Research on bats, house sparrows, and swiftlets in Krimpen aan den IJssel
From April to September, Blom Ecology will conduct research again in Krimpen aan den IJssel. This study is necessary to protect protected animals, such as bats, house sparrows, or swiftlets, during the renovation or insulation of homes.
The research is part of the development of a species management plan (SMP). In this plan, we will outline how we will protect vulnerable animal species in Krimpen during new construction, renovation, or insulation of homes and other buildings.
How to recognise the researchers
The researchers from Blom Ecology carry out their work at different times of the day. After all, the activity of these animals varies by species. It is also possible that you may see the researchers working on the streets at night. The exact days depend on the weather conditions.
The researchers cycle through Krimpen aan den IJssel. They wear a vest with the Blom Ecology logo and often carry an orange bag with their logo.
They remain on public roads and do not enter private property uninvited.
Why are we conducting this research?
Protected animals such as bats, house sparrows, and swiftlets often live in and around homes or buildings. They like to nest under roof tiles or in cavity walls. During insulation or renovation, their habitats may unintentionally disappear.
Bats are important
It is not only mandatory to protect these species; it is also crucial that these animals continue to have a place in Krimpen. Did you know that a bat can eat 1,000 mosquitoes and other pest insects in a single night? If a species disappears, this also affects other species. They may disappear as well—or, conversely, their numbers may explode.
Municipality of Krimpen aan den IJssel is working on a Species Management Plan (SMP)
Disturbing or killing protected animals is legally prohibited. Therefore, any insulation or renovation project requires a separate ecological study and a permit. This can be time-consuming and costly.
In Krimpen aan den IJssel, we are conducting one major study. After this, we will develop the Species Management Plan (SMP), which will outline how we will manage protected species in our municipality. Based on the SMP, we will apply to the province for one permit to allow insulation or (re)construction throughout Krimpen. This means that individual homeowners or property owners will no longer need to commission their own ecological studies, which can take a lot of time and easily cost €5,000.
In the meantime: nature-friendly insulation
Until the SMP is finalised, a limited number of homes and buildings in Krimpen may be insulated in a nature-friendly manner. Would you like to get started with this? On the website of Krimpen Duurzaam, you can read more about natuurvriendelijk isoleren.
