Future research directions:Inclusion of additional data reflecting abiotic ecological factors (climate, surface

geology, soils, etc.)

Analyzing of nonlocal dependencies by the inclusion of non-local measures (e.g., the averages and variances of variables calculated inside moving windows of variable sizes)

Analyzing the distributions of the complex spatial objects by isolating and analyzing image spatial textures

Studying temporal changes (dynamics) by analyzing time series of data

Practical significance:Assistance in conservation planning by delineating areas most suitable for conservation

Finding the most significant carbon storages and sinks in the landscape and their proper management

Revealing areas of significant antropogenic disturbance and the assistance in proper management of the disturbed areas
