RECENT ADVANCES ON OAK HEALTH IN EUROPE
22-24 November 1999, Warsaw, Poland
Organised by Forest Research Institute in Warsaw (FRI)
Co-organised with European Forest Institute (EFI)
Oak decline, when it occurs, causes serious economic and ecological perturbations. Because of this, it is important to understand this decline syndrome in order to predict and mitigate its economical effect.
In the last 15 years, the incidence of oak decline has shown a dramatic increase all over Europe; by 1989 it was reported in every European country. Such a situation has prompted many investigations in both Europe and the United States. Up to now, no single universal cause factor (abiotic or biotic) has been found which could explain the widespread abnormal death of oaks. Researchers are agreed that numerous biotic and abiotic causes are involved in the development of the disease.
The increasing number of cases of oak decline in many European countries is causing much concern to both scientists and forest practitioners. The results of the EC-UN/ECE survey showed an abundant occurrence of severely damaged oak trees in Central Europe. The most severe deterioration was observed in Germany, the Czech Republic, Poland and Slovak Republic.
The aims of the conference are to
Interdisciplinary recapitulation of the international research done so far
State of the art of European oak stands health, vitality and the prognosis of oak silviculture in Europe under changing environmental conditions
Exchange of knowledge on implemented forest economic operations in order to overcome oak decline phenomenon problems
Who should attend?
Researchers especially involved in oak health monitoring, forest protection, ecology and silviculture, forest policy makers, managers and politics, forest economists and practitioners.
Chairman: Doc. dr hab. Zbigniew Sierota ? Scientific Director of the Forest Research Institute
Dr. Tomasz Oszako - Phytopathology Section of the Forest Research Institute in Warsaw
Proposed Seminar Programme
Monday, 22 November 1999
Overview of biotic factors involved in European oak decline
Discussion of their importance as both, current or potential damaging factors (locally and globally)
Relationships between the state of the environment, vitality of host oak trees, and their pathogenic organisms
Measures which have to be undertaken in order to diminish the harmful influence of forest pest on oaks
Development of forest pest populations under changing climatic conditions
What is the current trade (in m3) of oak between continents and countries (trade flow ? from where to where?)
What are dangerous pests of oak species and which of them could be potentially transferred from country to country (Ophiostoma kubanicum, O. valachicum, Ceratocystis fagacearum etc.)
What is the potential risk of oak stand damage in different countries (e.g. known from the past)
What should be done to reduce such a risk? Interaction between the amount of oak timber imported to Europe and risk of pest transfer. Cost benefit analysis of such activities
Attempt to estimate the economic value of European oaks (e.g. in ECU, average value of 1 m3 of oak timber)
Attempt to estimate losses (in ECU or %) caused by forest pests or oak decline
Tuesday, 23 November 1999
Estimated and predicted (e.g. due to climate change) total area of oak forests in Europe
Resistance of different species on potential biotic and abiotic damage factors
Resistance of different intra-species forms (e.g. var. praecox and tardiflora, morphological forms of oak, anatomy of particular organs and wood, physiological forms etc.) to potential damaging biotic and abiotic factors
Relationships between oak decline occurrence and distribution of oak provenances in Europe
Potential genetic ways to diminish oak decline risk and discussion on site-effects and maintaining biodiversity
SILVICULTURE AND MANAGEMENT
Influence of improper silviculture and management on oak stands health and resistance to potential damaging biotic and abiotic factors
Relationships between silvicultural methods (clear cuttings, thinnings, artificial plantations etc.) and risk of oak decline (or its acceleration) - case studies
Cultural aspects of landuse (e.g. growing oaks for fuelwood in Mediterranean oak coppice management and its consequences, grazing in oak forests)
Regionally specific aspects of silviculture related to oak decline
Influence of stand site factors (stand composition, stand basal area, stand density, standage, soil richness, etc.) on resistance to potential damage factors (biotic and abiotic)
How could different stand density (stand basal area) influence (increase/inhibit) the development of pest populations (pathogenic fungi, harmful insects, etc.)?
How could different stand density (stand basal area) predispose trees to abiotic damage such as frosts (winter, late spring or early autumn), snow, wind, pollution, etc.
Could silviculture be used as a tool to avoid or mitigate the consequences of oak decline phenomenon in Europe
Attempt to estimate present ecological value of European oak forests. How does the oak decline affect the multiple use of oak forest?
Wednesday, 24 November 1999
Explanation of oak decline phenomenon from physiological point of view (ecophysiological aspects)
Mechanism of tree response to physiological stresses (e.g. draught, frost, high temperature)
Influence of climate change on oak forest growth
Estimated and predicted area of oak forest in Europe (e.g. increase in area due to climate change)
Predictions for oak silviculture in Europe in the face of climate change
Panel session (incl. discussion on the recommendations and possibilities of international and interdisciplinary project settings)
Half a day excursion to the Kampinoski National Park (protection policy, management, health problems, visiting museum followed by barbecue)
People wishing to present a paper or poster should send a one-page abstract (as a Word document with names of authors and affiliation, font Times New Roman 12, single space) by 15 September 1999 to Dr. Tomasz Oszako at Forest Research Institute both as a hard copy and on a diskette or as an email attachment file.
The organisers will select the presentations and posters on the basis of these abstracts and will notify the authors by the 30 September 1999. Abstracts of the accepted papers and posters will be distributed during the meeting The full ? length manuscripts are to be submitted latest by 31 December 1999. Detailed guidelines for preparing and submitting contributions will be sent to authors.
