Living shorelines aim to enhance the resilience of coastlines hazards while simultaneously delivering co-benefits such as carbon sequestration. Despite potential ecological and socio-economic benefits living over conventional engineered coastal protection structures, application is limited globally. Australia has a long diverse coastline that provides prime opportunities for using beaches dunes, vegetation, biogenic reefs, which may be either natural ('soft' approach) or with an structural component ('hybrid' approach). Published scientific studies, however, have indicated use in Australia. In response, we combined national survey interviews practitioners grey peer-reviewed literature search (1) identify barriers shoreline implementation; (2) create database projects based on sources other than literature. Projects included were those had primary secondary goal assets from erosion and/or flooding. We identified 138 through means sampled starting 1970; number increasing time particularly since 2000. Over half total (59 %) considered successful according their initial stated objective (i.e., reducing hazard risk) 18 % could not assessed success information available. Seventy percent received formal informal monitoring. Even absence support construction Australia, discovered local regional increases use. This suggests are learning on-the-ground, however more generally it was few examples being made available, suggesting barrier sharing among agencies at broader scale.

Coastal wetland resilience through local, regional and global conservation

Опубликована: Янв. 15, 2025

Coastal wetlands, including tidal marshes, mangrove forests and flats, support the livelihoods of millions people. Understanding resilience coastal wetlands to increasing number intensity anthropogenic threats (such as habitat conversion, pollution, fishing climate change) can inform what conservation actions will be effective. In this Review, we synthesize their through lens scale. Over decades centuries, have unfolded across local, regional global scales, reducing both extent quality wetlands.

Mangrove ecology guiding the use of mangroves as nature‐based solutions

Journal of Ecology, Год журнала: 2024, Номер 112(11), С. 2510 - 2521

Abstract Mangroves are implemented as nature‐based solutions (NbS) for coastal protection, climate change mitigation (carbon sequestration) and other services. They play a core role in providing benefits biodiversity, livelihoods human well‐being. Ecological research has informed the use of mangroves NbS, but failure NbS projects often been due to misconceptions about mangrove ecology limited wide range ecological knowledge available. Enhanced spatial temporal variation processes, differentiation among tree species assemblages (including fauna microbial communities) provision ecosystem functions services, will support successful NbS. Knowledge responses interacting pressures uses zone resilient projects. Synthesis . The success can be improved with increased incorporation plants, animals microbes by sharing co‐producing within societies.

Reversing functional extinction: successful restoration of eradicated oyster reefs

Restoration Ecology, Год журнала: 2024, Номер 32(5)

Опубликована: Май 6, 2024

Functionally extinct ecosystems, those that have been locally eradicated save for remnant individuals, are unlikely to naturally recover over meaningful human time frames. However, ecosystem restoration provides opportunities reverse functional extinction by rapidly addressing the physical and/or biological barriers prevent natural recovery. Here, we assess progress of a native Flat oyster ( Ostrea angasi ) reef in South Australia was from Australian mainland approximately 100 years ago. In absence any reference ecosystems region, assessed relative ecological targets informed combination local rocky and an interim model Australia's sole remaining O. reef, Tasmania. Two half after initiated via construction 14 boulder reefs, observed densities restored adult (192 ± 19 m −2 ; mean 1 SE) exceeded on reef. Communities macroinvertebrates represented 60% biodiversity healthy systems, while functions (e.g. filter feeding) demonstrably increasing. The rate recovery this benthic ecosystem, functionally within several years, demonstrates latent resilience degraded communities capacity effective marine restorations achieve rapid recoveries.

Link marine restoration to marine spatial planning through ecosystem‐based management to maximize ocean regeneration

Aquatic Conservation Marine and Freshwater Ecosystems, Год журнала: 2023, Номер 33(11), С. 1387 - 1399

Опубликована: Авг. 7, 2023

Abstract The speed at which marine and coastal ecosystems are being degraded due to cumulative impacts limits the effectiveness of conservation strategies. To abate ocean degradation allow regeneration, planning needs be improved ecological restoration will needed. This study explores potential incorporating into spatial (MSP) anchored ecosystem‐based management (EBM), termed EB‐MSP, for maximizing regeneration. perspective explicitly brings both passive active restorations EB‐MSP in a broad holistic framework achieving recovery ecosystems, their functions valuable services. By proposing restoration‐focused framework, we highlight co‐benefits interlinking MSP through EBM core principles. Such benefits include scaling‐up effectiveness, greater guarantee that sustainability goals met improvements as an integrated tool with address climate change. Together, this promote regeneration alongside sustainable use prevent further much‐needed recovery.

Habitat management and restoration as missing pieces in flats ecosystems conservation and the fishes and fisheries that they support

Fisheries, Год журнала: 2025, Номер unknown

Опубликована: Фев. 24, 2025

ABSTRACT Flats ecosystems are dynamic, shallow, nearshore marine environments that interconnected and provide immense ecological socio-economic benefits. These habitats support a diversity of fish populations various fisheries, yet they increasingly threatened by anthropogenic stressors, including overfishing, habitat degradation, coastal development, the cascading effects climate change. Effective management restoration essential but often missing for flats ecosystems. Despite navigating landscape imperfect knowledge these systems, decisive action implementation protection is currently needed through policy practice. We present comprehensive set 10 strategic guiding principles necessary integrating conservation flat include calls ecosystem-based ­management, adaptive strategies leverage diverse partnerships, scientific research, legislative initiatives, local traditional knowledge. Drawing on successes in other environmental realms, we emphasize importance evidence-informed approaches to address complexities uncertainties aim advance restoration, promoting integrity strengthening resilience important environments.

Fish use of restored shellfish reefs extends beyond the reef edge

Restoration Ecology, Год журнала: 2025, Номер unknown

Опубликована: Апрель 17, 2025

Global loss of shellfish reefs has necessitated widespread restoration efforts, with fish population enhancement a key motivator. Restoring often involves creating multiple individual reef patches to maximize services within given budget. How patch arrangement influences utilization is valuable information for optimizing designs but remains largely unknown. We used remote underwater video stations monitor on edges (0 m) and at distances 2, 7, 12, 500 m away. For 12 m, we surveyed an inner zone that penetrates the complex outer surrounding it. detected 22 species across 66 camera deployments. Species richness was similar between zones highest edge. assemblages were also zones, three distinct communities present: one 0 cluster including another m. Most species, bluespotted goatfish ( Upeneichthys vlamingii ), leatherjackets Monocanthidae spp.) southern squid Sepioteuthis australis ) more abundant alongside than Habitat use, measured as frequency occurrence in footage, mirrored abundance patterns, suggesting show stronger site fidelity. Individuals restored utilize area least around patches, providing some support status quo form network habitat possible inclusion unstructured areas assessments benefits enhancing habitat.
