“…The species is listed in CITES Appendix I-II and the Bern Convention Annex II (Gao et al, 2008;Birdlife International, 2017). The Palearctic distribution range of the Great Bustard has decreased due to various threats during the last two centuries (Alonso et al, 2003b;Karakaş & Akarsu, 2009). Throughout the previous decades, many European populations of the Great Bustard have come close to extinction or have become seriously endangered, with the exception being the Iberian and Russian populations.…”

“…Throughout the previous decades, many European populations of the Great Bustard have come close to extinction or have become seriously endangered, with the exception being the Iberian and Russian populations.

“…Various population size studies have been conducted on the Great Bustard in Turkey, with each study producing different results. The most up to date studies give the total population size as approximately 700-1200 individuals (Morales & Martin, 2002;Kılıç & Karakaş, 2005;Palacin & Alonso, 2008;Karakaş & Akarsu, 2009;Alonso & Palacin, 2010;Birdlife International, 2017). The species has two discrete subpopulations in Turkey.…”

“…One of them is located in Eastern and Southeastern Anatolia and the other in the central and inner parts of Central Anatolia (Karakaş & Akarsu, 2009). Recent Great Bustard population status studies have been conducted on a regional basis (Kılıç & Karakaş, 2005;Özbağdatlı & Tavares, 2006;Karakaş & Akarsu, 2009;Karataş, 2012;Azizoğlu, 2013;Karataş & Özelmas, 2013) and the breeding ecology of the Great Bustard in the Muş plain has been studied (Tanrıverdi, 2015). The population status of the Altıntaş Wildlife Development Area and the area between Körhasan -Aktaş -Ortaköy -Başkurt villages have previously been determined (Yarar & Magnin, 1997;Karataş & Özelmas, 2013).…”

The Great Bustard (Otis tarda, Linneaus 1758) is a bird species categorized as "Least Concern" in Europe and "Vulnerable" in the world by the IUCN and listed in both CITES and the Bern Convention Annex II. According to the latest estimates, Turkey's population makes up only 1-2% of the global population, which is represented by 44.000-57.000 individuals. This population study was carried out in 7 different locations in Eskişehir, Kütahya, and Afyonkarahisar provinces between March 2013 and January 2020. In summary, the surveyed areas were recorded as having a total wintering population of 205 individuals, a total breeding population of 100 individuals, and a total summering population of 70 individuals. The surveyed areas represent an average of 17-29% of Turkey's population in wintering period, an average of 8-14% of Turkey's population in breeding period, and an average of 6-10% of Turkey's population in summering period. Urgent implementation of protective measures is required to prevent the population decline of the Great Bustard within the study areas. Detailed ethological studies on the species are recommended as a means of creating new measures to not only stop population decline but to promote population growth to healthy levels.

“…At present, some peripheral populations seem to be declining at the southernmost limit of the species range (e.g. in Portugal, Turkey, Iran, Kazakhstan, Russia, China and Mongolia), where remnant populations are isolated and may suffer from a lack of genetic diversity (Pinto et al 2005, Tian et al 2006, Kessler 2007, Karakas & Akarsu 2009, Oparin et al 2013, Barati et al 2015. One possible explanation for this decline is that populations breeding close to the species thermal maximum have lower growth rates than those in other parts of the thermal range (Jiguet et al 2010).…”

We studied the dynamics and trend of the last extant population of great bustards Otis tarda in Africa. Moroccan great bustards are the southernmost population of this species, and thus show the characteristics of a peripheral population: small size, isolation and low gene flow. Available counts indicate a severe population decline (62% in the last 15 yr), as well as a contraction of the species' distribution. We used a population viability analysis (PVA) to evaluate the quasi-extinction risk and to identify the most important threats. The estimated geometric growth rate of the more realistic of a set of possible scenarios was 0.87 (95% CI: 0.85, 0.89). This implies a 13% annual decline over 50 yr. However, projections derived from these results should be interpreted with caution, because models have a great deal of uncertainty and vital rates from Iberian populations may be different from those of the Moroccan population. PVA showed the negative consequence of human-induced mortality. According to the model that best fits our census data and if present threats remain in the coming years, this peripheral population could go extinct in ca. 20 yr. Agricultural intensification, infrastructure developments and new power lines in rural areas where the species occurs are causing habitat destruction and fragmentation and increasing artificial mortality. Urgent conservation measures, especially to reduce human-induced mortality, are needed to save African great bustards from extinction. We suggest that these findings can be generalized to other peripheral great bustard populations living in highly humanized landscapes.
