Matching planting methods to species and site conditions is key in seed-based intertidal seagrass restoration

Seagrass meadows continue to be lost and degraded globally. Restoration is one promising emerging conservation strategy combat such losses place seagrass on a pathway net gain. However, successful restoration methods remain limited few species, geographically constrained, with experimental trials comparing planting across species bioregions. This study trialled three seed-based in two bioregions (the temperate north Atlantic southern oceans). Using Zostera marina muelleri this research investigated their influence the likelihood of seedling emergence, shoot growth (i.e. leaf length). emergence was observed at 50 % sites, largely influenced by local site conditions. Each method performed variably relation environmental Dispenser injection seeding resulted highest efficiency for Z. while biodegradable pots hessian bags were more favourable use seeds. Despite all chosen sites deemed suitable from habitat suitability models, low suggests that conditions including wind fetch, redox boundary depth mud- dominant sediments present specific bottlenecks seed germination retention. work demonstrates importance matching life history traits highlights need greater understanding mechanisms overcome restoration.

Evolving nature-based solutions for Australia’s Indigenous estate in 2024 – opportunities and challenges

Globally, there is growing interest and potential for investment in Nature-based Solutions (NbS) to protect, manage or restore ecosystems through incentive schemes including Payment Ecosystem Services (PES), Nature Repair, Carbon Markets, Common Asset Trusts. Collectively, these NbS markets establish interchangeable mechanisms help address biodiversity climate crises, as well socio-economic issues concerning many Indigenous Peoples Local Communities (IPLCs). IPLCs and/or own almost 32% of the world’s land area customary community-based tenure arrangements. Since 2000 several PES have been implemented Australia.

Learnings from the past to inform future ecosystem restoration projects: an Australian perspective

Restoration Ecology, Год журнала: 2024, Номер 32(7)

Опубликована: Июль 19, 2024

Coastal and marine ecosystems provide valuable ecosystem services functions. Unfortunately, these habitats have experienced increasing anthropogenic climate‐related pressures, leading to significant degradation loss not only in Australia but also globally. Hence, the urgency for coastal restoration has never been more pronounced. We present a synthesis of 151 projects on spanning mangrove, seagrass, tidal marsh, kelp, shellfish reef, coral ecosystems. Our findings reveal increased efforts over past 30 years, with an focus reef habitats. Across Australia, most were southeastern noticeable gap Northern Territory. Restoration strategies focused enhancing propagule availability (74%) substrate (42%), additional toward implementing top–down (7%) bottom–up (4%) controls boost natural recruitment. Projects carried out participation mostly research universities (45%), followed by state government entities philanthropy (34%), private companies (16%). Funding came primarily from governmental sources, such as (50%), commonwealth (44%), (19%). outcomes are centered monitoring growth survival resulting both single multiple actions. highlight key factors influencing recruitment across habitat types, where sedimentation species reproductive biology play critical role. While acknowledging that our results represent small fraction Australia's efforts, intent is contribute insights can support large‐scale actions global scale.

Addressing the Policy Gaps and Challenges to Originating High‐Quality Blue Carbon Projects in the Asia‐Pacific Region: A Systematic Evidence Synthesis Bolstered by Practitioner Consultation

Опубликована: Июль 18, 2024

The Asia-Pacific region contains almost half of the planet’s coastal carbon-sequestering (blue carbon) environments (mangroves, salt marshes, seagrasses). These habitats are highly valuable to sequester carbon and mitigate climate change, but under threat throughout region, due in significant part an insufficient policy environment protect, restore, or create new wetlands/blue environments. Using a systematic evidence synthesis we reviewed existing literature on blue policy, found that gaps challenges fall three themes, “Land Tenure Ownership”, “Funding Protecting Blue Carbon Habitat”, “Conflicting Priorities Jurisdictions”, with two overarching issues, inconsistent recognition rights indigenous peoples local communities (IPLCs) women, sea-level rise. This study makes recommendations ensure high-quality projects through improving equitable outcomes, particularly for women IPLCs, reduce barriers implementing projects. include gender sensitive participatory mapping along registry ownership extensive IPLC consultation resolve uncertainties. Recommendations community level benefits beyond individual land owners important address inequity ownership. Where changes rise intentional barrier removal, should be retained by landowner; otherwise, there is little incentive undertake Due limited income results from some credit payments, other crediting non-market methods can considered supplement landowners’ incomes encourage habitat protection. Conflicting priorities between authorities responsible managing wetlands resolved restructuring/streamlining collaborative workshops. Some will require policies amending delegated legislation.

Are restoration plans missing the target? Land tenure and cyclone risks reshuffles priorities for mangrove restoration

Restoration Ecology, Год журнала: 2024, Номер 32(8)

Coastal wetlands, vital for fisheries habitats, have suffered extensive losses. Ecosystem restoration offers opportunities to improve fish catch and restore the valuable services these ecosystems provide. Successful is dependent on choosing a site where feasible, which encompasses biophysical, social, governance, logistical, resource factors. However, factors that influence feasibility such as land tenure (governance feasibility) future climate risks (biophysical are often overlooked in quantitative analyses of selection. We ask how spatial priorities change when considering affected by tenure, cyclone risk, both together. Specifically, we analyzed case‐study mangrove Queensland, there interest restoring coastal habitats support habitats. found rank order planning units was highly influenced cyclones, with cyclones changing ranks clustered regions along coastline variably throughout. In benefit expected be high, but risk substantially reduces feasibility, practitioners could consider strategically planting mangroves near established forest selecting resilient species restoration. Formalizing regulations incentives private holders amending legislation easier permitting additional suggestions addressing challenges. Our study emphasizes importance systematic approaches minimize failure.

Continental-scale shellfish reef restoration in Australia

npj Ocean Sustainability, Год журнала: 2024, Номер 3(1)

Опубликована: Дек. 19, 2024

Shellfish reef ecosystems in Australia have been greatly depleted. Building on earlier trials, a continent-scale restoration initiative was underway by 2019 to restore 30% of their former distribution. Integral elements building and progressing this ecoscape-scale program are outlined challenges discussed. Documenting pathways large-scale informs global commitments see degraded under effective 2030.
