Taylor, RB. & D Frobel. 1990. Approaches and results of a coastal dune restoration program on Sable Island, Nova Scotia. Proceedings Canadian Symposium on Coastal Sand Dunes, Guelph, 1990. NRC Associate Committee on Shorelines. pages 405-431.
Note (ZL): When this report was published, the authors, Bob Taylor and Dave Frobel, were with the Atlantic Geoscience Centre (Geological Survey of Canada) based at the Bedford Institute of Oceanography in Dartmouth. In this paper, they presented observations from several dune blowouts and deflation channels to illustrate the variety of approaches taken to repair the “coastal foredune” on Sable Island, and to describe the longer-term morphological changes that resulted from the terrain restoration program. The magnitude of changes observed depended primarily upon i) the frequency and direction of sand-entraining wind (i.e., wind that is carrying/moving sand grains), ii) the abundance of mobile sand, iii) the frequency of seawater flooding, and iv) beach stability. The authors report that foredune repair and terrain restoration was most successful at sites where flooding was stopped and vegetation spread across the inner blowout. The latter was the result of transplanting and/or natural propagation of marram grass (Ammophila breviligulata). At one such site, as much as 4.5 m of sand was trapped and stabilized over a ten-year period.
Funding for the restoration program was provided mostly by the offshore energy industry, particularly Mobil Oil Canada Limited. Zoe Lucas supervised the Sable dune restoration program from the late 1970s through to the mid-1990s. In the mid-1990s, the uncertain future of the Sable Island Station resulted in suspension of the terrain restoration work.
