The project assumes the purchase of land to protect valuable species and natural habitats. As part of the project, 337 hectares of land are planned to be purchased, including: Purchase of 284 ha of parcels containing habitats of selected bird species from Annex I of the Birds Directive Purchase of 3 ha of parcels containing habitats of valuable plant species from Annex II of the Habitats Directive Purchase of 50 ha of parcels containing natural habitats from Annex I of the Habitats Directive. Purchase of land with valuable natural habitats and habitats of valuable bird and plant species. The purchase of land will permanently contribute to the protection of the above-mentioned resources of the Park in areas where this is currently not possible. The purchased land enters the state treasury, which will allow the protection of endangered habitats and species in accordance with state policy and EU standards. The long-term experience of the Park shows that land grabbing/land disposal by the state treasury is a key activity that enables active or passive protection of valuable habitats and species, in accordance with their conservation needs. On the other hand, private landowners, guided by economic interest, strive to maximize revenues from the natural resources (land) available to them. Right now, the park is ok. 38% (≈22 662 ha) of private land, which hinders and sometimes even prevents the effective conservation of BbPN nature. The share of private land within the Park's boundaries leads to habitat fragmentation. In addition, in many cases, the conservation status of valuable natural habitats in private hands is deteriorating due to lack of conservation action or improper use. Over time, these habitats can be lost. On private land there are (data from the draft Protection Plan for the Biebrza National Park): - 1854 ha of habitats threatened on a European scale listed in Annex I of the Habitats Directive, - 22 638 ha of habitats of bird species from Annex I of the Birds Directive - 137 ha of habitats of valuable vascular flora species from Annex II of the Habitats Directive. The planned repurchase is in line with measure No 47 ‘Purchase of sites relevant for the conservation of natural habitats and species’ from the catalogue of active conservation and management activities of the Natura 2000 site included in the ‘Priority Action Framework (PAF) for the Natura 2000 network in Poland for the Multiannual Financial Framework 2021-2027’.
