The area still faces many threats.
One of them is the pollution of water and soil.
Many streambeds contain severely polluted sediments, a remainder from the sixties and seventies, when the rivers Rhine and Meuse were much more polluted than they are today.
Because there is little net flow in the Biesbosch (because the connection with both rivers and the sea has been blocked, although this will change in the future) the build-up of polluted sediments in the Biesbosch has been severe.
Completely restoring the Biesbosch ecosystem cannot happen without an extensive cleanup of all the creeks, which will be an enormous and costly task.

Another threat to the Biesbosch ecosystem is the extensive water recreation in the area.
The Biesbosch has, however, both strong natural and recreational values, so banning all recreational activities in the area is not an option.
Finding the right balance in this issue will be a challenge.
Other threats include the construction of yacht-basins, urban expansion and plans for exploitation of natural gas reserves.
