Climate Change () Spread of forests Soil () Tree composition () Productivity () Risks! resulting from Abiotic and Biotic Stress Influences! Climate Forestry site Position
Climate Change a) steadily progressing process - Temperature: average, heat, frost, length of vegetation period etc. - Precipitation: average, distribution etc. Vegetation period Winter time b) occasionally meteorologic extremes - Storm - Drought and Heat - Flooding Expected scenarios: Unfavorable conditions for trees - higher vulnerability? Favorable conditions for pests - potential for a better development?
Climate Change Shifts of - Interactions between tree species and biotic opponents? - Susceptibility of tree species to biotic damaging factors? Migration? Adaption? Introduction? Keywords: Quarantine Organism, Invasive Species
Concept and approaches - () Assessment of regional current and former biotic risks (retrospective) a. Analysing available data which indicate pest occurrences in Rhineland- Palatinate and Baden-Württemberg (appr., Mio. ha forest area) ( ) - Regular Pest Monitoring - Annual Regular Pest Notices since the 0s - Statistic of unscheduled Incidental Felling due to damages - Records of Consultations - Special Inquiries

Concept and approaches - () Assessment of regional current and former biotic risks (retrospective) a. Analysing available data which indicate pest occurrences in Rhineland- Palatinate and Baden-Württemberg (appr., Mio. ha forest area) - Regular Pest Monitoring - Annual Regular Pest Notices since the 0s - Statistic of unscheduled Incidental Felling due to damages - Records of Consultations - Special Inquiries b. Interpreting available publications, records and other documents c. Survey of the forest protection situation at the relevant investigation areas at the Pfälzerwald, Rhineland-Palatinate d. Correlation (a.-c.) with available meteorological data
Concept and approaches - () Exchange of knowlege and experiences with other federal states and foreign countries () Evaluation of the regional biotic risks integrating the complexity of interactions between different biotic sources of stress and measures by humans () Prognosis of the regional prospective biotic risks at different climate scenarios also using available publications to consider the latest standard of knowledge
Intended Results () Adequate information and data about the current and former biotic damaging factors and the meteorological conditions with respect to the relevant investigation areas at the Pfälzerwald, Rhineland-Palatinate () Qualitative revaluation of the currently known regional risks by pests comparing different tree species with respect to different climate scenarios () Identification and valuation of potentially establishing currently unknown harmful pests comparing different tree species with respect to different climate scenarios () Development of adequate Forest Protection Strategies pointing out the expenses and impacts with respect to different climate scenarios () Recommendations to adjust the Forest Protection Monitoring and Notification System to the requirements induced by aspects of a climate change
Requirements for other groups () Meteorological data (min. daily sum, daily mean) including the parameters rainfall, air temperature, humidity and solar radiation for the period from 0 to 00 for selected monitoring stations (until 00) () Statements about the probability and sequence of extreme meteorologic events like storms, hail or drought stress as important triggers and accelerators for pest calamities (until 00) () Statistical data about the unscheduled Incidental Felling due to damages (MUVF, ZdF Rhineland-Palatinate)(until 00) () ( ) for further requirements see the presentation of Hans Werner Schröck and Joachim Block
