Some Native Hill Country Trees Other Than Oaks
Some Native Hill Country Trees Other Than Oaks Several weeks ago I wrote about the Hill Country oaks in this column. There are, however a number of common, large, native trees that are not oaks. Here are some of them. Bald cypress ( Taxodium distichum ) is common along the banks of the Guadalupe and its tributaries as well as many other streams in the Hill Country. It is unusual for a conifer (cone-bearing) tree to be deciduous (loses its leaves in the winter) which is why it is called a bald cypress. These trees were highly prized for the durability of the wood for making shingles, which led to the settlement of Kerrville. They are fast growing, and generally the largest trees in the Hill Country. Cedar elm ( Ulmus crassifolia ) is an elm with very small, stiff, rough leaves. It is common throughout the Hill Country where it appears to be equally at home on limestone soils or acidic soils. It flowers and sets seed in late summer, which is unusual, and, because not much is blooming then, it attracts many native bees when flowering. Its leaves turn yellow in the fall. Two other species of elms grow in the Hill Country, although they are not nearly as common as cedar elms. American elm ( Ulmus americana ) and Slippery elm ( Ulmus rubra ) are both large trees with large leaves and are usually found in riparian areas. Escarpment black cherry ( Prunus serotina var. eximia ) is a Hill Country native cherry with thin, soft leaves that turn yellow in the fall. The tiny white flowers are produced on stalks in the spring, followed by tiny cherries for the birds.

Intervascular Pit Membranes with a Torus Was Investigated in Steven Jansen Juvenile Wood Samples of 19 Species of Ulmus and Seven Related Genera

Tori were lacking in diffuse-porous species of Ampelocera, Aphananthe, Gironniera, Holoptelea, Phyllostylon, Trema and Ulmus. • Our observations suggest that tori are more common in cold temperate climates than in warm (sub)tropical environments. This may indicate that narrow tracheary elements with torus-bearing pit membranes provide an auxiliary conducting system which is of low conductivity, but offers greater resistance to freezing-induced cavitation.

City of Carrollton Summary of the Tree Preservation Ordinance (Ordinance 2520, As Amended by Ordinance 2622)
City of Carrollton Summary of the Tree Preservation Ordinance (Ordinance 2520, as amended by Ordinance 2622) A. Application & Exemptions 1. Ordinance applies to all vacant, unplatted or undeveloped property; property to be re- platted or redeveloped, and; public property, whether developed or not. 2. Ordinance does not apply to individual single-family or duplex residential lots after initial development/subdivision, provided that the use of the lot remains single-family or duplex residential. 3. Ordinance does not apply to Section 404 Permits issued by the U.S. Army Corps of Engineers. 4. Routine pruning and maintenance is permitted, provided that it does not damage the health and beauty of the protected tree. B. Protected Trees 1. Only those kinds of trees listed on the Approved Plant List which are 4" in diameter or greater are protected. C. Preservation & Replacement 1. A plan to preserve or replace protected trees must be approved by the City before development or construction, or the removal of any protected tree. The plan must be followed. If no protected trees are present, a letter to that effect, signed by a surveyor, engineer, architect or landscape architect must be submitted to the City. 2. Protected trees to be removed must be replaced. Replacement trees must be chosen from the Approved Plant List, and be of a certain minimum size. Where 12 or more are to be replaced, no more than 34% of the replacement trees may be of the same kind. Replacement trees may be planted off-site, or a fee may be paid to the City instead of replacement, if there is/are no suitable location(s) on the subject property.

Ulmus Alata: Winged Elm1 Edward F
ENH-805 Ulmus alata: Winged Elm1 Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean2 Introduction Usually seen at 45 to 70 feet high, winged elm can reach 90 feet in height in the woods with a 30 to 40-foot spread. Canopy form is variable from pyramidal to vase or rounded. A North American native, this fast-growing deciduous tree is quickly identified by the corky, wing-like projections which appear on opposite sides of twigs and branches. Branches rise through the crown, then bend in a sweeping manner toward the ground. The size of the wings varies greatly from one tree to another. Because it is found growing in wet sites as well as dry, rocky ridges it is a very adaptable tree for urban planting. General Information Scientific name: Ulmus alata Pronunciation: UL-mus uh-LAY-tuh Common name(s): winged elm Family: Ulmaceae USDA hardiness zones: 6A through 9B (Figure 2) Origin: native to the southern two-thirds of the eastern half of the United States UF/IFAS Invasive Assessment Status: Native Uses: street without sidewalk; shade; specimen; parking lot island < 100 sq ft; parking lot island 100-200 sq ft; parking lot island > 200 sq ft; sidewalk cutout (tree pit); tree lawn 3–4 feet wide; tree lawn 4–6 feet wide; tree lawn > 6 ft wide; urban tolerant; highway median; reclamation Figure 1.

Landscape Character Zones and Approved Plants Lists
University of Arkansas Campus Landscape Manual LANDSCAPE CHARACTER ZONES These zones represent the most important organizing principle for any landscape design project. Each character zone defines an expected level of design, supported by an approved plant palette and maintenance level. THREE LANDSCAPE CHARACTER ZONES CAMPUS-WIDE GUIDELINES The campus landscape is organized into three PLANTING DESIGN GUIDELINES character zones with general guidelines and specific plant palettes for each: • Use restrained plant palettes and large swaths of species to provide a background for campus life • Garden Character rather than “showy” displays. • Park Character • Use the approved plant lists for each of the • Natural Character character zones. The intent of the lists is to create These zones support the idea that the character a consitent campus plant palette that celebrates of the campus landscape should vary according signature areas, while also increasing biodiversity, to topography, use, and “importance” within the ecological health, and reducing maintenance campus at large.

Range/Site Description: The most common elm tree in Texas, distributed widely in East, South, and Central Texas. Most often found near streams, in solid stands on atwoods near rivers, or on dry limestone hills. Also planted widely as a landscape tree. Leaf: Alternate, simple, 1" to 2.5" long and 0.75" to 1" wide, oval to elliptical in shape, nely-toothed or sometimes double-toothed along the margin, and blunt at the tip. The upper surface is dark green, shiny, and rough, while the lower surface and petiole are pubescent. Twigs sometimes have thin, corky "wings" and the leaves can turn gold to orange-red in the fall. Flower: Appear in late summer or autumn as hairy, short-stalked clusters in the leaf axils. Fruit: An oval "samara," 0.25" to 0.5" long, the seed centered in the middle of the wing, deeply notched at the tip and hairy all over, especially along the margin. Seeds are borne in the fall, which distinguishes this species from the other native elms. Bark: Light brown to gray, with attened ridges that break into thin, loose, aky scales.
