  • Tree Planting and Management
    COMMONWEALTH WAR GRAVES COMMISSION Tree Planting and Management Breadth of Opportunity The spread of the Commission's responsibilities over some 148 countries in temperate, mediterranean, tropical and desert climates provides wonderful opportunities to experiment with nature's wealth of tree species. We are particularly fortunate in being able to grow many interesting and beautiful trees and we will explain how we manage them and what splendid specimens they can make. Why Plant Trees? Trees are planted for a variety of reasons: their amenity value, leaf shape and size, flowers, fruit, habit, form, bark, landscape value, shelter or screening, backcloth planting, shade, noise and pollution reduction, soil stabilisation and to encourage wild life. Often we plant trees solely for their amenity value. That is, the beauty of the tree itself. This can be from the leaves such as those in Robinia pseudoacacia 'Frisia', the flowers in the tropical tree Tabebuia or Albizia, the crimson stems of the sealing wax palm (Cyrtostachys renda), or the fruit as in Magnolia grandiflora. above: Sealing wax palms at Taiping War Cemetery, Malaysia with insert of the fruit of Magnolia grandiflora Selection Generally speaking the form of the left: The tropical tree Tabebuia tree is very often a major contributing factor and this, together with a sound knowledge of below: Flowers of the tropical the situation in which the tree is to tree Albizia julibrissin be grown, guides the decision to the best choice of species. Exposure is a major limitation to the free choice of species in northern Europe especially and trees such as Sorbus, Betula, Tilia, Fraxinus, Crataegus and fastigiate yews play an important role in any landscape design where the elements are seriously against a wider selection.

Aronia Medik. (chokeberry, Rosaceae) is a genus of woody shrubs with two or three North American species. Species boundaries and relationships between species of Aronia are frequently under question. The only European species in the genus, A. mitschurinii A.K.Skvortsov & Maitul., is suggested to be an inter-generic hybrid. In order to clarify the relationships between species of Aronia, we performed several morphometric and molecular analyses and found that the molecular and morphological diversity within data on American Aronia is low, and species boundaries are mostly not clearly expressed. Whereas morphology is able to separate American species from A. mitschurinii, there is no support for such discrimination from the molecular data; our analyses did not reveal evidence of A.

Sorbus aucuparia occurs on acid, dry to moist and mesotrophic to oligotrophic soils. The species often grows in secondary forests together with Alnus viridis, Sambucus racemosa, Betula pendula, Frangula alnus and some Salix spp. In most climax forests mountain ash grows only in the shrub layer. In the subalpine belt, the tree is present in green alder scrub and European larch-Swiss stone pine forests. On some N-exposed mountain slopes of the S-Alps, small mountain ash forests with green alder build the upper forest limit above 1500 m. In this study, ecological and phytosociological aspects of this particular forest community along a N-S-transect from the Swiss Central Alps (Grisons) to the South Alps (Ticino/ N-Italy) were investigated. We consider site conditions, local spread, rejuvenation, tree age structure, infestation and phytosociological aspects of S.

  • Landscaping with Native Plants in Snoqualmie
    LANDSCAPING WITH NATIVE PLANTS LANDSCAPING WITH NATIVE PLANTS Washington state is home to thousands of plants, many of which can beautify your yard while providing numerous benefits to wildlife, humans, and ecosystems. Sword fern — Polystichum munitum Nootka rose — Rosa nutkana Western trillium — Trillium ovatum Native plants are great for a home gardener because they are adapted to our region’s wet winters and dry summers. This means that, once established, they are easier to manage and require less water. They are also more pest and disease resistant. Gardens with native plants are great for local forests. They provide habitat and foraging opportunities for birds, pollinators, and other wildlife, increasing and improving habitat corridors. Native plants control erosion and reduce pollution and runoff, benefiting both people and wildlife. Some nursery plants, though beautiful, can escape backyard gardens and become invasive weeds in forests. Invasive plants diminish habitats and ecosystems and are a constant battle for land managers. When you garden with native plants, you eliminate this risk of nonnative plants naturalizing in our local forests. Gardening with native plants protects Snoqualmie’s forests and increases our connection to our Ivy — Hedera helix, a popular landscaping plant can beautiful region. escape and become a big problem in forested areas. [email protected] | www.greensnoqualmie.org GENERAL TIPS FOR PLANTING WITH NATIVE PLANTS • Snoqualmie has shallow soils so it is important to use lots of arborist mulch or chips (ground-up tree material) to fortify the soil. Chipdrop.com provides free wood chips. • Give conifers room to grow. Plant away from structures and power lines and anticipate how large your tree will grow.

However, their capacity to provide pollination seems to be quite low, although reports from in-situ research supporting this view are scarce. Our goal was therefore to thoroughly assess their pollination potential based on multifaceted field measurements. For this, we selected six test sites with well-developed riparian hardwood forests, located in the agricultural landscape along the middle Vistula River in Poland. We used seven indicators relating to habitat suitability (nesting sites and floral resources) and pollinator abundance (bumblebees and other Apoidea) and propose a threshold value (AdjMax) based on value distribution and Hampel’s Citation: Affek, A.N.; Regulska, E.; test to indicate the level of pollination potential for this type of riparian forest.

