Noord Commewijne/Marowijne IBA is a Multiple use management Area which means that it has more functions than only nature protection. There is fishery in the shallow lagoons and on the mudflats, and there is legal and illegal hunting in the swamps. As with al wetlands the Noord Commewijne/ Marowijne IBA is important for mankind because of its biological functions such as, nursery for seafish, waterfiltering and protection from rising seawaterlevel. Along with the other wetlands, Bigi Pan, Noord Coronie and Noord Sarramacca these sites are Multiple Use Management Areas wich are managed by the Surinamese goverment. These sites are very vunerable, because of the high productivity which can lead to overexploitation.
The Noord Commewijne/Marowijne IBA is part of an EBA because of the common occurence of three range restricted species, Guyanian Piculet, Blood-colored Woodpecker and Rufous Crabhawk. The mudflats and the swamps are important for the numurous North-American shorebirds.The 1% treshold is met for Scarlet Ibis, Semi-palmated Sandpiper, Semi-palmated plover, Short-billed Dowitcher.
