Forest development under varying herbivore pressure
Interspecific competition among the red deer, roe deer and chamois
Abstract:
The project is separated into two closley associated projects.
Project 1: Landscape modelling by Dr. Peter J. Weisberg
The overall goal of this part of the project is to providea coupled landscape-scale model of forest development under varying herbivore pressure that can be used in a predictive mode as well as for
scenario calculations to assist the planning of future forest and game management regines. Specific questions to be addressed are:
1.What are the effects of ungulate herbivory on forest tree regeneration, and on longterm forest dynamics, in the Swiss Alps?
At current and varying population levels
Under current and changing climate
2.How can forest management mitigate the effects of ungulate herbivory such that forest regeneration targets might be achieved?
Silvicultural manipulation
Management of the ungulate populations
Project 2: The influence of ungulate competition on diet selection, habitat selection, and browsing intensity in mountain forests by Ludger Wenzelides
The overall aim of this study is to investigate the effects of interspecific competition among the red deer, roe deer and chamois on the quantity and quality of herbivory. Specifically, this thesis will
focus on the following issues:
1.Characterization of available ungulate habitat in a mountainous region of Switzerland (Toggenburg).
2.Collecting data on ungulate population densities and diet composition as well as gathering information about browsing intensity all at the same spot.
3.Inferring the degree of competition between the animals by using the niche overlap built upon a habitat suitability model which will incorporate the vegetation data and the population
densities of the three animal species.
4.Relating the data from the competition indices with the results of browsing intensity
5.Developing a statistical habitat suitability model for the ungulate species, which is then used as a module in the HUNGER model of forest dynamics model (sub-project by Peter
Weisberg).
