Aromatic Aster an Emphasis on Saving Bees 2019 GREATPLANTS GARDENER NEBRASKA STATEWIDE ARBORETUM “ We plant Nebrasks for healthy homes, vibrant communities and a resilient environment. A Focus on Mother Nature— from Me to She Bob Henrickson, GreatPlants® Coordinator What do gardeners want? A stronger connection with nature, according to the 2019 Garden Trends Report. The trend is a movement from the Me to the She gen- eration, with a focus on Mother Nature. The strongest motivation to save the natu- ral world is to love it; and with our own fate so closely tied to our environment, caring for it in turn nurtures ourselves. Another trend is gardeners’ recognition of the “thinning of the insect world.” Recent years have seen Aromatic Aster an emphasis on saving bees. In coming years we need to extend that care to all Perennial of the Year beneficial insects by planting more natives that provide the pollen and nectar native Symphyotrichum insects rely on.

Another hopeful sign is that more than a fourth of 18-34 year olds are volunteering, higher than the national average. We do have some habits to break— overzealous mowing, manicuring and overmanagement of our landscapes. Our landscapes need less lawn monoculture and more beneficial diversity, for ourselves as well as all the creatures who depend on them. We have other habits to break as well. Nearly 90 percent of adults spend over 22 hours a day inside or in vehicles and most children spend less than an hour a day outside, half as much as their parents did when they were young. Gardening has a lot to offer at every age; it teaches responsibility, healthy choices, patience, trust, confidence, stewardship and delayed gratification. With a third of our food wasted annually, the simple act of composting (which can be as easy as digging a hole or throwing it under shrubs) can reduce household waste by almost 40 percent. What else can we do? We hope gardeners will move toward more prairie- style landscapes and toward less-managed woodland gardens.

  • Oak Diversity and Ecology on the Island of Martha's Vineyard
    Oak Diversity and Ecology on the Island of Martha’s Vineyard Timothy M. Boland, Executive Director, The Polly Hill Arboretum, West Tisbury, MA 02575 USA Martha’s Vineyard is many things: a place of magical beauty, a historical landscape, an environmental habitat, a summer vacation spot, a year-round home. The island has witnessed wide-scale deforestation several times since its settlement by Europeans in 1602; yet, remarkably, existing habitats rich in biodiversity speak to the resiliency of nature. In fact, despite repeated disturbances, both anthropogenic and natural (hurricanes and fire), the island supports the rarest ecosystem (sand plain) found in Massachusetts (Barbour, H., Simmons, T, Swain, P, and Woolsey, H. 1998). In particular, the scrub oak (Quercus ilicifolia Wangenh.) dominates frost bottoms and outwash plains sustaining globally rare lepidopteron species, and formerly supported the existence of an extinct ground-dwelling bird, a lesson for future generations on the importance of habitat preservation. European Settlement and Early Land Transformation In 1602 the British merchant sailor Bartholomew Gosnold arrived in North America having made the six-week boat journey from Falmouth, England. Landing on the nearby mainland the crew found abundant codfish and Gosnold named the land Cape Cod. Further exploration of the chain of nearby islands immediately southwest of Cape Cod included a brief stopover on Cuttyhunk Island, also named by Gosnold. The principle mission was to map and explore the region and it included a dedicated effort to procure the roots of sassafras (Sassafras albidum (Nutt.) Nees) which were believed at the time to be medicinally valuable (Banks, 1917).

  • Oaks (Quercus Spp.): a Brief History
    Publication WSFNR-20-25A April 2020 Oaks (Quercus spp.): A Brief History Dr. Kim D. Coder, Professor of Tree Biology & Health Care / University Hill Fellow University of Georgia Warnell School of Forestry & Natural Resources Quercus (oak) is the largest tree genus in temperate and sub-tropical areas of the Northern Hemisphere with an extensive distribution. (Denk et.al. 2010) Oaks are the most dominant trees of North America both in species number and biomass. (Hipp et.al. 2018) The three North America oak groups (white, red / black, and golden-cup) represent roughly 60% (~255) of the ~435 species within the Quercus genus worldwide. (Hipp et.al. 2018; McVay et.al. 2017a) Oak group development over time helped determine current species, and can suggest relationships which foster hybridization. The red / black and white oaks developed during a warm phase in global climate at high latitudes in what today is the boreal forest zone. From this northern location, both oak groups spread together southward across the continent splitting into a large eastern United States pathway, and much smaller western and far western paths. Both species groups spread into the eastern United States, then southward, and continued into Mexico and Central America as far as Columbia. (Hipp et.al. 2018) Today, Mexico is considered the world center of oak diversity. (Hipp et.al. 2018) Figure 1 shows genus, sub-genus and sections of Quercus (oak). History of Oak Species Groups Oaks developed under much different climates and environments than today. By examining how oaks developed and diversified into small, closely related groups, the native set of Georgia oak species can be better appreciated and understood in how they are related, share gene sets, or hybridize.

  • 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 .

