Switzerland. Nevertheless, wetlands dry up despite:
While the UN conference on wetlands is held in Zimbabwe, a new study reveals that Swiss peat bogs continue to stop, despite their protected status. Moreover, The 19:30 of the RTS went to the Haut-Marais of Rothenthurm (SZ), the largest in the country.
Despite the rainy state of the weather, the state of certain sectors of the high-marsh of Rothenthurm is not reassuring. Moreover, The vegetation is proof of this, says Ariel Bergamini, who has observed the Swiss marshes for almost 30 years.
“Here, the marsh is clearly too dry. Nevertheless, We see it in the dominance of dwarf shrubs, notably the Callune. In addition, It would not grow if there was enough water,” he explains in the 19:30 of RTS on Saturday.
In normal humidity conditions, the red foam would be omnipresent. However, it is rare today.
“It is these foams that make peat. Thanks to their roots. they carry carbon dioxide in the ground, making peat bogs of important carbon wells,” continues the researcher at the WSL.
Strong increase in dry marshes – Switzerland, wetlands dry up despite
According to his studycarried out for the Confederation. the surface of switzerland, wetlands dry up despite the Swiss peat bogs continues to decrease: 6.5% of the Hauts-Marais have still dried up over the past six years, the equivalent of 100 football fields.
Since 1987 and the acceptance of the Rothenthurm initiative, peat bogs are nevertheless protected. But that is not enough, according to Ariel Bergamini. “Disbellbox is mainly due to the channels of drainage. They were formerly digging them to dry up the marshes. Today, they continue to evacuate the water.”
For Pro Natura. the cantons and the Confederation should invest more to renounce these biotopes of national importance.
Contacted by the RTS. the Confederation indicates that because of its switzerland, wetlands dry up despite poor budgetary situation, it cannot unlock more means at the moment.
