Abstract

This study reports new geographical occurrences for seven species of vascular plants (Cyperus michelianus, Gymnocarpium continentale, Rhynchospora alba, Scheuchzeria palustris, Schoenoplectiella supina, Veronica × schmakovii, and V. × sessiliflora), eight species of lichens (Chaenotheca chlorella, Lathagrium dichotomum, Myrionora albidula, Scoliciosporum perpusillum, Physcia alnophila, P. tenella, Peltigera collina, and P. extenuata), and nine species of Lepidoptera in the Altai Territory and the Republic of Altai. For each recorded species, localities and ecological preferences are detailed. Plants Veronica × schmakovii, V. × sessiliflora, and Rhynchospora alba are recorded for the first time in the Altai Territory; Scheuchzeria palustris and Gymnocarpium continentale for the second time. Scheuchzeria palustris and Rhynchospora alba, identified as rare fog-dependent plants, are recommended for inclusion in the Red Book of the Altai Territory. Lichen Chaenotheca chlorella is recorded as a new species for Southern Siberia; Lathagrium dichotomum is recorded for the first time in the Altai Territory; Myrionora albidula, Scoliciosporum perpusillum, Physcia alnophila, and P. extenuata are reported as new lichen species for the Salair Ridge; Physcia tenella and Peltigera collina are new records for the Salair botanical-geographical province within the Altai Territory. New faunistic records for Lepidoptera include first reports for the Altai Territory of the tortricids Cydia medicaginis, Cochylis pallidana, and Aethes cnicana; the chimabachid Dasystoma salicella; the erebids Catocala helena, Catocala bella, and Hypena crassalis; the noctuid Conistra rubiginea; and the lasiocampid Dendrolimus pini. Additionally, the cossid Dyspessa salicicola is reported as a new species for Western Siberia. The sphingids Agrius convolvuli and Macroglossum stellatarum are newly recorded for the Republic of Altai, with the latter's spring discovery suggesting the potential formation of a stable local population. The noctuid Orthosia cerasi is also reported for the first time in the Republic of Altai. Furthermore, this study contributes rare quantitative data on population dynamics, presenting an estimated population size for a newly documented locality of the lichen Lathagrium dichotomum. This information is crucial for conservation planning and assessing the status of this Red Data Book listed species.

Introduction

The present material continues the series of publications on the biodiversity of the Altai Territory and the Republic of Altai (Davydov et al. 2022, 2023; Kosachev and Albach 2022) and represents new records on the distribution of a number of species of vascular plants, lichens, and insects in the Altai Territory and the Republic of Altai, including species requiring special protection. While not all species documented in this study are currently designated for special protection, the identification of new or historically underrepresented populations of rare taxa underscores the critical need for up-to-date distributional data. Accurate and comprehensive information on the geographical spread and ecological preferences of species, particularly those with limited distributions or recognized conservation concern, is fundamental for their effective protection. This knowledge is essential for identifying priority areas for conservation, developing targeted protection strategies, and making informed decisions regarding their inclusion or status within regional and national Red Books. The present work aims to contribute to this vital effort by documenting new occurrences and ecological parameters for some vulnerable species, thereby providing essential evidence for conservation planning and enabling conservation efforts to be more precise and impactful.

Results

Plants

During 2023, significant floristic discoveries were made within the Altai Territory. In a challenging-to-access sector of the Tigirek Nature Reserve (Beloretsk Floristic District), situated in the Belaya River valley, two species belonging to the genus Veronica (V. × sessiliflora and V. × schmakovii) were documented for the first time for the region's flora. Concurrently, the northern part of Altai Territory yielded two additional new species for the regional flora from the family Cyperaceae (Rhynchospora alba and Schoenoplectiella supina). Moreover, analysis of collected specimens and corresponding data from iNaturalist.org revealed the presence of four plant species previously considered rare within the Altai Territory: Gymnocarpium continentale, Scheuchzeria palustris, Cyperus michelianus, and Drosera rotundifolia. Three more new records were discovered during a study of coastal aquatic habitats in the plain part of the Altai Territory.

Note. This is the second record of the species in the region. The first report was made by Silantyeva (2013) for the Pervomaysky District near the village of Bayunovskie Klyuchi on the Klyukvennoye bog. This is a rare plant in Russia, listed in some regional Red Books in the European part (Red Books of Tambov, Lipetsk, Penza, Voronezh, Moscow regions, the Republic of Mordovia and some others) (Red Book... 2019). The limiting factor for the distribution of the species in the southern regions is the limited number of biotopes – sphagnum bogs. Such habitats are typical for more northern regions of Siberia, and in the Altai Territory they are known only in the northern regions. In the Republic of Altai, the plant has also been collected from a site on the Lebed' River (Krasnoborov and Korotkova 1988; Gerasimovich 2012).

