Forest Steppe Marmot (Marmota kastschenkoi) lives in temperate grasslands across Southeastern Russia. It feeds on grass and roots. Its conservation status is Least Concern.
Fascinating facts about the Forest Steppe Marmot
- The forest-steppe marmot is restricted to a narrow strip of land directly east of the upper Ob River in south-central Russia. Within this range it occupies the wooded forest-steppe zone, preferring habitats that lie between 180 and 450 metres above sea level. This limited distribution means the species is confined to a relatively small region of suitable steppe-forest mosaic. Its presence is tied closely to the specific altitude and vegetation type described.
- Adult forest-steppe marmots measure between 45 and 66 centimetres from head to body, giving them a moderate size for a marmot. After emerging from hibernation in spring they can be as light as 3 kilograms, but by autumn, before the next hibernation, individuals may reach up to 8.9 kilograms as they build fat reserves. This seasonal weight fluctuation reflects the animal's need to store energy for the long underground rest.
- Each year the forest-steppe marmot retreats to its burrow for an extended period of dormancy lasting about six and a half months. The hibernation period begins in August or September, allowing the animal to avoid the harsh winter conditions of its steppe-forest environment. During this time metabolic activity drops dramatically, conserving the fat reserves accumulated in the preceding months. The lengthy underground stay is a defining feature of its life history.
- The forest-steppe marmot population is estimated at roughly fourteen to sixteen thousand individuals. This figure comes from a 2011 survey that found the numbers had remained stable for several decades. Earlier counts had swung both slightly above and markedly below this range, reflecting uncertainty in earlier monitoring. The current stability suggests the species has not suffered major recent declines.
- The forest-steppe marmot was once treated as a subspecies of the gray marmot, but taxonomists now recognise it as a separate species. The key distinction is its diploid chromosome number, which differs from that of M. This genetic difference was sufficient for scientists to split the two despite their similar appearance and overlapping habits.

About the Forest Steppe Marmot
In the undulating hills of the forest steppe, the marmot emerges as a charismatic sentinel, its tawny fur glistening in the sunlight as it stands upright, surveying its domain with an air of quiet confidence. With a fluid motion, it scurries across the grassy expanse, its sturdy legs propelling it with a speed and agility that belies its stout appearance, as it weaves through the landscape with a deep-seated familiarity. As it disappears into the safety of its burrow, the marmot leaves behind a testament to its remarkable resilience, a thriving presence in this delicate ecosystem.
