Creating woodland through natural processes: Current understanding and knowledge gaps in Great Britain
Published: 2025-04-30
Subjects: Agriculture, Ecology and Evolutionary Biology, Forest Management, Forest Sciences, Life Sciences, Terrestrial and Aquatic Ecology
1. Creating new woodlands through natural processes, as opposed to traditional tree planting, is expected to result in more structurally diverse, locally-adapted woodlands that enhance the resilience of existing treescapes. However, the outcomes of natural colonisation can be variable, and there is still considerable uncertainty around the ecological processes involved. 2. To address knowledge [...]

Subjects: Biodiversity, Botany, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Forest Biology, Forest Management, Natural Resources and Conservation, Population Biology
Epiphytic lichens are key components of temperate rainforests, where they contribute to forest hydrology, nutrient cycles, food webs, and overall biomass and biodiversity. Despite their ecological importance and sensitivity to environmental change few protections exist for lichen conservation and management. Pseudocyphellaria rainierensis, or old-growth specklebelly lichen, is considered an [...]
Forest restoration treatments increase native plant diversity but open the door to invasion in the Colorado Front Range
Published: 2025-04-08
Subjects: Forest Biology, Forest Management, Terrestrial and Aquatic Ecology
Forest thinning treatments are often done with objectives to re-establish historical forest structure and increase the system’s resilience against future wildfires. But little is known about their long-term efficacy, and effects on understory plant composition. This is especially true in the Colorado Front Range (CFR). We used a before/after control/impact study design to assess the effects of [...]
Non-native plant legacies: site-dependent effects on deadwood fungal community species and functions
Published: 2025-03-28
Subjects: Biochemistry, Biophysics, and Structural Biology, Forest Management, Forest Sciences, Life Sciences, Other Ecology and Evolutionary Biology, Plant Biology, Plant Sciences
1) The introduction of non-native species has consequences for ecosystem functions including deadwood decay. Non-native deadwood is a novel substrate for consumers, such as fungi, which drive large portions of carbon cycling, but their response to a novel substrate may depend on their local communities and surrounding environmental conditions. 2) We quantified decomposition rates, chemical [...]

Forest disturbances are a natural ecological process, but climate and land-use change are altering disturbance regimes at an unprecedented rate, posing significant threats to biological communities and species of concern. Our aim was to develop an automated habitat monitoring system for the Southern Sierra Nevada Distinct Population Segment of fisher (Pekania pennanti) in California, USA to [...]
Assessing UAV direct-seeding for tropical forest restoration: carbon sequestration potential and cost efficiency
Published: 2025-02-14
Subjects: Forest Management, Life Sciences, Other Forestry and Forest Sciences
Introduction: Afforestation, Reforestation, and Revegetation (ARR) projects are key to global reforestation targets under frameworks like the Paris Agreement and the UN Decade on Ecosystem Restoration. However, manual planting remains labor-intensive and costly, limiting large-scale restoration. UAV-assisted direct seeding offers a scalable alternative, yet its carbon sequestration and [...]
Improving Aboveground Biomass Estimates with 3D Tree Crown Parameters from UAV-LS in Beech Forests
Published: 2024-12-18
Subjects: Forest Management, Forest Sciences, Life Sciences
Accurate estimates of aboveground biomass (AGB) are essential for forest policies to reduce carbon emissions. Unmanned aerial laser scanning (UAV-LS) offers unprecedented millimetric detail but is underutilized in monitoring broadleaf Mediterranean forests compared to coniferous ones. This study aims to design and evaluate a procedure for AGB estimates based on the predictive power of crown [...]
Comparing two ground-based seed count methods and their effect on masting metrics
Published: 2024-10-02
Subjects: Forest Biology, Forest Management, Forest Sciences, Plant Biology
Masting, i.e. interannually variable and synchronized seed production, plays a crucial role in forest ecosystems, influencing wildlife dynamics, pathogen prevalence, and forest regeneration. Accurately capturing masting variability is important for effective forest management, conservation efforts, and predicting ecosystem responses to environmental changes. The adoption of low-cost methods [...]
Quantifying life-history trade-offs in diameter growth for tropical tree species from a large urban inventory dataset
Published: 2024-06-11
Subjects: Forest Biology, Forest Management, Horticulture, Integrative Biology, Plant Biology, Population Biology
Trees are important ecosystem service providers that improve the physical environment and human experience in cities throughout the world. Since the ecosystem services and maintenance requirements of urban trees change as they grow in time, predictive models of tree growth rates are useful to forecast societal benefits and maintenance costs over a tree’s lifetime. However, many models to date are [...]
The role of deadwood in the carbon cycle: Implications for models, forest management, and future climates

Subjects: Biogeochemistry, Earth Sciences, Ecology and Evolutionary Biology, Environmental Sciences, Forest Biology, Forest Management, Forest Sciences, Life Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Plant Biology, Plant Sciences, Terrestrial and Aquatic Ecology
Deadwood represents a significant carbon pool in forests and savannas. Although previous research has focused mainly on forests, we synthesise deadwood studies across all ecosystems with woody vegetation. Storage and release of carbon from deadwood is controlled by interacting decomposition drivers including biotic consumers (animals, microbes) and abiotic factors (water, fire, sunlight, [...]
Leveraging surf breaks to expand conservation of carbon-dense coastal ecosystems
