This article explores the ecophysiological factors influencing seedling establishment in forest restoration efforts. It examines how a seedling's morphological and physiological characteristics interact with environmental conditions on restoration sites, ultimately determining its success. The article explores how light, temperature, and water availability affect seedling performance, highlighting the challenges posed by extreme conditions like frost or drought and the benefits of optimal growing environments. The critical role of nutrient cycling and competitive vegetation is also discussed, emphasizing that a comprehensive understanding of these interactions is key to applying effective silvicultural practices that maximize seedling growth and ensure rapid forest stand establishment.

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.

This paper explores the opportunities and limitations of forest thinning as a strategy to enhance the resistance and resilience of trees and forests to global change. The authors reviewed existing literature to assess how thinning impacts forest vulnerability to key stressors like drought, fire, insects and pathogens, and wind. While the study identifies several instances where thinning can be beneficial, particularly in mitigating drought and fire risks, it emphasizes that thinning is not a universal solution and its effectiveness varies depending on the specific stressor, forest type, and management practices. The paper highlights the need for more research, especially in underrepresented regions, to better understand the long-term effects of thinning and to develop effective adaptive forest management strategies in the face of increasing global environmental challenges.
