Planning for population persistence in the face of ecological traps

­My tweetentation (presentation via tweets) for the Inaugural @ARC_CEED Centre of Excellence for Environmental Decisions Twitter Conference #CEEDTC2018. To view on Twitter click here. @kerenraiter

Abstract: We’re using emerging information on species distribution, dispersal & genetic variation combined with insights into varying effects of different land management – incl. ecological traps, to provide cross-tenure decision support for ensuring endangered lizard persistence.

1/6: Integrating population viability & complex threatening processes such as ecological traps, into systematic conservation planning can improve the effectiveness of conservation plans, and encourage land manager engagement : Dror Hawlena Risk Management Lab.

2/6 We explore the challenges of conservation planning in the face of complex realities for critically endangered Israeli fringe-fingered lizards: we modelled species distribution and show devastating historical habitat loss followed by threats of a new sort…

3/ ‘Desert tree’ projects create ecological traps: habitats that lizards quickly colonize, but where the lizards are quickly predated due to trees providing perches for predatory birds. A relatively small area of ‘trap’ can drain lizards from the surrounding landscape

4/6 We are developing simulations to model ecological trap effects on population dynamics and advise land managers how to avoid driving the lizards to extinction. Trap effects vary between species. Collaborators sought!

5/6 Eco-trap simulations will be integrated into landscape population viability analyses informed by genetic analysis of dispersal, geneflow, and population structure, as well as emerging information on grazing, defense-force, agricultural and climate change impacts.

6/6 Integrating these factors will extend the theory and practice of conservation planning; provide cross-tenure decision support for interested stakeholders to help avoid extinction and maximize endangered lizard (& sub-population) persistence. Collaborators invited.
