“…Much opportunity exists in the natural resource community to facilitate mangrove habitat protection and rehabilitation through various techniques (Begam et al, 2017;Donnelly et al, 2017;Sharma et al, 2017), at potentially even larger scales. In Southeast Asia, 15.4% of mangroves that were deforested between 2000 and 2012 ultimately returned back to mangrove, either through natural regeneration or artificial rehabilitation (Richards & Friess, 2016), and some studies have suggested that India and Bangladesh have increased their overall mangrove area due to natural regeneration and artificial rehabilitation (Giri et al, 2008).…”

Concerted mangrove research and rehabilitation efforts over the last several decades have prompted a better understanding of the important ecosystem attributes worthy of protection and a better conservation ethic toward mangrove wetlands globally. While mangroves continue to be degraded and lost in specific regions, conservation initiatives, rehabilitation efforts, natural regeneration, and climate range expansion have promoted gains in other areas, ultimately serving to curb the high mangrove habitat loss statistics from the doom and gloom of the 1980s. We highlight those trends in this article and introduce this special issue of Hydrobiologia dedicated to the important and recurring Mangrove and Macrobenthos Meeting. This collection of papers represents studies presented at the fourth such meeting (MMM4) held in St. Augustine, Florida, USA, on July 18-22, 2016. Our intent is to provide a balanced message about the global state of mangrove wetlands by describing recent reductions in net mangrove area losses and highlighting primary research studies presented at MMM4 through a collection of papers. These papers serve not only to highlight on-going global research advancements, but also provide an overview of the vast amount of data on mangrove ecosystem ecology, biology and rehabilitation that emphasizes the uniqueness of the mangrove community.

“…4) highlight strong sense of place as a potential asset to ecosystem recovery. A large estuary located along Florida's Atlantic coast, and the most biologically diverse estuary in the Northern Hemisphere, the IRL ecosystem attracts many tourists, and has historically been a valued centerpiece of a devoted local community (Donnelly et al 2017. Human attachment to a functional ecosystem, representing combined economic, cultural, and emotional ties developed by the coastal community, has traditionally been strong.…”

It is often a challenge to predict the impact of ecosystem restoration because many critical relationships and feedbacks between natural and human systems are poorly understood. To address this knowledge gap, we introduce a novel framework to characterize restoration dynamics within coupled human-natural systems. Because dynamics surrounding restoration are complex, we investigate the potential for sense of place, i.e., emotional attachment to place, to elucidate relationships between human and natural systems during times of change, such as restoration. Integrating sense of place with ecological metrics, a typology of restoration scenarios that exemplify complex relationships between social and ecological drivers emerges. We propose an identify-visualize-create framework for parsing restoration objectives and curating sense of place around the functional ecosystem state. Achieving coupled human-natural objectives thus requires evaluation of baseline sense of place early in the restoration process and active pursuit of opportunities that build stakeholder attachment over the long term.

“…Rhizophora mangle (red mangrove) is frequently used in living shoreline and mangrove restoration efforts in the southeastern United States, Caribbean, and Central America [40][41][42][43][44]. Traditionally, successful planting of R. mangle on Florida's east coast has a northern limit of approximately 40 km south of Fort George Inlet, where the natural expansion of R. mangle populations is restricted by the frequency of freeze events that drop below −4 • C [45][46][47].…”

“…Rhizophora mangle occupy elevations ranging from +0.06 to +0.49 m, where the base of the mangroves are flooded on average 30% of each day [51]. To imitate the observed hydrology of naturally recruited fringe mangrove stands, R. mangle used for living shorelines are planted in the middle to high intertidal zone [44,52,53]. Frequent inundation alleviates high pore-water salinity and increases phosphorus abundance, but extended periods of submersion can deplete a mangrove's stored oxygen, negatively impacting survival and growth through the accumulation of ethanol [54][55][56][57].…”

“…Rhizophora mangle can withstand a greater range of flooded conditions as they age, due to larger stems and the growth of prop roots above the sediment surface, both of which have lenticels and aerenchyma for the intake and storage of oxygen [58,59]. Rhizophora mangle, ranging from the propagule stage to three-year-old saplings, have been used for restoration purposes [44,60,61], but utilizing seedlings (≤1 year old) is common practice within the state of Florida [62].…”

By combatting erosion and increasing habitat, mangrove living shorelines are an effective alternative to hard-armoring in tropical and subtropical areas. An experimental red mangrove living shoreline was deployed within Mosquito Lagoon, Florida, using a factorial design to test the impact of mangrove age, breakwater presence, and mangrove placement on mangrove survival within the first year of deployment. Mixed mangrove age treatments were included to identify if seedling (11-month-old) survival could be enhanced by the presence of transitional (23-month-old) and adult (35 to 47-month-old) mangroves. Environmental factors were monitored to detect possible causes of mangrove mortalities. Approximately half (50.6%) of mangroves died, and of those, 90.7% occurred within the annual high-water season, and 88.9% showed signs of flooding stress. Planting seedlings haphazardly among older mangroves did not attenuate enough wave energy to significantly increase seedling survival. Breakwaters alleviated stress through a reduction in water velocity and wave height, increasing the odds of survival by 197% and 437% when mangroves were planted in the landward and seaward rows, respectively. Compared to seedlings, deployment of adult mangroves increased survival odds by 1087%. Collectively, our results indicate that sites with a high-water season should utilize a breakwater structure and mangroves with a woody stem.
