“…The Munkh Khairkhan site (site D) (2730 m asl) is situated near the upper border of the mountain steppe with a variety of Poaceae that grades to alpine vegetation rich in Cyperaceae like Kobresia humilis and Carex rupestris . The endemic Caryophyllaceae Stellaria pulvinata grows between 2600 and 3300 m asl, and Potentilla nivea is found from the mountain steppes up to about 3000 m asl (Bocharnikov et al, 2015). The very restricted forests of the Mongolian Altai are dominated by Siberian larch ( L. sibirica ).…”

Glacial and lacustrine sediments from the Mongolian Altai provide paleoclimatic information for the late Pleistocene in Mongolia, for which only a few sufficiently studied archives exist. Glacial stages referred to global cooling events are reported for the last glacial maximum (27–21 ka) and the late glacial period (18–16 ka). Sedimentary archives from the first part of the last glacial period are infrequent. We present proxy data for this period from two different archives (88–63 and 57–30 ka). Due to the limitation of effective moisture, an increase of precipitation is discussed as one trigger for glacier development in the cold-arid regions of central Asia. Our pollen analysis from periods of high paleolake levels in small catchments indicate that the vegetation was sparse and of dry desert type between 42–29 and 17–11 ka. This apparent contradiction between high lake levels and dry landscape conditions, the latter supported by intensified eolian processes, points to lower temperatures and cooler conditions causing reduced evaporation to be the main trigger for the high lake levels during glacier advances. Rising temperatures that cause melting of glacier and permafrost ice and geomorphological processes play a role in paleolake conditions. Interpreting lake-level changes as regional or global paleoclimate signals requires detailed investigation of geomorphological settings and mountain–basin relationships.

In the present article, we provided grid distribution maps of vascular plants in Mongolia based on a 40  40 km 2 grid cell size. We selected 40 native vascular plant species, belonging to 31 genera and 17 families, which are listed as rare or threatened in Mongolia. With the exception of a few species, the majority of species are also distributed in other Asian countries, including the Asian parts of Russia. Moreover, our focus species are collected as herbarium specimens, and were photographed in their natural habitats during our fi eld surveys. Global and regional distributions, natural habitat, and conservation status of each species are provided in detail.
