The wet area of the Danube in Romania, until 1964, covered 3,322 km2 and formed an authentic delta. Grigore Antipa claimed in 1910 that the Danube from the entrance to the country and the Black Sea had a flood area of 891,232 ha, from which if the surface of the Delta (404,748 ha) is reduced, it follows that the Danube Moon as a distinct geomorphological formation, stretched on 4,865 km2.
From this, the former Braila Wetland occupied in path 149,000 hectares, of which half with Braila Domain is presented in the image attached.
Everything that nature created here in centuries of evolution was destroyed by the embrasures, desiccations and deforestation of the 6th and 7th decades of the last century.
Thus, the wetland has been reduced 5 times, to the 17,529 ha protected in the Balta Mica Natural Park of Braila, the area representing 11% of the former Balta of Braila and 0.5% of the former Lower Lunca of the Danube (the segment of the river from Silistra to at the confluence with the Prut).
By Law no. 5/2000 for the approval of the Plan for the development of the national territory, the Brazilian flood zone is mentioned under the name Balta Mica of Braila, in annex I, in the list of Biosphere Reserves, national or natural parks.
By the G.D. 230 / 4.03.2003 regarding the delimitation of the biosphere reserves, national parks and natural parks and the constitution of their administrations (MO 190 / 26.03.2003), Balta Mică a Brăilei Natural Park was recognized and officially the status of the Wet Zone of international importance, obtained in 2001. In fact, the Administration of the Balta Mica Natural Park begins to operate from August 8, 2004, based on the administration contract no. 744 / 25.05.2004, concluded between the RNP ROMSILVA and the Ministry of Environment and Water Management.
