Forests are essential for ensuring the ecological balance and viability of the planet. In today's environment, where we are constantly facing complex environmental challenges, wars, disasters and climate change, the study and conservation of the forest ecosystem is a priority.

This open access book will provide an introduction to forest entomology, the principles and techniques of forest insect pest management, the different forest insect guilds/feeding groups, and relevant forest insect pest management case studies. In addition to covering 30% of the earth, forest ecosystems provide numerous timber and non-timber products that affect our daily lives and recreational opportunities, habitat for diverse animal communities, watershed protection, play critical roles in the water cycle, and mitigate soil erosion and global warming. In addition to being the most abundant organisms in forest ecosystems, insects perform numerous functions in forests, many of which are beneficial and critical to forest health. Conversely, some insects damage and/or kill trees and reduce the capacity of forests to provide desired ecosystem services. The target audience of this book is upper-level undergraduate and graduate students and professionals interested in forest health and entomology.

The SUPERB project aims at large scale forest restoration in Europe, combining scientific and practical knowledge to drive actionable outcomes. In a recent policy brief, some of SUPERB's high-level scientists developed recommendations for changes to the proposed EU Nature Restoration law based on the concepts underpinning our approach to forest restoration. These recommendations prioritize forward-looking restoration strategies by emphasizing ecosystem self-organization and climate change adaptation rather than aiming to restore our forests to past historical states.

Contributions are invited for a special issue of the journal Forests, on the topic of 'Modeling Aboveground Forest Biomass: New Developments'. Forest biomass modelling is crucial to its monitoring and storage. However, biomass in stands and forests varies according to the species, stand structure and site. Biomass models can be developed using data obtained destructive sampling, forest inventory, remote sensing and ancillary. There is a wide range of data science methods and techniques currently applied in order to fit the models and evaluate their uncertainties. Biomass models can be utilized in order to produce management alternatives. This Special Issue aims to offer an overview of the various data sets and modelling methods currently employed to develop biomass functions, as well as their applicability at both the tree and area levels.

This open access book explores a new conceptual framework for the sustainable management of the boreal forest in the face of climate change. The boreal forest is the second-largest terrestrial biome on Earth and covers a 14 million km2 belt, representing about 25% of the Earth’s forest area. Two-thirds of this forest biome is managed and supplies 37% of global wood production. These forests also provide a range of natural resources and ecosystem services essential to humanity. However, climate change is altering species distributions, natural disturbance regimes, and forest ecosystem structure and functioning. Although sustainable management is the main goal across the boreal biome, a novel framework is required to adapt forest strategies and practices to climate change. This collaborative effort draws upon 148 authors in summarizing the sustainable management of these forests and detailing the most recent experimental and observational results collected from across the boreal biome. It presents the state of sustainable management in boreal forests and highlights the critical importance of this biome in a context of global change because of these forests' key role in a range of natural processes, including carbon sequestration, nutrient cycling, and the maintaining of biodiversity. This book is an essential read for academics, students, and practitioners involved in boreal forest management. It outlines the challenges facing sustainable boreal forest management within the context of climate change and serves as a basis for establishing new research avenues, identifying future research trends, and developing climate-adapted forest management plans.

Responding to Environmental Issues Through Adaptive Collaborative Management: From Forest Communities to Global Actors has just come out (2023) and is open access. Co-edited by anthropologist Carol J. Pierce Colfer and forester Ravi Prabhu, it compiles the writings of a total of 45 authors, most of whom hail from developing countries. It is the second in a series – the other being Adaptive Collaborative Management of Forest Landscapes: Villagers, Bureaucrats and Civil Society (2022, also open access, see below). The genesis of these books involved a query to those partners who had participated in ACM's early days (2000s). What had they learned about ACM in the two intervening decades?

This second book, which focuses on three islands in Indonesia (Sumatra, Sulawesi and Java) and five countries in sub-Saharan Africa (Cameroon, Kenya, Malawi, Uganda and Zimbabwe), includes three revisits to former ACM research sites from the early 2000s to assess what has endured and what has fallen away; new methods that build on the ACM approach; a thought experiment on how to scale up more effectively; and some ideas on how to support and encourage a 'culture of care', in our efforts to address environmental issues and those of the human beings who inhabit forested areas particularly.

Many forest management proposals are based on top-down strategies, such as the Million Tree Initiatives, Forest Landscape Restoration (FLR) and REDD+, often neglecting local communities. In the context of the climate crisis, it is imperative that local peoples and communities are an integral part of all decisions relating to resource management. This volume examines the value of Adaptive Collaborative Management for facilitating learning and collaboration with local communities and beyond, utilising detailed studies of forest landscapes and communities.

This report presents the overall situation and main recent achievements in the Ukrainian forest sector before the war and provides a general overview of the current situation including major war consequences for the sector and the environment in Ukraine. It shows the difficulties to be expected for the recovery process of the Ukrainian forest sector. The report has been prepared by the Liaison Unit Bonn of Forest Europe and will be presented for information and further discussion at the first workshop of the newly established FOREST EUROPE Ukraine support.

A growing number of businesses advertise their tree planting engagements even though it is generally outside their core business. Why do they do it? Where do they do it? With whom do they do it? How pervasive is this phenomenon? These are questions a new study seeks to answer for three European countries: France, Switzerland and the United Kingdom. The authors of the study selected all large corporations from those countries present on the Fortune 500 list of companies and analysed their reports and available documentation to see firstly whether they were engaged in tree planting and if yes, to answer the above questions. The findings indicate that in the last 22 years, 98% of the large corporations from the three countries reviewed have carried out some tree planting activities, contributing to planting well over 500 million trees.
