Department of Planning and Zoning
Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only -
Morphometric Leaf Variation in Oaks (Quercus) of Bolu, Turkey

T. 2003: Morphometric leaf variation in oaks (Quercus) of Bolu, Turkey. — Ann. Bot. Fennici 40: 233–242. Genus Quercus (Fagaceae) has a problematic taxonomy because of widespread hybridization between the infrageneric taxa. The pattern of morphological leaf varia- tion was evaluated for evidence of hybridization in Bolu, Turkey, since previous stud- ies suggested that in oaks leaf morphology is a good indicator of putative hybridiza- tion. Principal components analysis was applied to data sets of leaf characters from fi ve populations to describe variation in leaf morphology. Leaf characters analyzed in this study showed high degrees of variation as a result of hybridization between four taxa (Q. pubescens, Q. virgiliana, Q. petraea and Q. robur) of subgenus Quercus while Q. cerris as a member of subgenus Cerris was clearly separated from the others.

Native Trees of Georgia
1 NATIVE TREES OF GEORGIA By G. Norman Bishop Professor of Forestry George Foster Peabody School of Forestry University of Georgia Currently Named Daniel B. Warnell School of Forest Resources University of Georgia GEORGIA FORESTRY COMMISSION Eleventh Printing - 2001 Revised Edition 2 FOREWARD This manual has been prepared in an effort to give to those interested in the trees of Georgia a means by which they may gain a more intimate knowledge of the tree species. Of about 250 species native to the state, only 92 are described here. These were chosen for their commercial importance, distribution over the state or because of some unusual characteristic. Since the manual is intended primarily for the use of the layman, technical terms have been omitted wherever possible; however, the scientific names of the trees and the families to which they belong, have been included. It might be explained that the species are grouped by families, the name of each occurring at the top of the page over the name of the first member of that family. Also, there is included in the text, a subdivision entitled KEY CHARACTERISTICS, the purpose of which is to give the reader, all in one group, the most outstanding features whereby he may more easily recognize the tree. ACKNOWLEDGEMENTS The author wishes to express his appreciation to the Houghton Mifflin Company, publishers of Sargent’s Manual of the Trees of North America, for permission to use the cuts of all trees appearing in this manual; to B. R. Stogsdill for assistance in arranging the material; to W. -

Quercus Coccinea.Indd
Quercus coccinea (Scarlet Oak) Beech Family (Fagaceae) Introduction: Scarlet oak is a member of the red oak group with lobed leaves and is valued for its ornamental attributes as well as its fi ne wood. It is considered an excellent alternative to the overplanted pin oak because it is beautiful throughout the year and tolerates alkaline soil. Culture: Scarlet oak makes an excellent lawn or park tree. It thrives in full sun and well-drained, acidic soil. This tree is less susceptible to chlorosis problems than pin oak. Potential problems on oaks in general include obscure scale, two-lined chestnut borer, bacterial leaf scorch, oak horn gall and gypsy moth. In addition, as little as 1 inch of fi ll soil can kill an oak. Botanical Characteristics: Additional information: Scarlet oak is appropriately named for its Native habit: Maine south to Florida, west to extraordinary leaf color in early spring and in autumn. Minnesota and Missouri. Its delicate branching pattern combined with nearly black bark and persistent leaves make this an exceptional tree Growth habit: Scarlet oak has a rounded, open even in winter. form at maturity. Although scarlet oak has a predominant tap root, it does have some spreading lateral roots, making the tree Tree size: This oak can attain a height of 70 to easier to transplant than some oaks. It is best to transplant 75 feet and a width of 40 to 50 feet. It can reach a the tree in the fall. The lateral roots may appear above the height of 100 feet in the wild. -

Ulrey, Vegetation Specialist, U.S. Department of the Interior, National Park Service, Blue Ridge Parkway, Asheville, NC 28805. Cover Photos Ecological zones, regions of similar physical conditions and biological potential, are numerous and varied in the Southern Appalachian Mountains and are often typified by plant associations like the red spruce, Fraser fir, and northern hardwoods association found on the slopes of Mt. Mitchell (upper photo) and characteristic of high-elevation ecosystems in the region. Sites within ecological zones may be characterized by geologic formation, landform, aspect, and other physical variables that combine to form environments of varying temperature, moisture, and fertility, which are suitable to support characteristic species and forests, such as this Blue Ridge Parkway forest dominated by chestnut oak and pitch pine with an evergreen understory of mountain laurel (lower photo).

Smart tree selections for communities and landowners Bert Cregg and Robert Schutzki, Michigan State University, Departments of Horticulture and Forestry A smart urban or community landscape has a diverse combination of trees. The devastation caused by exotic pests such as Dutch elm disease, chestnut blight and emerald ash borer has taught us the importance of species diversity in our landscapes. Exotic invasive pests can devastate existing trees because many of these species may not have evolved resistance mechanisms in their native environments. In the recent case of emerald ash borer, white ash and green ash were not resistant to the pest and some communities in Michigan lost up to 20 percent of their tree cover. -
An Updated Infrageneric Classification of the North American Oaks
Article An Updated Infrageneric Classification of the North American Oaks (Quercus Subgenus Quercus): Review of the Contribution of Phylogenomic Data to Biogeography and Species Diversity Paul S. Manos 1,* and Andrew L. Hipp 2 1 Department of Biology, Duke University, 330 Bio Sci Bldg, Durham, NC 27708, USA 2 The Morton Arboretum, Center for Tree Science, 4100 Illinois 53, Lisle, IL 60532, USA; [email protected] * Correspondence: [email protected] Abstract: The oak flora of North America north of Mexico is both phylogenetically diverse and species-rich, including 92 species placed in five sections of subgenus Quercus, the oak clade centered on the Americas. Despite phylogenetic and taxonomic progress on the genus over the past 45 years, classification of species at the subsectional level remains unchanged since the early treatments by WL Trelease, AA Camus, and CH Muller. In recent work, we used a RAD-seq based phylogeny including 250 species sampled from throughout the Americas and Eurasia to reconstruct the timing and biogeography of the North American oak radiation. This work demonstrates that the North American oak flora comprises mostly regional species radiations with limited phylogenetic affinities to Mexican clades, and two sister group connections to Eurasia. Using this framework, we describe the regional patterns of oak diversity within North America and formally classify 62 species into nine major North American subsections within sections Lobatae (the red oaks) and Quercus (the Citation: Manos, P.S.; Hipp, A.L. An Quercus Updated Infrageneric Classification white oaks), the two largest sections of subgenus . We also distill emerging evolutionary and of the North American Oaks (Quercus biogeographic patterns based on the impact of phylogenomic data on the systematics of multiple Subgenus Quercus): Review of the species complexes and instances of hybridization.
