  • T7623 - Based on IWC data, van Roomen et al. (2018) reported stable trend for 1995-2017 (0.99) and uncertain trend for 2008-2017 (0.95). Based on updated IWC data and using different site selection and trend analysis techniques Nagy & Langendoen (2020) reported stable trend for 1993-2018 (0.9994) and uncertain trend for 2009-2018 (0.9572). Based on the growth rate of the last 10 years, the population is projected to decrease by 72% in 3 generations compared to the population levels in 2009.
