Sažetak
With the rapid development and expansion of urban areas and the increasing share of the population living in urban areas, the preservation and protection of green areas becomes more and more important. Zagreb is one of the few European metropolis that has preserved natural forests incorporated into urban tissue of the city. Forests in cities are of great significance for the quality of life in a society that is intensively urbanized. Maksimir is the most famous and most visited Zagreb forest park, and a well-used recreational space embedded in the urban area, and also an ecological base that provides general welfare. From the period of proclamation of the forest park, there have been many changes so far, but this is still a unique set of natural forest stands. Due to changes in the environment and age, the health status of the trees is impaired. In order to better monitor this situation, it is necessary to carry out the inventory of the damage. This has been largely terrestrial observations so far, and today remote sensing methods are increasingly being used. The work on the WorldView 2 satellite will be used to interpret the health status of individual trees on a systematic sample. Based on the results of the interpretation, the indicators of damage for each tree species and total for the entire recorded area of the forest park Maksimir will be calculated and the thematic maps of the spatial distribution of damage will be created. By comparing the results of satellite imagery WV2 and satellite images taken from Google Earth, a change in the health status of trees has been observed, which confirms how satellite imagery can serve to inventory and track the state in some space over a number of years. The field investigation and assessment of the health status of trees confirmed the results obtained by interpretation of satellite images, but also confirmed that based on the recordings we can foresee the future stand of the stands. Since quality forest monitoring is based on a systematic collection of forest data in some areas and at some point in time, the resulting results represent the current state of health and are the basis for monitoring and predicting the future status. In urban environments, it is particularly important that the health status changes of trees are timely predicted so that the sick trees can be removed and replaced by new ones.
