Silviculture Working Group

The CRIT Silviculture Working Group (CSWG) was established in 2004 to address issues related to silvicultural systems and partial cut harvesting.  The CSWG is equally represented by members from both industry and government that have significant experience and/or interest in the practice of silviculture.  The CSWG deals with silviculture issues as directed by the broader CRIT such as FRPA related stocking standards and silvicultural systems. 

 1. Terms of Reference

The CSWG has developed their terms of reference, updated on March 30, 2009.

2. Professional Networking Under FRPA

As a member of the CRIT Silviculture Working Group, Paul Barolet has written an article (Professional Networking under FRPA ) that describes CRIT, current CRIT issues and what CRIT and the Silviculture Working Group is doing to promote professional networking under FRPA. The article has been published in the Association of BC Professional Forester's BC Forest Professional magazine, September-October 2007 edition.

3. Silviculture Systems and Stocking Standards

In May 2006 the CSWG released a document entitled Silvicultural Systems and Partial Cut Harvesting Issues in the Coast Forest Region Discussion paper”.  The purpose of this paper is to review the issues, develop possible solutions and provide recommendations pertaining to silvicultural system issues. The CSWG has also developed FSP stocking standard guidance and messaging in 2006 and is developing a discussion paper related to FSP stocking standards.

4. Management of Hardwood Species

In 2007, as part of the Coast Forest Action Plan, the CRIT Silvicultural Working Group (SWG) was tasked with drafting a strategy for the management of hardwood species. To that end, the working group has now completed development of the Hardwood Management in the Coast Forest Region strategy document (and supporting Hardwood Management Strategy Co-chair endorsement & Hardwood Management Strategy RED endorsement documents). This strategy was jointly drafted by the industry and government members of the CRIT Silviculture working group, with the assistance of MFR and licensee experts in the field of hardwood management. This document has been endorsed by CRIT and the Regional Executive Director of the Coast Forest Region. The focus is on alder management as this is the species with the broadest potential for hardwood management on the coast and represents the most current knowledge. It supports the expansion of hardwood management above its current levels on the coast.

Since the release of the Hardwood Management in the Coast Forest Region strategy document, the SWG has developed and been delivering an implementation strategy that includes delivery of workshops throughout the coast. Part of the strategy is to monitor the implementation of the strategy contained in the document. Based on monitoring results, the SWG has developed the Hardwood Management in the Coast Forest Region Five year Results (2009-2014) report. This report is a collaborative product prepared by members of the SWG and various Coastal Broadleaf Management Specialists. The objective of the report is to inform CRIT, Industry, the Chief Forester and others about status of broadleaf management across the coast over the past 5 years. The report focuses on the identified trends in broadleaf management and compares these trends against the interim target contained in the document. The report also identifies challenges and impediments associated with implementation of the strategy and makes recommendations with respect to next steps in continued implementation.

5. Silvicultural Systems Monitoring

Further to the Silvicultural Systems and Partial Cut Harvesting Issues in the Coast Forest Region Discussion paper, the CSWG has developed monitoring protocols that allow industry and government members to carry out joint field inspections against the key principles contained within the discussion paper. In 2006 through 2008, the CSWG has carried out joint industry and government field monitoring on cutblocks within various coastal districts. Each year a summary report of the results of monitoring is produced for CRIT. The results of this monitoring are summarized in the "Silvicultural System and Partial Cut Harvesting Issues in the Coast Forest Region 2007/2008 and 2008/2009 Monitoring Results" report.

6. Silvicultural Systems Summary Messaging

A number of years ago the Coast Region Leadership Team (now Regional Management Team) challenged the CRIT to improve the application of silvicultural systems in areas with high levels of dispersed over-story retention. Significant progress has now been accomplished (as evidence of the information provided on this web page). A brief summary of accomplishments was provided to the Coast Region Leadership Team and the Chief Forester under covering memorandum to improve application of silvicultural systems in areas with high levels of dispersed over-story retention.

7. Chief Forester Recognition Letter

The Chief Forester has acknowledged that there is a variety of planning and practice issues associated with silvicultural system and partial harvesting applications within the Coast Forest Region and recognized the efforts of the CSWG to address these issues in his letter addressed to coastal licensees, industry associations and CRIT.

8. Single Entry Dispersed Retention System Stocking Standards

The Silviculture Working Group completed work on the "Single Entry Dispersed Retention System Stocking Standards Discussion Paper" for use within the Coast Forest Region in November of 2009. The purpose of this discussion paper is to provide a stocking standard framework for a Single Entry Dispersed Retention Standard Retention System for use within the Coast Forest Region. This stocking standard guidance is meant to replace the multi-storied stocking standard, referenced in the Ministry of Forests and Range (MFR) publication titled: Reference Guide to Forest Development Plan Stocking Standards. This document is meant to be used as guidance material for practicing professionals and advice to decision makers.

