This paper is a comprehensive review of variable retention forestry as it has been implemented and studied in British Columbia over the past two decades, focusing on its effectiveness for biodiversity conservation. It traces the origins and evolution of VR in response to concerns about traditional clearcutting, detailing its adoption by major forestry companies and its integration into provincial regulations and land use plans. The authors examine the ecological outcomes of VR, including its impacts on forest structure, wind damage, tree growth, understory vegetation, and various animal groups like birds and invertebrates, often drawing upon long-term monitoring projects and adaptive management experiments. The review aims to synthesize the lessons learned about balancing timber production with biodiversity goals through VR, offering insights into best practices and future directions for forest management in BC and potentially other regions.

This paper synthesizes the disparate groundwater responses to wildfire, noting that post-fire effects range from significant increases to decreases in water fluxes like recharge and baseflow. The authors evaluate this variability across five primary categories: climate, vegetation, hydrogeology, fire characteristics, and the cryosphere, focusing on both short-term and intermediate recovery periods. A critical finding is that post-wildfire responses often align with hydroclimatic settings where water input and evaporative demand are out of sync, while the pre-wildfire groundwater regime significantly influences the expected outcome and recovery trajectory. This paper provides a collection of testable hypotheses and identifies key areas, particularly the influence of snow dynamics and cryospheric processes, for future monitoring and modeling efforts to improve the prediction of groundwater recovery after fires.
