Kamchia Reserve

Kamchia is a unique and globally renowned nature reserve located in Eastern Bulgaria, positioned along the lower course of the matching Kamchia River. It was officially declared a protected territory by a designated Decree issued on June 29, 1951, by the historical Ministry of Forests. Due to its outstanding conservation, scientific, and ecological significance, during the extended chronological timeline spanning from 1977 to 2017, the reserve was integrated into the prestigious global network of biosphere reserves under the Man and the Biosphere program managed by UNESCO, engineered for the long-term protection of the planet's most representative ecosystems. In 2020, the reserve was officially excluded from this international framework. The initial resolution for this exclusion was enacted by the National Committee for Man and the Biosphere in September 2016, following explicit negative evaluations and reports submitted by the municipalities of Dolni Chiflik and Avren, upon whose shared administrative-geographical territories the boundaries of the reserve position. The primary state objective governing the reserve is the complete stabilization and preservation of the authentic structure and natural evolution of the unique alluvial longoz forests along the lower course of the river. Characteristics and Flora Assets of the Longoz Forest The specific periodically flooded dense forest in the region is designated as longoz, and the core purpose of the reserve is to safeguard its primary wild appearance, which strongly resembles an equatorial rainforest inside Europe. The forest massif displays monumental dimensions, with the dense tree canopy reaching an impressive 50 meters in vertical height at specific humid sectors. Within the structure of the longoz forest, scientists have thoroughly mapped approximately 40 distinct species of trees. Present among them are Pedunculate oak, Alder, White poplar, Wild pear, Willow, South European flowering ash, and an array of other variants, though the overall composition is heavily dominated by Field elm and Field ash. A major portion of the ancient trees in the core of the reserve exceeds a biological age of 150 years, maintaining an average canopy height of over 35 meters. The shrub layer is densely populated by European blackberry, Hawthorn, Rosehip, Cornel dogwood, Hazel, and wild ivy. Holding particular structural weight for the authentic silhouette of the jungle are the climbing lianas, which drape in heavy, massive curtains over the most humid and shaded recesses. They are represented predominantly by Clematis vitalba, Wild grape, and Mistletoe. The humid territory of the reserve also hosts one of the largest and most pristine wild populations of the medicinal Summer snowflake (Leucojum aestivum) within the Republic of Bulgaria, while the slow-moving river channels foster delicate white water lilies, yellow water-lilies, and other rare aquatic plants. Rich Faunal World and Biodiversity Profile The ecosystem of the Kamchia Reserve provides critical feeding grounds and shelter for hundreds of vertebrate and invertebrate species, with a total of 47 vertebrate species originating from the reserve's fauna inscribed in the national Red Data Book of Bulgaria. Distribution of the Wildlife Profile Across Main Biological Groups: Mammals Large mammals live and reproduce securely within the ancient forest tracks, incorporating Red deer, Roe deer, Wild boar, Red fox, European badger, Golden jackal, and European wildcat. Across the reserve's parameters, 26 distinct species of small mammals have been scientifically verified and documented. Holding exceptional interest for zoologists is the European pine vole, which typically inhabits deciduous mountain forests in Bulgaria at elevations exceeding 800 meters. Along the entire Bulgarian Black Sea coast, this species is isolated and recorded exclusively inside the specific microclimates of Kamchia and Ropotamo. Another highly critical species in terms of global conservation metrics is the Eurasian otter (Lutra lutra), which is strictly protected under the IUCN Red List and the Bern Convention. Birds The territory of the reserve operates as an ornithological hub of global magnitude, hosting 258 officially verified species of birds. This impressive metric constitutes 66 percent of all bird species ever recorded across the Republic of Bulgaria. Among them, 56 distinct species are listed with strict protection statuses inside the Red Data Book of Bulgaria. The Kamchia Reserve stands as the only verified wintering ground in the country for the rare Common pochard. Recorded within the protected zone are 118 bird species displaying an unfavorable European conservation status tracking the international metrics developed by BirdLife International, with 32 of these species nesting actively inside the forest canopy. Among the rarest birds across Bulgaria and Europe breeding successfully within the longoz are the Black stork (Ciconia nigra), Lesser spotted eagle (Aquila pomarina), the swift Eurasian hobby (Falco subbuteo), Northern goshawk (Accipiter gentilis), European honey buzzard (Pernis apivorus), alongside seven of the nine woodpecker species distributed across the European continent. For the stable nesting and reproduction of the Middle spotted woodpecker and the Semi-collared flycatcher, the Kamchia Reserve functions as one of the most critical and vital habitats across all of Europe. Fish and Ichthyofauna The regional fish diversity encompasses approximately 40 species, including 8 specialized species migrating seasonally from the marine waters of the Black Sea. Within the freshwater channel of the Kamchia River alone, 25 separate species of fish are permanently recorded, constituting the vast majority of the overall Bulgarian freshwater ichthyofauna. Seven rare species from the reserve's fish treasury are strictly protected inside the national Red Data Book, highlighted by the Wild carp (Cyprinus carpio), Caucasian dwarf goby (Knipowitschia caucasica), and the Nine-spined stickleback (Pungitius platygaster).
