As a result of climate change, more frequent and intense bushfires are predicted to occur across the continent. Therefore, it is important to know what happens to restoration plantings when young woody plants are burnt. To this end, we present 8 years of monitoring data from the Scottsdale Reserve in Bredbo, where we followed individual tubestock from 2013 to 2022 with an uncontrolled bushfire occurring in early February 2020. We found that Eucalypt (<i>Eucalyptus</i> spp.), Wattle (<i>Acacia</i> spp.), and Prickly Box (<i>Bursaria spinosa</i>) seedlings planted by volunteers had high survival rates from year to year, even after fire. Non-resprouting species including Hop Bush (<i>Dodonaea viscosa</i>) and Shiny Cassinia (<i>Cassinia longifolia</i>) had not recovered by early 2022, though these represented a much lower proportion of the planting. Our results suggest that some components of restoration plantings are resilient to burning but others are not able to produce viable seed banks, or regrow from them in this setting. Some replanting after fire may be required to maintain desired plant diversity and structure.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"25 3","pages":"177-181"},"PeriodicalIF":1.9,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.12616","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Novel approaches to resolving these conflicts are required to achieve conservation outcomes that are more broadly acceptable. The conservation and management of K'gari wongari (Fraser Island's Dingoes) is emblematic of such a situation. Here we describe the successful implementation of a novel approach to advancing one such formerly intractable issue – assessing the genetic health and status of the island's Dingoes to resolve latent conflicts and assist protected area managers with their conservation activities. We developed a participatory, independent approach centred on community workshops to identify research priorities, expert workshops to identify appropriate research methods, then the commissioning of independent scientific research to address community priorities in accordance with the experts' suggested methods. The overall aim of the project was to provide managers with robust and policy-ready information on the genetic health and status of the Dingoes – information that also met community expectations and was widely supported by subject matter experts. The participatory approach of the project achieved this aim and was completed successfully and satisfactorily for all involved despite the occurrence of some expected challenges and necessary compromises. Here we describe the background to the problem, how the project was designed, the key challenges the project faced during implementation, and the key learnings from the exercise, thereby highlighting its innovative features as a participatory conflict resolution process.

In Australia, veteran or large old trees in natural landscapes are of significant ecological importance, and among the Indigenous communities, they are living monuments to historical cultural practices, but their survival, endurance and long lives are rarely acknowledged to afford them protection. In sub-tropical Australia, the lack of consistent annual growth rings in stem wood makes it difficult to estimate the age of large trees using methods such as the periodic diameter increment. Ngugi <i>et al.</i>, 2020 published radiocarbon (<sup>14</sup>C) dates using wood core (‘pith-wood’) samples from 12 Indigenous culturally-significant trees covering five species on Minjerribah (North Stradbroke Island). Due to the imprecise calendar age results of the single samples used in the original study (Ngugi <i>et al.</i>, 2020), subsequent radiocarbon dating of an additional three wood core samples from each tree was undertaken to age the trees more precisely. The revised tree ages ranged from 63 to 531 years and suggest an important role of past Indigenous land management practices into protecting Bugari (Cypress Pine, <i>Callitris columellaris</i> F. Muell.) from deadly crown scorching fires. These results underscore the importance of incorporating Indigenous practices in current fire management strategies and plans. Estimating tree ages based on the periodic diameter increment method overestimated the age relative to that derived from radiocarbon dating.

