captive management: full range, below average, above aver- age and best possible, and accounted for the impacts of sto- chastic events (for parameters, see Supplementary Table 1; for methodological details, see Dolman et al., 2015). Outcomes of the captive breeding programme were assessed against the proportion of 1,000 model runs persisting by year 50, whether they provided surplus individuals for re- lease (without compromising the maintenance of a captive population of.20 mature females), and numbers of breed- ing age birds established in the wild, following Dolman et al. (2015).


Assessment process


At ameeting held in April 2019 in Phnom Penh, Cambodia, all relevant stakeholders took part in the application of the IUCN guidelines for assessment of the potential role of ex situ management for the Bengal florican (all participants


are co-authors here), including representatives from the relevant government ministries (Ministry of Environment and the Forestry Administration of Ministry of Agriculture, Forestry and Fisheries), the only NGO working on in situ conservation of the Bengal florican (Wildlife Conservation Society), and the captive facility that had expressed interest in ex situ management of the species (Angkor Centre for the Conservation of Biodiversity). The scope of the meeting and agenda were agreed in advance. Presentations were given to summarize the results of the status review (Step 1) and the demographic modelling described here. Participants worked through the first part of the decision tree to identify the role that ex situ management could play in conservation of the species (Step 2). Presentations were given on case studies of ex situ conservation successes and failures, facil- ities at Angkor Centre for the Conservation of Biodiversity, and ex situ conservation of bustards worldwide.
