The Danube Delta is the second largest river delta in Europe, after Volga Delta, and is the best preserved on the continent.The greater part of the Danube Delta lies in Romania (Tulcea county), while it`s northern part, on the left bank of the Chilia arm, is situated in Ukraine.

3. • The modern Danube Delta began to form after 4000
BCE in a bay of the Black Sea, when the sea rose to
its present level. A sandy barrier blocked the Danube
bay where the river initially built its delta.
• Probably 40 percent of the Delta was built in the last
1000 years. Finding that was like a eureka moment
• At present the delta suffers from a large sediment
deficit after the construction dams on Danube and its
tributaries in the later half of the 20th Century.

5. • The climate of the Danube Delta is continental
with strong influences from the vicinity of
the Black Sea and it`s prevalent amphibian
environment. It is the driest and sunniest
region of Romania. The mean annual
temperature is 11 °C (-1 °C in January and
22 °C in July), with mean precipitation
between 400 mm/year and 300 mm/year,
decreasing from west to east.

6. • The Danube Delta falls within Pannonian steppe
ecosystem of eastern Europe, with Mediterranean
influences. As a young region in full process of
consolidation, the Danube Delta represents a very
favourable place for the development of highly
diverse flora and fauna, unique in Europe, with
numerous rare species. It hosts 23 natural ecosystems,
but due to the extent of wetlands the aquatic
environment is prevalent; the terrestrial environment
is also present on the higher grounds of the
continental levees, where xerophile ecosystems have
developed.

7. • Situated on major migratory routes, and
providing adequate conditions for nesting and
hatching, the Danube Delta is a magnet for birds
from six major eco-regions of the world,
including the Mongolian, Arctic and Siberian.
There are over 320 species of birds found in the
delta during summer of which 166 are hatching
species and 159 are migratory. Over one million
individuals (swans, wild ducks, bald coots, etc.)
winter here.

8. • It comprises the Danube arms, as well as a
series of more important streamlets and
channels. It is an environment rich
in plankton,worms, mollusca, ephemerides, gr
ubs, spongiae, with numerous species of fish,
such as the carp, pike perch, sheat fish, and
freshwatersturgeons (sterlet, Vyza and Danube
mackerel).

10. • Recorded history first noted the Delta
under Dacian control before being
conquered by the Romans. After invasion
by the Goths the region changed hands
many times. During the 15th century, the
Danube Delta became part of the Ottoman
Empire. In 1812, following the Russo-
Turkish War the borders of Ottoman
and Russian Empires were set by Kilia and
Old Stambul Channels of Danube, and in
1829 by St George Channel.
