In the middle of a forest reserved for timber harvesting on Washington’s Olympic Peninsula, Mark Elbroch and two other members of the Olympic Cougar Project prepared to investigate a likely cougar den. They were tipped off to its location by a young female they’d fitted with a GPS collar and nicknamed Scalp last year. Scalp’s collar connects with satellites to calculate her movements, seen as red track lines on the team’s GPS devices. These cougar experts had a pretty good idea what the seemingly erratic tracks meant. Scalp was going out to hunt deer, then circling back to nurse kittens. It’s legal in Washington to hunt cougars. But the leading cause of death for the project’s study animals is “lethal removal,” the state’s go-to response when a landowner thinks a cougar attacked their livestock or pets. Cougars prefer deer and elk but will settle for smaller animals if they happen upon them, especially when they’re young and still learning the art of hunting larger prey. More often than not, it will cost them their life. Find the story at the link in our bio, our Stories or the “Links to Latest Posts” highlight on our page. 📸: Michael Kodas

Bio‑based construction is entering a decisive implementation phase as new engineering standards drive measurable performance and credibility. The release of a structural manual for bamboo transforms renewable building materials from conceptual to certifiable, giving engineers a shared framework for specification, durability testing and fire safety that aligns with standards for steel and concrete. This move advances sustainable construction by supporting low carbon design and enabling embodied carbon measurement across permanent structures. Integrating bamboo into structural use contributes to whole life carbon assessment and lifecycle assessment processes that underpin sustainable building design and environmental sustainability in construction.

The White Rose Forest’s 25‑year strategy to plant 134 million trees across northern England represents a significant link between green infrastructure and construction supply chains. Managed afforestation aligned with local processing, design standards and resource efficiency in construction has potential to deliver low embodied carbon materials, support net zero carbon buildings and embed circular economy principles. Tree planting tied to sawmilling and design verification increases the availability of green building materials while strengthening the regional circular economy in construction.

These developments tighten the bio‑based supply chain from nature to building performance. Developers are urged to adopt sustainable material specification within procurement to reduce the carbon footprint of construction and achieve whole life carbon targets. Early collaboration with insurers and BREEAM assessors can accelerate certification and enable coherent life cycle cost evaluation. Aligning afforestation programmes with industrial capability, testing and environmental product declarations (EPDs) will solidify the foundation for carbon neutral construction and measurable decarbonising of the built environment.
