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

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.

These kinds of soils are associated with lands that are periodically inundated, such as broad stream valleys, low-lying fields, and the margins of lakes, ponds, or sloughs. Swamp white oak is not found where flooding is permanent (2,4,5,6,8). In general, the soils on which this oak most commonly is found are in the orders Entisols and Inceptisols. Associated Forest Cover Swamp white oak is a consistent though mostly a minor component of hydromesophytic forest com- munities in which other species usually dominate.

Oaks for the Adelaide Plains: Successful Species in the Waite Arboretum
Treenet Proceedings of the 4 th National Street Tree Symposium: 4 th and 5 th September 2003 ISBN 0-9775084-3-9 Treenet Inc OAKS FOR THE ADELAIDE PLAINS: SUCCESSFUL SPECIES IN THE WAITE ARBORETUM Jennifer Gardner , Waite Arboretum, University of Adelaide, South Australia Abstract The University of Adelaide’s Waite Arboretum is a valuable experimental collection. Species of oaks performing well there under natural rainfall of 625 mm are reported. Most successful are the species from the Mediterranean region, California and Mexico. Many of these oaks have potential for street or amenity planting. Introduction Oaks belong to Quercus, one of eight genera in the family Fagaceae that occurs primarily in temperate Northern Hemisphere. The family also includes sweet chestnuts Castanea (8 spp.), Trigonobalanus (3 spp.), beeches Fagus (10 spp.), Chrysolepis (2 spp.) and two tropical genera Castanopsis (134 spp.) and Lithocarpus (325 spp.) (Govaerts & Frodin, 1998). In Australia the family is represented by the Gondwanan genus Nothofagus (34 spp.) which considered to be in a separate family by Hill & Jordan (1993). Of the 531 species of oaks, about 250 occur in the Americas, 125 in Asia and Malesia and the rest in Europe, N. Africa and Macaronesia (Govaerts & Frodin, 1998). Sierra Madre Occidental, Mexico and East and Southeastern Asia are rich in species. The infrageneric taxonomy of oaks is in a state of flux and various schemes exist. Oaks are widely cultivated, and widespread hybridisation and high variability make the delimitation of some species contentious. The Waite Arboretum The Waite Arboretum is nestled in the foothills of Adelaide, South Australia , 34 o58’S 138 o 38’E at an altitude of 100 – 110m.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Benefits of repeated air-root-pruning of seedlings when stepping up to progressively larger con- tainers include excellent lateral root distribution immediately below the root collar and an excep- tionally fibrous root ball. To evaluate long-term field performance of repeatedly air-root-pruned container stock, three plantings of swamp white oak (Quercus bicolor Willd.) 10 to 13 years old were located that also included bareroot planting stock. Initial and final stem diameter and height and above-ground green weights were determined on randomly selected trees at each site. On a site with a sandy, excessively drained, high pH soil, trees (age 10) from container stock were 1.5 times taller, 2.3 times larger in dbh, and 2.8 times greater in green weight than trees from bareroot stock which averaged only 2.9 m tall, 3.9 cm dbh, and 16.3 kg green weight.
