One plan to rule them all: Applying the conservation standards to coordinate restoration of Canada’s degraded endangered whitebark and limber pines across jurisdictions

Western Canada hosts two endangered trees: whitebark pine (Pinus albicaulis) and limber pine (Pinus. flexilis), subalpine and montane keystone species. Populations have declined sharply, primarily due to a virulent introduced pathogen (Cronartium ribicola) causing white pine blister rust. Other threats include mountain pine beetle (Dendroctonus ponderosae), human impacts, changes to historical fire regimes, and climate change. Restoring ecological function in degraded high-elevation pine ecosystems requires decades of targeted actions at multiple scales: from genes associated with disease resistance, to individual tree seed collection, to stand-level assessment and planting, to landscape connectivity planning, to establishing seed orchards for climatically adapted seed zones. Successful recovery across the species’ Canadian ranges requires partners to share resources and data, tailoring treatments to ecological and demographic conditions, and consistent tracking. Applying the Conservation Standards framework, the Whitebark Pine Ecosystem Foundation of Canada coordinates partners across jurisdictions, focusing limited resources for maximum recovery impact. Progress is tracked towards targets, goals, and objectives. Jurisdictional achievements and national progress are reported annually. Indicators and objectives are adjusted to reflect emerging knowledge and adaptive management results. We present an overview of the Conservation Standards application to Canadian whitebark and limber pine recovery, and progress to date on key benchmarks.
