25th International Congress for Conservation Biology • Auckland, New Zealand • 5-9 December 2011 poor communities also highlights the synergies in areas where, as so often, they overlap. 2011-12-07 11:18 Managing bias among experts to assess IUCN Red List status Garnett, S.T., Charles Darwin University; McBride, M., University of Melbourne; Szabo, J., Charles Darwin University; Burgman, M.A.*, University of Melbourne; In a recent appraisal of the IUCN Red List status of Australian birds an expert panel was convened to help resolve differences for nine of the most contentious taxa. Using a two stage Delphi system initially produced widely divergent opinions on both key data and levels of uncertainty. After the second round greater consensus was apparent, demonstrating that this approach to risk management has value in this setting. However the exercise also demonstrated many of the types of bias in estimation that theory predicts will operate among experts. The strongest bias was towards tight anchoring to existing estimates, although it was later discovered that some of these were wrong by at least an order of magnitude. The exercise also uncovered several instances where advisors to the expert panel were extremely reluctant to reveal all their knowledge for fear ‘their’ taxon would no longer meet the criteria for threatened. 2011-12-06 14:45 Optimal survey effort for threatened species during environmental impact assessments Garrard, GE*, University of Melbourne; McCarthy, MA, University of Melbourne; Bekessy, SA, University of Melbourne; Wintle, BA, University of Melbourne; Imperfect detectability of plants and animals is a significant source of variation in biological surveys for environmental impact assessment. Failure to account for imperfect detection during an impact assessment survey may lead to poor management, inadequate conservation measures and an increased risk of local extinction of rare or threatened species. Estimates of detection probability can inform the specification of the minimum survey effort required to ensure a high probability of detection if the species is present. However, they do not take into account the prior probability of the species’ presence, or the costs of survey, both of which are likely to influence minimum survey effort specifications for threatened species legislation and policy. We estimate the detectability of Pimelea spinescens subsp. spinescens, a critically endangered plant species of Victoria’s native temperate grasslands, using a time-to-detection model. Using decision-theoretic methods, we then demonstrate how estimates of detectability can be used to determine the optimal survey effort for the species, taking into account the relative costs of survey and loss of the species. These estimates will be useful for setting survey effort requirements for environmental impact assessments under threatened species legislation and conservation policy. 2011-12-08 18:30 To fund or not to fund: a Bayesian Network decision support tool for investment in species conservation Gavin Stewart, University of York, York, UK; Kerrie Mengersen*, QUT, Brisbane, Australia; Georgina Mace, Imperial College, London, UK; Christopher Schmid, Tufts Medical Centre, Boston, USA; Jeff McNeely, IUCN, Switzerland; Jegar Pitchforth, QUT, Brisbane, Australia; Ben Collen, Zoological Society, London, UK; The decision of whether or not to invest the limited resources available to conservation into any given species is a complex issue. There are many potential deciding factors most of which are poorly known, and different decision-makers will have different priorities. While a number of different schemes have been proposed, to date, Bayesian Networks for decision analysis have not been widely evaluated. This paper presents three Bayesian Networks that describe the interactive primary factors involved in this decision from the perspectives of three types of decision-maker: a government official, a non-governmental organization and an inter-governmental organization. The species-independent components of the networks were quantified by these experts and the species-specific components were quantified by two expert ecologists for 13 species across a range of taxonomic groups in their area of expertise. Comparisons between networks and across species reveal very similar decisions emerging from networks with substantially different structures, connections and levels of complexity. All three networks led to support for the same ranking of highest and lowest probability of investment. Results suggest that governments and NGOs have different priorities for decision making and may give the various dimensions of their decisions different weighting yet may still arrive at similar conclusions. 