Abstract

The study was focused on a common acacia forestry ecosystem. Two types of measurements were performed: the tree stem diameter and the tree ring growth. Auto-correlation function, correlation dimension, Lyapunov exponent, fast Fourier transform and the wavelet transform indicated chaotic trends in the studied ecosystem. Smoothing raw spatial data determined significant modifications especially at the level of the correlation dimension, indicating that an important source of noise was activated when the spatial mono-dimensional data series was constructed. In both data series the degree of complexity is rather high, a chaotic behavioral trend overlapping the quasi-periodical main pattern in the studied forestry ecosystem
