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. -

Gillette Museum of Arthropod Diversity, Department of Bioagricultural Sciences and Pest Management Colorado State University, Fort Collins, CO 80523 Abstract A list of 1531 species ofLepidoptera is presented, collected over 15 years (1988 to 2002), in eleven southern West Virginia counties. A variety of collecting methods was used, including netting, light attracting, light trapping and pheromone trapping. The specimens were identified by the currently available pictorial sources and determination keys. Many were also sent to specialists for confirmation or identification. The majority of the data was from Kanawha County, reflecting the area of more intensive sampling effort by the senior author. This imbalance of data between Kanawha County and other counties should even out with further sampling of the area. Key Words: Appalachian Mountains, -

Cover Image: Snow and pendant cones on spruce tree (reproduced with permission of Photos.com). Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Foreword When it comes to reproduction, gymnosperms are deeply weird. Cycads and coni- fers have drawn out reproduction: at least 13 genera take over a year from pollina- tion to fertilization. Since they don’t apparently have any selection mechanism by which to discriminate among pollen tubes prior to fertilization, it is natural to won- der why such a delay in reproduction is necessary. Claire Williams’ book celebrates such oddities of conifer reproduction. She has written a book that turns the context of many of these reproductive quirks into deeper questions concerning evolution. The origins of some of these questions can be traced back Wilhelm Hofmeister’s 1851 book, which detailed the revolutionary idea of alternation of generations. -
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. -

Cedrus Atlantica 'Glauca'
Fact Sheet ST-133 November 1993 Cedrus atlantica ‘Glauca’ Blue Atlas Cedar1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION A handsome evergreen with blue, bluish-green or light green foliage, ‘Glauca’ Atlas Cedar is perfect for specimen planting where it can grow without being crowded since the tree looks its best when branches are left on the tree to the ground (Fig. 1). This shows off the wonderful irregular, open pyramidal form with lower branches spreading about half the height. It grows rapidly when young, then slowly, reaching 40 to 60 feet tall by 30 to 40 feet wide. The trunk stays fairly straight with lateral branches nearly horizontal. Allow plenty of room for these trees to spread. They are best located as a lawn specimen away from walks, streets, and sidewalks so branches will not have to be pruned. It looks odd if lower branches are removed. Older trees become flat-topped and are a beautiful sight to behold. GENERAL INFORMATION Scientific name: Cedrus atlantica ‘Glauca’ Pronunciation: SEE-drus at-LAN-tih-kuh Common name(s): Blue Atlas Cedar Family: Pinaceae USDA hardiness zones: 6 through 8 (Fig. 2) Origin: not native to North America Uses: Bonsai; specimen Availability: generally available in many areas within Figure 1.

To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two western North American species, T. heterophylla and T. mertensiana, and a clade of Asian species within which one of the eastern North American species, T. caroliniana, is nested. The other eastern North American species, T. canadensis, is sister to the Asian clade. Tsuga chinensis from Taiwan did not group with T. -
