Working Group 3: Drivers of population distribution and growth

All available evidence regarding factors determining parakeet distribution, abundance and population growth rate across Europe will be reviewed. For this review information (spatial and temporal) will be drawn from multiple sources, including current IAS and biodiversity-related information-systems, and data from published/unpublished reports. The review will also incorporate information from the native range of parakeet, and from other areas outside Europe where it is also an invader. WG3 will comprise Action participants (particularly with expertise in demographic and ecological modelling), data providers and database managers, national scientific and other expert contributors including from the IUCN ISSG and EC.
Task 1: Conduct systematic review of existing information and data in terms of data type, quality and geographic coverage. This process will involve thorough interrogation of all existing IAS-relevant information systems for parakeet data (including databases not in the public domain), alongside consultation with relevant expert contributors from IUCN ISSG, ISC, NOBANIS and GISD.
Task 2: Prioritize utility of data for informing essential demographic parameters and identify important data gaps that need filling. STSMs will be targeted to address data/knowledge gaps, following input from Action participants (demographic and ecological modellers) and expert contributors.
Task 3: Synthesize accumulated data sets (to include initially those on climate, land-use, habitat availability and diversity, genetic diversity and evolutionary origin) and explore temporal and spatial patterns to identify factors limiting parakeet population distribution and growth across Europe (linking to WG1).
Milestone 1: Report on parakeet data in existing information-systems and recommend key analyses.
Milestone 2: Recommend data/studies required to fill knowledge gaps and align to STSMs.
Milestone 3: Publish analysis identifying limiting factors.
