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 Robur (Fagaceae)
Quercus robur (Fagaceae) The map description EEBIO area The integrated map shows the distribution and changes in the areal’s boundaries of pedunculate oak (Quercus robur). Q. robur is the dominant forest- formative species in the belt of broadleaf and mixed 4 needleleaf-broadleaf forests in the plains of the European part of the former USSR (Sokolov et al. 1977). In the northern part of its areal Q. robur grows in river valleys. In the central part, it forms mixed forests with Picea abies; closer to the south – a belt of broadleaf forests where Q. robur dominates. At the areal’s south boundary it forms small (marginal) forests in ravines and flood-plains (Atlas of Areals and Resources… , 1976). Q. robur belongs to the thermophilic species. The low temperature bound of possible occurrence of oak forests is marked by an average annual of 2?C l (http://www.forest.ru – in Russian).

E-mail: [email protected] Received on June 15, 2016; accepted on February 24, 2017. Description of the subject. Quercus rubra L. is considered an invasive species in several European countries. However, little is known about its dispersal in the introduced range. Objectives. We investigated the significance of animal dispersal of Q. rubra acorns on the ground by vertebrates in its introduced range, and identified the animal species involved. Method. During two consecutive autumns, the removal of acorns from Q. rubra and from a native oak was assessed weekly in forest sites in Belgium. We used automated detection camera traps to identify the animals that removed acorns. Results. Quercus rubra acorns were removed by wood mice (Apodemus sylvaticus L.), red squirrels (Sciurus vulgaris L.), rats (Rattus sp.), and wild boars (Sus scrofa L.). The two former are scatter-hoarding rodents and can be considered potential dispersers. -
Lichens of Red Oak Quercus Rubra in the Forest Environment in the Olsztyn Lake District (NE Poland)
ACTA MYCOLOGICA Dedicated to Professor Alina Skirgiełło Vol. 41 (2): 319-328 on the occasion of her ninety-fifth birthday 2006 Lichens of red oak Quercus rubra in the forest environment in the Olsztyn Lake District (NE Poland) DARIUSZ KUBIAK Department of Mycology, University of Warmia and Mazury in Olsztyn Oczapowskiego 1A, PL-10-957 Olsztyn, [email protected] Kubiak D.: Lichens of red oak Quercus rubra in the forest environment in the Olsztyn Lake District (NE Poland). Acta Mycol. 41 (2): 319-328, 2006. A list of 63 species of lichens and 4 species of lichenicolous fungi recorded on the bark of red oak (Quercus rubra L.) in Poland is given. Literature data and the results of field studies conducted in the forest in the Olsztyn Lake District between 1999 and 2005 are used in the report. Fifty-five taxa, including lichens rare in Poland, for instance Lecanora albella, Lecidella subviridis, Ochrolechia turneri, were recorded. Key words: lichens (lichenized fungi), lichenicolous fungi, red oak (Quercus rubra), Poland INTRODUCTION Rich lichen biotas, usually comprising numerous specific species, are associat- ed with the genus Quercus L. both in Poland (Cieśliński, Tobolewski 1988; Rutkowski 1995) and in other parts of Europe (Alvarez, Carballal 2000; Zedda 2002; Engel et al. 2003). Many rare or very rare lichen species in Poland and taxa considered to be extinct have been found to colonise oak bark in Poland (Cieśliński, Tobolewski 1988; Rutkowski 1995; Rutkowski, Kukwa 2000; Fałtynowicz 1991). Its diversified texture provides niches suitable for dif- ferent lichen species while the phorophyte’s longevity influences the richness and diversity of its lichen biota. -
Quercus Robur and Quercus Petraea
Quercus robur and Quercus petraea Quercus robur and Quercus petraea in Europe: distribution, habitat, usage and threats E. Eaton, G. Caudullo, S. Oliveira, D. de Rigo these oaks can mix, compete and naturally hybridise with other Mediterranean oaks, such as Quercus pubescens and Quercus Quercus robur L., (pedunculate oak) and Quercus petraea (Matt.) Liebl., (sessile oak) are common broadleaved tree frainetto, even if at relatively low rates12. Both oaks occur at species in Europe, found from Scandinavia to the Iberian Peninsula. The two species are quite similar in appearance and higher elevations in southern regions: Q. robur is recorded to grow have a broadly overlapping range. Oak trees have cultural significance for people throughout Europe and the trees or up to 1 300 m in the Alps13, while Q. petraea is more montane leaves are frequently used in national or regional symbols. Oak trees can live for more than 1 000 years and grow to and in southern Turkey can reach over 2 000 m4, 14, 15. Due to the be 30 to 40 m in height. The wood from oaks is hard and durable and has been valued for centuries. It is favoured for substantial human interest and usage of the species over many construction and for wine and spirit barrels; historically it was a major source of ship timbers. Recently, concerns have centuries, there is widespread disturbance in their distribution, and arisen about the fate of oaks in the face of Acute Oak Decline, a little understood syndrome. the structure of their original forests is highly uncertain16.

There have been books on the battle to transform the wilderness into an agriculturally ordered land, on the convicts, on the goldrush, on the discovery of the wealth of the continent, on most aspects of settlement, but this is the first to link the story of the discovery of the continent with the slow awareness of its unique trees, shrubs and flowers of Australia. The Flower Chain Chapter 1 The Flower Chain Begins Convict chains are associated with early British settlement of Australia, but there were also lighter chains in those grim days. Chains of flowers and seeds to be grown and classified stretched across the oceans from Botany Bay to Europe, looping back again with plants and seeds of the old world that were to Europeanise the landscape and transform it forever. -

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. -
