I investigate flower preferences in terms of plant origin (native or exotic), and evaluate niche breadth, of introduced honey bees and native bee taxa. I also consider if habitat influences these patterns.Methods This was evaluated through recording flower visitation by honey bees and native bees in the urbanised region of the south-west Western Australian Floristic Region in seven bushland remnants and seven residential gardens over 2years.Key results Both native bees and honey bees visited more native than exotic flora, however native bees visited a higher proportion of native flora than honey bees. The 10-most visited plants by native bees were exclusively native, whereas for honey bees, although their 10-most visited plants were predominantly native plant species, this selection also included exotic plant species. Niche breadth was broader in bushland remnants, indicating a greater range of preferred flora in bushland remnants. Honey bees however visited more plant families in residential gardens. With increased honey bee abundance, this was associated with native bees expanding their niche breadth, which may be a response to reduce competition. Flower preference patterns and niche breadth often differed between habitats, indicating that foraging patterns may be mediated by habitat context.Conclusion Native flora are preferred by bees, and native bees have relatively restricted flower preferences, especially compared with honey bees.Implications High proportions of preferred native flora are needed to support diverse native bee assemblages in urban areas.","PeriodicalId":38939,"journal":{"name":"Pacific Conservation Biology","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135685805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Less common is the recognition that some ecological communities are also at risk and for them to be formally listed. Under the Environment Protection and Biodiversity Conservation Act (EPBC Act) in Australia ~100 communities have been recognised as threatened. This number is likely an underestimate as many ecological communities lack available robust long-term data to facilitate assessment.Aims and methods Using insights from a range of research studies and long-term monitoring in the Mountain Ash (Eucalyptus regnans) forests of the Central Highlands of Victoria, we examine evidence for its listing as a Threatened Ecological Community.Key results The structure and composition of the Mountain Ash ecological community and the key ecological processes that underpin its integrity have been radically altered in the past century. The community is extensively degraded, heavily fragmented, and suffering substantial biodiversity loss. It should be listed as a Threatened Ecological Community under the EPBC Act.Conclusions and implications Insights from long-term ecological monitoring and other studies provide a strong case for listing the Mountain Ash forests of the Central Highlands of Victoria as a Threatened Ecological Community. The community meets four of the six criteria for listing as a threatened ecological community. Under those four criteria, the Mountain Ash forest community should be listed as either Endangered or Critically Endangered.","PeriodicalId":38939,"journal":{"name":"Pacific Conservation Biology","volume":"273 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135556905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite being highly mobile and adaptable, this endangered species has been impacted by fragmentation of its habitat, with an ongoing need for research on its movements in regional areas across its range to gain an understanding of habitat requirements, and to inform conservation plans.Aims This study aimed to determine whether regional differences in movement (distances travelled, revisitations and home range) exist for foraging and roosting behaviour for this species.Methods Movement analysis of satellite-tagged Carnaby’s cockatoos (n=11) across three agricultural regions was conducted.Key results When comparing distances between roosts and daily foraging behaviour, no significant differences were found between regions (P≥0.05). Resident home ranges (home ranges in areas of resident daily movement) of flocks were much larger in the Esperance region, however, showing differences in movement patterns between regions.Conclusions Because flocks were similar in size (n=±300) between regions and used a similar amount of native vegetation for foraging (±20%), we concluded that movement may have been influenced by the spatial separation of patches of native vegetation. In addition, key foraging habitat often occurred within patches of non-native foraging species.Implications The information derived from this research has proven valuable in assessing the use of native vegetation in the landscape, identifying key habitat and determining daily and seasonal movement patterns. In addition, the importance of non-native food sources must be recognised and protection of native and non-native food sources must play a critical role in the species’ conservation management.","PeriodicalId":38939,"journal":{"name":"Pacific Conservation Biology","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135263867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
