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 -
Clonality and Dynamics of Leaf Abscission of Gambel Oaks at Small Spatial Scales in Utah
For. Sci. 61(●):000–000 FUNDAMENTAL RESEARCH http://dx.doi.org/10.5849/forsci.14-204 Copyright © 2015 Society of American Foresters forest ecology Clonality and Dynamics of Leaf Abscission of Gambel Oaks at Small Spatial Scales in Utah Jacob W. Chalmers, Karen E. Mock, Kevin D. Kohl, Katelin J. Madsen, and Nalini M. Nadkarni The Intermountain West of the United States supports a mosaic of Gambel oak (Quercus gambelii Nutt.) clumps interspersed with grassland. Both the tree and shrub forms of Gambel oak are typically found in distinct clumps that have often been presumed to be single clones, although quantitative evidence to support this is minimal. We examined the patterns of clonality within and between oak clumps and explored the variance in phenology of leaf abscission within and among clones and clumps in a study site in the Wasatch Mountains, Utah, USA. Using amplified fragment length polymorphism analysis, we genotyped multiple stems within 10 clumps of Gambel oaks in Red Butte Canyon. Nine of the 10 clumps were monoclonal (each a single distinct genet). The 10th clump was composed of 2 genets. To characterize the genetic influence on leaf abscission phenology, we compared the timing of abscission of individually marked leaves among genets, ramets, and branches. Of these three levels of organization, genet membership had the greatest influence on timing of leaf abscission, and branch membership had the smallest influence. Our results suggest that clonal diversity may be an important metric of phenotypic and ecological diversity in Gambel oak landscapes. Keywords: genet, ramet, abscission, Gambel oak lant communities often comprise genetic mosaics at multiple trait variances are partitioned among genets (clones) versus ramets spatial scales because species in the communities reproduce (stems). -
The Collection of Oak Trees of Mexico and Central America in Iturraran Botanical Gardens
The Collection of Oak Trees of Mexico and Central America in Iturraran Botanical Gardens Francisco Garin Garcia Iturraran Botanical Gardens, northern Spain [email protected] Overview Iturraran Botanical Gardens occupy 25 hectares of the northern area of Spain’s Pagoeta Natural Park. They extend along the slopes of the Iturraran hill upon the former hay meadows belonging to the farmhouse of the same name, currently the Reception Centre of the Park. The minimum altitude is 130 m above sea level, and the maximum is 220 m. Within its bounds there are indigenous wooded copses of Quercus robur and other non-coniferous species. Annual precipitation ranges from 140 to 160 cm/year. The maximum temperatures can reach 30º C on some days of summer and even during periods of southern winds on isolated days from October to March; the winter minimums fall to -3º C or -5 º C, occasionally registering as low as -7º C. Frosty days are few and they do not last long. It may snow several days each year. Soils are fairly shallow, with a calcareous substratum, but acidified by the abundant rainfall. In general, the pH is neutral due to their action. Collections The first plantations date back to late 1987. There are currently approximately 5,000 different taxa, the majority being trees and shrubs. There are around 3,000 species, including around 300 species from the genus Quercus; 100 of them are from Mexico and Central America.

Bur Oak Quercus Macrocarpa Tree Bark ILLINOIS RANGE
bur oak Quercus macrocarpa Kingdom: Plantae FEATURES Division: Magnoliophyta The deciduous bur oak tree may grow to 120 feet Class: Magnolioposida tall with a trunk diameter of five feet. Its bark is dark Order: Fagales brown or yellow-brown with deep furrows. The bud is rounded or slightly pointed at the tip, yellow- Family: Fagaceae brown to red-brown and hairy. The simple leaves are ILLINOIS STATUS arranged alternately along the stem. The leaf blade is broad at the upper end and coarsely round- common, native toothed. The leaf has five to seven lobes. Each leaf is © Guy Sternberg dark green and smooth or slightly hairy on the upper surface and pale and hairy on the lower surface. The leaf may be 14 inches long and seven inches wide with a one inch leaf stalk. Male and female flowers are separate but located on the same tree. Neither type of flower has petals. Male (staminate) flowers are arranged in drooping catkins, while the female (pistillate) flowers are clustered in a small group. The fruit is a solitary acorn. The dark brown acorn may be ovoid to ellipsoid and up to one and three- quarter inches long. The hairy cup covers half to nearly all of the nut and has a fringe of long scales. BEHAVIORS The bur oak may be found statewide in Illinois. This tree tree grows almost anywhere, from dry ridges to bottomland woods. The bur oak flowers in April and May, about the time that its leaves begin to unfold. ILLINOIS RANGE Its heavy, hard wood is used in making cabinets, for ship building, for fence posts and for fuel. -
Beneficial Trees for Wildlife Forestry and Plant Materials Technical Note
United States Department of Agriculture Natural Resources Conservation Service Technical Note No: TX-PM-16-01 August 2016 Beneficial Trees for Wildlife Forestry and Plant Materials Technical Note Background Trees provide shelter and food sources for a wide array of wildlife. White tail deer browse leaves and twigs along with acorns each fall and winter when other food sources are unavailable. More than 100 animal species eat acorns including rabbits, squirrels, wild hog, and gamebirds (Ober 2014). Songbirds and small mammals consume fruits and seeds. Wood peckers (Melanerpes sp.) and red tailed hawk (Buteo jamaicencis) nest in the cavities of hollow or dead trees (Dickson and Connor 1982). Butterflies, moths, and honeybees use trees as larval hosts, nectar sources, and shelter (Hill and Webster 1995). At right is a map illustrating forest types within the Western Gulf Coastal Plain. The Western Gulf Coastal Plain has a diversity of native hardwoods along with three species of southern pines (longleaf (Pinus palustris), shortleaf (Pinus echinata) and loblolly (Pinus taeda). Important native hardwoods used commercially and for wildlife include mockernut hickory (Carya tomentosa), hackberry (Celtis laevigata), green ash (Fraxinus pennsylvanica), black walnut (Juglans nigra), sweetgum (Liquidambar styraciflua), black tupelo (Nyssa sylvatica), white oak (Quercus alba), southern red oak (Quercus falcata), water oak (Quercus nigra), willow oak (Quercus phellos), shumard oak (Quercus shumardii), post oak (Quercus stellata), bald cypress (Taxodium distichum), and American elm (Ulmus americana) (Diggs 2006). 1 Purpose The purpose of this technical note is to assist conservation planners and land managers by providing basic tree establishment information and a list of beneficial wildlife trees (Table 1) when they are planning wildlife and pollinator habitat in east Texas, western Louisiana, southwestern Arkansas, and southeastern Oklahoma. -
