Specific instructions

Since the main part of the excursion route passes through remote and sparsely populated areas of Altai, the living conditions in different hotels and tourist centers will vary. We have the opportunity to reserve 2 and 3-bed rooms with standard facilities. The food for the excursion participants will be traditional, but the needs of vegetarians will be taken into account.

The climate of the territory is very diverse. Northern foot-hills are characterized by a moderately warm, humid climate with insignificant differences in day and night temperatures. Average temperatures during the day are +22-25oC, at night - +18-20oC. Short rains are possible. However, participants of the excursion should have waterproof clothing and shoes. The Central and South-Eastern Altai is characterized by a continental and ultra-continental arid climate. Average daily temperatures are +25o- +35oC. Significant precipitation is not expected. Participants should have hats to protect from the sun. When visiting the highlands, moderately low temperatures (+14o - +18oC) are possible. Therefore, it is advisable to have moderately warm clothes.

The Altai is one of the most important biodiversity centers in Northern Eurasia. The wide range of altitudes, climate humidity and continentality result in many zonal vegetation types. We will see the remarkable landscapes of the Katun river valley, Kuraiskaya and Kosh-Agachskaya intermountain basins and the surrounding high mountain ridges.

The main idea of the excursion is to demonstrate the diversity of vegetation in Northern and Central Asia along a geographic transect from the humid lowlands of the Northern Altai to the arid high mountains of the South-Eastern Altai near the border with Mongolia. The length of the path in one direction is about 400 km. Participants of the excursion will be able to see a high diversity of plant communities of four altitude vegetation zones: steppe, forest-steppe, forest, and alpine. Most vegetation types are characterized by high values of species-richness, many plant species are endemics of the Altai and mountains of Southern Siberia. Altai flora contains about 4000 plant species.

More details will be sent to excursion participants directly

Whole day excursion to the ultra-humid foothills of the North-Eastern Altai. Visiting the relic subnemoral small-leaved - dark-coniferous mixed forests of the class Asaro-Abietetea and tall-forb communities of the Mulgedio-Aconitetea.

The Asaro europaei-Abietetea sibiricae have a disjunctive distribution range occupying the foothills of the Altai-Sayan mountain system characterised by locally ultra-humid, weakly continental climate at altitudes of 300-800 m. The link of the Asaro europaei-Abietetea sibiricae forests to the ultra-humid climate explains the main ecological and floristic features of this plant communities: a relatively moderate temperature of the coldest month (January mean: -16oC) and large amount of winter precipitation (275 mm), resulting in the formation of a snow cover of up to 1.5 m that prevents freezing of the soil and protects herbs from damaging impacts of frost. The environments are favorable for species of the European broad-leaved forests (Actaea spicata, Asarum europaeum, Brachypodium sylvaticum, Bromopsis benekenii, Carex sylvatica, Daphne mezereum, Drymochloa sylvatica, Dryopteris filix-mas, Galium odoratum, Lonicera xylosteum, Polystichum braunii, Sanicula europaea, Schenodorus giganteus). These species have disjunctive relic ranges in the Southern Siberia. At the same time the climatic peculiarities support the occurrence of Euro-Siberian and North Asian tall forbs characteristic of subalpine forests. This tall-forb group includes Aconitum lycoctonum, Angelica sylvestris, Bupleurum longifolium, Brunnera sibirica, Parasenecio hastatus, Calamagrostis purpurea subsp. langsdorffii, Cirsium heterophyllum, Delphinium elatum, Euphorbia pilosa, Filipendula ulmaria, Geranium sylvaticum, Lathyrus gmelinii, Lilium martagon, Matteuccia struthiopteris, Milium effusum, Paeonia anomala, Pleurospermum uralense, Senecio nemorensis, Veratrum lobelianum and Saussurea latifolia.

The Mulgedio-Aconitetea tall-forb meadows are characterized by a well-developed herb layer (cover of 85-100 %, height of 80-140 cm (up to 250 cm), species - richness of 25-60 for 100 m2) which is subdivided into several sublayers. The floristic peculiarity is determined by tall-forb species widespread in Europe and West Siberia (Veratrum lobelianum, Rumex alpestris, Delphinium elatum, Viola biflora, Milium effusum, Athyrium distentifolium, Aconitum septentrionale, Bistorta major, Geranium sylvaticum). Besides, there are numerous pairs of close vicarious European and Siberian subalpine and subalpine-forest species: Lathyrus levigatus - L. gmelinii; Lilium martagon - L. pilosiusculum; Solidago virgaurea - S. dahurica; Anemonoides nemorosa - A. altaica; Primula veris - P. pallasii; Erythronium dens-canis - E. sibiricum; Pleurospermum austriacum - P. uralense; Doronicum austriacum - D. altaicum; Bupleurum longifolium - B. aureum; Heracleum sphondylium - H. dissectum; Aconitum napellus - A. baicalense; Stellaria nemorum - S. bungeana. There are European-Siberian species, which are not typical subalpine plants, but they are widespread in European and Siberian tall-forb communities: Thalictrum minus, Anthriscus sylvestris, Polemonium caeruleum, Cacalia hastata. The alliance Cacalio hastatae-Aconition septentrionalis includes tall-forb meadows (sometimes with sparse trees - Abies sibirica, Pinus sibirica, Populus tremula, Betula pendula) of the humid and ultrahumid foot-hills of the Altai. They are closely related to the subnemoral small leaved-dark coniferous mixed forests by natural successions. In the moderately warm ultrahumid meso-climate, the tall-forbs compete successively with the main trees of the Asaro-Abietetea forests (Abies sibirica, Populus tremula, Betula pendula) which have a relatively short period of life (of 70-90 years). These meadows occupy the places where old tree layers were destroyed. Their dense tall-forb layers hinder the development of new generations of trees. The Cacalio hastatae-Aconition septentrionalis meadows are able to exist for a long time before they are replaced by primary forests. As a result, the belt of subnemoral forests in the North Altai represents the combination of the tall-forb meadows and small-leaved coniferous forests. Physiognomically this communities combination is typical of the subalpine landscapes but it is located at the lower altitudes.

The excursion ends at 6 p.m.
Return to the hotel in Gorno-Altaisk.
