The article presents the results of nature monitoring in synanthropic habitats. It shows the organizational aspects of monitoring, a survey procedure, including its assessment for use in synanthropic habitats, and the key findings of the research, including the evaluation of the conservation status of habitats covered by the monitoring and influencing factors’ effects. Observations of segetal and ruderal habitats were carried out in 2013 within the Kampinos National Park, according to the recommendations specified in the State Environmental Monitoring Programme, with specific adjustment to the monitored habitats. We used, for example, modified indices for specific structures and functions, e.g., by introducing the index of “archaeophytes”, which was also adopted as a cardinal index for synanthropic habitats. The obtained results show the detailed information, collected during monitoring, on the current status of synanthropic habitats. They allowed to evaluate conservation status, threats and conservation prospects for these habitats. This is the first proposal for the standardized monitoring of synanthropic habitats in Poland.
Studies aimed at the identification of the range and method of spread of alien plant species in settlement areas in Kampinos National Park (KNP) and its immediate vicinity were carried out in years 2012-2014. Special emphasis was put on surveying the sites of invasive alien species (IAS), and diagnosing potential threats posed to the natural and semi-natural vegetation of the national park by the IAS present in rural areas. We found 53 alien vascular plant species, including 40 invasive taxa which may potentially pose a threat to the ecosystems of KNP. Species encroaching from settlement areas to semi-natural and natural communities included: Bidens frondosa, Echinocystis lobata, Impatiens glandulifera, I. parviflora, Juncus tenuis, Lupinus polyphyllus, Reunoutria japonica and Solidago gigantea. Most of them were species from the highest invasiveness (IV and III) classes in Poland. Similarity analysis carried out for all investigated localities with regard to all alien species, and only for invasive ones showed a clear division into separate groups: villages within the boundaries of the national park and villages outside the park.