  • European-Mountain-Ash.Pdf
    Weed of the Week European Mountain Ash Sorbus aucuparia L. Common Names: European mountain ash, rowan Native Origin: Originally from most of Europe, northern Africa, and western Asia Description: A deciduous tree in the rose family (Rosaceae) that reaches heights of 25 to 30 feet and widths of 15 to 25 feet . The main trunk is often short, becoming multi-branched and the crown is initially elliptical but becomes wider with age. Bark is light grayish brown, generally smooth with numerous lenticels when young. Cracks, splits and scaly patches develop on older trunks. Leaves are alternate, pinnately compound, and 5" to 9" long. Individual leaflets are serrated on their upper halves, 1 to 1.5 inches long, dull dark green above and paler green below. In fall, leaf color is red to yellow, although sometimes leaves simply drop green. Showy clusters of small white flowers appear in late spring to early summer. Small, orange-red fruits, 3/8 inch in diameter are born in terminal clusters that ripen in fall. Fruits are usually eaten by birds and often do not persist on the tree into the winter. Seeds germinate quite readily in the landscape. Thousands of seeds are produced per plant per year. Seeds have a strong innate dormancy that lifts gradually over a few years. The seeds remain viable in the soil for five years or more. Birds consume the fruits in the fall and helped spread it. Habitat: It favors cool to cold climates, full sun, and well-drained, loamy acidic soils. Trees can grow in urban areas where air pollution, poor drainage, compacted soil, and/or drought are common.

However, the impact of tree species interaction on forest vulnerability to drought is not yet clear. This study aims to assess how deciduous saplings react to drought and whether tree species diversity can buffer the impact of drought stress on tree saplings. Based on field measurements of crown defoliation and species diversity, vulnerability, drought recovery, and species interaction were analyzed. Fieldwork was carried out in Central Eastern Germany in 2018 during the vegetation season and repeated in 2019. Ten random saplings were measured in each of the 218 plots (15 15 m) with 2051 saplings in total × out of 41 tree species. We found that 65% of the saplings experienced defoliation during the drought of 2018, of which up to 13% showed complete defoliation. At the species level, Fagus sylvatica L. and Betula pendula Roth.

  • Sorbus Aucuparia
    Sorbus aucuparia Sorbus aucuparia in Europe: distribution, habitat, usage and threats M. Räty, G. Caudullo, D. de Rigo The rowan or mountain ash (Sorbus aucuparia L.) is a widely spread deciduous tree species, which is only missing from the southernmost parts of Europe and large islands. It can survive in various growing conditions, but in poorer conditions it remains as a bush. A rowan can reach a height of 15-20 metres. It is known for its red fruit which is an important food source for birds particularly during the winter. Rowan and its varieties are popular planted trees in gardens and cities. A changing climate has already enhanced its spread to higher altitudes and further to the north, but in future it is expected to lose its presence in south, central and eastern Europe. The rowan (Sorbus aucuparia L.) is a slender deciduous tree that can reach a height of 15-20 metres on good growing sites, Frequency but may remain a bush on poorer sites1-3.

  • Heavy Metals Uptake by the Hybrid Aspen and Rowan-Tree Clones
    JOURNAL OF FOREST SCIENCE, 53, 2007 (11): 491–497 Heavy metals uptake by the hybrid aspen and rowan-tree clones J. Malá1, P. Máchová1, H. Cvrčková1, T. Vaněk2 1Forestry and Game Management Research Institute, Jíloviště-Strnady, Czech Republic 2Institute of Experimental Botany Academy of Sciences of the Czech Republic, Prague, Czech Republic ABSTRACT: Micropropagated plantlets derived from selected clones of the hybrid aspen (Populus tremula × Populus tremuloides) and the rowan-tree (Sorbus aucuparia L.) were used to determine the comparative study of uptake of the toxic, heavy metals Cd, Pb and the essential metal Mn. Samples of roots and aboveground parts (hypocotyl-derived tissues, leaves and stems) were taken from the plantlets grown for 24, 48, 96, or 168 hrs under aseptic conditions, in hydroponics with the toxic heavy metal and the essential metal salts. The concentration and distribution of the accu- mulated metals were determined using the ICP-OES method. The differences in the uptake capacity of hybrid aspen and rowan-tree clones for Cd, Pb and Mn were identified. Generally, the amounts of accumulated Cd and particularly Pb were much higher in the roots of both hybrid aspen and rowan-tree clones, than in their shoots, at all sample times. Conversely, the amounts of accumulated Mn were significantly lower than Cd and Pb in all plant parts of the hybrid aspen and rowan-tree samples. Patterns of Mn uptake were similar in the above-mentioned tissues of both clones, at all sample times. We concluded that the two clones of hybrid aspen and rowan-tree, lacking auxiliary soil microbiota, can accumulate large amounts of the toxic heavy metals Cd (800–1,500 mg/kg) and Pb (5,000–13,000 mg/kg) in roots and about 100 mg/kg of Cd was determined in aboveground part of hybrid aspen.
