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 -

People and Trees: Providing Benefits, Overcoming Impediments
63 PEOPLE AND TREES: PROVIDING BENEFITS, OVERCOMING IMPEDIMENTS Dr Jane Tarran Honorary Associate, University of Technology Sydney Former Senior Lecturer and Course Director, BSc (Urban Ecology) Faculty of Science University of Technology Sydney 1.INTRODUCTION The present paper deals with an area that would be familiar to many in the audience on a daily basis, as they manage trees in urban environments with people. Audience members would also be well aware that it is an area fraught with difficulties, as any community includes people with a vast range of attitudes towards trees. Urban tree management involves managing not just the trees, but also the people, particularly their preferences and expectations, regarding the trees in their community. As our knowledge of tree biology continues to improve, and as we understand more and more about what trees require for establishment and continued healthy growth, we are better placed to know what we should be doing to provide what trees need, even if constraints in the trees' environments often make this difficult. The same cannot be said for our knowledge and understanding of people in relation to trees. Whilst there is an increasing body of research on the benefits to people of ‘green environments’, including trees and other plants, there has been little research to date on people's perceptions of, and attitudes towards, trees. Yet people have a profound impact on the existence and survival of urban trees, and whether or not we can achieve worthwhile and sustainable urban forests. Trees and other plants have the potential to make enormous contributions to the economic, environmental and social sustainability of our human settlements. -

Collection, [Box #, Folder #], Special Collections Research Center, University of Chicago Library. Historical Note For the first years of the University of Chicago, there was considerable ambiguity as to its colors. In 1892, a committee of trustees recommended orange and grey as the university's colors, but only the color orange was officially adopted. However, this decision was far from final. Not only did the use of orange upset Syracuse University, it clashed with University of Chicago students' tradition of using gold as the university color. Complicating this was the use of many different shades of orange and gold in different combination at student events. -
Maples in the Landscape Sheriden Hansen, Jaydee Gunnell, and Andra Emmertson
EXTENSION.USU.EDU Maples in the Landscape Sheriden Hansen, JayDee Gunnell, and Andra Emmertson Introduction Maple trees (Acer sp.) are a common fixture and beautiful addition to Utah landscapes. There are over one hundred species, each with numerous cultivars (cultivated varieties) that are native to both North America and much of Northern Europe. Trees vary in size and shape, from small, almost prostrate forms like certain Japanese maples (Acer palmatum) and shrubby bigtooth maples (Acer grandidentatum) to large and stately shade trees like the Norway maple (Acer platanoides). Tree shape can vary greatly, ranging from upright, columnar, rounded, pyramidal to spreading. Because trees come in a Figure 1. Severe iron chlorosis on maple. Note the range of shapes and sizes, there is almost always a interveinal chlorosis characterized by the yellow leaves spot in a landscape that can be enhanced by the and green veins. Spotting on the leaves is indicative of the addition of a maple. Maples can create a focal point beginning of tissue necrosis from a chronic lack of iron. and ornamental interest in the landscape, providing interesting textures and colors, and of course, shade. some micronutrients, particularly iron, to be less Fall colors typically range from yellow to bright red, available, making it difficult for certain trees to take adding a burst of color to the landscape late in the up needed nutrients.

Shade Tree Info – the Maples
Shade Tree Info – The Maples Acer rubrum is commonly known as Red Maple, or Swamp Maple. Varieties of Acer rubrum offered by Four Seasons include: ‘Autumn Flame’ – one of the first Red Maples to show fall color, Autumn Flame has smaller leaves than most other Red Maples. The branching habit is excellent and the rate of growth is medium. The bright medium-red fall color occurs about 2 weeks earlier than ‘Red Sunset.’ Height x width in 20 years = 30-35’ x 30-35’ ‘Red Sunset’ (A. r. “Franksred’)– has consistently been rated as one of the top 5 shade trees in America since it’s introduction in the mid 1960’s. The clean green leaves turn a fiery orange-red every fall and the symmetrical branching of ‘Red Sunset’ make for a great specimen tree. Height x width in 20 years = 35-40’ x 30-35’ ‘October Glory’ – is the last of the Red Maples to show fall color, with leaves turning deep red about 2 weeks after ‘Red Sunset.’ As with all the rubrum Maples we offer, excellent branching structure and bright light gray bark is a trademark of ‘October Glory.’ Height x width in 20 years = 35-40’ x 30-35’ General notes: Acer rubrum varieties prefer moist soils (remember, they are also known as Swamp Maple) and they require a soil pH below 7. Therefore, rubrum Maples are NOT a good choice for planting in parkways where their roots will wander into the limestone base of a street. But for open lawn areas, they are beautiful trees, and the color they reliably achieve each fall is intense.
