There is a problem that the protected areas do not have the basic cartographic material of high detail, and the cartographic material reflecting the actual state of the territory, there is also no cartography and actual information about the status of other areas important for the protection of specific species and natural communities. To compensate for this gap, we began work on surveying areas of environmental importance using unmanned aerial vehicles (UAVs).
As a result of filming, we get a photo-plan of high-resolution terrain and a digital relief model, perspective photographs of the terrain and video-plots.

Shooting areas with the help of the UAV, allows assessment of the colonies of birds nesting in the wetlands. On the example of a great white egret (Ardea alba L.1758) – species of fauna which are subject to strict protection in accordance with Annex II of the Convention on the Conservation of Wild Flora and Fauna and Natural Habitats in Europe (Bern, 19.09.1979).

In addition, we plan to conduct periodic surveys of some areas to monitor the state of natural objects for a long time.
At the moment we are shooting mainly with cameras taking pictures in the visible spectrum, but we hope that in the near future we will have a camera that allows us to shoot in the infrared spectrum. This will allow for a more detailed study of plant communities through vegetative indices, to study the vegetative activity of various herbaceous ecosystems, the state of forest tracts and much more.
Also, for a better survey of the terrain and accurate positioning of the resulting photographic plans and digital terrain models, we use a geodetic GPS receivers with RTK corrections.
