Summary: Chris Graves aced Winter Tree ID 2 at Tennessee Urban Forestry Council 2023 Webinar Number 2 Monday, Feb. 13, 2023, 12:00 noon to 1:00 p.m. Eastern Time.

Certified Wildlife Biologist, University of Tennessee Institute of Agriculture J.E. Moss Achievement Awardee and University of Tennessee Senior Lecturer Chris Graves accepts as wide-ranging trees of Tennessee and the other Southern States longleaf (Pinus palustris, from Latin pīnus, “pine tree” and palūs, "bog, swamp" via palūstris, "boggy, marshy, swampy") and shortleaf (Pinus echinata, from Latin pīnus, “pine tree” and echināta, "prickly") pine trees. He acclaimed both in Winter Tree ID 2 for the Tennessee Urban Forestry Council 2023 Webinar series hosted and organized, with assistance from Kevin Bolger of University of Tennessee Institute of Agriculture's (UTIA's) School of Natural Resources, by Katie Donaldson of UTIA's School of Natural Resources and Neil Letson of Tennessee Urban Forestry Council. "Pinus Echinata: Seedling, Male and Female Flower, and Leaf Sections.

Chris Graves aced Winter Tree ID 2, to Part 1 Monday, Jan. 30, 2023, at Tennessee Urban Forestry Council 2023 Webinar Number 2 Monday, Feb. 13, noon to 1:00 p.m. Eastern Time.

University of Tennessee Senior Lecturer Christopher Graves balanced his first-part approach to what winter trees bear with Part 2 baring what landscape bears what tree species. Chestnut oaks (Quercus montana, from Latin quercus, “oak”; montāna, “mountain”), white oak (Leucobalanus, from Greek λευκός, “white” and Latin balanus, “acorn”) group member, claim dry uplands. They display deep-furrowed, orange-striped, tall-ridged bark; angled, bud-clustered, squat buds; 1- to 1.5-inch- (25.4- to 38.1-millimeter-) long, smooth inner-surfaced, smooth-undersided, thick-capped acorns; and bristle-free, wavy-lobed leaves.

Chestnut oak-like environments enable sourwood (Oxydendrum arboretum), with crooked trunk; furrowed, ridged bark; all-red or green- and red-sided twigs with lateral buds and half-circle leaf scars.

Digital, virtual attendees accessed Winter Tree ID 2 Monday, Feb. 13, 2023, between noon and 1:00 p.m. Eastern Time, at the Tennessee Urban Forestry Council 2023 Webinar series hosted and organized, with assistance from Kevin Bolger of University of Tennessee Institute of Agriculture's (UTIA's) School of Natural Resources, by Katie Donaldson of UTIA's School of Natural Resources and Neil Letson of Tennessee Urban Forestry Council. They accompanied Certified Wildlife Biologist, University of Tennessee Institute of Agriculture J.E. Moss Achievement Awardee and University of Tennessee Senior Lecturer Chris Graves on his physiographic (from Greek φύσις, "nature, physical" and γραφή, "description") analyses of 1 Ericaceae (from Greek ἐρείκη, "heath [Erica arborea]" and Latin -āceae, "resembling"), 6 Fagaceae (from Latin fāgus, "beech" and -āceae, "resembling") and 5 Pinaceae (from Latin pīnus, "pine tree" and -āceae, "resembling") family members. They accumulated, from the first analysis, winter bark, bud, acorn and dropped-leaf appearances of chestnut oak (Quercus montana, from Latin quercus, “oak”; montāna, “mountain”), white oak (Leucobalanus, from Greek λευκός, “white” and Latin balanus, “acorn”) group and Fagaceae family member; illustration of Quercus montana captioned as "Quercus Pus. palustris [Q. prinus var. palustris]. Chesnut White Oak," illustrated by French natural history artist Pancrace Bessa (Jan. 1, 1772-June 11, 1846), in F. André Michaux, Histoire des arbres forestiers de l'Amérique septentrionale, tome deux (M.D.CCC.XII [1812]), Plate 7, opposite page 51: Biodiversity Heritage Library (BioDivLibrary), Public Domain, via Flickr

Black oak (Quercus velutina, from Latin vellus, “fleece”) features black outer, orange inner bark; bristle-tipped leaves; clustered, large, velvety buds; angled, stout twigs; shingle-like acorn caps.