2011-12-09 14:00 Biocultural diversity and biocultural approaches to conservation: what, where, and why? Gavin, Michael*, Victoria University of Wellington; Stepp, Rick, University of Florida; We introduce the symposium on biocultural approaches to conservation with an appraisal of the current state of knowledge on biocultural diversity and biocultural approaches to conservation. The concept of biocultural diversity is rapidly gaining prominence and can play a key role in integrating ecological and social aspects of conservation. At its core, biocultural diversity is a geographical phenomenon, based on observations of positive correlations between biodiversity and linguistic richness. We review work to date on these geographic patterns and suggest future directions, including research at multiple scales and a focus on the mechanisms that produce biocultural diversity patterns. We then explore the definition of biocultural conservation, reviewing a spectrum of approaches that vary in the degree to which they focus on biodiversity versus cultural diversity conservation. We also review the main arguments (both ethical and pragmatic) for conservation action that simultaneously seeks to conserve both cultural and biological diversity. We outline the major challenges to implementing biocultural conservation, including the need to engage diverse stakeholders in collaborative efforts, the importance of supportive policies and institutions at multiple scales, and the use of adaptive governance. Finally, we introduce the other speakers and highlight their contributions to the goals of the symposium. 2011-12-08 18:30 Integrating local wildlife research and serious games to engage schoolchildren in wildlife conservation in the temperate forest of Southern Chile Gálvez, N.*, Pontificia Universidad Católica de Chile, Sede Villarrica, CEDEL Centre of Local Develpement, Culture and Education ; Gutiérrez, P., Pontificia Universidad Católica de Chile, Sede Villarrica, CEDEL Centre of Local Develpement, Culture and Education; The temperate forest eco-region of southern Chile is a critically endangered hotspot. Innovative education is needed to engage school teachers and children in conservation. Serious games for education focus on content, but most importantly learning while having fun. Through interdisciplinary work we integrated wildlife research – conducted in the Araucanía Region– with education and design to develop a strategy role-playing board game (i.e. 4 players’ equivalent to 4 endangered species). Since 2006, local issues and dynamics of species have been obtained with camera traps (> 10,000 camera nights), transects, opportunistic findings of signs (e.g. scats, tracks, road kills), local knowledge and available published work. During 2010 we development the game with tests in schools (n=9) and 72 children, 9 teachers and 9 pedagogy students. It is based on the curriculum and evaluated-approved by the ministry of education. The objective is to foster positive attitudes, understanding of ecological roles and natural history of species. Most important is how each player experiences positive and negative effects of human activities such as deforestation, sustainable agricultural practices, fire, tourism etc, while they win and lose lives as the travel through a fragmented human landscape between protected areas. We conclude that serious games should be used as part of local conservation strategies 2011-12-08 18:30 Evaluation on precision of habitat use monitoring data by line transect method based on GPS locations from collared takin Ge, BM, Institute of Zoology, Chinese Academy of Science; Guan, TP, College of Life Sciences, Beijing Normal University, Beijing, China; McShea, W, Conservation and Research Center, National Zoological Park, Front Royal, USA; Powell, Dl, Department of Mammalogy, Wildlife Conservation Society, UDA; Song, YL*, Institute of Zoology, Chinese Academy of Sciences, Beijing, China; The biodiversity monitoring is the most importance work in wildlife management and environmental conservation. The monitoring line transects method was widely used in past decades in biodiversity monitoring but the data precision collected has seldom compared with other methods. 56
25th International Congress for Conservation Biology • Auckland, New Zealand • 5-9 December 2011 The GPS collars were considered as the advanced facilities to collecting data on animal movement and distribution. But the GPS collars are hardly used in the undeveloped countries and regions due to economical reason. We evaluate the accuracy and precision of the line transects on habitat use based on the GPS locations of takin (Budorcas taxicolor) wearing with GPS collar. We use χ2 test to check whether the habitat use data collected from GPS collared animals can be represented by the locations of footprints/ droppings collected on the transect. The results showed that data collected on transects or from GPS locations showed a equal trend in habitat type use. Most of the locations of GPS and footprints/droppings occurred in the broadleaved forest at low and middle elevation in the south aspect. However, there was a significant difference in elevation (Chi square = 19.511, P
