Since the mid-2000s, long-term monitoring of various components of natural ecosystems under conditions of industrial pollution has been carried out in the Southern Urals. As a part of these monitoring programmes, the data on various components of biota in different biotopes, collected with different methods and in different time intervals, continue to be gathered. In addition, data collected through these monitoring programmes can also be used to study the local biodiversity of non-polluted areas. In 2012, in the vicinity of the Karabash Copper Smelter, a study of communities of small mammals was carried out, considering the heterogeneity of their habitats. Within the framework of this project, we presented a detailed description of the state of woody vegetation in the study area. The dataset (available from the GBIF network at https://www.gbif.org/dataset/61384edd-2d0a-437b-8cf0-ff4d2dfcc0da) includes the results of an assessment of the woody vegetation biomass at seven habitats (pine, birch and floodplain forests, reed swamp, sparse birch stand, marshy meadow and dump of household waste) of areas with different levels of industrial pollution in the vicinities of the Karabash, the Southern Urals. Karabash Copper Smelter (KCS) is one of Russia’s most significant point polluters; the main components of its emissions are heavy metals, dust and sulphur dioxide. Parameters of woody vegetation (diameter at breast height, diameter at root collar level and biomass) were estimated for seven forest elements (forest stand, subcanopy (undergrowth and underwood), half-dead tree of a forest stand and four types of coarse woody debris (downed bole, fragment of downed bole, standing dead tree and stump)) at 41 sampling plots (20 at unpolluted and 21 at polluted areas) and 165 subplots (81 and 84, respectively). The dataset includes 411 sampling events (estimation events of the forest elements at sampling plots and subplots), corresponding to 5786 occurrences (estimations of the woody vegetation components) observed during July 2012. For most woody vegetation components (72%), an estimate of the above-ground phytomass is given. For each sampling event, information on the presence or absence of woody vegetation species at the considered habitats is provided (a total of 1479 occurrences with status "absent"). The dataset can be used for environmental monitoring, sustainable forest management, modelling forest productivity considering global changes, studying the structure and biodiversity of forest cover and assessing forests’ carbon-sequestration capacity. In addition, the dataset provides information about different forest ecosystems under the influence of strong industrial pollution.

Generative Organs

Загрязнение лесов сильно влияет на их биологическую продуктивность, но вклад генеративной сферы в нее изучается редко. Наше исследование биомассы генеративных органов деревьев и древостоев сосны обыкновенной и березы повислой проводилось в течение одного вегетационного периода в градиенте загрязнения от Карабашского медеплавильного завода на Южном Урале. Установлено, что максимальная биомасса генеративных органов сосны и березы на уровне как дерева, так и древостоя, приходится на буферную часть градиента загрязнения, в которой древостой, согласно явлению гистерезиса, переходит из одного устойчивого состояния в другое, и на эту же буферную зону приходится максимальная изменчивость биомассы генеративных органов. Полученная закономерность, общая для двух древесных видов, указывает на повышенную адаптивную реакцию массы генеративной сферы деревьев и древостоев на загрязнение в буферной зоне, и можно предположить, что это отражает хорошо известное явление гормезиса в биологии. Высказанное предположение требует углубленного изучения влияния загрязнения на генеративную сферу лесных сообществ. Forest pollution strongly affects their biological productivity, but the contribution of the generative sphere to it is rarely studied. Our study of the biomass of generative organs of trees and stands of Scots pine and drooping birch was performed during one growing season in the pollution gradient from the Karabash copper smelting plant in the southern Urals. It is stated the maximum biomass of generative organs of pine and birch at the level of both a tree and a stand, falls on the buffer part of the pollution gradient, in which the tree stand, according to the phenomenon of hysteresis, passes from one stable state to another one, and the same buffer zone accounts for the maximum variability of the biomass of generative organs. The resulting pattern, common to the two species, indicates an increased adaptive response of trees and stands to pollution in the buffer zone in terms of the mass of the generative sphere and one can suppose it reflects the well known phenomenon of hormesis in biology. This assumption requires in-depth studies of the impact of pollution on the generative sphere of forest communities.

The dataset contains records of small mammals (Eulipotyphla and Rodentia) collected in the background (unpolluted) areas in the vicinity of Karabash copper smelter (Southern Urals, Russia) and the territory of the Sultanovskoye deposit of copper-pyrite ores before the start of its development. Data were collected during the snowless periods in 2007 (18 sampling plots), 2008–2010 (13 plots annually), 2011 (30 plots) and 2012–2014 (19 plots annually). The capture of animals was carried out in different types of forests (pine, birch, mixed and floodplain), sparse birch stands, reed swamps, marshy and dry meadows, border areas, a household waste dump, areas of ruderal vegetation and a temporary camp. Our study of small mammals was conducted using trap lines (snap and live traps). During the study period, 709 specimens of small mammals were caught, which belonged to five species of shrews and 13 species of rodents. The dataset may be highly useful for studying regional fauna and the distribution of species in different habitats and could also be used as reference values for environmental monitoring and conservation activities. Our dataset contains new information on occurrences of small mammals. It includes the peculiarities of their habitat distribution in the background areas in the vicinity of the large copper smelter and the deposit of copper-pyrite ores before the start of its development (Chelyabinsk Oblast, Russia). All occurrence records of 18 mammal species with georeferencing have been published in GBIF.

Within the Western slope of the Southern Urals, there are plenty of basite dyke complexes of Riphean to Vendian among Precambrian terrigenous-carbonate formations. In metamorphic formations of the Taratash complex (Archean to Early Proterozoic, the northern closure of the Bashkirian meganticlinorium) there was observed the andesitic dyke with isotopic age of 71±1 Ma (U-Pb SHRIMP II on zircons) and near Bakal two bodies of gabbroids with zircons of similar ages were found. These are the first evidence of possible Mezozoic magmatism in this region.