Due to the insignificant area of sphagnum bogs and their degradation, the only location of the plant in the region, we recommend a species for inclusion in the Red Book of the Altai Territory.

Rhynchospora alba (L.) Vahl

Material examined. Russia, Altai Territory, Talmensky District, near the village of Vypolzovo, Klyukvennoye Lake, 53°50ʹ11.6ʺ N, 83°46ʹ46.1ʺ E, cranberry-sphagnum bog, 01.vii.2025, leg. P.V. Golyakov (ALTB).

Distribution. This species is widely distributed across the temperate zone of the Northern Hemisphere, with a preference for its southern regions, and is considered a circumpolar bog inhabitant.

Note. This represents the first record of the species in Altai Territory. In Siberia, it grows on Sphagnum or occasionally Hypnum bogs, at the edges of overgrowing lakes, and in waterlogged forests. It is found in eight Siberian regions: Tyumen, Omsk, Tomsk, and Irkutsk regions, Republic of Buryatia, Krasnoyarsk and Trans-Baikal Territories, and Yakutia (Timokhina and Bondareva 1990).

Rhynchospora alba

Schoenoplectiella supina (L.) Lye

Material examined. Russia, Altai Territory, near the city of Barnaul, Obi River floodplain, 53°15′53″ N, 83°52′13″ E, swampy meadow, 06.viii.2024, leg. P.V. Golyakov (ALTB; www.inaturalist.org/observations/234189067).

Distribution. The native range of this species is Europe to Central Siberia and Himalaya, Africa, Brazil to north-east Argentina.

Note. This is the first record of the species in the Altai Territory. It is an annual and grows primarily in the temperate biome. In Siberia, the species is very rare, noted only in two habitats in two provinces: Western Siberia Hemiboreal and Altai-Yenisei Mountain-Hemiboreal (Krasnoyarsk Territory). In addition, as an alien species, the plant is noted in Manchurian Continental province (Shekhovtsova 2024).

Family Droseraceae

Drosera rotundifolia L.

Material examined. Russia, Altai Territory, Talmensky District, near the village of Vypolzovo, Lake Klyukvennoye, 53°50ʹ11.6ʺ N, 83°46ʹ46.1ʺ E, cranberry-sphagnum bog, 01.vii.2025, leg. P.V. Golyakov (ALTB).

Distribution. Occurs in most regions of the Holarctic.

Note. This species is rare in the Altai Territory, with only 11 occurrences previously known in the region (Terekhina and Kopytina 2016). The main habitats of Drosera rotundifolia are acidic bogs and poor fens, although it has also been recorded in intermediate-rich and extreme-rich fens. It predominantly grows in Sphagnum-dominated communities (Baranyai and Joosten 2016). Due to the ongoing degradation of sphagnum bogs in the Altai region, D. rotundifolia faces a threat of extinction within the Altai Territory.

Lichens

Family Collemataceae

Lathagrium dichotomum (With.) Otálora, P.M. Jørg. & Wedin

Material examined. Russia, Altai Territory, Zmeinogorsky District, Tigirek Strict Reserve, Tigirek Range, Belaya River, near Krokhalikha River mouth, on boulder in the water, leg. E.A. Davydov (19442) and Y.V. Storozhenko (TIGZ).

Drosera rotundifolia
Figure 9. Drosera rotundifolia L. P.V. Golyakov, herbarium specimen (ALTB). Photo by P.A. Kosachev.

Distribution. This species exhibits a circumboreal distribution, occurring across Europe, Asia, and North America. Within Russia, it is documented in the Urals (Paukov and Teptina 2012), Eastern and Southern Siberia (Zhurbenko 2000; Makryi 2008; Vershinina et al. 2012; Urbanavicius and Stepanov 2022), and the northern European part, including Karelia (Thüs and Schultz 2009).

Notes. During a survey of approximately 22 km of the Belaya River channel between the tributaries Kazach'ya Slesarka and Strizhanka, only one population of L. dichotomum was observed near the mouth of the Krokhalikha River. The area occupied by this population was approximately 25 dm², estimated to comprise around 250 individuals.

Lathagrium dichotomum has been recently included in the Red Data Book of the Russian Federation (2024); the report for the Altai Territory was based on unpublished data by Yakovchenko and lacked adequate scientific documentation. Here we amend this inaccuracy by providing detailed evidence of L. dichotomum as a new and confirmed record for the Altai Territory.

This is a widespread but infrequently recorded freshwater species. It thrives on permanently inundated siliceous boulders in clear, cold mountain streams, rivers, large creeks, and lakes with relatively slow-moving water (Nimis et al. 2018). It can also rarely occur in the splash zone of watercourses that experience very infrequent drying (Thüs and Schultz 2009).
