Canada’s diverse landscapes and ecosystems play a critical role in regulating carbon cycling, water and nutrient dynamics, biodiversity, and climate. Understanding these interconnected processes across spatial and temporal scales is essential for strengthening ecosystem resilience and advancing nature-based climate solutions. This session will highlight research conducted through large-scale projects, coordinated research networks, and other collaborative initiatives across Canada. We invite contributions demonstrating how distributed field observations, shared infrastructure and datasets, remote sensing, and modelling are being integrated to understand ecosystem structure, function, and responses to environmental and anthropogenic change. Contributions may span individual monitoring sites, multi-institutional networks, and nationally coordinated programmes across disciplines and ecosystems. The session will demonstrate how research conducted across regions and scales can inform climate mitigation and adaptation, biodiversity conservation, and sustainable ecosystem management, translating ecological knowledge into actionable solutions for ecosystems and society.
