Abstract. Extreme events are widely studied across the world because of their major implications for many aspects of society and especially floods. These events are generally studied in term of precipitation or temperature extreme indices that are often not adapted for regions affected by floods caused by snowmelt. Rain on Snow index has been widely used but it neglects rain only events which are expected to be more frequent in the future. In this study we identified a new winter compound index and assessed how large-scale atmospheric circulation controls the past and future evolution of these events in the Great Lakes region. The future evolution of this index was projected using temperature and precipitation from the Canadian Regional Climate Model Large Ensemble (CRCM5-LE). These climate data were used as input in PRMS hydrological model to simulate the future evolution of high flows in three watersheds in Southern Ontario. We also used five recurrent large-scale atmospheric circulation patterns in northeastern North America and identified how they control the past and future variability of the newly created index and high flows. The results show that daily precipitation higher than 10 mm and temperature higher than 5 °C were a necessary historical condition to produce high flows in these three watersheds. In the historical period, the occurrences of these heavy rain and warm events as well as high flows were associated to two main patterns characterized by high Z500 anomalies centred on eastern Great Lakes (HP) and the Atlantic Ocean (South). These hydrometeorological extreme events will be more frequent in the near future and will still be associated to the same atmospheric patterns. The future evolution of the index will be modulated by the internal variability of the climate system as higher Z500 in the east coast will amplify the increase in the number of events, especially the warm events. The relationship between the extreme weather index and high flows will be modified in the future as the snowpack reduces and rain becomes the main component of high flows generation. This study shows the values of CRCM5-LE dataset to simulate hydrometeorological extreme events in Eastern Canada and to better understand the uncertainties associated to internal variability of climate.

The Future

The development of the forester's leadership role in forest land management is compared to rising profile of land between a sea or lake shoreline and a range of mountains, the progression is upward but the rate of climb changes. No plateau is identified. Reference is made to forestry leadership in several fields of forest land management; administration, land use, planning, research, forest management, recreational land use and fish and wildlife management. It is noted that forest land management includes activities for which foresters were not academically trained and reference is made to the fact that non-foresters, e.g. biologists and geographers are giving leadership in forest land management and thus providing beneficial competition and stimulation. The most important leadership role in the future may relate to regional planning. The forestry profession is cautioned not to abdicate this field to those in other disciplines.

The Future

The traditional method of predicting future yields of conventional forest products and/or biomass is based on an empirical bioassay of the growth potential of unmanaged stands, or of stands subject to one, or a small number of, management practices. The method employs the historical pattern of stem volume and/or forest biomass accumulation in the form of volume- or biomass-over-age curves. This type of yield predictor, which may be presented as a simple yield table or a more complex mensurational computer yield model, is widely considered to produce believable future yield predictions. However, the predictions will only be accurate if the future environmental conditions and management regimes are similar to those that pertained over the period during which the biomass accumulation on which the yield model is based occurred. This is unlikely because the continued growth of the human population and the resultant loss of forest land will require a great intensification of forest management. The significant changes in management that many believe await forestry in the not-too-distant future in many parts of the world will render such conventional predictions very questionable. In addition, human-induced changes in atmospheric chemistry may result in changes in the climatic (the "green-house gases" problem), canopy or soil conditions (the "acid rain" problem) that determine tree growth.Computer models of forest yield based solely on the simulation of the biological processes that determine tree growth do not at present offer a viable alternative. Either we do not yet know enough to build, or we do not have sufficient resources to develop and calibrate such process models at an adequate level of complexity.What is needed is a generation of hybrid yield models that combine traditional mensurational models with a simulation of those growth-regulating processes that are significantly altered by changing management practices and/or by changing atmospheric chemistry and climate. One such model is FORCYTE: the FORest nutrient Cycling and Yield Trend Evaluator. This is an ecologically-based forest management simulation model that can predict the long-term consequences of a wide variety of forest management practices for the future harvest yield, ecosystem nutrient budgets, economic efficiency and the energy benefit/cost ratio of management. It combines the believability of the traditional approach with the flexibility of ecological and biological process simulation. Present versions of the model focus on the consequences for future production and yield of changes in forest management. However, because of the structure of the model, it is capable of being modified to examine similar consequences of climatic change and alteration in atmospheric chemistry. Progress in the latter area must await clarification of the processes involved in acid rain damage to forests. FORCYTE is also capable, with minor modification, of being used in agriculture and mined land reclamation research and planning. Key words: Yield prediction, FORCYTE.