  • The Distribution of the Genus Quercus in Illinois: an Update
    Transactions of the Illinois State Academy of Science received 3/19/02 (2002), Volume 95, #4, pp. 261-284 accepted 6/23/02 The Distribution of the Genus Quercus in Illinois: An Update Nick A. Stoynoff Glenbard East High School Lombard, IL 60148 William J. Hess The Morton Arboretum Lisle, IL 60532 ABSTRACT This paper updates the distribution of members of the black oak [section Lobatae] and white oak [section Quercus] groups native to Illinois. In addition a brief discussion of Illinois’ spontaneously occurring hybrid oaks is presented. The findings reported are based on personal collections, herbarium specimens, and published documents. INTRODUCTION The genus Quercus is well known in Illinois. Although some taxa are widespread, a few have a limited distribution. Three species are of “special concern” and are listed as either threatened (Quercus phellos L., willow oak; Quercus montana Willd., rock chestnut oak) or endangered (Quercus texana Buckl., Nuttall’s oak) [Illinois Endangered Species Pro- tection Board 1999]. The Illinois Natural History Survey has dedicated a portion of its website [www.INHS.uiuc.edu] to the species of Quercus in Illinois. A discussion of all oaks from North America is available online from the Flora of North America Associa- tion [http://hua.huh.harvard.edu/FNA/] and in print [Jensen 1997, Nixon 1997, Nixon and Muller 1997]. The National Plant Data Center maintains an extensive online database [http://plants.usda.gov] documenting information on plants in the United States and its territories. Extensive oak data are available there [U.S.D.A. 2001]. During the last 40 years the number of native oak species recognized for Illinois by vari- ous floristic authors has varied little [Tables 1 & 2].

  • Terrestrial & Palustrine Plant Communities of Pennsylvania 2Nd
    Terrestrial & Palustrine Plant Communities of Pennsylvania 2nd Ed. Section 3 Terrestrial Communities Serpentine pitch pine - oak forest This community type is part of the "Serpentine barrens complex." It occurs in areas underlain by serpentine bedrock where soil development has proceeded far enough to support forest vegetation, but not so far as to override the influence of serpentine chemistry on species composition. Fire is an important factor in the establishment and persistence of pitch pine. In the absence of fire, pine is likely to decrease in favor of hardwood species. Characteristic overstory species include Quercus stellata (post oak), Q. marilandica (blackjack oak), Pinus rigida (pitch pine), Sassafras albidum (sassafras), Juniperus virginiana (red-cedar), Nyssa sylvatica (black-gum), Populus grandidentata (large-toothed aspen), and Robinia pseudoacacia (black locust)—which is generally invasive in these systems. The shrub layer is often dominated by an impenetrable tangle of Smilax rotundifolia (greenbrier) and S. glauca (catbrier). Q. prinoides (chinquapin oak) occurs in the understory and in openings; Quercus ilicifolia (scrub oak) is also present in openings. Low shrub species include Vaccinium pallidum (lowbush blueberry), V. stamineum (deerberry), and Gaylussacia baccata (black huckleberry). Herbaceous species include Pteridium aquilinum (bracken fern), Aralia nudicaulis (wild sarsaparilla), and a variety of graminoids. Related types: The "Serpentine Virginia pine - oak forest" type also occurs on serpentinite-derived soils and shares many species with this type. The Virginia pine type is dominated by a mixture of Pinus virginiana and various oaks. P. virginiana produces denser shade and thicker litter than does P. rigida. Herbaceous and shrub growth under P. virginiana is generally sparse.

  • Hybrid Oaks (Quercus Spp.) of Georgia K.D
    Hybrid Oaks (Quercus spp.) of Georgia K.D. Coder Publication WSFNR-20-26A April 2020 Hybrid Oaks (Quercus spp.) of Georgia Dr. Kim D. Coder, Professor of Tree Biology & Health Care / University Hill Fellow University of Georgia Warnell School of Forestry & Natural Resources The native oaks of Georgia are many and varied. Each has the capacity to interbreed or hybridize with surrounding oak species which are close relatives. Georgia’s hybrid oaks can be difficult to identify due to much gene sharing, cross-breeding, and associated variable leaf and acorn appearance. This publication helps professionals appreciate and understand oak hybrids in Georgia. Oak Hybrids -- A Success Strategy One means of oak genetic variation is generated by hybridization, leading to population divergence and specialization. Hybridization occurs naturally and can evolve into stable, genetically distinct populations and even species. Hybridization can generate new combinations of adaptations, by transferring or combining phenotypic features. (Niklas 2016) Hybridization of oaks played a significant role in their evolution. (Petit et.al. 2003) In addition to oak appearance and form, hybridization has also provided resistance-sharing among oak species to combat pathogens. (Hauser et.al. 2017) Oaks have been long known to exchange gene sets across species boundaries through hybridization and backcrossing. (Crowl et.al. 2019) Introgression is backcrossing with the parent species, and can generate some level of fixation of gene sets and physical features. (Niklas 2016) Hybridization and introgression events in oaks have occurred often, and has helped to solidify traits and adaptations. (Crowl et.al. 2019) Closely related oaks with similar reproductive strategies and overlapping geographical ranges often hybridize naturally.
