Climate Change Vulnerability Assessment and Adaptation Planning to in Prairie Forests

Mark Johnston and Elaine QualtiereSaskatchewan Research Council

March 15 2011


General areas of vulnerability• Changes in species distributions

• Fire activity

• area burned

• frequency and intensity

• Insect outbreaks

• endemic species (e.g. SBW, FTC)

• exotics (e.g. EAB, MPB)

• Productivity

• Operations

• season of frozen ground

By 2050: 2X increase

By 2100: 3-5X increase

- Climate data used to calculate FWI

- Statistical relationship between FWI and fire activity

- Future data from CGCM1


HFI map for Duck Mountains, prepared for LP’s Forest Management Plan, 2006

• Analysis using CFS Spatial Fire Management System (new version soon!)

• Climate data from CRCM

• Fuel types re-classified from LP forest inventory

• Pink and red indicate fuel types where fire will be difficult to suppress

• Did similar analysis for Mistik FMA in NW SK


Suppression difficult

Suppression impossible


• Endemic species outbreaks likely to increase but details are poorly understood

• Exotics also likely to increase but impacts greater because no resistance

• New MPB scenarios seem to be leaning toward poor winter survival, the apocalypse may be avoided!

• Need to examine organization’s adaptive capacity:

– Awareness – Technology availability– Resources– Institutions– Human capital– Social capital– Risk management– Information management

Human Dimension


• Policy assessment – does current policy value

– Innovation

– Flexibility

– Looking forward

• Does policy welcome new thinking from outside, e.g. industry, producers?

• Can policy be changed easily when required?

Human Dimension


• Based on expert opinion and what has worked in the past

• Screen according to future scenarios

• Prioritize using e.g. CCFM Criteria and Indicators or other benchmarks for SFM

LANDIS-II Philosophy: Homogeneity

LANDIS assumes homogeneity at multiple scales:

Sites = single cells

Ecoregions = 1 or more cells, typically defined by climate and soils. Need not be contiguous.

Case Studies• Island Forests in SK

– Focus on interacting sources of vulnerability on sensitive landscapes

– Fire, insects, drought, productivity

• Alberta Case Study

– Lit review to support provincial vulnerability assessment

– Possibility of more work next year

• Manitoba Case Study

– Tree ring analysis to link tree growth and climate variables (with University of Winnipeg)
