1) The document discusses management of white dunes in the Natura2000 Kennemerland-Zuid area in the Netherlands as part of a project to revive Dutch dune ecosystems. 2) In the late 1990s, management shifted towards more dynamic dune management and experiments reactivating moving dunes after years of stabilization. 3) Lessons learned were that large-scale reactivation projects take over 10 years and follow-up management is needed to remove remnants of prior stabilization and promote new wet dune slacks.
