Cyclone Joy flooded sections of the GBR in late 1990 and early 1991, impacting several nearshore reefs.

This has been possible because of collection of pre-protection baseline data, understanding of baseline healthy population size structures, and ongoing surveys of recovering populations (Bruckner, 2009). Reports and journal articles have been published and a metanalysis performed on the results of implementing MPAs (e.g., Santangelo and Abbiati, 2001; Tsounis, 2005; Tsounis et al., 2006; Bruckner, 2009), though the metanalysis has been contentious (Bruckner, 2010; Santangelo and Bramanti, 2010).

Once attached to the substrate, they typically do not move; however, an anemone can use its foot to move to a new location if conditions are unfit for survival. Due to the increasing extent and severity of human impacts in marine ecosystems, restoration of habitat forming species is becoming increasingly necessary after disturbance events.

Dendronepthya australis is a cold water coral found off the coast of temperate New South Wales, Australia (NSW) and is critical habitat for the endangered Whites seahorse, Hippocampus whitei (Figures 4b,d; Harasti et al., 2014; Harasti, 2016). J. Exp. (2013). The Basics The sea anemone is a sessile marine predator of the order Actiniaria. Museum 34, 619647. March 30, 2013 The aim of this study is to understand the ecology of sea anemones in the Terre Adlie region. For example, the octocoral Dendronephthya australis is strongly associated with sponge gardens and soft substrates, and restoration would likely fail outside of these habitats (Poulos et al., 2016). Anemones are generally solitary, though they can also form colonies, with some species employing both life histories (Francis, 1979). 373, 7278. (c) Small, immature C. rubrum colonies in the Mediterranean, (d) the endangered Whites seahorse, Hippocampus whitei, in D. australis, (e) large, mature C. rubrum colonies, (f) mixed sponge and D. australis habitat. This review and the detailed case studies demonstrate that while some octocorals and anemones can provide resilient habitat within reef systems, a greater research focus on their ecology, threats, and restoration potential is urgently required. Because of their colourful appearance, they are named after the Anemone, a terrestrial flowering plant. at http://dx.doi.org/10.1016/0022-0981(81)90159-3. Ecol.
