Remote sensing of the succession of agricultural land in the area of Müllerov brijeg

Müllerov brijeg covers an area of 28 ha and is located in the municipality of Črnomerec in the city of Zagreb. Before the First World War, it was owned by a Jewish industrialist family, when it was used as a modern orchard and vineyard. Mainly apples, pears and peaches were grown there with an intercrop of strawberries. Modern American and European varieties were represented, propagated mainly on a vegetative basis, rational planting intervals and cropping patterns with the application of modern soil protection and maintenance measures. After the 1970s, when a suburban population increased significantly, the area was used for smaller plots of vegetable production. In recent decades, agricultural use was abandoned due to a change in ownership, which led to successive changes in vegetation cover and healing. Therefore, the objective was to map and digitize the area by remote sensing using archival and current orthophotos from 1968, 2011 and 2020 in QGIS 3.10.8. The greatest change occurred in the decrease of areas under orchards that have completely disappeared in the past 52 years, confirming the research hypothesis. Macchia areas also considerably increased in 2020 compared to 1968, due to lack of maintenance and neglect of agricultural fruit production. A total of 109 taxa were identified, mostly ruderal and eight invasive plant taxa.
