clients, ecologists and site-productivity researchers to plan and execute this program. Currently, the Land Based Investment Strategy (LBIS) funds the site productivity project. Its purpose, goals and scope follow those of LBIS. The sections below provide more information on the:

  • LBIS
  • Site productivity strategic plan and annual work plan
  • Provincial site productivity layer

Purpose

LBIS guides ongoing resource investments and short-term targeted investments in B.C.’s natural resources. It realizes environmental sustainability and economic prosperity.

LBIS goals:

  • Manage a portfolio of natural resources to uphold and enhance their value
  • Mitigate impacts due to catastrophic environmental disturbance or human action
  • Administer timely use of B.C.’s natural resources and help achieve economic, social and environmental benefits

Scope

Eligible investment categories and priorities are determined annually using these strategic directions:

  • Ministry service plan goals and objectives
  • Key priorities and projects described in annual regional and provincial work plans
  • Other government commitments described in the throne speech, the BC Jobs Plan, specific initiatives, minister’s priorities, etc.

Some existing LBIS projects also have strategies that prioritise work to be completed over many years. Follow the link under Associated Documents below for more detailed information about LBIS.

Project Selection

Site productivity projects include:

  • SIBEC (Site Index by Ecosystem)
  • PEM (Predictive Ecosystem Mapping)
  • TEM (Terrestrial Ecosystem Mapping)
  • SIA (Site Index Adjustment).

The principal criterion for selected projects was their alignment with the objectives of LBIS as described in the Land Based Investment Strategy.

Additional considerations that guided project selection:

  • Improve data availability
  • Timely delivery
  • New before improve
  • Complete projects
  • Mapping (preferably spatial information)
  • Multiple benefits across a number of business areas; for example, timber supply review, silviculture, habitat modelling

The strategic project plan provides tables summarising recommended projects, in order of priority, for the 2014 through 2016 fiscal years. The strategy includes a mix of “quick wins” and key multi-year investments.

Emphasis on SIBEC & PEM

The site productivity work focuses on developing SIBEC and PEM, as these provide the most efficient long-term investment. SIBEC can be used across multiple administrative units and its data can be used for multiple purposes.

A stable BEC classification is a fundamental precursor to efficient investments in PEM, TEM and SIBEC. Updates to BEC are required before site productivity actions can be co-ordinated in many of the priority and non-priority units.
