Nature has revived on the holding ponds and their close environment

On the red mud holding ponds that are already covered and fitted into the landscape, the vegetation has revived in recent decades, the animals have come back and the landscape is full of life. Many rabbits, wild boars, foxes and deer live in the surrounding areas, while the European beaver (Castor fibre)—which is notoriously sensitive to water purity—has re-settled in the nearby Szőny-Füzitő channel.

Patches of alkalising grass and sand representing local values ​​can be found in the area of holding ponds. Plant species under nature protection have appeared on the already covered, undisturbed parts of holding ponds: locoweed (Oxytropis), Clematis integrifolia and feather grass (Stipa pennata).

A series of rare and migratory birds (bank-martin, aigrette, crane, stork) nest here because of the many rodents and insects.

The ornithological specialty of the region is the significant role played by the Danube in the winter migration of waterfowls. The number of bird species—for example, divers (Gaviidae), grebes (Podicepidae), Charadriiformes and Anseriformes—has reached 300, which is nationally outstanding.

Especially the singing birds, Paridae, Turdidae and Corvidae nest in the area. In 2009, the highly protected Montagu's harrier (Circus pygargus) was observed nesting just 1 kilometre from the red mud holding ponds. The ​​tall weeds in the area of belt channels host many reed-warblers (Acrocephalus) and petty chaps (Sylvidae).

Protected and highly protected fish species—including Natura 2000 indicator species—are also present in this area of the Danube, the fish stock is rich.

In 2014 we asked some universities and professional institutions to conduct a comprehensive fact-finding survey on the site. The survey showed that our waste recovery activities do not jeopardize the habitat. The recultivation also has a positive impact on habitats along the shores of the Danube. Experience has shown that birds slowly move back to areas that have been undisturbed for a long time; the number of species is continuously growing and the naturalness of the area shows an upward trend. The waste management activity was found not to have adverse effects on the neighbouring Natura 2000 site’s indicator species or habitats. The planting carried out during re-cultivation also had good effects. The survey of the wildlife of recultivated areas did not find any adverse effects either.

 

QUOTE

“Since the recultivation activity (covering, revegetation) was started 20 years ago, the degree and area of dust emission has been decreasing, which means increasingly positive effects for the flora and fauna. Recultivation decreases dust emission, new habitats are formed after planting and spontaneous succession also starts working.
