FIVE YEARS WORKING PLAN 37 FINANCIAL ESTIMATION OF THE MAIN EXPENSES 39 Management plan for PODA protected area - Bourgas GLOSSARY OF TERMS Important Bird Area - territory important for the birds after implementation of new BirdLife criteria. Investigated area - the territory of PODA protected area, Phoros bay, Uzungeren PODA protected area (the site; the territory) - the area with borders described in 1.0. Protected area (according to Bulgarian legislation) - piece of nature with typical landscape, valley, gorge, lake and other which may be used as territory for recreation and tourism. SUMMARY OF THE MANAGEMENT PLAN o o Object: PODA protected area; co-ordinates: 27 27'00''E; 42 27'30''N; UTM-grid: NH 30; NG 39; area: 100.7 ha Location: Immediate to the fence of the last building of the town of Bourgas - Shipyard "Ilia Boiadgiev". Conservation status: Protected area since: April 20, 1989. Important Bird Area since: 1989. Management infrastructure: Owner of the site: the state. Manager of the site: Bulgarian Society for the Protection of Birds (BSPB) Description of the site: Historically connected with the Bourgas-Mandra firth. Afterwards the territory has established as the most eastern part of Mandra lake. The intensive human activities after sixties lead to considerable changes in its appearance. It is possible different types habitats to be clarified on its current, comparatively small area - fresh water, brackish, salt, hyperhaline water bodies, overflows, etc. PODA is typical representative of lagoon with secondly developed natural habitats. Meaning: In PODA could be found the unique breeding spoonbill colony for the Black Sea coast. It is nesting together with heron species (grey heron, nigh heron, purple heron, little egret). Regularly in the area as breeding species occur glossy ibis. With special interest are included in Bulgarian Red Data Book species (5 plants and 6 animals), as well as new founded for the country species: plant (Chenopodium botryoides), spider (Callilepis cretica), beetles (Pseudocypus cupreus and Ocypus simulator). The territory of the protected area is a habitat also for other rare plant and animal species. Management policy: To protect the site as a key point for the Black Sea coast and the country, which support great variety of plant and animal species. In near future PODA to became a territory where rare plant and animal species to breed and developed aiming their resettlement in the surrounding areas. Main planing activities: Defining the value and the status of the different sections and making control on the trespassers. Supporting and creating new equipment for nesting birds (pile dwelling and heap islands; heron nests; boxes and platforms for ducks, etc.) Creating and supporting Nature protection and information Centre as well as additional equipment for nature conservation education (ecological route; exhibition in the Centre; advertising materials and souvenirs, etc.). Implementing monitoring programmes on: breeding, migratory and wintering birds; water balans and chemical composition of the waters; plant communities (status and developing); phyto-, zooplankton and zoobenthos (degree of the developing of the water bodies); fish populations (status; food spectrum and their presence in the bird's food); status of the vertebrate (excluding fishes and birds) and invertebrate fauna. Bulgarian Society for the protection of Birds / BirdLife International 5 Management plan for PODA protected area - Bourgas PART 0: PREAMBLE 0.1. POLICY The Bulgarian Society for the Protection of Birds (BSPB) is a voluntary non-governmental organisation. It was established in 1988 with the purpose of conserving and protecting birds and their habitats. In the years of its existence BSPB has won recognition as an operative national organisation based on both a large-scale social support and scientifically-founded priorities and activities. The practical orientation, inner motivation and application of latest environmental methods allowed BSPB to achieve results unknown so far in biological diversity conservation in Bulgaria. The black vulture (Aegypius monachus) was restored to the country's fauna after decades of absence from it. BSPB's high authority is the reason for the Society being involved in all important national environmental initiatives - for instance the National Strategy for biological diversity conservation, the National Programme for biological monitoring, etc.
