We address the problem of how to integrate risk assessment into forest management and therefore provide a comprehensive review of recent and past literature on risk analysis and modeling and, moreover, an evaluation and summary on these papers. We provide a general scheme on how to integrate concepts of risk into forest management decisions. After an overview of the risk management process and the main hazards in forests (storm, snow, insects, fire), the paper focuses on the principal methods used to assess risks from these hazards for commercial forestry. We review mechanistic models, empirical models, and expert systems and consider the needs for different spatial scales of risk assessment, from the regional to the single-tree level. In addition to natural hazards and their secondary effects, we deal with economic aspects of risk analysis. Monte Carlo simulations to deal with volatile timber prices and ways to include risk in classical Faustmann approaches are briefly discussed along with the integration of portfolio theory into forest management decision making and attitude toward risk. Special attention is paid to the implications for risk modeling under climate change.

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Fagus sylvatica imported from the United Kingdom (UK) as: (a) 1‐ to 7‐year‐old bare root plants for planting, (b) < 1‐ to 15‐year‐old plants in pots and (c) bundles of 1‐ to 2‐year‐old whips and seedlings, taking into account the available scientific information, including the technical information provided by the UK. All pests associated with the commodity were evaluated against specific criteria for their relevance for this opinion. Two EU quarantine pests, Phytophthora ramorum (non‐EU isolates) and Thaumetopoea processionea, and two pests not regulated in the EU, Meloidogyne mali and Phytophthora kernoviae, fulfilled all relevant criteria and were selected for further evaluation. For the selected pests, the risk mitigation measures implemented in the technical dossier from the UK were evaluated taking into account the possible limiting factors. For these pests an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. In the assessment of risk, the age of the plants was considered, reasoning that older trees are more likely to be infested mainly due to longer exposure time and larger size. The degree of pest freedom varies among the pests evaluated, with M. mali being the pest most frequently expected on the imported plants. The expert knowledge elicitation (EKE) indicated with 95% certainty that between 9,793 and 10,000 plants in pots up to 15 years old per 10,000 will be free from M. mali.

The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as 'Highrisk plants, plant products and other objects'. This Scientific Opinion covers plant health risks posed by plants of Quercus robur imported from the UK as: (a) bundles of 1-to 2-year-old whips and seedlings, (b) 1-to 7-year-old bare root plants for planting and (c) less than 1-to 15-year-old plants in pots, taking into account the available scientific information, including the technical information provided by the UK. All pests associated with the commodity were evaluated against specific criteria for their relevance for this opinion. Two EU quarantine pests, Cronartium quercuum and Phytophthora ramorum (non-EU isolates), two protected zone quarantine pests, Cryphonectria parasitica and Thaumetopoea processionea and four pests not regulated in the EU, Coniella castaneicola, Meloidogyne mali, Phytophthora kernoviae and Trinophylum cribratum, fulfilled all relevant criteria and were selected for further evaluation. For the selected pests, the risk mitigation measures included in the technical dossier from the UK were evaluated taking into account the possible limiting factors. For these pests an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. In the assessment of risk, the age of the plants was considered, reasoning that older trees are more likely to be infested mainly due to longer exposure time and larger size. The degree of pest freedom varies among the pests evaluated, with C. castaneicola being the pest most frequently expected on the imported plants. The expert knowledge elicitation indicated with 95% certainty that between 9,711 and 10,000 per 10,000 less than 1-to 15-year-old plants in pots will be free from C. castaneicola.
