Anabasis cretacea Pall.

Anabasis cretacea Pall. , Reise 1: 493 (1771).

Native status

Native.

Conservation status

Vulnerable ( VU): A 3 (d), C 1. Currently under protection, category 3 ( Belov 2019).

EOO 44,800 km 2, AOO 16 km 2. Before the recent period of the botanical exploration, the species was known in three districts only and considered to have a limited distribution in Orenburg Region ( Ryabinina 1998). Since then, further localities were discovered ( Golovanov et al. 2018) and the distribution mapped here is even greater.

The species occurs exclusively on open calcareous substrates (chalk, limestone, marl, gypsaceous denudations) in small populations ( Ryabinina 1998, Belov 2019). Although no apparent large-scale decline of its populations was observed, its habitats are fragile and require legal protection because of their being susceptible to anthropogenic pressure (by visiting and pasturing) and destruction by mining, which assumes projected decline of its populations in the absence of protection. Similarly, the species is protected in the neighbouring territories: Bashkortostan ( Martynenko 2021) and Chelyabinsk Region ( Lagunov 2017).

Distribution

Orenburg Region: Akbulak, Belyaevka, Dombarovka, Gai, Novoorsk, Sol' - Iletsk, Yasnyi Districts, Orsk Town (Fig. 68 ).

Previous reports: Ryabinina (1998), Knjazev (2009).

The species occurs in petrophytic steppes, on limestone. It has a limited distribution in the Region.

The species is distributed in Eastern Europe (south-eastern part), Siberia (south-western part), Kazakhstan, western China (Xinjiang).