Rapid riparian assessment methods are standard tools for capturing a suite of variables relevant to river health and are accessible to a range of users with different levels of experience. Monitoring efforts are particularly important for rivers undergoing degrading impacts and subsequent management interventions. In coastal catchments of New South Wales, Australia, vegetation is returning to rivers that were historically cleared for agriculture and are now experiencing geomorphic recovery. We present a rapid riparian assessment method for rivers undergoing vegetative and geomorphic recovery in this region. It addresses a gap in available rapid assessments by providing a methodology that can be used at sites with no historical analogue. Our assessment method adapts and extends a widely used method called the Rapid Assessment of Riparian Condition (RARC) to capture the quality of returning riparian vegetation along recovering rivers (<i>rec</i>), including native species diversity and vegetation structure (hence the name RARC<i>rec</i>). The RARC<i>rec</i> incorporates four sub-indices – vegetation cover, native species richness, proportion of native to exotic species, and features of vegetation health – to produce an overall vegetation condition score that classifies sites as poor, moderate, or good condition. Scores for each sub-index are assessed for the vegetation strata (groundcover, graminoids, midstorey, vines, and canopy) on the landform units of river bars, benches, and floodplains. The RARC<i>rec</i> has been designed to be sufficiently general for use in the main Vegetation Formations in coastal New South Wales and has been trialled at 36 sites across this region. Assessments can be conducted within half a day by two technically competent users and can be used to monitor vegetation condition over time to inform where to prioritise implementation of management activities. Field methodology and data sheets, including a scoring system, are provided to support the implementation of the RARC<i>rec</i>.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"25 3","pages":"208-222"},"PeriodicalIF":1.9,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.12617","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the extreme drought of 2017–2019, declining water levels threatened Platypus at Tidbinbilla Nature Reserve (TNR), Australian Capital Territory (ACT), Australia. TNR supports a population of Platypus, occupying interconnected ponds within a predator proof fence. During drought conditions in 2019, Platypuses could not move out of the fenced area to refugia as floodgates were closed due to low water levels. In winter of 2019, eight Platypuses were found deceased resulting from starvation. By December, water levels were extremely low and ponds were continuing to dry. Given these circumstances, a rescue intervention was undertaken to capture stranded Platypuses. They were temporarily relocated and housed at Taronga Zoo, Sydney, until they were returned when conditions at TNR improved. Seven Platypuses were rescued, with five successfully housed at Taronga for 5 months. One Platypus was lost after escaping from its enclosure and another Platypus died when trapped in a crevice. The Platypuses were returned after water levels increased at TNR and were monitored for 500 days post-release, demonstrating successful repatriation. This case study outlines the key stages and considerations required for this intervention, providing critical information for rescue attempts on drought-affected Platypus populations. There is a need to continue developing a decision framework for interventions of climate-affected populations, including quantifying trigger thresholds and conservation prioritisation of populations. This will become increasingly necessary given the trajectories of habitat degradation, coupled with the increasingly frequent and severe droughts, expected under anticipated climate change scenarios.</p>\u0000 </div>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"25 3","pages":"199-207"},"PeriodicalIF":1.9,"publicationDate":"2024-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142862162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our study examined the success of this restoration in stands of two ages using species composition as the criterion. The starting point (pasture) and the target (reference woodland) were sampled to document the extent of progress of species composition from pasture through young (3–5 years) and old (9–11 years) restoration stands to reference woodland across three sites at two surveys. Comparisons showed restored stands of both ages differed significantly from pasture, and from each other, showing decreasing similarity between the restoration stands and pasture at all sites. Despite this, species composition in restored stands at all three sites was still significantly different from reference sites, showing that none had achieved the target reference state after 11 years. The trajectory of restored sites between the two surveys was not towards the reference state. Restoration resulted in the establishment of 20 (71%) of the planted species. Recruits from five planted species were found. A further 40 unplanted native ground layer species were found in restoration. Structurally, tree cover increased with time since restoration and was higher in the restored sites. Ground cover, which was very high in pasture was lower in some restored sites. The majority of the unplanted native species were resprouters, and their presence in the above-ground vegetation was most likely by vegetative resprouting from the bud-and-tuber bank as ground cover was lower with the increase in tree cover and shade. Tree and shrub planting by itself has not yet progressed the restored areas to the species composition of reference sites. Additional tools will be needed to assist restoration, specifically the addition of re-seeder native plants not able to persist through vegetative resprouting after restoration.
