The second site was along a newly built road near the post office in Oporów. The aim of the study was to determine whether spatial and technical urbanization in the area has favored the development of a variety of segetal...
Floristic and ecological data was collected three times (in 2000, 2006 and 2011) in fifteen urban parks in Wrocław. Results were compared to determine whether bryophytes can survive in urban environments, or whether they die off because of the constant pressure of urbanization. Other questions examined include whether bryophytes remain in the same habitats, or whether they change their spatial distribution;...

Pilczycki Park, despite of its location in the central part of Wrocław, is characterized...
