NEW SPECIAL ISSUE: Assisted Migration and Forest Seed Transfer

We are launching the topical collection “Assisted Migration and Forest Seed Transfer”. This special issue will gather articles investigating potential chances and risks of assisted gene flow and assisted migration of forest tree populations in climate change.

Combining low-density LiDAR and satellite images to discriminate species in mixed Mediterranean forest

Using a combination of remote sensing data, Pinus pinaster Ait. and Pinus pinea L. were distinguished at individual tree level in mixed Mediterranean stands with over 95% accuracy. This approach is easily applicable over large areas, enhancing

Tree and stand level estimations of Abies alba Mill. aboveground biomass

We provided a complete set of tree- and stand-level models for biomass and carbon content of silver fir Abies alba. This allows for better characterization of forest carbon pools in Central Europe than previously published models. The

Base cation dynamics in rainfall, throughfall, litterflow and soil solution under Oriental beech (Fagus orientalis Lipsky) trees in northern Iran

Fluxes of base cations were studied in an Oriental beech forest and an adjacent forest gap. The fluxes of base cations in throughfall, litterflow, topsoil and subsoil solution were higher in a mixed Oriental beech forest compared

Opportunities and challenges for an Indonesian forest monitoring network

Permanent sampling plots (PSPs) are a powerful and reliable methodology to help our understanding of the diversity and dynamics of tropical forests. Based on the current inventory of PSPs in Indonesia, there is high potential to establish

Performance of alternative spatial models in empirical Douglas-fir and simulated datasets

Based on an empirical dataset originating from the French Douglas-fir breeding program, we showed that the bidimensional autoregressive and the two-dimensional P-spline regression spatial models clearly outperformed the classical block model, in terms of both goodness of

Axial diffusion of respired CO2 confounds stem respiration estimates during the dormant season

Efflux-based estimates of stem respiration in oak trees during the dormant season were biased by axial diffusion of locally respired CO2. Light-induced axial CO2 diffusion along the stem due to woody tissue photosynthesis may lead to equivocal

Key lessons from resistant tree breeding programmes in the Northern Hemisphere

To inform emerging initiatives, we explored five programmes that aimed to develop trees resistant to specific pests or pathogens. These case studies show resistant tree programmes are a medium to long-term approach requiring sustained investment, and can

Implementing forest landscape restoration under the Bonn Challenge: a systematic approach

There is no one-size-fits-all way to successfully implement forest landscape restoration (FLR). Complex socio-ecological systems present challenges and opportunities that can best be met with a systematic framework for designing, planning, steering, and monitoring FLR projects to

On the need to consider wood formation processes in global vegetation models and a suggested approach

Dynamic global vegetation models are key tools for interpreting and forecasting the responses of terrestrial ecosystems to climatic variation and other drivers. They estimate plant growth as the outcome of the supply of carbon through photosynthesis. However,
