The term "triad" in forestry refers to a landscape management regime composed of three parts: (1) intensive plantation management, (2) ecological forest reserves, and (3) matrix forests managed for multiple uses following the principals forestry. In this paper we review sociohistorical academic context triad related concepts. We argue that has potential minimize trade-offs between meeting global demand timber products ecosystem services are typically under-provisioned intensively production. should include monitoring outcomes from each types so specific practices allocation plantations, reserves can be adapted changing societal conditions. describe guidelines implementing may assist policy makers managers putting theory into practice provide real-world example adoption Nova Scotia, Canada.

to understand how wildfire risk policies are designed mitigate1 the impacts of wildfires. Wildfires a growing threat in many parts world, posing significant risks human life, and environment. In recent years, wildfires have increased, driven largely by climate change, activity, changes land-use patterns. Wildfire adaptation mitigation measures vary widely between countries regions around world. Therefore, it is essential develop comprehensive policy approach mitigate promote sustainable forest land management practices. This article aims provide insight into policies, implementation actions, their effectiveness describing centered mainly on exclusion mitigation. examines existing wildfire-related relevant literature based 10 systematic factors. Further exploring these can be enhanced meet challenges coming years for six European (Cyprus, France, Greece, Italy, Portugal, UK) as well Australia, Canada, USA, South Africa. The status quo, perceived strengths, weaknesses, recommendations from key-informants were presented enhance each country. analyses current fire-prone countries, highlighting regional variations need an integrated strategy. It offers country-specific participants viewpoints, coordinated efforts management.

Analysis of forest fire patterns and their relationship with climate variables in Alberta's natural subregions

Forest fires are significant ecological and environmental phenomena that can be influenced by various climatic factors. This study used fire point records from the Canadian National Fire Database (CNFDB) interpolated climate data, which include minimum maximum air temperature, average relative humidity, precipitation for each subregion of Alberta, Canada, to analyze patterns relationships forest variables using trend analysis anomaly detection methods.

Linking Fire, Food Webs, and Fish in Stream Ecosystems

As wildfire regimes shift, resource managers are concerned about potential threats to aquatic ecosystems and the species they support, especially fishes. However, predicting fish responses can be challenging because wildfires affect via multiple pathways. Application of whole-ecosystem approaches, such as food web modeling, act heuristic tools that offer valuable insights account for these different mechanisms. We applied a dynamic simulation model mechanistically linked stream trophic dynamics myriad effects have on riparian at local reach-scale. simulated how severity may influence short- (months years) long-term (years decades) periphyton, invertebrate, biomass in forested headwater streams western Pacific Northwest (USA). In many cases, increased modeled over both long-time periods. varied extensively their direction (that is, positive or negative), magnitude, duration depending fire severity, time since fire, level. The shapes response trajectories were sensitive predicted water temperature, canopy cover, shading, instream turbidity. Model simulations suggest single could result wide range ecosystem responses, watersheds with mixed burn severity. Our analysis highlights utility like improving our understanding mechanisms linking webs, identifying contexts where fires deleterious impacts

Forest restoration and fuels reduction work: Different pathways for achieving success in the Sierra Nevada

Abstract Fire suppression and past selective logging of large trees have fundamentally changed frequent‐fire‐adapted forests in California. The culmination these changes produced that are vulnerable to catastrophic change by wildfire, drought, bark beetles, with climate exacerbating this vulnerability. Management options available address problem include mechanical treatments (Mech), prescribed fire (Fire), or combinations (Mech + Fire). We quantify forest structure composition, fuel accumulation, modeled behavior, intertree competition, economics from a 20‐year restoration study the northern Sierra Nevada. All three active (Fire, Mech, Mech Fire) conditions were much more resistant wildfire than untreated control. included lowest surface duff loads hazards. low hazards beginning 7 years after initial treatment had lower tree growth controls. only competition somewhat similar historical California mixed‐conifer was Fire, indicating stands under would likely be resilient enhanced stressors.

Guiding principles for transdisciplinary and transformative fire research

Abstract Background Managing landscape fire is a complex challenge because it simultaneously necessary for, and increasingly poses risk to, societies ecosystems worldwide. This underscores the need for transformative change in way live with manage fire. While researchers have potential to act as agents of change, practice, ability affect often constrained by siloed biased expertise, rigid decision-making institutions, vulnerable social-ecological systems where urgent rather than long-term solutions are prioritized. Addressing these challenges requires more holistic equitable approaches research that promote new models transdisciplinary thinking, collaboration, practice. Results To advance this challenge, we propose four principles conducting research: (1) embrace complexity, (2) diverse ways knowing fire, (3) foster learning, (4) practice problem-centered research. These emerged from our experience group early-career who embedded within motivated today’s British Columbia (BC), Canada. In forum piece, first describe then apply two case studies: BC, settler-colonial context experiencing increased size, severity, impacts wildfires, ECR discussion group, space collective learning transformation. doing so, present unique contribution builds on existing efforts develop frameworks demonstrates how application can transformation towards coexistence local global scales.