Abstract. Extreme events are widely studied across the world because of their major implications for many aspects of society and especially floods. These events are generally studied in terms of precipitation or temperature extreme indices that are often not adapted for regions affected by floods caused by snowmelt. The rain on snow index has been widely used, but it neglects rain-only events which are expected to be more frequent in the future. In this study, we identified a new winter compound index and assessed how large-scale atmospheric circulation controls the past and future evolution of these events in the Great Lakes region. The future evolution of this index was projected using temperature and precipitation from the Canadian Regional Climate Model large ensemble (CRCM5-LE). These climate data were used as input in Precipitation Runoff Modelling System (PRMS) hydrological model to simulate the future evolution of high flows in three watersheds in southern Ontario. We also used five recurrent large-scale atmospheric circulation patterns in north-eastern North America and identified how they control the past and future variability of the newly created index and high flows. The results show that daily precipitation higher than 10 mm and temperature higher than 5 ∘C were necessary historical conditions to produce high flows in these three watersheds. In the historical period, the occurrences of these heavy rain and warm events as well as high flows were associated with two main patterns characterized by high Z500 anomalies centred on eastern Great Lakes (HP regime) and the Atlantic Ocean (South regime). These hydrometeorological extreme events will still be associated with the same atmospheric patterns in the near future. The future evolution of the index will be modulated by the internal variability of the climate system, as higher Z500 on the east coast will amplify the increase in the number of events, especially the warm events. The relationship between the extreme weather index and high flows will be modified in the future as the snowpack reduces and rain becomes the main component of high-flow generation. This study shows the value of the CRCM5-LE dataset in simulating hydrometeorological extreme events in eastern Canada and better understanding the uncertainties associated with internal variability of climate.

Forest and forest management in Canton Zurich – surprisingly varied! The forest in Canton Zurich is surprisingly diversified. The demands made upon it are just as varied. In particular forests near towns combine the functions of protection, productivity and welfare. More than half the forest land is in private ownership. In these circumstances it is not easy to fulfil all functions of the forest, whilst ensuring its sustainable management and use. In order to do this, Canton Zurich uses two instruments: a locally based forestry service present on the terrain, and a solid forestry planning at various levels. The reinforcement and continuation of these institutions are decisive in order to maintain the forest as a habitat, an economic and a recreation area. Only a far-sighted treatment of our forests, an intensive dialogue between forest owners and those who benefit from the forest, and the negotiation of workable compromises can guarantee that we may profit from forest products and services in the future.

The Impact

<p>In the spring of 2020, as the coronavirus swept across the globe, millions of people were required to make drastic changes to their lives to help contain the impact of the virus. Among those changes, scientific conferences of every type and size were forced to cancel or postpone in order to protect public health. Included in these was the European Geosciences Union (EGU) 2020 General Assembly. After a six-week pivot to an online alternative, attendees of the newly designed EGU20: Sharing Geoscience Online took part in the first geoscience conference of its size to go fully online.<br> <br>This work explores the feedback provided by participants following this experimental conference and identifies four key themes that emerged from analysis of the questions: what did people miss from a regular meeting; and to what extent did going online impact the event itself, both in terms of challenges and opportunities?<br> <br>The themes identified are: connection, engagement, environment, and accessibility; and include discussions of the value of informal connections and spontaneous scientific discovery during conferences, the necessity of considering the environmental cost of in-person meetings, and the opportunities for widening participation in science by investing in accessibility.<br> <br>The responses in these themes cover both positive and negative experiences of participants and raise important questions about what conference providers of the future will need to do to meet the needs of the scientific community in the years following the coronavirus outbreak.</p>

With GIS technology now about 25 years old, it is appropriate to consider where GIS use may be leading us, with special reference to natural resource management uses and considering forest management in particular. After beginning with a consideration of where GIS technology is going, and with mention of several important related technologies, the paper considers the range of problems and of possible immediate futures for natural resource management generally, and for forest management in particular. The role of GIS in natural resource management is taken up next. Some comments on who determines where GIS technology will go in the future are offered. The paper concludes with a consideration of where GIS technology may lead natural resource management in the next decade and just after the turn of the century.
