The aid scheme planned by ANPI is intended to preserve in-situ bat species at risk of extinction located in the operational area. A significant proportion of bat species live in caves under natural conditions, but in Europe most of the species are excluded from these original natural accommodations due to the disturbance, exploitation and closure of these underground accommodations. The majority of herds, which are significantly depleted in numbers, now find shelters in buildings or artificial underground cavities (e.g. mine reservoirs). However, animals are exposed to specific and increased hazards (e.g. stability problems, gas accumulation, direct closure, overheating, disturbance, etc.) in the artificial environment. ANPI’s area of operation has been very well-examined from the point of view of Batfaunistic and international hazards. According to the survey results, there are very large stocks, including the most important domestic populations of critical species (e.g. round hawk bats, long wing bats). For the most endangered species (e.g. large horseshoe bat) the planned project concerns 40-60 % of domestic stocks! In the case of specially protected Natura 2000 marker horseshoe bats, the impact shall be at least 25 % to 30 % for the entire Carpathian Basin population. The planned interventions are intended to directly preserve the population of vulnerable bat species that are in a vulnerable situation. ANPI plans to achieve the agreed objectives by implementing the following 3 main intervention elements: 1: Improvements aimed at restoring degraded and dangerous accommodations of bat species that are at risk of extinction. The objectives of the project are the maintenance and development of high-profile bat accommodations that would be discontinued in a short period of time without intervention. These bat quarters are still home to high-value bat colonies, but based on their present condition, their survival is uncertain and dangerous for bats and humans. The disappearance of a given accommodation can easily result in the destruction of a significant bat population immediately. The aim is to maintain and develop a bat accommodation network that, based on decades of experience, is of crucial importance not only in maintaining ANPI but the entire Carpathian Basin’s cave and building bat tree. 2: Bat protection education and awareness-raising, presenting bats with the involvement of local communities. The aim is to increase the visibility and acceptance of bats at regional and national levels and to broaden the social base that underpins effective protection by means of a permanent and mobile exhibition. Our complementary goal is to promote the general nature conservation and the Natura 2000 network and to develop the love of nature in general. We intend to achieve this by means of appropriate methods for the specific target groups. 3: Reducing light pollution in bat accommodations, helping to create a star-floor park in the ANP area. Our main goal is to reduce the pressure on bat accommodations caused by artificial illumination, supported by research results; through this, the immediate protection and conservation of bat populations. Another important goal is to prepare the development of the Aggtelek Stars Shop Park, to reduce light pollution in the entire zone system of the Aggtelek Biosphere Reserve. Our stated aim is to reduce the environmental impact in general and to increase the environmental awareness of the local population. It’s a total of br. A project with a budget of HUF 150,460,000 can be implemented by ANPI after a project development period of 6 months, during a 32-month implementation period.
