Societal Impact Statement Large quantities of diverse native seeds are required to scale up global restoration efforts. However, it remains unclear for many ecosystems how the diversity of available seed in commercial stocks reflects the composition of the ecosystems where vegetation is being remade. This study highlights existing shortfalls in the...

Background and aims Field surveys across known populations of the Endangered Persoonia hirsuta (Proteaceae) in 2019 suggested the soil environment may be associated with dieback in this species. To explore how characteristics of the soil environment (e.g., pathogens, nutrients, soil microbes) relate to dieback, a soil bioassay (Experiment 1) was co...

Societal Impact Statement Mixed species plantings present an attractive alternative to monoculture reforestation through their added benefits to biodiversity. Yet there is ambiguity in the use of the term ‘biodiversity’ in carbon and biodiversity markets, which may create perverse outcomes when designing schemes and projects. Here, we review how th...

Climate change and land management decisions have considerably altered fire regimes globally resulting in increased risks of extreme fire seasons. Fire intensity is one characteristic of fire regime which is projected to increase. However, the magnitude and impact of intense fires on plant habitat and life history characteristics (such as the soil...

Translocation is commonly used in the conservation of threatened species to help mitigate the risk of local extinctions. However, translocations are often limited by knowledge of a species ecological requirements that promote persistence in the landscape. Small translocation trials with a strong experimental design can help to address species knowl...

Climate change risk assessments are essential for the successful conservation and management of species under future climates. However, many management plans fail to include such assessments when evaluating threats to species or ecological communities. Species distribution models (SDMs) are versatile tools that can estimate species exposure to shif...

Case study of an experimental translocation of the Endangered Persoonia hirsuta. This case study provides a brief species background before outlining the critical threats and reasons for investigating the translocation potential for P. hirsuta. Details regarding site selection, planting design and early (<1 year) results from post-translocation mon...
