“…Conservation planning and decision making would be better supported (e.g. assessments of representativeness, investment planning and mapping of threatened communities) (Keith and Pellow 2015;Luxton et al 2021). It would also bring Australia in line with Northern Hemisphere methodology, for example, Europe, where the plant community is the unit of conservation targets (Bakker 2013).…”

“…ephemeral montane marshes (lagoons) or ephemeral vegetation types associated with the aseasonal climates found in the arid and semi-arid zone. Luxton et al (2021) use a large plot database (30 000 plots) to develop an updated classification in the northern jarrah forests of southwestern Australia and explore how heterogeneity and representativeness are captured by the conservation reserve system.…”

“…In this case, herbaceous species will influence classification results but have a low correlation with remotely sensed patterns (Neldner and Howitt 1991;Addicott et al 2021). Complexity has also been a barrier to the use of numerical methods in policy and regulatory frameworks and can make the synthesis of historic with current datasets, and across jurisdictional boundaries difficult (Gellie and Hunter 2021;Luxton et al 2021;Muldavin et al 2021). These factors, together with the lack of a critical number of practitioners, have likely stymied vegetation classification collaboration efforts within Australia and internationally.…”

This editorial introduces the Australian Journal of Botany special issue ‘Vegetation science for decision-making’. Vegetation science and classification are crucial to understanding Australian landscapes. From the mulga shrublands of the arid interior to the monsoon rain forests of northern Australia, we have culturally and scientifically built upon the delineation of vegetation into recognisable and repeatable patterns. As remote sensing and database capacities increase, this improved capability to measure vegetation and share data also prompts collaboration and synthesis of complex, specialised datasets. Although the task faces significant challenges, the growing body of literature demonstrates a strong discipline. In Australia, purpose-driven products describe vegetation at broad scales (e.g. the National Vegetation Information System, the Terrestrial Ecosystem Research Network). At fine scales however (i.e. that of the vegetation community), no uniform framework or agreed protocols exist. Climate and landform dictate vegetation patterns at broad scales, but microtopography, microclimate and biotic processes act as filters at finer scales. This is the scale where climate-change impacts are most likely to be detected and effected; this is the scale at which a deeper understanding of evolutionary ecology will be achieved, and it is the scale at which species need to be protected. A common language and system for understanding Australian communities and impetus for collecting data at this scale is needed. In the face of ongoing climate and development pressures and an increasingly complex set of tools to manage these threats (e.g. offset policies, cumulative impact assessments), a nationally collaborative approach is needed. It is our hope that this special issue will help to achieve this.

Context Vegetation mapping is subject to a diversity of approaches and lack of coordination, leading to low repeatability and predictive power in the species-rich flora of the Southwest Australian Floristic Region. Yet it has potential as a tool of use in fire management. Aims This project, extending over five decades, aimed to develop an authoritative vegetation classification and map plant fire responses at Two Peoples Bay Nature Reserve. Methods Using Muir’s classification approach, field surveys were conducted with aerial photography in hand. Thirty-three vegetation units were identified, described, mapped, and photographed. Defining attributes and taxa were identified for each unit. Key results Map, descriptions, and photographs detail forest, woodlands, mallee, scrub thickets, heath, wetlands, and granite communities on the Reserve. The forest, woodland, and shrublands were adequately classified and mapped. However, granite complex and mallee were least satisfactory, oversimplifying a rich diversity of vegetation types and habitats. Conclusions The Reserve may be divided for management into the central third of heath, shrublands, and low woodlands largely across the isthmus, the dunes and wetlands of the west with a greater diversity of vegetation types, and the eastern granite inselberg attaining 408 m with the most diverse vegetation types. The latter inselberg needs continued protection from fire and other disturbances. Greatest change in vegetation is seen in lowland landscapes where fire activity has also been pronounced. Implications Vegetation mapping has been a valuable aid for managers and fire planning, and for active comanagement with appropriate Aboriginal families.
