Using satellites to capture regeneration on harvested forest areas reveals regional differences
Up-to-date monitoring of forest disturbance and recovery at large scales is a critical challenge. BERA research partners at the ABMI developed a repeatable, scalable, and adaptable workflow for capturing broad patterns in post-harvest forest regeneration using long-running satellite image archives and Google’s Earth Engine platform. Their work produced a public dataset of Alberta-wide harvest area spectral regeneration available at www.abmi.ca.

Linear Disturbances Shift Boreal Peatland Plant
Communities Toward Earlier Peak Greenness
BERA researchers are using smartphone technology to understand the effects of seismic lines on peatland functioning, revealing important phenological shifts and greater CO2 uptake in disturbed areas. Read the manuscript here.
Towards Drone-Based Establishment Surveys
BERA researchers at the Canadian Forest Service and University of Calgary are teaming up to shows how drones could potentially replace ground-based seedling establishment surveys, reducing costs, increasing survey area, and avoiding trampling over restored terrain. One important step towards that process involves using drones to measure seedling height. Read the manuscript here.
Seismic Line Geometry Affects Tree Regeneration
Seismic Line Treatments Alter Peatland Soil Properties
Open Access Software Tools for Researchers and Land Managers
Most linear-feature databases work fine for cartographic purposes but are not up to the demands of detailed research and restoration planning. Researchers in BERA’s Remote Sensing Team tackled this problem by developing the Forest Line Mapper: a free, open-access software kit you learn more about here.
Fires Help Erase Seismic Lines in Peatlands
Seismic lines alter a host of ecosystem processes in the boreal forest, and many of those lines are in a state of arrested succession. Restoration managers have to choose: active restoration (mounding, planting, other treatments) or passive (leave for natural)? Researchers in BERA’s Vegetation Team are helping to understand the role of fire in this equation. Read about some of their work here.
