Research on protected species in and around buildings
Soon, you may come across ecologists in the municipality of Aalten, both during the day and at night. This spring, the municipality is launching a comprehensive study of protected species that inhabit buildings, such as bats, house sparrows, and swifts. This study is part of the development of a Species Management Plan (SMP). With this plan, we aim to carefully preserve natural values in our municipality while also allowing for the maintenance, renovation, and sustainability improvements of buildings.

Ecologists from Ecochore Natuurtechniek B.V. are conducting research on protected species on behalf of the municipality of Aalten, starting this spring and continuing through 2027. This research is being carried out in Aalten, Bredevoort, Dinxperlo, and De Heurne. The research takes place both during the day and at night, as some animal species, such as bats, are active at those times. The ecologists will always be able to identify themselves and will carry a letter signed by the municipality. If you are unsure whether someone is actually working on behalf of the municipality, please feel free to ask or contact us.
Why is this necessary?
Many animals live in and around our homes, barns, and other buildings. Think of nesting sites under roof tiles or hiding places in cavity walls. These species are protected under the Omgevingswet. The SMP study helps us to:
- Map the habitats of protected species
This Map us understand how these species are faring in our municipality. It also helps us identify their habitats and learn how to protect them. - Preventing harm to vulnerable species
By knowing in advance which animals live, eat, sleep, and reproduce in a given area, more targeted measures can be taken. - Preserving an important ecosystem
Bats and birds play an important role in our ecosystem, for example by controlling insects such as mosquitoes or dispersing seeds.
What are the benefits of an SMP?
With a Species Management Plan, the maintenance, renovation, and sustainability upgrades of buildings will soon be carried out more quickly and easily. In many cases, a separate ecological study will no longer be necessary, as this is already addressed at the municipal level. It will also be clear in advance what measures may be needed, such as nesting boxes or alternative habitats.
What does this mean for residents?
In the coming weeks, you may see ecologists in your neighborhood. They will primarily be inspecting buildings in public spaces and municipal properties. Over time, the SMP will streamline the renovation process—since individual environmental assessments will often no longer be required—and promote greater consideration for nature and biodiversity in the local environment.
We will keep you updated on the progress. As soon as the SMP is ready, we will be happy to explain what this means for the work on your home or building.
