The Iron Gates Natural Park (Romanian: Parcul Natural Porțile de Fier) is a 115,666-hectare (285,820-acre) natural park located in southwestern Romania. It includes the Romanian part of the Iron Gate of the Danube River, and stretches along the left bank of the river in the counties of Caraș-Severin and Mehedinți. Across the river is the Đerdap national park in Serbia.

The Iron Gates Natural Park is the second largest natural park in Romania. It stretches from Socol in the west, to Drobeta-Turnu Severin in the east; to the north are the Banat Mountains and the Mehedinți Mountains. The park contains 18 protected areas, the largest one being the wet zone Ostrov–Moldova Veche.

Ecosystem of running water

This comprises the arms of the Danube, and a series of its more important streamlets and channels. It is an environment rich in plankton, worms, molluscs, grubs, and sponges, with numerous species of fish, such as the carp, pike, pike perch, sheat-fish, and freshwater sturgeons (sterlet, Vyza and Danube mackerel).

The climate of the Danube Delta is continental, with strong influences from the vicinity of the Black Sea and its 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. Evaporation is around 1,000 mm/year, amplified by strong and frequent winds, resulting in long periods of drought in the summer. The northwest winds cause frequent storms in spring and autumn. In the interior of the delta, the continental character of the climate is very pronounced.

Reed plants and floating reed islands (called plaur in Romania) are the most common and well known components of the Danube Delta. Vegetation of this ecosystem consists of the common reed (Phragmites communis) and, on near river banks, mace reed/cattail. sedge. etc. They provide ideal spawning and nesting grounds. The plaur are a mixture of reed roots, grass and soil, usually floating or anchored to the riverbed. As a rule, the reed surrounds the lakes and ponds, and slowly invades the water surface.
