Sedum thartii L.P. Hebert, a crassulacean plant that originates from Europe, was recently discovered in central Argentina. This species occurs in mountainous habitats in the province of Córdoba; here we show diagnostic characters to aid its identification and ecological features. A key of the species of Sedum in Argentina is also provided.

... least two groups of plants of S. thartii grow in grasslands of Sierras Grandes hills in Córdoba prov- ince, central Argentina, up to the altitude of 1400 m above sea level ( Figure 2A). Periodic visits to locali- ties with the presence of S. thartii showed that the populations are colonizing new places expanding both areally and in number of individuals. ...

... Discussion: This is the only Sedum endemic to Argentina. European Sedum acre L. and Sedum thartii L.P. Hébert (Arana et al. 2014) have been introduced and naturalized in the southern provinces and in Córdoba respectively. Sedum jujuyense is a true South American Sedum very close in appearance to the Peruvian Sedum berillonanum Raymond-Hamet from Ayacucho and Cusco (Pino, 2017) and to Sedum incarum (Ball) Pino (Pino, 2006) from Lima. ...
The succulent endemic species of Crassulaceae in Argentina are reviewed and three new taxa are described. Echeveria argentinensis is a new species already collected 80 years ago in the Quebrada of Humahuaca at Jujuy between 2700 and 3600 m, determined primarily as E. peruviana. Hutchison recognized it as a new species 50 years ago and recorded this epithet in the herbarium sheets, but he never described it. Both species are close and belong to series Racemosae, they share having tuberous roots, but the new species has smaller rosettes and leaves than E. peruviana, a longer stem but smaller scapes and less flowers with erect or adpressed sepals and an opposite petal color pattern, red proximally and yellow distally. Populations from Salta are described as E. argentinensis var. kieslingii. They are smaller, lighter or glaucous in color, leaves are obovate and cuspidate when young, scapes are shorter with less but slightly larger flowers that have a constriction near the middle and are mostly yellow in color. They are distributed along the Quebrada del Toro between 2050 to 2350, in more exposed situations. Also from Salta, but further South, near the border with Tucumán, E. saltensis is described. It resembles E. chiclensis var. cantaensis from Perú, with narrow oblong to linear leaves, in this case with a very interesting multicolored raster on its surface, less tuberous roots, shorter sepals and longer but wider petals, more yellowish than the Peruvian species. This is perhaps the southernmost and lowest growing Echeveria in South America. An extended description of Sedum jujuyense, the only endemic Sedum of Argentina together with some photographs of it are also given.

We evaluated the marking activity of ussuriyskiy wild boar Sus scrofa ussuricus Heude,
1888 and its impact on tree vegetation in the Sikhote-Alin Mountains (1982–2016). 17 species of signal trees were found. Conifers species predominate (90.3%) among the marking objects. Pinus korayensis is the most important species for the wild boar. The average diameter of the marking tree is 31 cm. Three types of marking tags from the nature of infl icted damage are allocated. 9.5% of marking trees shrank in consequence of the marking activity of wild boars. The density of marking objects is 92.1 trees per 1 square km.
Sedum rupestre L. and its close relatives (Sedum series Rupestria) are native to europe. adventive populations in North america were studied both in the field and the herbaria. our results exclude S. rupestre L. and include recognition of two additional taxa on the continent, which are distinguished with keys and illustrations: Sedum forsterianum documented as a naturalized species in the United States, from Washington, and in British Columbia, Canada and Sedum thartii, naturalized in Colorado, Maine, ohio, oregon, Washington and ontario, Canada. A lectotype is established for S. forsterianum.
