Two years of Landscapes in Motion: What have we learned?

Two years and countless hours of field, lab, and computer study by three diverse research teams have added up to new insights on the fire history of Alberta’s Southern Rockies. One of the key findings of the Landscapes in Motion research program to-date is that fire regimes in the Southern Rockies are complex, including low-severity burns and historical influences of fire suppression and Indigenous cultural burning. In this post, project coordinator Dr. David Andison and fire regime team lead Dr. Lori Daniels share what the implications of these findings might be, what questions remain to be answered, and where our work is going next.

Why model partial mortality?

Why model partial mortality?

One potential consequence of mixed severity fire regimes is that some trees may survive lower intensity fires. This phenomenon is called “partial mortality”, and it can have a variety of consequences for what the landscape looks like and becomes after a fire. When trees survive, they may offer refuge for wildlife, help speed up revegetation by producing seeds, and/or help to maintain the presence of other types of vegetation like lichens. In this blog post, we discuss how the Landscapes in Motion modeling team is studying partial mortality in the Southern Foothills of Alberta using simulation models, and why this research is important for understanding the fire history of this region.

Recent study in Southern Alberta shows loss of grasslands across the landscape, with implications for fire risk and fire history

A recent study led by Landscapes in Motion collaborator Dr. Chris Stockdale shows that since the early 1900s, 25% of grasslands have been lost in a large area of Alberta’s Southern Rocky Mountains. Our blog team sat down with Dr. Stockdale to discuss the implications of these findings, the exciting opportunities of oblique photography, and the connections between this research and the Landscapes in Motion project. Dr. Stockdale is currently a Fire Research Scientist with the Canadian Forest Service.

Bringing oblique photography and wildfire research together using viewsheds

What are viewsheds, and why use them? With the Landscapes in Motion teams now analyzing data and sharing the results, our teams are starting to explore new ways of collaborating and combining datasets. Here we share some insights on the process from a collaborator with the Oblique Photography Team, Mountain Legacy Project researcher James Tricker.

A Wildfire Story: Decoding the Past with Tree Scars

Disturbances like fires and insect infestations literally leave a mark on trees, creating scars in annual tree rings. Since our research team is interested in the fire history of the landscape, we need to be able to tell fire scars reliably apart from scars left by insects. With two full field seasons now in the books, Dr. Cameron Naficy’s Fire Regime Team have become local experts in this challenging task. In this post, we describe the challenges of distinguishing scar types, provide some insights on how our team solves these puzzles, and explore the important connections between insects and fire.

Placing oblique photos on the map

The Landscapes in Motion Oblique Photo Team has the daunting task of scaling mountains to repeat photographs taken up to a century ago by land surveyors. In previous posts we’ve described how these intrepid researchers locate sites, line up their photos, and what it’s like working in the field. With the summer fieldwork over, we now get to learn how they are harnessing technology to analyze landscapes in these repeat photographs and collect data from them.