This discussion paper is the first in a series of papers to address stocking standard related issues.

As follow-up to the discussion paper entitled Single Entry Dispersed retention Stocking Standard Framework (see above) the CRIT Silviculture Working Group and associated resource specialists have developed the Single Entry Dispersed Retention Stocking Standard Framework Implementation Guide. The purpose of the guide is to help practitioners in the implementation of the Single Entry Dispersed Retention Stocking Standard framework operationally. The guide incorporates feedback from participants at two field-based workshops and is intended to compliment and support the framework described within the discussion paper.

Since 2011, the SWG developed new Deviation from Potential (DFP) tables which have been developed and calibrated for coastal old growth cedar/hemlock stands. In addition, the SWG delivered a number of SEDRSS workshops across the coast. Based on this work, the SWG has updated the guide to include the new DFP tables and various workshop learning's. The Single Entry Dispersed Retention Stocking Standard Framework Implementation Guide Version 2.0 is designed to provide useful information related to implementation of SEDRSS; however, it is stressed that this is not to be interpreted as Government direction or policy. It is hoped that the information contained in the document will serve to assist forest professionals in making partial cut harvesting stocking standard recommendations and decisions.

The Silviculture Working Group has now completed an update to the September 2011 Single Entry Dispersed Retention Stocking Standard (SEDRSS) Framework Implementation Guide Version 2.0 to include a SEDRSS stocking standard for second growth coastal Douglas-fir Appendix 3: Coastal Second Growth Douglas-fir (Fdc) Retention Stocking Standard SEDRSS-Fdc (Appendix 3).

The attached SEDRSS Appendix 3 incorporates new Deviation from Potential (DFP) tables, which have been calibrated for coastal second growth Douglas-fir stands in the Coastal Western Hemlock and Coastal Douglas-fir biogeoclimatic zones. These Douglas-fir SEDRSS standards are based on field testing on a number of partial harvest sites within the Fraser TSA and the Roberts Creek partial harvest research trial on the sunshine coast.

9. Opportunity Harvesting

The Forest Practices Board, Special Investigation Report #20 titled High Retention Harvesting and Timber Sustainability on the British Columbia Coast (2008:revised January 2009) recommended that the Ministry of Forests and Range (now Forests, Lands and Natural Resource Operations) develop policy relocated to 'opportunity cuts' on sites where there is no expectation of future yield. To this end, the SWG developed the Opportunity Harvesting in British Columbia's Coast Forest Region: Options Paper for the Ministry of Forests and Range April 19, 2010. This document was endorsed by CRIT during the June 24, 2010 meeting and forwarded to the West and South Coast Regional Management Teams for endorsement decision.

10. Roosevelt Elk and Reforestation

Under the former Ministry of Forests and Range (now Forests, Lands and Natural Resource Operations) Quick Win process, forest tenure holders identified Roosevelt Elk translocation and population increases for significantly increasing the failure rate of meeting their reforestation obligations. In response, the SWG developed the Roosevelt Elk Impacts on Reforestation: Mitigation Options paper dated June 29, 2011. The options paper and a work plan to address the paper's recommendations were endorsed by the Coast Operations Issues Forum on September 7, 2011. CRIT is in the process of implementing the work plan in response to the options paper recommendations.

CRIT has developed the Exemption from Obligation to Establish a Free Growing Stand Due to Damage by Roosevelt Elk Guidance document for the purpose of addressing significant reforestation damage due to Roosevelt Elk. This document provides information and guidance for consideration when preparing or reviewing a request for exemption under Forest Planning and Practices Regulation (FPPR) section 91(1) from the obligation to establish a free growing stand as specified under Forest and Range Practices Act (FRPA) section 29 and 29.1.

11. Silviculture Practices Influence on Timber Supply Analysis

There are strong linkages between silviculture practices, information collected and reported to RESULTS and timber supply analysis There are many complex and dynamic elements at play when considering silviculture in relation to timber supply. In order to manage the timber resource value over time, forest professionals must have a grounded understanding of how these factors and treatments can influence timber supply and their role in influencing these silviculture components over time.

In an effort to support forest professionals, the SWG has completed development of The Importance of Silviculture in Timber Supply Analysis, a Coastal Perspective discussion paper.

This paper has two objectives:

-          To demonstrate the importance of silviculture in timber supply analysis, and

-          To provide resource professionals with an understanding of the importance of their role in determining, delivering, and monitoring silviculture practices and the effort this will have on timber supply analysis

The content of the discussion paper represents common understanding of the topic as compiled by forest professionals working in this sector. The discussion paper will be of interest to forest professionals involved in timber supply analysis, RESULTS reporting, growth and yield analysis, silviculture surveys, seed supply, silviculture strategic planning, forest regeneration, forest health and forest stand management.
