Special-use forests (SUFs) are nature protected areas in Vietnam used to conserve nature and its biodiversity. While the Vietnamese government has managed to increase the size and number of SUFs, biodiversity within these areas continues to decline. To improve protection of these SUFs, co-management has been advocated in Vietnam. Successfully implementing co-management requires decentralization of authority and a certain extent of public involvement in management activities. This paper assesses how and to what extent the governance of Vietnam's SUFs have taken up the challenge of shifting from conventional government-based management to co-management. Current practices of (co-) management were investigated in 105 of the 143 SUFs. The results show that the type of co-management varies little between different categories of SUFs. Nevertheless, a national 'style' of Vietnamese co-management could be identified, labelled 'administrative' co-management; fostering interaction between a variety of actors, but final decision-making power on management remaining strongly in the hands of the provincial government.
