The Scientific Council is requested to extend the Working Group as established until the Sessional Committee decides its work is complete or an alternative arrangement is made, focusing its work on the following tasks: a) develop technical guidance for adapting critical habitat criteria to migratory species, including ecological connectivity and subpopulation considerations; b) prepare standard scoping checklists for inclusion of migratory species in EIAs/SEAs, with recommended survey methods and data sources; c) identify best-practice, cost-effective monitoring methods for infrastructure impacts on migratory species; d) support the Secretariat, as appropriate, in the delivery of Decision 15.211.
