Implications for forest diversity Abstract An increasing demand for forest-based products calls for further development and intensification of forest management. The use of non-native tree species in forestry is a common and expanding silvicultural practice worldwide but the effect of non-native trees on native biodiversity and ecosystem functioning is still poorly understood. The general aim of this thesis is to increase our knowledge about what effects large-scale introduction of a non-native tree species have on forest biodiversity over a chronosequence of forest stand ages. The non-native Pinus contorta and the two native tree species Pinus sylvestris and Picea abies were studied over three age classes (15, 30, 85 years old) of managed forests in northern Sweden to compare the stand- and tree structures, the cover and composition of functional groups of ground vegetation, and the species- and functional diversity of epiphytic lichens. Differences in ground vegetation cover were linked to both tree species and different stand and tree characteristics, but the differences were not consistent over the age classes. -

Connon Nurseries Taylor's Sunburst Lodgepole Pine
Taylor's Sunburst Lodgepole Pine Pinus contorta 'Taylor's Sunburst' Height: 15 feet Spread: 10 feet Sunlight: Hardiness Zone: 4a Description: Wow! When you see this pine tree, you want it - the bright yellow-gold new growth contrasts stunningly with the older green needles for nearly two months in spring, then come the bright red cones; this plant is certain to turn heads in your landscape Ornamental Features Taylor's Sunburst Lodgepole Pine foliage Taylor's Sunburst Lodgepole Pine has attractive green foliage which Photo courtesy of NetPS Plant Finder emerges yellow in spring. The needles are highly ornamental and remain green throughout the winter. The red fruits are held in cones in mid summer. The flowers are not ornamentally significant. The shaggy brick red bark adds an interesting dimension to the landscape. Landscape Attributes Taylor's Sunburst Lodgepole Pine is a multi-stemmed evergreen shrub with an upright spreading habit of growth. Its average texture blends into the landscape, but can be balanced by one or two finer or coarser trees or shrubs for an effective composition. This is a relatively low maintenance shrub. When pruning is necessary, it is recommended to only trim back the new growth of the current season, other than to remove any dieback. It has no significant negative characteristics. Taylor's Sunburst Lodgepole Pine is recommended for the following landscape applications; - Accent - Vertical Accent - General Garden Use Planting & Growing Taylor's Sunburst Lodgepole Pine will grow to be about 15 feet tall at maturity, with a spread of 10 feet. It has a low canopy, and is suitable for planting under power lines. -

Ponderosa Pine
Ponderosa Pine Ponderosa Pine Its dry and spacious groves invite you to camp among them. Its shade is never too thin and never too dense. Its great boles and boughs frame many of the grandest views, of snow-capped cones, Indian-faced cliffs, nostalgic mesas, and all that bring the world to the West's wide door.... If you have been long away from the sound of the Western Yellow Pine, you may, when at last you hear it again, close your eyes and simply listen, with what deep satisfaction you cannot explain, to the whispered plain-song of this elemental congregation. - Donald Culross Peattie Ponderosa pine is one of the best-known trees of the American West, and covers a larger area than any other American conifer. Ponderosa grows from Mexico to British Columbia, and from the Pacific Coast to South Dakota. In the southern Rockies it grows in sunny and fairly dry locations at 5500 to 8000 feet (1680 to 2400 m) elevation, and occasionally to 10,000 feet (3050 m) elevation. Ponderosa pine can endure drought and high temperatures, suiting it to locations where many other kinds of conifers could not survive, including south-facing and west-facing slopes. In such cases it has a stout and rounded form. In a very dry setting a Ponderosa 10 inches (25 cm) thick may be 120 years old. Ponderosa has the longest needle of all types of conifer trees in the southern Rockies, and the needles make a musical sighing when the wind blows. On warm summer days the resin in bark and twigs gives forth a delightful odor. -
