Identification and spatial extent of understory plant species requiring vegetation control to ensure tree regeneration in French forests

Key message Fifteen species are most susceptible to require vegetation control during tree regeneration in the range of our study. Among these 15 species, Rubus fruticosus, Pteridium aquilinum, and Molinia caerulea cover each more than 300,000 ha

Classification of forest fuels in selected fire-prone ecosystems of Alberta, Canada—implications for crown fire behaviour prediction and fuel management

Key message We used clustering to construct fuel classes from fuel inventory data based on three stand attributes relevant to crown fire behaviour: surface fuel load (SFL), canopy base height (CBH) and canopy bulk density (CBD). Resulting

Increasing the intensity of regeneration treatments decreased beta diversity of temperate hardwood forest understory 20 years after disturbance

Key message In temperate hardwood forests of Southern Quebec, silvicultural treatments of higher intensities resulted in detrimental effects on soil properties, especially in the surface horizon, 20 years after disturbance. This legacy, in turn, affected the composition

Population history, genetic variation, and conservation status of European white elm (Ulmus laevis Pall.) in Poland

Key message The core populations of the European white elm (Ulmus laevis Pall.) located in Poland maintained slightly higher level of genetic diversity compared to the peripheral populations of this species. Keywords Central-marginal populations; Bottleneck; Microsatellites; DED

Spatial optimization of genetic thinning in seed orchards

Key message We provide a mathematical model to determine which trees should be ruled out from the grid to promote random mating in seed orchards under genetic thinning. Keywords Seed orchards; Spatial layouts; Panmixis; Optimum-Neighborhood Algorithm; Linear
