Great presentation by @CJWMcClure @peregrinefund #BOUsci21 outlining how the Global Raptor Impact Network GRIN is working with @anthroraptors & the Raptor sub-project of the Covid-19 @biologging Initiative. Together for raptor conservation!

Thanks to those who supported this study, and to you for reading, on behalf of @ajstanbury #BOUsci21 #SESH2 14/14

We believe other taxonomic groups would have higher levels of assessed threat if similar amounts of data were available #BOUsci21 #SESH2 13/14

To sum up. British bird populations have a high level of assessed extinction risk. This can be partly explained by spatial factor and biological differences between taxonomic group. However, results appear to be heavily impacted by data availability #BOUsci21 #SESH21 12/14

It is worth noting that some of the other taxonomic groups to show high levels of threat have well established national monitoring schemes – Butterflies, Mammals #BOUsci21 #SESH2 11/14

Qualifying criteria vary widely across other taxonomic groups. Those with well-established national monitoring schemes tend to qualify a higher proportion of species under Criterion A. It seems likely that a lack of data is an issue for other groups #BOUsci21 #SESH2 10/14

We found three times the proportion of species qualified as threatened under Criterion A compared to Europe. It is unclear how much of this is due to better data availability here. Differences in spatial scales can at least partly explain Criteria C & D #BOUsci21 #SESH2 9/14

Another important factor is data availability. We are very fortunate to have many dedicated volunteers and professional surveyors collecting data. As a result, we have robust information and are able to assess most species against most IUCN criteria #BOUsci21 #SESH2 8/14

Why is our value so high? It is worth bearing in mind that although the same standardised criteria are used, comparability is affected by spatial scale and biological differences between taxonomic groups #BOUsci21 #SESH2 7/14

To put our figure of 46% of species assessed as threatened in GB into context, the comparable figure is 13% for Europe and 14% for other taxonomic groups here. Other groups in GB to show high values are Reptiles, Amphibians, Butterflies and Mammals #BOUsci21 #SESH2 6/14

Our study shows a very high proportion of species (46%) were assessed as being threatened with extinction from Great Britain using the internationally recognised IUCN Regional Red list process #BOUsci21 #SESH2 5/14

Look out for the 2nd assessment of extinction risk published in the journal British Birds on the 1st December, alongside the new Birds of Conservation Concern #BOUsci21 #SESH2 4/14

The IUCN Red list process used standardise criteria to allocate species to Red list threat categories. Three of the five criteria focus on species with small population and range sizes #BOUsci21 #SESH2 3/14

Tune in #BOUsci21, it's gonna be interesting! Including a talk by @CJWMcClure presenting @peregrinefund 's GRIN and @anthroraptors' s GARRN on how joining forces in raptor monitoring worldwide can make a difference for raptor conservation #research #ornithology

Apologies if I seemed briefly distracted while chairing #BOUsci21 Q&A’s just now… watching across the room as a wastepaper basket got destroyed, unable to intervene! Can I claim on @IBIS_journal expenses?
