  1. Directly plant non-woody plants: brackish/saline wetlands

    A replicated, before-and-after study in 2006–2008 on estuarine mudflats in southern Spain (Castillo & Figueroa 2009) reported that planted clumps of herbaceous vegetation survived and expanded, but that an invasive grass colonized some sites. After one year, 75–99% of planted small cordgrass Spartina maritima clumps had survived. Survival varied with location (flat plain < sloping banks). Surviving clumps had expanded horizontally by 1.1 cm/month, on average. Clumps of glasswort Sarcocornia perennis, introduced as fragments within the cordgrass clumps, had also expanded horizontally by 1.8 cm/month. Seedlings of invasive denseflower cordgrass Spartina densiflora appeared in three sites (abundance not quantified). Methods: Between November 2006 and January 2007, salt marsh vegetation was planted into polluted, unvegetated, tidal mudflats in the Odiel Estuary (number of sites not reported). All sites were planted with cordgrass-dominated clumps, collected from natural marshes (1 clump/m2; approximately 20 cordgrass shoots/clump). Sea purslane Atriplex portulacoides, was also planted around the edge of some sites. Expansion was monitored for 21–76 clumps/herb species (further details not reported).

  2. Directly plant trees/shrubs: brackish/saline wetlands

    A replicated, before-and-after study in 2006–2008 on estuarine mudflats in southern Spain (Castillo & Figueroa 2009) reported 90% survival of sea purslane Atriplex portulacoides, one year after planting. Methods: Between November 2006 and January 2007, nursery-reared sea purslane was planted around the edge of some polluted, unvegetated, tidal mudflats in the Odiel Estuary (number of plants and sites not reported). The main area of each site was planted with clumps of herbaceous plants. Survival was monitored one year after planting.
