The Last Spruce Grove

Old Growth, New Conflict

By Celeste A. Leander

The Last Spruce Grove


 

Abstract

This case study follows a drama that unfolded around a stand of Sitka spruce trees (Picea sitchensis) on Vancouver Island, British Columbia. The stand held significant historical and cultural significance, particularly to the local first-nations band, but grew on privately-held land. The stage was thus set for confrontation when the landowners expressed their interest in harvesting the valuable lumber. Students are introduced to differing concepts of "old growth" before determining stake-holders in this true story. They hear real concerns presented by many of those affected in a mock town-hall meeting. Students discuss consequences to disrupting an intact stand of old growth forest, including those to the neighboring waterways and to several rare species. Finally, students work in small groups to predict a successional pathway when a secondary disruption such as logging occurs. Originally developed for a first-year science course as part of the biology unit focusing on ecology, the case can also be used in a general biology course with an ecology or conservation curriculum, or in an undergraduate ecology course.

Overview

Objectives

  • Compare definitions of "old growth" and discuss when each might be used.
  • Discuss structure and composition as factors defining successional stages of a forest.
  • Identify stakeholders in a conservation issue.
  • Predict consequences of clear-cut logging on the community and nearby waterways.
  • Evaluate where a stand of trees likely sits in a succession pathway.
  • Predict the return of this ecosystem, based on either Gleason's or Clements' hypothesis for community structure.
