Kamloops TSA - Forest Health Strategy Thompson Rivers Forest District April 2017 Executive Summary The Kamloops TSA Forest Health Strategy has for the most part not been changed for this year. There have been minor edits, as well as some additions. It is expected that over the next few years, that there will be more information added with respect to; Stand Establishment Decision Aids, strategies for pests in young stands, stocking standards related to forest health factors and climate change adaptation strategies. The changes of note this year are: • New Root disease guidance Document Update on Bark Beetles in Kamloops TSA: • Areas affected by Western balsam bark beetle have dropped to less than half of 2016 levels resulting in 59,730 hectares infested. The decline is due to lower red attack rates, with stands in the northern portion of the TSA, around Dunn Peak, Trophy Mountain, and Wells gray Park and the upper North Thompson being the most affected. • Spruce beetle – attack levels remain high, with 9,770 hectares identified, the largest new infestation moving into uninfested stands in Wells Gray Park around Kostal Lake, McDougall Lake, and the west arm of Murtle Lake, Angus Horn Creek and the Upper Clearwater River. • Douglas fir beetle – the area affected by Douglas fir beetle more than doubled, to 3,100 hectares in 362 patches and 1,290 smaller spot infestations. The attack is widespread across the southern portion of the TSA with significant red attack in the Wells Gray Park, Barriere River, Adams Lake and Pinantan Lake areas. Douglas fir beetle is anticipated to build in fire damaged trees along the margins of the Elephant Hill, Thuya Lakes and Dunn Lake fires where there is variable burn severity and low intensity ground fires. • Mountain Pine beetle activity was limited to a single spot of 5 trees near Bush Lake. Update on Defoliators: • Two-year Cycle budworm has increased from 24,635 hectares in 2016 to 32,400 hectares in 2017 despite being an off year. The majority of the damage was in the Mad River, Raft River, Stevens Lake, Trophy Mountain, Raft Peak and TFL 18 areas. Moderate defoliation was on over one third of the stands with the rest classified as light. • Douglas Fir Tussock Moth- 15 hectares of defoliation were observed south of Heffley Creek, east of Hwy 5. Ground checks noted many new egg masses which will result in an expanded population in 2018. • Aspen Serpentine leafminer defoliation fell by 80% to 4,510 hectares. • Birch leafminer was mapped on 90 hectares near Adams Lake. Update on Balsam Woolly Adelgid in the Southern Interior: • Balsam woolly adelgid (BWA) was surveyed in 2017 by Don Heppner with the sites selected by Lorraine Maclauchlan and Kevin Buxton. • The results of the survey found BWA in Mine Creek and Juliet Creek widespread and well established, Community Lake Recreation Site with gouting on understory trees and 15 km Badger Lake FSR with BWA and gouting on understory trees. BWA was found on the Darlington FSR with moderate to heavy infested trees from 13 km to 24 km. BWA was found at intervals along the Surrey lake FSR to 13 km.

It covers approximately 2.8 million hectares (including Wells Gray Provincial Park and excluding tree farm licences). The TSA Timber Harvesting Landbase (THLB) is dominated by lodgepole pine, Douglas-fir, spruce, and sub-alpine fir. Smaller areas are dominated by cedar, hemlock and deciduous species. The Strategy is guided by, and aligned with, the Ministry of Forests Lands and Natural Resource Operations and Rural Development (MFLNRORD) Provincial Forest Health Strategy, the Forest Health Program and the Forest Health Implementation Strategy.1 The intent of the Strategy is to provide Forest Professionals2 with guidance on, and information about forest health agents in the TSA. The objective is to enhance ecosystem health thereby improving forest resiliency and sustainability. This is consistent with the vision statement of the Kamloops Sustainable Forest Management Plan and the Kamloops Land Resource Management Plan. This document does not contain a conclusive list of all pests. The pests that have been included are considered to have the potential for significant impacts &/or frequently occur within the TSA. Understanding the implications of climate change for forest health is a focus of the Ministry Forests Lands and Natural Resource Operations and Rural Development (MFLNRORD). Climate 3 change strategies for forest pests can be found in Forest Health and Climate Change. 1 Link to the Provincial Forest Health Strategy, the Forest Health Program and the Forest Health Implementation Strategy: http://www.for.gov.bc.ca/hfp/health/ 2 http://www.abcfp.ca/ 3 http://www.for.gov.bc.ca/rsi/ForestHealth/index.htm Updated July 13, 2018 Page 6 of 35 \\granite\work\srm\kam\Workarea\ksc_proj\p12\p12_0013_FLNRO_Rsrc_mgmt_grp_misc\DKA_forest_health\fin\2012 Forest Health Strategy draft March 09 2012.doc 2.0 Guiding Principles 1. Follow applicable legislation. Augment or identify, rather than reiterate policy and legislation, e.g. FRPA bulletins provide additional guidance.4 2. Remain consistent with and follow guidance provided by regional forest health experts. The Thompson Okanagan Region (TOR) forest health web site contains links to research, contacts, overview data and other forest health information.5 3. Follow guidance provided by the; • Forest Practices Branch6 (e.g., Provincial Forest Health Strategy, Research, etc.) • British Columbia’s Mountain Pine Beetle Action Plan 2006-20117 • Provincial Forest Health Implementation
