These are particularly useful when the eradication of the invasive species may not be possible. Here we apply this approach to identify the impacts of feral water buffalo (<i>Bubalus bubalis</i>) on the northern long-necked turtle (<i>Chelodina rugosa</i>) in the Arafura Swamp Indigenous Protected Area in northern Australia. Understanding the pathways leading to deleterious effects is even more critical when the impact of the invasive species, in this case the buffalo, is not a direct one but rather indirect impacts that occur from the buffalo's role as an ‘ecosystem engineer’. Conceptual modelling of the physical, chemical and biotic changes caused by buffalo to the habitats utilised by <i>C. rugosa</i> over its life stages, and associated responses, indicated the main pathways leading to population decline. These included a reduction in <i>C. rugosa</i> reproductive success and decreased resilience to extended aestivation periods. Buffalo-mediated soil modification may directly increase adult and egg mortalities and interfere with conditions required for successful aestivation and embryo development. Other stressors include predation by other feral species and climate variability. With the pathways leading to population decline identified, mechanisms to address the impacts of buffalo can be designed and effective strategies developed to conserve this culturally significant turtle species. This approach is an effective tool for land managers where species-specific and place-based conservation strategies are needed and is critical to conservation where the stressor cannot be effectively removed.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"27 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.70042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147567088","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 a conservation context, woody shrubs can be problematic if they prevent the establishment of a desired vegetation composition and structure by outcompeting other species for light, nutrients and water. However, there is limited research on effective methods of shrub removal that can provide recommendations to land managers, particularly where the objectives are related to conservation outcomes. We experimentally tested three methods of woody plant encroachment control at a semi-arid ex-pastoral property now managed for conservation: (1) mechanical rolling, (2) rolling and then burning, and (3) burning alone. We found that Rolled and Rolled+Burnt treatments effectively suppressed woody species over the 4-year study period but affected plant community composition and groundcover dynamics differently. While the resulting understorey of these two treatments was more compositionally appropriate for this ecological community, overstorey species were almost entirely absent in recovering vegetation. This suggests that further interventions such as direct seeding or out-planting will be required to restore overstorey components at this site.</p>","PeriodicalId":54325,"journal":{"name":"Ecological Management & Restoration","volume":"27 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/emr.70041","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147565020","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}
