N2 - This project established a one hectare restoration site within the bittern scar at Useless Loop. The site connects two existing remnant seagrass meadows via 25 plots (each 20 x 20 m), designed to create a marine habitat corridor. The aim of creating a corridor is to reduce sediment movement which may encourage natural establishment of smaller seagrasses from the sediment seedbank and assist seagrass expansion from remnant meadows. The corridor will also provide connection for benthic biodiversity. Several experiments were established within the restoration site to determine whether: (a) the source of adult transplants affects survival, (b) transplant survival is affected by the time of planting, c) month of snagger deployment affects seedling recruitment, (d) shape and size of snaggers affects seedling recruitment, (e) wire weed seedlings are naturally dispersing and recruiting into the site, and (f) quantifying the influence of seagrass on benthic water flow. Results obtained through previous and ongoing monitoring of this site will provide important information on how to improve restoration success into the future, and will indicate how long it will take to restore the site.
