Consequently, recent and future research into the implications for affected biota, and its translation into policy and management, is of vital importance for the conservation of forest biodiversity. The dry sclerophyll forests of south-eastern Australia are affected by changing fire regimes, including having recently been extensively burnt. In this review, we synthesise contemporary research into the responses of dry sclerophyll forest birds to fire regimes, with a focus on contrasts in levels of time since fire, fire severity, fire frequency, and their interactions. We identify and discuss high-priority knowledge gaps and management issues in this domain. Recent studies have gained insights into the complexity of the effects of fire on birds by, for example, showing how avian fire responses are influenced by climate variability. In dry sclerophyll forests, most species that responded to time since fire were less likely to occur where it was short. There were mixed positive and negative responses to increasing fire severity and/or frequency among species in these forest bird assemblages. Given that quantification of the risk of extinction of rare and uncommon birds under increased fire activity is challenging, options for investigating their fire response are proposed. Availability of habitat for birds that flourish where fire is recent, severe and/or regular is unlikely to decline given current trends. We present a management approach that conceptualises large blocks of biologically connected forest with longer fire ages, but otherwise differing fire histories, as biodiversity reservoirs.","PeriodicalId":38939,"journal":{"name":"Pacific Conservation Biology","volume":"53 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":"135702233","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}

Ex situ conservation in seed banks is an important tool for plant conservation. However not all species’ seeds can be stored in conventional seed banks. Data on seed storage behaviour are therefore vital for conservation decision making.Aims To review available seed storage information for the New Zealand (NZ) indigenous seed plant flora, 86% of which are endemic.Methods We compiled seed storage information for the NZ flora from databases and existing literature, and used boosted regression trees models to investigate predictors of seed storage behaviour for NZ woody plants. We used existing global models to predict the likely storage behaviour for the NZ woody flora where this was unknown, to examine the overall contribution that conventional seed banking could make towards NZ plant conservation.Key results Data were available for 412 of 1823 seed plants, of which 83% produced orthodox seeds that can be stored in a conventional seed bank. Of the woody flora, the incidence of non-orthodox seeds was positively correlated with seed mass, plant height, biotic dispersal, and habitat diurnal temperature range. Eighty-one percent of the woody flora are predicted to produce orthodox seeds.Conclusions and implications Conventional seed banking is likely to be suitable for a high proportion of the NZ flora. However, work is required to gain further seed storage behaviour data for NZ species, and to develop protocols for alternative ex situ conservation strategies for non-orthodox species, especially those facing in situ conservation threats.","PeriodicalId":38939,"journal":{"name":"Pacific Conservation Biology","volume":"32 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":"135560181","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}
