The threats posed by air pollution and climate change have resulted in considerable public debate about forest condition and growth during the past two decades. Despite the massive input ofresearch resources, no clear answers have been found to these global questions. Although there have been substantial advances in our knowledge of the effects of air pollutants on the forests, many of the questions associated with forest condition are still open. Monitoring of forest condition at the national level started in Finland in 1985 in accordance with the methodology drawn up by the International Co-operative Programme on Assessments and Monitoring of Air Pollution Effects on Forests (ICP Forests, UN/ECE). Since then, research into forest condition and vitality has been one of the key areas in the research carried out by the Finnish Forest Research Institute. Three basic questions formed the starting point for the multidisciplinary, Forest Condition Research Programme: What changes are taking place in our forests? Why does forest condition vary, and why do trees appear to be suffering? How can forest condition be maintained through appropriate forest management? This report covers forest condition and changes in environmental factors on the of the latest findings, publications and expertise of researchers participated in basis the Forest Condition Research Programme. In addition to researchers from the Finnish Forest Research Institute, a large number of scientists from domestic and foreign universities and research institutes also made a considerable contribution to the research programme.

Mount Elgon is a transboundary East African montane ecosystem that harbors unique biological diversity and provides critical goods and services to the surrounding densely populated communities. As a key water tower, the effectiveness of forest- and land-management policies has direct impacts on agriculture, hydropower, fisheries and other sectors across large watersheds in Uganda and Kenya (and onward to the whole Nile River basin). The Uganda Wildlife Authority (UWA), the Kenya Wildlife Service (KWS) and the Kenya Forest Service (KFS) have developed a range of exclusionary protected area and partial-access participatory forest management approaches to enforce national conservation mandates in different portions of the Mount Elgon. The future resilience of forest assemblages will be challenged as climate change and increased variability in weather patterns interact that with societal interventions that may enable the introduction of exotic species, the expansion of diseases. The objective of this study was to assess the impact of different forest governance regimes on forest structure and composition over time (1997-2014). Two study sites in Uganda (Kapkwai and Bufuma) and Kenya (Chorlem and Kimothon) under differing forest governance arrangements were monitored from 1997 to 2014 using the International Forestry Resources and Institutions (IFRI) methodology. Each forest unit was sampled three to four times (1997, 2001/2, 2008, 2013/14), at 30 randomly established sample plots. Data was collected on seedlings (counts), saplings and shrubs (diameter at breast height [DBH] and height), trees (DBH and height) and forest use. This analysis of forest structure and composition included density, basal area, dominant species, species richness and the Shannon-Wiener species diversity index. When comparing the outcomes for participatory forest management and centralized forest management in Uganda versus Kenya, the results defy dogmatic generalizations as the outcomes differed in the two countries. Furthermore, this study highlighted the fragility of certain improvements in forest resilience. In this respect, recent declines in forest cover mean that these forest management regimes will need to continue improving their engagement with local communities in order to address both internal socioeconomic and urban-/private sector-driven deterioration of Mount Elgon's forests. This study also highlights the need for greater integration of development (climate-change adaptation) and conservation (climate-change mitigation) policies.

Forests cover 30% of the Earth’s land area, or nearly four billion hectares. Enhancing the benefits and ecosystem services of forests has been increasingly recognized as an essential part of nature-based solutions for solving many emerging global environmental problems today. A core science supporting forest management is understanding the interactions of forests, water, and people. These interactions have become increasingly complex under climate change and its associated impacts, such as the increases in the intensity and frequency of drought and floods, increasing population and deforestation, and a rise in global demands for multiple ecosystem services including clean water supply and carbon sequestration. Forest watershed managers have recognized that water management is an essential component of forest management. Global environmental change is posing more challenges for managing forests and water toward sustainable development. New science on forest and water is critically needed across the globe. The International Forests and Water Conference 2018, Valdivia, Chile (http://forestsandwater2018.cl/), a joint effort of the 5th IUFRO International Conference on Forests and Water in a Changing Environment and the Second Latin American Conference on Forests and Water provided a unique forum to examine forest and water issues in Latin America under a global context. This book represents a collection of some of the peer-reviewed papers presented at the conference that were published in a Special Issue of Forests.

In conclusion, current-year, first-flush foliage of branches grown in 525 , . . d 1- 1 and 700 J. . Lll-I of carbon dioxide had much greater rates of Pm ax compared to the P max of foliage grown in 350 J. . Lll- I carbon dioxide. These findings are similar to other long-term field studies with loblolly pine (Teskey, 1995; Murthy, 1995). Elevated carbon dioxide concentration was also significantly affected the G , max however, higher rates were only found at the 525 J. . Ll 1-I carbon dioxide con centration. Generally the total chlorophyll content decreased as the carbon dioxide concentration was increased. The data presented here represent first-year responses to the carbon dioxide and cultural treatments. This experiment will continue to determine whether increased maximum net photosynthetic rate resulting from elevated carbon dioxide will persist over the life of the foliage and over an anticipated greater range of moisture and nutrient availability than existed during the first year of the study. In addition to this determination, evidence will also be collected to test for the possibility of downward acclimation of photosynthesis by foliage exposed to long-term ele vated carbon dioxide concentrations. Detailed phenology measurements of branches and whole trees are expected to further the knowledge of how loblolly pine trees growing at the edge of the natural range respond to variations in carbon dioxide concentration, water, and nutrient supply.

After the successful conclusion of the Joint Meeting of IUFRO’s 7.03.05 & 7.03.10 working parties and given the exciting and novel studies that have been presented in the framework of this meeting, we decided to present some of these studies in the current Special Issue of Forests. To make this issue more appealing and interesting to everyone in the field of Forest Protection, studies that cover a wide range of topics were selected, ranging from ecology and phylogeography to forest management and protection. More importantly, as these studies refer to pests and pathogens from different parts of the world, it is expected that the knowledge gained can be further used in the protection of natural environment worldwide.

The effects of air pollution on biota may be subtle and elusive because of their interactions with natural stresses. Studies based on a network of sites in the Carpathian Mountains form the core of the content presented during this workshop. To this core are added key components on ecological sustainability, overviews on forest health in Europe and the world and several in-depth case studies.
