Intraspecies diversity of sessile oak in the Thaya valley and use as a resource for forestry practice - subproject: drought tolerance- carbon isotope signature
Abstract
In northeastern Austria, a regions particularly affected by drought, we face a shortage of suitable seeds and seedlings of deciduous tree species. As part of the project "Thayatal oaks - forest genetic resources for the future" (TERZ; funded by the federal government, the states and the European Union), sessile oak tree stands will be established, which can be used in the long term as seed harvest stands (de novo). For this purpose drought-tolerant individual trees in the Thayatal, in particular in the area of the national park, are characterized using various methods (dendrology, morphology, water use efficiency, drought tolerance genes). Seedlings are grown from the seeds harvested and finally planted in the Waldviertel as future seed sources for forestry practice. We expect that particularly in the Thayatal National Park drought-tolerant sessile oaks can be identified. In addition to the long-term provision of drought-tolerant oak seeds in this project, the biodiversity of the national park can also be protected by a known intraspecies (= genetic) component. This would create the basis for genetic monitoring of the national park, which the national park management could carry out in the future with its own staff. This project supports both forestry and nature conservation in this region. The BOKU supports the Austrian Research Centere for Forests (BFW) to characterise the selected individual trees with regard to drought tolerance, among other methodologies with the help of carbon stable isotope analyses in tree rings from dry and wet years.
