“…Following most restoration projects, constructed habitats are typically monitored for 1-3 years, if at all (Bayraktarov et al 2016;Zhao et al 2016). While this time frame captures what is occurring on restored habitats immediately after restoration occurs, managers and practitioners would benefit from a deeper understanding of how communities may respond to restoration over decadal scales (Connell & Slatyer 1977).…”

Long‐term monitoring is vital to understanding the efficacy of restoration approaches and how restoration may enhance ecosystem functions. We revisited restored oyster reefs 13 years post‐restoration and quantified the resident and transient fauna that utilize restored reefs in three differing landscape contexts: on mudflats isolated from vegetated habitat, along the edge of salt marsh, and in between seagrass and salt marsh habitat. Differences observed 1–2 years post‐restoration in reef development and associated fauna within reefs restored on mudflats versus adjacent to seagrass/salt marsh and salt marsh‐only habitats persisted more than 10 years post‐restoration. Reefs constructed on open mudflat habitats had the highest densities of oysters and resident invertebrates compared to those in other landscape contexts, although all restored reefs continued to enhance local densities of invertebrate taxa (e.g. bivalves, gastropods, decapods, polychaetes, etc.). Catch rates of juvenile fishes were enhanced on restored reefs relative to controls, but to a lesser extent than directly post‐restoration, potentially because the reefs have grown vertically within the intertidal and out of the preferred inundation regime of small juvenile fishes. Reef presence and landscape setting did not augment the catch rates of piscivorous fishes in passive gill nets, similar to initial findings; however, hook‐and‐line catch rates were greater on restored reefs than non‐reef controls. We conclude that ecosystem functions and associated services provided by restored habitats can vary both spatially and temporally; therefore, a better understanding of how service delivery varies among landscape setting and over time should enhance efforts to model these processes and restoration decision‐making.

“…Sea level rise has a greater effect on mangroves from carbonate environments', since their adequate functioning depends on the relative elevation of the soil regarding to the flooding level [10]. Moreover, tropical storms and road infrastructure construction frequently have an immediate and severe effect on the hydrological flow regimens in mangrove areas [11]. Thus, it is essential to develop strategies against the effects of global climate change and for the recovery of ecological processes through ecological restoration [12].…”

Determining hydrological flow paths to enhance restoration in impaired mangrove wetlands

et al. 2020

The restoration of mangroves has gained prominence in recent decades. Hydrological rehabilitation has been undertaken to connect impaired mangroves with the sea, lagoons or estuaries. Because mangrove hydrodynamics occurs on the surface and interstitial spaces in the sediment, we propose to determine the hydrological flow paths to restore the hydrological regimes of the impaired mangroves. The hydrological flow paths were determined through a micro basin analysis based on microtopographic data to generate a digital elevation model. Applying this methodological approach, the hydrology of an impaired area on a barrier island in the Gulf of Mexico was restored by excavating, desilting or clearing the channels on the identified hydrological flow paths. This area was compared to one in which impaired mangroves were reconnected to the marine lagoon but disregarding the flow paths. Data collected in both areas were evaluated by flood level analysis, using two methods: (i) a simple linear regression model (SLRM) and (ii) spectral analysis (SA), also known as dominant frequency analysis. The results suggest that restoration based on the hydrological flow paths was more effective than the direct opening to the nearest main water body without accounting for the microtopography. In both areas, soil salinity and sulfides decreased after hydrological reconnection. However, a greater efficiency in the investment of time and human resources was achieved when preferential flow paths were identified and taken into account. The methodological procedures described in this study are of universal application to other mangrove restoration programs.

“…Despite the importance of coastal wetlands and their benefits to society, they are the most degraded ecosystems in the world due to constant human pressure and climate change threats (Zhao et al ). Their ecological restoration (ER) is therefore important to guarantee the benefits that wetlands provide to society.…”

Ecological restoration (ER) of coastal wetlands is extremely important because they provide a huge variety of ecosystem services (ES), but they are the most degraded ecosystems in the world. However, coastal wetlands are usually located in largely modified and densely populated landscapes. Hence their restoration may conflict with cultural values. Therefore, considering the cultural dimension of ER is a way of increasing public acceptance of restoration projects. In this study, we assessed the public acceptance of a restoration project in a coastal wetland of Costa Brava (Spain). We combined the ES framework with a cultural approach, which is capable of considering interdisciplinarity, introducing barely assessed services like tranquility and facilitating further integration of the human dimension in the ES framework.We administered an open-ended questionnaire to 232 visitors and the answers were submitted to a content analysis to get a post hoc classification of services and values. Our results show that visitors undervalue environmental values, while tranquility is the most commonly stated value. Moreover, place attachment is found to be the main driver to influence the perception of the ER. The study concluded that the project enjoys a high public acceptance. However, some disengagement exists between the goals of restoration and visitors' perceptions, and this needs to be addressed. Sharing the decision-making power with stakeholders and informing visitors about ES that are not easily perceived could be appropriate steps to take.
