This article examines the use of mobile Geographic Information Systems (GIS), particularly the Flora Incognita application, for documenting vegetation along the green ecological trail in the Barlinek Landscape Park. The study evaluates the usability of the application, the accuracy of plant identification, and its potential to generate high-quality georeferenced data. The results indicate that Flora Incognita is an efficient and cost-effective tool for rapid floristic surveys, achieving high identification accuracy which, when complemented by expert verification, can significantly enhance monitoring efforts. The analysis demonstrates how citizen-generated data can be utilized to develop dynamic spatial databases, supporting park management in tasks such as mapping invasive species and tracking phenological changes. The article concludes that, although mobile GIS applications cannot replace traditional scientific methods, they represent a complementary approach that promotes public engagement and contributes to a more comprehensive understanding of local and macroecological patterns.
