If a Quickscan identifies the presence of suitable structures or habitats for protected species, species-specific research is required. These surveys are carried out according to established protocols (e.g., the Dutch Bat Protocol and BIJ12 guidelines) to ensure accuracy and reliability. The research determines whether protected species are actually present in your project area and whether your planned activities could negatively affect them or their habitat.
The research involves several field visits: we examine the project area and its immediate surroundings multiple times during the active season of the species in question, looking for signs of their presence. Bats, swifts, and sparrows may roost or nest in cavities, under roof tiles, or within walls. Because surveys must take place over the span of the specific activity periods, the process is time-demanding and may affect the overall project timeline if not planned in advance.
Active survey periods:
- Bats – April to July and August to October
- Swifts – May to July
- House sparrows – April to mid-May
After the research, you will know:
- Whether protected species are present and if an exemption is required
- The ecological role of the project area
- What mitigation or compensation measures are necessary
Our report identifies which protected species are present and whether the planned work may have a negative effect. It provides the evidence needed to support environmental permit applications or, if species are affected, exemption requests under the Nature Conservation Act.
