About Gross Region

This region includes our Gross and Taborny operating mines, as well as our Tokko project.

The nearest regional protected natural area is Charuoda nature reserve located approximately 10 kilometers from our mine site.

The nearest federal protected areas are the Vitimsky and Olekminsky reserves.

Биоразнообразие

Biodiversity

The South-Siberian Taiga next to our gold producing region is home to

species of vascular plants, moss, and lichen as well as
animal species

Plants

Our gold deposit is located in deciduous woods and woodlands dominated by larch, vaccinium and ledum with a prominent moss and lichen layer. Mountain slopes are home to dwarf pines, alder trees and dwarf birch.

Animals

This area is home to typical taiga animals, such as Siberian chipmunks, sables, stoats, spotted nutcrackers, bramblings, Pallas’s rosefinches and three-toed woodpeckers, as well as tundra dwellers and other more common species, such as viviparous lizards, foxes, common buzzards, and cuckoos.

Biomonitoring

We conduct biological monitoring to evaluate the biodiversity and abundance of plants and animals in the areas surrounding the Gross Region.

Through research, we understand current plant and animal environment, identify vulnerable species, and develop plans to preserve and reintroduce animal populations.

We are conducting a scheduled biodiversity monitoring project at Gross in 2021

Biodiversity research areas

0–100 m
200–400 m
600–1 600 m
2 000–5 000 m

Within each area:

Plant and animal studies are conducted

Even the slightest changes are documented

We monitor populations of species included in Russian Federal and Sakha Red Lists.

We establish monitoring baselines as points of reference for future studies.

Key phases

1Field studies

Research subjects in the Gross area:
Vertebrates: mammals, birds, reptiles, and amphibians
Terrestrial invertebrates
Plankton and benthos
Plants and mushrooms
Area inspection:
  • Animal trail research
  • Soil, and water sampling
  • Identifying key habitats
Compiling descriptions of plants and animals
Photo shooting of species and study progress

2Laboratory processing

Sample analysis:
  • Herbarium definition
  • Evaluation of soil and water samples
  • Animal counting
  • Environmental mapping
Creating lists of protected and vulnerable species
Identifying and establishing key points for future monitoring
Creating lists of plant and animal species

Results

We identify plants and animals resident to the Gross Region, as well as other vulnerable species.
We establish key places for environmental monitoring around the region.
We are developing a detailed environmental action plan to preserve biodiversity in the vicinity of the Gross Region.
Biomonitoring in the Gross area is just one of many steps Nordgold is taking to uphold international standards in environmental protection.
Other things we 
do to preserve the nature
of Southern Yakutia
We replenish the water habitat biodiversity every year by releasing young northern whitefish in Vilyuisk Reservoir in Yakutia
In 2021-2022 we will plant more than 200 hectares of forests in Yakutia
We would like to live in a world full of diverse and fascinating creatures and plants, and to preserve our nature for future generations. This is one of the biggest commitments of our thousands-strong team

Rhododendron aureum
Height:
30-60 cm
Flowers:
golden yellow, 5 cm wide, in clusters
Protection status:
vulnerable
Rhododendron aureum
Evergreen shrub common in mountainous areas of Siberia and the Far East. Grows near the deposit on medium slopes, in rocky areas and in dwarf pine woods 1,100-1,200 meters above sea level. It is an endangered species under protection in Yakutia.
Dwarf pine
Height:
0.5 to 5 meters
Lifespan:
250-300 years
Cones
with edible
seeds
Pinus pumila
A small shrub-like tree with a branchy trunk often squished into the ground.
Grows slowly and can live up to 250-300 years.
Very prominent in the medium and high slopes around the deposit. Its cones are rich in starch and sugar and are a staple food for local animals.
Hericium coralloides
Where can you see it:
these mushrooms usually grow on the same spot in July August every 2-5 years
Fruit body:
12-30 centimeters wide
Protection status:
endangered species
Hericium coralloides
An unusual mushroom that is difficult to confuse with other mushrooms. Its fruit body resembles a coral. It grows on dry tree stumps and fallen deciduous trees.
It is considered edible when young, yet collecting it is not recommended as it is an endangered species included on the Yakutia Red List.
Brown bear (Yakutia bear)
Weight:
up to 150-200 kg
Litter:
2 cubs on average
