Аннотация: The phenomenon of tree waves (hedges and ribbons) formation within the alpine ecotone in Altai Mountains and its response to observed air temperature increase was considered. At the upper limit of tree growth Siberian pine (Pinus sibirica) forms hedges on windward slopes and ribbons on the leeward ones. Hedges were formed by prevailing winds and oriented along winds direction. Ribbons were formed by snow blowing and accumulating on the leeward slope and perpendicular to the prevailing winds, as well as to the elevation gradient. Hedges were always linked with microtopography features, whereas ribbons were not. Trees are migrating upward by waves and new ribbons and hedges are forming at or near tree line, whereas at lower elevations ribbons and hedges are being transformed into closed forests. Time series of high-resolution satellite scenes (from 1968 to 2010) indicated an upslope shift in the position ribbons averaged 155±26 m (or 3.7 m yr-1) and crown closure increased (about 35%–90%). The hedges advance was limited by poor regeneration establishment and was negligible. Regeneration within the ribbon zone was approximately 2.5 times (5060 vs 2120 ha-1) higher then within the hedges zone. During the last four decades, Siberian pine in both hedges and ribbons strongly increased its growth increment, and recent tree growth rate for 50 year-old trees was about twice higher than those recorded for similarly-aged trees at the beginning of the 20th century. Hedges and ribbons are phenomena that are widespread within the southern and northern Siberian Mountains. © 2017, Science Press, Institute of Mountain Hazards and Environment, CAS and Springer-Verlag Berlin Heidelberg.

Аннотация: Birch (Betula tortuosa) is one of the treeline forming species within the Siberian Mountains. We analysed the area dynamics of birch stands and the upslope climb of birch treeline based on the Landsat time series scenes and on-ground data. We found that since the warming onset (1970(th)) birch area increased by 10%, birch stands and treeline boundary were moving upslope with a rate of 1.4 m/yr and 4.0 m/yr. Birch upslope shift correlated with air temperatures at the beginning (May-June) and the end (August-October) of the growth period. Meanwhile, no correlation was found between birch upslope migration and precipitation. Winds negatively influenced both birch area growth and birch upslope climb during spring, fall, and wintertime. In the windy habitats, birch, together with larch and Siberian pine, formed clusters (hedges) which mitigated the influence of adverse winds. These clusters are the adaptive pattern for trees' upslope climb within windward slopes. The other adaptation to the harsh alpine ecotone habitat is non-leaf (bark) photosynthesis which supports tree survival. Thereby, Betula tortuosa upslope climb depends on the wind impact and warming in spring and fall that extended growth period. With ongoing warming and observed wind speed decrease on the background of sufficient precipitation, it is expected to further birch advance into alpine tundra in the Siberian Mountains.

Аннотация: Проведена инвентаризация зеленых насаждений парка «Гвардейский» Советского района г. Красноярска. Цель работы - оценка видового состава и жизненного состояния древесной и кустарниковой растительности на территории этого парка. Исследование выполнено в летний период 2020 г. Видовое разнообразие, жизненное и санитарное состояние древесно-кустарниковой растительности оценено методом сплошного перечета. Индекс жизненного состояния зеленых насаждений определен с использованием общепринятой методики визуальной оценки древесной и кустарниковой растительности. Установлено, что в парке обитает 38 видов растений (по 19 деревьев и кустарников), относящихся к 30 родам 17 семейств. Растения расположены в виде аллейных и групповых посадок, солитеров, боскетов, а также включены в живые изгороди. Индексы состояния насаждений парка составляют 1,93 для растений в составе аллейных и групповых посадок, солитеров, боскетов, что соответствует ослабленному или слабо поврежденному состоянию; и 1,28 для растений живых изгородей - здоровое насаждение. По итогам исследования определены структура насаждений парка, ее особенности, виды, вносящие в нее основной вклад в количественном отношении. Выявлены наиболее ослабленные виды и причина их ослабления. Из древесных растений в парке ослаблены тополь бальзамический и вяз приземистый, что обусловлено возрастом насаждений. Ослабленное состояние лиственницы сибирской вызвано массовым поражением лиственничной почковой галлицей. Сделан вывод об отсутствии своевременного ухода за растениями, что повлекло ухудшение жизненного состояния многих видов. Определены виды, наиболее устойчивые к неблагоприятным факторам, связанным с произрастанием в условиях города. На основе анализа полученных результатов сформулированы рекомендации по улучшению состояния насаждений парка«Гвардейский».
An inventory of green spaces in the Gvardejskij Park of the Sovetskij District of Krasnoyarsk has been carried out. The aim of the work has been to assess the species composition and vital condition of woody and shrubby vegetation in the territory of this park. The study was carried out in the summer of 2020. The species diversity, vital and sanitary condition of the woody and shrubby vegetation has been assessed by the complete enumeration method. The vitality index of green spaces has been determined using the generally accepted method of visual assessment of woody and shrubby vegetation. It has been established that the park is home to 38 plant species (19 trees and shrubs each) belonging to 30 genera of17 families. The plants are arranged in the form of alley and group plantings, solitaires, bosquets, and are also included in hedges. The vitality index of the park’s plantings is 1.93 for plants in the composition of alley and group plantings, solitaires and bosquets, which corresponds to a weakened or slightly damaged condition, and 1.28 for hedge plants - a healthy planting. Based on the results of the study, the structure of the park’s plantings, its features, and the species that make the main quantitative contribution to it have been determined. The most weakened species and the reason for their weakening have been identified. Of the woody plants in the park, balsam poplar and Siberian elm are weakened, which is due to the age of the plantings. The weakened condition of Siberian larch is caused by massive infestation by larch bud gall midge. The conclusion has been made about the lack of timely care for plants, which has led to deterioration in the vital condition of many species. Species that are most resistant to adverse factors associated with growing in urban conditions have been identified. Based on the analysis of the results obtained, recommendations have been formulated to improve the condition of the plantings of the Gvardejskij Park.
