Project description:
Previous monitoring procedures in the field of forest protection are of limited suitability for assessing specific forest stands regarding their potential risk of being damaged by various abiotic and biotic stressors based on their current status. With regard to the progressing climate change and forest conversion taking place, it is necessary to develop innovative technologies to detect local stressors in time. Ion-mobility spectrometry (IMS) facilitates a sensitive, continuous detection of odour patterns and is suitable for the use in the field. Proving the presence of insect pheromones with IMS, for instance, allows for a quick and cost saving way of proving the presence of pest organisms.
Within the subproject, the parameters required on interactions between forest structures and potential damaging factors are compiled to be provided to other project partners for modelling the occurrence and distribution of potential damaging factors. Furthermore, the odour patterns to be used for IMS are being defined, and scenarios and experimental designs for testing the suitability of IMS are developed and carried out. Our goal is to detect pheromones released by insects in the forest, rather than to use artificial pheromones in traps to detect the infestation.
The analysis of interactions between forest structures and damaging factors comprises all currently important leaf- and needle-eating moths, sawflies, bark and jewel beetles on Scots pine, European spruce, common oak, sessile oak and European beech as well as forest fires. European spruce bark beetle (Ips typographus), nun moth (Lymantria monacha), and oak processionary moth (Thaumatopoea prozessionea) will be used as examples for IMS.
Using the IMS data to develop an automatic and online risk analysis for potential biotic and abiotic damaging factors on a forest stand level enables the design of a modern and effective monitoring procedure. Risk scenarios for varying forest management strategies provide the possiblity to derive recommendations for actions for the current management.
As a result, currently existing monitoring systems that are expensive and provide limited information can be replaced, and users are given a wider range of application options in the field of risk prevention.
