The translocation aimed to augment an existing population with propagated plants to compensate for cleared plants and conduct field research to better understand the effects of soil properties, horticultural practices and a wildfire on translocation results. A novel soil seedbank and fire method applied ex-situ was used to propagate plants for introduction. After an initial attempt at site-wide introduction resulted in widespread mortality of seedlings from a wilt disease, three plot-based experiments were carried out to examine how disease incidence was related to spatial variation in soil properties and horticultural practices. The experiments showed that relatively subtle changes in the clay and sand content of soil strongly affected susceptibility of Singelton Mint Bush seedlings to wilt disease; 12 month old seedlings performed much better than 6 month old seedlings; plants propagated from seed performed better than cuttings, and most of the recipient site represented unsuitable habitat for Singelton Mint Bush. Sufficient Singelton Mint Bush seedlings were established after 3 years, but after a bushfire, the translocated cohort recruited poorly from seed, so that after 6 years, &lt;10% of the total Singelton Mint Bush population in the recipient site was of translocated origin and &gt;90% of in-situ (pre-translocation) origin.

We investigated whether the type of attractant in lures indirectly influences detectability of wildlife on cameras via differential attraction of invertebrates which themselves constitute prey of insectivorous animals. We indexed invertebrate abundance using pitfall and sticky-traps at 36 camera stations deployed in a Latin Squares design for 5 days, with three lure options (peanut-butter, tuna oil and control) in a coastal mosaic, at Cape Otway, Victoria, Australia. We classified vegetation types (habitat) as: low (no or sparse), medium (grass), and high (shrubs) from aerial imagery and estimated their percentage cover at each grid point (medium and high were uncorrelated and included as separate variables in models). We first examine if attractant types or the habitat influence invertebrate abundance and assemblage, and then examine whether invertebrate abundance influences vertebrate detectability on cameras. There was a trend for the composition of terrestrial invertebrate assemblages to be influenced by lure type (peanut-butter, tuna oil and control attractants) and the proportional cover of medium height vegetation within 20 m; however, assemblage composition was clearly influenced by the proportional area of high vegetation cover within 20 m. The detection probability of insectivorous birds increased where medium-sized (2.5–5 mm) flying invertebrates were present whereas insectivorous mammal detectability increased with terrestrial invertebrate species richness. Mammal detections are more likely associated with use of habitats that have more diverse invertebrate communities. This study provides some support to the hypothesis of the indirect mechanism whereby bird detections are influenced by invertebrate attraction to lures. Therefore, lure choice for camera traps is critical and the possibility of guild-level biases in detection suggests that cautious interpretation of results is required.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.12603","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140625906","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}

In agricultural landscapes, major barriers to their recovery are high soil nutrient levels that favour the growth of exotic pasture and other non-native species, high standing weed biomass creating fierce aboveground competition, and rich weed seed and bud banks providing dense emergent seedling competition. Therefore, the return of grasslands to arable landscapes through restoration must rely on overcoming these challenges, ideally by reducing soil nutrients and mitigating the effects of weeds. This study demonstrates the effectiveness of topsoil removal for restoring diverse native grassy communities by direct seeding on sites with a legacy of elevated soil nutrients and competitive exotic vegetation. Conversely, it showed that repeated shallow cultivation (four times over 12 months) to stimulate weed emergence, followed each time by herbicide application, failed to achieve this outcome, at least in the short term (three years). Grassy community restoration is imperative in Australia, but importantly, it must utilise restoration protocols that are as effective as possible so that limited time, money, and resources are not wasted. In this light, the technique of topsoil manipulation may take us one step closer to achieving this goal in agricultural locations, where their loss is most pronounced.</p>\u0000 </div>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140625756","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}

Despite the value judgements inherent in such a concept, these indices provide a currency that is useful for comparing sites for purposes such as to provide a nexus between vegetation proposed to be removed under permit and other vegetation that will be protected or improved as an ‘offset’. The oldest of the reviewed indices – Habitat Hectares, from the Victorian Government – has been the subject of more scrutiny than others but there has been negligible change to it in response to recommendations made. A recommendation of particular significance is for values of the index to respond smoothly to changes in continuously variable observables like foliage cover, rather than discretising the data into broad class intervals. The step-wise jumps in index values that result from discretisation can have the effects of creating false indications of difference between sites or over time and masking actual differences. The index's value for monitoring change is thereby impaired. The Biodiversity Assessment Method of New South Wales is the only index reviewed here that avoids discretisation. However, many of the other recommendations that have been made for changes to Habitat Hectares were adopted in 2003 for a simplified variant of that method – the ‘Land manager self-assessment method’. Therefore, this variant has been used as the basis for a new index – HH2.0 – that retains the simplifications but does not discretise continuous variables or allocate scores in a step-wise manner. The process of translating field observations into scores is automated by a Microsoft Excel workbook, saving time and reducing human error. HH2.0 will suit landowners, land managers, local government and regional authorities, for non-regulatory purposes such as determining what planning protection to apply to an area or prioritising vegetation management among different areas. It requires significantly less gathering of field data than Habitat Hectares, but like that method, it places weight on vegetation's similarity to a long-undisturbed state. No restriction is made on whether it is applied to plots of specified size or shape. A pre-existing set of observational data has been used to retrospectively determine scores under HH2.0 and compare them with Habitat Hectares scores. The data came from 37 sites spanning a range of vegetation types and ecological condition. The root-mean-square difference between the two methods' scores is 5.1 points (out of a theoretical maximum of 100). For reference, Tolsma and Newell (2003) concluded that a difference of 20 points between two Habitat Hectares assessments cannot be relied upon to indicate a genuine difference in ecological condition.

Vegetation condition metrics, which aggregate multiple attributes, are often criticised for simplifying the complexity of biodiversity. A particular challenge is substitution when high-scoring attributes compensate for those with low scores (e.g. high vegetation cover compensating for low growth from diversity). The geometric mean is often suggested for aggregation to reduce these effects. In New South Wales, Australia, the Vegetation Integrity metric, calculated as the geometric mean of Composition, Structure and Function sub-indices, measures the losses and gains in biodiversity values within the NSW Biodiversity Offsets Scheme. However, concern has been raised that Vegetation Integrity underestimates conservation values of derived native grasslands when the Function sub-index (primarily tree-related attributes) approaches zero. We explore this issue using two datasets and compare the current Vegetation Integrity metric with aggregation using the arithmetic mean, adopting a minimum value of 10/100 for the Function sub-index and use of a grassland benchmark for derived native grasslands. Our evaluation draws on a large-scale expert elicitation of conservation values in Critically Endangered Box-gum Grassy Woodlands and 4018 Vegetation Integrity estimates undertaken during development assessments. We find that Vegetation Integrity underestimates conservation values of derived native grasslands and that the problem is widespread. Although evidence most strongly supports aggregation using the arithmetic mean, this change could be disruptive to the Biodiversity Offsets Scheme. Alternatively, a sub-index minimum of 10/100 eliminates underestimation of derived native grasslands without substantial impacts in other circumstances. We found little evidence to support the use of a grassland benchmark, which tended to overestimate conservation values.
