Species protection for the Bats

Chiroptera (Auswahl heimischer Arten)

All bat species native to Bavaria are strictly protected and secured under European law through Annex IV of the FFH Directive. For impacts on roosts, flight routes and foraging habitats, greeNature plans and delivers the appropriate CEF and FCS measures in accordance with the BayKompV, from replacement roosts and habitat trees through to the securing of winter roosts.

Measures

Typical protective measures for the Bats

🦇

Replacement roosts and bat boxes

Before a roost is lost, we provide functionally equivalent replacement roosts in sufficient numbers, such as bat boxes on trees and facades or permanently built-in roosts on new buildings. As an advance compensation measure (CEF) under § 44 BNatSchG, these replace maternity roosts as well as summer and transitional roosts before the project intervention takes place.

🌳

Permanently securing habitat trees

Old trees with cavities, cracks and loose bark are essential breeding sites and resting places. We permanently withdraw groups of habitat trees from use, develop stocks of old and dead wood, and in this way allow new natural tree roosts to form over the years.

Securing winter roosts

Caves, adits, cellars and bunkers are frost-free overwintering sites. We secure access points with bat-friendly entry openings, improve the internal climate and, where needed, create new winter roosts, timed to the disturbance-sensitive hibernation period from October to March.

🌙

Linear guide structures and light protection

Bats orientate themselves in flight along linear structures. We retain and add to hedgerows, tree rows and bankside vegetation as flight corridors, reduce the fragmentation of flight routes with crossing aids, and cut artificial light at roosts and flight lines.

🌾

Enhancing foraging habitats

An abundant supply of insect prey secures the population. We enhance foraging areas through extensively managed grassland, traditional orchards, watercourse buffer strips and structurally rich woodland edges. Such measures can also be considered as a population-supporting FCS measure in the exemption procedure under § 45 BNatSchG.

Frequently asked questions

All about the Bats

Yes. All bat species native to Bavaria, around 25 in number, are strictly protected and secured under European law through Annex IV of the FFH Directive. Several species, such as the greater mouse-eared bat and Bechstein's bat, are additionally listed in Annex II. The access prohibitions under § 44 BNatSchG (killing, significant disturbance, destruction of breeding sites and resting places) apply regardless of whether the project lies within an FFH site.
Whenever a project removes or impairs breeding sites or resting places, for example when felling roost trees or demolishing and renovating buildings containing a maternity roost. A CEF measure ensures the ecological function of the affected roosts is continuously maintained within the spatial context. It must be effective before the project intervention takes place, which is why replacement roosts are provided with sufficient lead time and their uptake is checked.
CEF measures maintain the ecological function of a specifically affected breeding site or resting place under § 44 (5) BNatSchG, thereby avoiding the prohibited act. FCS measures are population-supporting measures used in the exemption procedure under § 45 (7) BNatSchG. They secure the favourable conservation status of the population where a project is to be approved despite the prohibition. Which approach applies depends on the species affected and the specific circumstances of the project.
A distinction is drawn between maternity roosts, where females rear their young, summer and transitional roosts, and frost-free winter roosts in caves, adits and cellars. Tree-dwelling species change roosts frequently. Suitable tree cavities and cracks are therefore considered essential roosts even where no animal is found there during a survey. Early roost surveys form the basis of any viable species protection plan.
