    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

    Quercus cerris Quercus cerris in Europe: distribution, habitat, usage and threats D. de Rigo, C. M. Enescu, T. Houston Durrant, G. Caudullo Turkey oak (Quercus cerris L.) is a deciduous tree native to southern Europe and Asia Minor, and a dominant species in the mixed forests of the Mediterranean basin. Turkey oak is a representative of section Cerris, a particular section within the genus Quercus which includes species for which the maturation of acorns occurs in the second year. Quercus cerris L., commonly known as Turkey oak, is a large fast-growing deciduous tree species growing to 40 m tall with 1 Frequency a trunk up to 1.5-2 m diameter , with a well-developed root < 25% system2. It can live for around 120-150 years3. The bark is 25% - 50% 50% - 75% mauve-grey and deeply furrowed with reddish-brown or orange > 75% bark fissures4, 5. Compared with other common oak species, e.g. Chorology Native sessile oak (Quercus petraea) and pedunculate oak (Quercus Introduced robur), the wood is inferior, and only useful for rough work such as shuttering or fuelwood1. The leaves are dark green above and grey-felted underneath6; they are variable in size and shape but are normally 9-12 cm long and 3-5 cm wide, with 7-9 pairs of triangular lobes6. The leaves turn yellow to gold in late autumn and drop off or persist in the crown until the next spring, especially on young trees3. The twigs are long and pubescent, grey or olive-green, with lenticels. The buds, which are concentrated Large shade tree in agricultural area near Altamura (Bari, South Italy).

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.

The next morning early we met our large tour bus and its charming and skillful driver, Grigoris, who hails from the mountain village of Gardiki not far from here. We did a bit of leisurely botanizing before we reached Perdika, our first destination of the day. There are two reasons to visit Perdika: one is the Karavostasi beach, a curving strand with golden sand, and the archaeological site of Dymokastron, a Hellenis- tic mountain-top town reached by a steep hike. The view of the beach far below was beautiful, as it must have been when the town was still inhabited. The town was destroyed in 167 BCE by a Roman army, along with most of the other towns in the vicinity, all allied with Rome’s enemy, Macedonia. The site is under active excavation, and we were able to admire the remnants of protective walls (how in the world did they get those big stones up there?), building foundations, and cisterns, which were certainly needed in case of a prolonged siege, Some members of the IOS Greek tour relaxing under the plane tree in the which Dymocastron must have experienced more than once. village square.

  • Native Tree Rebate Program
    Native Tree Rebate Program The City of Ames has implemented a Smart Watershed Program to increase local awareness of the importance of protecting our local streams and lakes. The program promotes methods to capture, infiltrate, and reduce storm water runoff in residential areas. Planting native trees is one of these methods. What is an Urban Tree Canopy? The canopy of a tree or group of trees is the area of leaves and branches that create shade under the tree(s). Like umbrellas, trees reduce the amount of sunlight and rain reaching the ground. Trees in urban environments are particularly important for intercepting rainfall before it becomes stormwater runoff. Tree leaves, branches, stems, and roots catch falling rain, filter out pollutants, and absorb stormwater. How Can You Determine if Your Property is Suitable for a Tree Planting Project? On Private Property: To give your new tree enough room for healthy growth and to avoid interference with utilities and structures, be sure to plant it: • At least 3 feet from underground utilities, fences, walkways, driveways, decks, and patios. • At least 7 feet from the stems of small trees and shrubs. • At least 10 feet from overhead utilities and trunks of other large trees. • At least 15 feet from structures Within Street Right-of-Way: • Follow the Street Tree Planting Guidelines in this application below What are the Benefits to Property Owners and Communities? • Trees located within 50 feet of a structure can boost property values. • Buildings shaded by trees have lower air conditioning costs and evergreen trees can act as a wind buffer, protecting buildings from heat loss.

    ROOTING STEM CUTTINGS OF SHANTUNG MAPLE (ACER TRUNCATUM), MOUND LAYERING SHANTUNG AND CADDO SUGAR MAPLES (ACER SACCHARUM), AND USING EASTERN REDCEDAR (JUNIPERUS VIRGINIANA) AS A SUBSTRATE COMPONENT IN STEM CUTTING PROPAGATION by JUSTIN ALAN BROCK B.S., Kansas State University, 2013 A THESIS submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Horticulture, Forestry, and Recreation Resources College of Agriculture KANSAS STATE UNIVERSITY Manhattan, Kansas 2014 Approved by: Major Professor Dr. Jason J. Griffin Copyright JUSTIN ALAN BROCK 2014 Abstract Heat and drought tolerance make shantung maple (Acer truncatum) and caddo sugar maple (A. saccharum) good candidates for midwestern landscapes. Improving cutting propagation or mound layering techniques could increase the availability of these species. The influence of time of year, cutting position, and auxin concentration, formulation, and solvent on rooting of stem cuttings of shantung maple was investigated. Semi-hardwood cuttings rooted best (55%). Generally, rooting percentage decreased as indole-3-butyric acid (IBA) concentration increased. Cutting position, auxin formulation, and solvent did not affect rooting. Mean root number and mean root length were unaffected by treatments. Results suggest semi-hardwood cuttings and low IBA concentrations [< 2500 ppm (0.25%)] promote rooting. Auxin concentration influenced rooting of caddo and shantung maple mound layered shoots. Rooting peaked at 15,000 ppm (1.5%) IBA for both caddo (71%) and shantung maples (34%). Mean root number for caddo, but not shantung, increased as IBA concentration increased. Differences in mean root length were not significant. Growers may now propagate caddo maple by mound layering. For shantung maple propagation, stem cuttings are recommended.

Fodor, A. Timofte, T. Geambau Fodor E., Timofte A., Geambau T. 2011. Mycorrhizal status of several Quercus species in Romania (Quercus cerris, Q. frainetto, Q. robur) and the optimization perspective of growth conditions for in vitro propagated plants transplanted in the [ eld. Ann. For. Res. 54(1): 57-71, 2011. Abstract. There is an increasing interest for important tree species conserva- tion in the context of climate change, anthropogenic pressure and invasion of alien tree species. A key factor in the survival of trees is represented by the mycorrhizal association. The success of micropropagated trees also de- pends on the acquisition of mycorrhizal mutualists. Ectomycorrhizal roots samples from several Quercus species (Q. cerris, Q. frainetto, Q. robur) were examined for mycorrhizal morphotypes’ characterization. The sam- ples were collected during the vegetation season from stands located in Southern and North-Western Romania. 30 morphotypes of active mycor- rhizae were identified with Cenococcum geophilum Fr. (Ascomycota) as dominating morphotype. Previous studies on somatic embryogenesis in Q. robur and Q. frainetto demonstrated the utility of in vitro techniques in obtaining plants from these recalcitrant seed producing species, con- sidered at risk in various areas of the country, due to increasingly stress- ful conditions. The success rate of the acclimatization process depends on the mycorrhization performed either artificially, in the laboratory, ei- ther naturally, in the field.
