The author presents the results of the HUNGARIAN GEESE MONITORING (Table 1.) for 2021/2022 in the form of a data base. After reviewing the basic data recorded at each site of observation (Table 3-21.) he analyse the obtained data separately for each species, i.e. Brent Goose (Branta bernicla) (Table 22., Map 1., Figure 1-2.), Barnacle Goose (Branta leucopsis) (Table 23., Map 2., Figure 3-4.), Red-breasted Goose (Branta ruficollis) (Table 24, Map 3., Figure 5-6.), Bar-headed Goose (Anser indicus) (Table 25, Map 4, Figure 7.), Greylag Goose (Anser anser) (Table 26., Map 5., Figure 8-10.), Tundra Bean Goose (Anser serrirostris rossicus) (Table 27., Map 6., Figure 11-13.), Taiga Bean Goose (Anser fabalis) (Table 28, Map 7, Figure 14.), Pink-footed Goose (Anser brachyrhynchus) (Table 29., Map 8., Figure 15.), White-fronted Goose (Anser albifrons) (Table 30., Map 9., Figure 16-18.), Lesser White-fronted Goose (Anser erythropus) (Table 31., Map 10., Figure 19-20.), as well as for the total of observed geese (Table 32., Figure 21-23.). In respect of dominance – when data recorded monthly in each of the observed sites (Table 3-21., Figure 24.) or those referring to the total of geese present in Hungary (Table 33., Figure 25.) are analysed, it is found that in conformity with the numbers of individuals, also in the season 2021/2022 White-fronted Goose was the most common goose species in Hungary (max. 274 907 birds, max. 93%), followed by Greylag Goose (max. 55 864 birds, max. 100%), Red-breasted Goose (max. 249 birds, max. 0-1%) and Tundra Bean Goose (max. 205 birds, max. 0-1%) ranking third and fourth. Dominance of Lesser White-fronted Goose – a globally threatened species – ranged from 0% to <1% (max. 26 birds). If the data obtained for the season 2021/2022 are fitted into the database of long-term monitoring, the following conclusions can be drawn from the actual changes in population numbers of the geese species in the Pannon region. In the season 2021/2022, we observed max. 1 Brent Geese, max. 9 Barnacle Goose, max. 2 Bar-headed Goose, max. 1 Pink-footed Goose and max. 5 Taiga Bean Goose. For the globally threatened Red-breasted Goose may be considered higher (two times – 249 birds) to the maximum counted in the season 2020/2021 (147 birds), but much lower to the record number counted in the season 2014/2015 (1258 birds). Greylag Goose continued to be present with high numbers in Hungary. However, in the new season its peaks (55 864 birds) were found to be higher (+42%) those counted in the previous 2020/2021 season (39 261 birds). Peak number of Tundra Bean Goose (205 birds) was lower (29%) as the maximum counted in the season 2020/2021 (711 birds). The dramatic decline in the dynamics of the Tundra Bean Goose population continued in the Pannon Region. Peak number of White-fronted Goose (274 907 birds) was 4% higher as the maximum counted in 2020/2021 (265 010 birds). For the globally threatened Lesser White-fronted Goose may be considered higher (26 birds) to the maximum counted in the season 2020/2021 (10 birds). The maximum numbers of total geese in the season 2021/2022 registered simultaneously (321 729 birds) was 5% higher to the maximum number of the season 2020/2021 (306 526 birds).
