Investigations regarding the effect of the deposition of pollutants, drought, nutrition and ozone on spruce sickness at the Wank montain in the Calcareous Alps; Untersuchungen zur Wirkung von Stoffeintraegen, Trockenheit, Ernaehrung und Ozon auf die Fichtenerkrankung am Wank in den Kalkalpen

Abstract

This is the final report on the project ``Water, nitrogen and phosphorus availability in soil: Stress factors for spruces at the Wank mountain?`` The investigations were conducted during the period from July 1, 1991 to June 30, 1994 and built on a preceding project started in 1985 because of alarming damage in spruces in this site. Apart from pedological aspects, plant-physiological aspects needed to be taken into account, which are influenced by soil, climate and air-chemical factors. Spruce damage at the Wank is to be understood as the result of a complex interaction of natural and man-made effects, which are more visible here because of the unfavourable site conditions due to the labile mountain ecosystem at the Wank. Most important is deficiency in the nutrients phosphorus and nitrogen, owing, probably, originally to human activities in the form of litter utilization and the use of forests as pasture. Their latent threat to spruces is brought to bear particularly by periods of drought. A second pathway of action are high ozone concentrations in summer, also favoured by climatic conditions, which result in heavier loss of green needles. (orig.)

[Deutsch] Bei der vorliegenden Arbeit handelt es sich um den Abschlussbericht zum Projekt `Wasser-, Stickstoff- und Phosphorverfuegbarkeit im Boden: Stressfaktoren fuer Fichten am Wank?` Die Untersuchungen wurden im Zeitraum vom 0.1.07.1991 bis 30.06.1994 durchgefuehrt und bauen auf ein vorgausgegangenes Projekt auf, das 1985 aufgrund alarmierender Fichtenschaeden auf dem Standort gestartet wurde. Neben bodenkundlichen Gesichtspunkten waren pfanzenphysiologische Aspekte einzubeziehen, welche durch Boden, Klima und luftchemische Faktoren beeinflusst werden. Die Fichtenschaeden am Wank sind als Resultat eines komplexen Zusammenspiels natuerlicher und anthropogener Wechselwirkungen zu verstehen, welche aufgrund der unguenstigen Standortbedingungen des labilen Gebirgsoekosystems am Wank besonders deutlich sichtbar werden. Im Vordergrund stehen Naehrstoffmaengel hinsichtlich Phosphor und Stickstoff, welche vermutlich durch Streunutzung und Waldweide urspruenglich anthropogen augeloest sind. Ihre latente Bedrohung fuer die Fichten kommt durch klimatisch bedingte Trockenperioden verstaerkt zur Wirkung. Als zweiter Wirkungspfad ist eine ebenfalls klimatisch beguenstigte sommerliche Ozonbelastung festzustellen, welche einen verstaerkten Abwurf gruender Fichtennadeln zur Folge hat. (orig.)}
