We are always happy to have “guest-authors” who give us an insight into their work. Carrie Ewing, PhD Student at The Ohio State University, is currently researching tree genetics to determine the plant pathogen(s) that are causing beech leaf disease (BLD), a new and seemingly lethal disease affecting American beech trees (Fagus grandifolia).
The disease was first discovered in forests
in the northeastern United States and parts of Canada. John Pogacnik, a
biologist at Lake Metroparks in Ohio, first observed BLD in 2012 in northeast
Ohio, U.S.A. The disease has been spreading
rapidly and has now affected forests in Ohio, Pennsylvania, New York State, and
This year the International Day of Forests (IDF) will address the exciting theme “Forests and Education”. It is an occasion to raise awareness, to inform and to educate a broad public, different stakeholders and forest-managers about forest-related topics.
Forests cover one third of land on Earth, and they perform crucial and vital functions around the world. Trees improve our lives both at a grand scale and at the local level. Despite those benefits, deforestation and consequences of climate change are among other great challenges for forests.
Urban environmental challenges require on-site environmental solutions. As such, green infrastructure is
widely proposed as a feasible measure towards the resilience and sustainable
development of urban areas.
Urban forests represent the back-bone of urban
green infrastructure by connecting the rural and city interface, and they
provide both environmental and social benefits given that an adequate
implementation and management is in place. However, all efforts may fail if
there are not consistent and universal tools to quantify and characterize the necessary
factors involved in the practice, policy and decision-making process. That is
why we should consider the potentials of integrating urban forests within the
National Forest Inventory.

Two major storms, Eberhard
and Franz, hit Germany and so its most populous state,
North Rhine-Westphalia, last week. Experts are still assessing the full extent
of the damage, but what is clear: this huge damage will have long-term impacts
on forests. It also demonstrates once again the extent of enormous damages that
are caused by storms and the related secondary damages like bark beetle infestation.
Voices of Resilience introduces Rupert Seidl, Professor of forest ecosystem management and Deputy Head of the Institute of Silviculture at the University of Natural Resources and Life Sciences (BOKU), Vienna, Austria. His research focuses on understanding how climate and disturbances affect forest ecosystem dynamics, and on applying this knowledge towards increasing the robustness of forest management in a changing world.
Die Einführung von Baumarten ist ein bedeutendes und zugleich kontroverses Thema. In allen Ländern Europas sind eingeführte Arten einerseits als Chance für die Steigerung der Holzproduktion gesehen und können Alternativen für eine sich unter dem Einfluss des Klimawandels verändernde Artenzusammensetzung in Wäldern darstellen. Andererseits können eingeführte Arten auch die Ursache für den Verlust an Artenvielfalt sein, natürliche Ökosysteme stören und bei ungewünschter Verbreitung hohe Kosten verursachen.
The European Commission recently published a report entitled: Forest Fires, Sparking firesmart policies in the EU.
Forest fires constitute a serious and increasing threat throughout Europe, particularly in Greece, Spain, France, Italy and Portugal. Currently we are also observing more and more fires in the temperate zone of Central Europe. Despite a decreasing trend in the number of fires and areas burned, observed in some countries since the 1980s, larger and more damaging fires (i.e. ‘megafires’) are challenging the suppression capacities of many wildfire protection programmes across Europe.
