“…The experience got both in the Urals and in other regions shows that both natural and artificial recreational plantings need thinning [7,8] and other targeted silvicultural activities. Thinning, in particular allows to increase the stability of plantations not only by systematic recreational loads but also by a possible forest fire.…”

The distribution of forests by categories of protection is analyzed in accordance with the current normative documents on forest management in the territory of the Russian Federation. It is noted that protective forests are divided into 4 groups of protection categories; each of them includes specific types of protection categories. A considerable number of protection category types involves difficulties in working out the system of silvicultural measures for each of them. It should be noted that special purpose similarities of forest management in a number of protection categories types makes possible to unite them. The rules of wood harvesting, reforestation rules and care of forests rules present only general conception of forest management in protective forests. The standard plantations carrying out one or another protective functions at most, has not yet been worked out till now. As a result when planning and carrying out silvicultural measures experts in the field are forced to take non - standard solutions that infrequently results in disputed situations in work carried out estimation. Besides, maximum effect of measures accomplished is failed to be achieved. As a way to solve the problem it is offered to work out recommendations on zone (subzone) - typologic base in each of the specific protection categories. An increase in the area of protective forests can be achieved through the creation of artificial plantations on disturbed lands and lands that have come out of agricultural use. Thus, the plantations of Sukachev’s larch (Larix Sukaczewii Dyl.) created on the former arable land at the age of 61 have a stock of 740 m3 / ha with an average growth of 12.1 m3 / ha per year. The latter makes it possible to improve the ecological situation in the region and largely solve the problem of carbon dioxide deposition.

Abstract. The purpose is to establish the possibility of using mined brick clay pits for grazing livestock and preparing animal feed. The paper deals with the investigation of the above ground phytomass field layer (Fh) being formed dusing the natural growth of mined brick clay pits. Methodology. Species composition of the projective cover and aboveground phytomass were established on the counting areas of 0.5 × 0.5 sizes evenly spaced on the bottom and slopes of pit. At each of the quarry elements at least 30 registration sites were laid. In addition a similar number of registration sites were laid next to the quarry where clay was not mined. Researches were carried out in the district of pine-birch pre-forest steppe forests of the Trans Urals plain province, the west Siberian plain forest region. Results. It was found that the soil of mined out pits does not contain heavy metal and other chemical elements hazardous to animals. The total aboveground phetomass of Fh at the bottom and slopes of the quarry is 1101.1 and 812.6 kg/ha in absolutely dry, state, respectively. The total projective cover at the bottom of the quarry 3 years after the technical stage of reclamation is 64.7 % and on the slopes 42.5 %. The presence of meadow species in the composition, in particular of legumes family (Vicia cracca L.; V. hybridum L.; V. sativa L.; V. vernus L.; V. sylvatica L.; Trifolium pretense L.; T. lupinaster L.; T. repens L.; T. hybridum L.; T. medium L.; Lathyrus pratensis L.; Melilotu salbus Medikus; M. officinalis L. Pall.; Medicago lupulina L.) indicates a high feed value of FR. Scientific novelty. The transfer of mined out brick clay pits for temporary agricultural use will contribute at the formation of soil on the bottom and slopes of the quarry and ultimately, increase the productivity of future plantations.

Успешная интродукция древесных растений сопровождается их натурализацией – внедрением видов инорайонного происхождения в природные фитоценозы. Примером натурализации древесных интроду- центов на Урале может быть образование популяций Hippophae rhamnoides L. на берегах озера Чебаркуль Челябинской области и в зольных отвалах Рефтинской ГРЭС Свердловской области. Высокая изменчивость однотипных признаков определяет приспособленность вида к меняющимся условиям среды и указывает на ослабление жесткости генотипического контроля, слабую стабилизацию фенотипа и увеличение роли внешних факторов в формировании фенотипического признака.Цель исследований – установление изменчивости плодов и листьев облепихи крушиновидной при на- турализации ценопопуляций облепихи на Южном и Среднем Урале в начале экспансии в 1999 г. и через 20 лет. Методикой работы предусмотрены маршрутное обследование интродукционных популяций облепихи на берегах озера Чебаркуль, золоотвалах Рефтинской ГРЭС и определение уровня изменчивости плодов и листьев форм, образованных при спонтанной гибридизации с начала натурализации облепихи и в на- стоящее время. Уровень изменчивости морфологических признаков оценивался по эмпирической шкале уровней изменчивости С. А. Мамаева. В чебаркульской и рефтинской популяциях преобладают плоды облепихи с овальной, шаровидной и конусовидной формой с желтой, светло-оранжевой, оранжевой, красно-оранжевой окраской. По массе 100 шт. плодов наибольшее хозяйственное значение имеют формы чебаркульской популяции, отобранные в начале расселения облепихи на берегах обмелевшего озера Чебаркуль. Посевом семян от свободного опыления нами получен ряд перспективных форм с массой 100 шт. плодов от 40,9 до 70,2 г. Некоторые чебаркульские формы облепихи не уступают по данному признаку сортам этой культуры. Отбор крупноплодных форм облепихи стал возможен в начале плодоношения чебаркульской облепихи. Натурализация данной культуры происходит за счет микроэволюционных процессов в интродукционных популяциях и формообразования за пределами естественного ареала. The successful introduction of woody plants is accompanied by their naturalization – the introduction of species of foreign origin into natural phytocenoses. The population’s formation of Hippophae rhamnoides L. on the shores of Lake Chebarkul in the Chelyabinsk region and ash dumps of the Reftinskaya SDPP in the Sverdlovsk region can be an example of the naturalization of tree introduced species in the Urals.The high variability of the same type of traits determines the species adaptability to changing environmental conditions and indicates a weakening of the genotypic control rigidity, weak stabilization of the phenotype and an increase in the external factors’ role in the formation of the phenotypic trait.The purpose of the research is to establish the variability of fruits and leaves of sea buckthorn during naturalization of sea buckthorn cenopopulations in the South and Middle Urals at the beginning of expansion in 1999 and 20 years later.The methodology of the work provides for a route survey of the introduction populations of sea buckthorn on the shores of Lake Chebarkul, ash dumps of Reftinskaya SDPP and determination of the level of variability of fruits and leaves of forms formed during spontaneous hybridization from the beginning of naturalization of sea buckthorn and at present time. The level of morphological traits’ variability was assessed using an empirical scale of levels of variability by S.A. Mamaev. In the Chebarkul and Reftinskaya populations sea buckthorn fruits with an oval, spherical and conical shape, with a yellow, light orange, orange, red-orange color prevail. By the mass of 100 pieces of fruits, the forms of the Chebarkul population, selected at the beginning of the resettlement of sea buckthorn on the shores of the shallow lake Chebarkul, are of the greatest economic importance. By sowing seeds from free pollination, we obtained a number of perspective forms with a mass of 100 fruits from 40.9 g to 70.2 g. Some Chebarkul forms of sea buckthorn are not inferior to the varieties of this crop in this respect. Selection of large-fruited forms of sea buckthorn became possible at the beginning of fruiting of the Chebarkul sea buckthorn. Naturalization of this culture occurs due to microevolutionary processes in introduction populations and morphogenesis outside the natural area.
