Mangyshlak experimental Botanical Garden, Protected botanical garden in Aktau, Kazakhstan.

Mangyshlak experimental Botanical Garden is a scientific institution in Aktau's 10th microdistrict, founded on a permanent expedition base and functioning since January 1972. Its 39 hectares hold 1,270 plant taxa from 250 genera and 88 families, including a dendrological collection of over 600 taxa and a rose collection of 141 varieties by 2020. A separate plot shows the native flora of the Mangyshlak peninsula.

The garden was created on the basis of a permanent expedition by decisions of the USSR State Committee for Science and Technology (No. 61, 1 December 1970), the Council of Ministers of the Kazakh SSR (No. 129, 9 March 1971) and the Presidium of the Academy of Sciences of the Kazakh SSR (No. 59, 25 March 1971). Academicians N. V. Tsitsin and F. N. Rusanov initiated the project, and the garden has operated since January 1972. In 2000 it joined the Institute of Botany and Phytointroduction.

The garden's rose collection held 141 varieties by 2020, and its dendrological collection exceeds 600 taxa, grouped by genus: hawthorn, cotoneaster, rosehip, barberry, honeysuckle, viburnum and ash, plus apricot varieties. A separate plot shows the local flora of the Mangyshlak peninsula, including white mulberry, thin ziziphora, doubtful hawthorn, common blackberry, Schober's saltbush and white dubrovnik.

The garden occupies 39 hectares in Aktau's 10th microdistrict, with sections for conifers, fruit and berry plants, vines, local flora and a rose collection. The grounds are flat and laid out in collection blocks, so allow time to walk between them. The arid Mangystau climate makes midday heat intense; visit in the cooler morning hours and carry water.

Of the 51 rare species in the collection, 19 are broad-leaved trees such as the Turkestan maple and the Caspian maple, 14 are fruit and berry plants including Ledebour's apple and the Niedzwetzky apple, and 12 are conifers such as the Zeravshan juniper and the Turkestan juniper. The garden also holds a rose collection that reached 141 varieties by 2020.