Southern red oak (Quercus falcata, from Latin falcāta, “sickle-shaped”) guards black-gray, furrowed bark cracked horizontally; turkey-track-patterned leaves with overturned-bell-patterned bases; 45-degree-angled, lateral buds; flat-scaled acorn caps. Scarlet oak (Quercus coccinea, from Latin coccinus, “scarlet”; -eus, “made of”) has flat, ski-slope-like bark above, blocky bark below breast-height diameter (DBH, 4.5 feet 1.37 meters). It includes red-based, two-clustered, terminal-tip, white-tipped buds; c-shaped leaf scars; and concentric-ringed acorn caps even as its architecture involves old, often blackened and midway up branches.

Northern red oak (Quercus rubra, from Latin rubra, “red”) joined above-mentioned dry-upland dwellers in Winter Tree ID 2 by Chris Graves for Tennessee Urban Forestry Council.

Certified Wildlife Biologist, University of Tennessee Institute of Agriculture J.E. Moss Achievement Awardee and University of Tennessee Senior Lecturer Chris Graves accustomed digital, virtual audiences of his Winter Tree ID 2 analyses to such upland species as black (Quercus velutina), chestnut (Quercus montana), northern red (Quercus rubra), scarlet (Quercus coccinea), southern red (Quercus falcata) and white (Quercus alba) oak trees. His analyses for Tennessee Urban Forestry Council 2023 Webinar series hosted and organized, with assistance from Kevin Bolger of University of Tennessee Institute of Agriculture's (UTIA's) School of Natural Resources, by Katie Donaldson of UTIA's School of Natural Resources and Neil Letson of Tennessee Urban Forestry Council likewise acknowledged sourwood (Oxydendrum arboretum, from Greek ὀξύς, "acid, acute, pungent, sharp" and δένδρον, "tree"; and from Latin arborētum, "arboretum, plantation of trees"), Ericaceae family member and upland-forest associate of chestnut oak; collage of images of Sourwood (Oxydendrum arboreum) taken by Tennessee Valley Authority (TVA) as shoreline (river, land, shore) stabilizers: Public Domain, via Wikimedia Commons

Northern red oak keeps flat-ridged, non-blocky, ski-slope-like bark; deep-sinus leaves variably shaped; black-red, clustered, sharp-pointed, terminal buds; and 1.5-inch- (3.81-centimeter-) long, thin-scaled caps to smooth acorns.

White oak (Quercus alba, from Latin alba, “white”) lodges shaggy-plated, vertical-striped bark; bristle-free, deep-sinused, round-lobed leaves; brown-red, smooth, terminal buds; knobby, 1-inch- (2.54-centimeter-) long acorn caps. Virginia pine (Pinus virginiana, from Latin pīnus, “pine tree” and virginiāna, “Virginian”) manifests crooked trunks; cornflake-sized, scaly, sloughable bark; twisted, two-needle bundles; baseball-sized, scaly, sharp-prickled cones. Shortleaf pine (Pinus echinata, from Latin echināta, “prickly”) nets straight trunks; dome-shaped, self-pruned canopies; plated, resin-pockmarked bark; two-needle fascicles (from Latin fasciculus, “bundlet”); egg-shaped, prickled cones.

Chris Graves offered Tennessee Urban Forestry Council, in Winter Tree ID 2, 2,300- to 3,000-foot (701.04- to 914.4-meter) elevation-occurring Pitch pine (Pinus rigida [Latin rigidus, “stiff”]).

Longleaf (Pinus palustris, from Latin pīnus, “pine tree” and palūs, "bog, swamp" via palūstris, "boggy, marshy, swampy") and shortleaf (Pinus echinata, from Latin pīnus, “pine tree” and echināta, "prickly") pine trees adapt to the Southern States, from upper-coastal to lower-mountain biogeographies. Other Pinaceae family members, such as Table Mountain pine (Picea pungens, from Latin pīnus, "pine tree" and pungēns, “prickling”) trees, adjust to such altitudes as 2,500 to 4,600 feet (762 to 1,402.08 meters above sea level alone; Saturday, March 1, 2008, image of Pinus pungens trees in Rough Creek Valley, viewed approximately eight miles from Fighting Creek Nature Trail head, with snow-capped summit of Silers Bald Mountain (upper right) in Western Smoky Mountains of North Carolina and Tennessee in distant mountainscape: Brian Stansberry (BrineStans), CC BY 3.0 Unported, via Wikimedia Commons

Pitch and 2,500- to 4,600-foot (762- to 1,402.08-meter) elevation-proliferating Table Mountain (Pinus pungens [Latin pungēns, “prickling”]) pines respectively possess 3- and 2-needle fascicles around baseball-sized cones.

Eastern white pine (Pinus strobus, from Latin strobus, “odoriferous gum-yielding tree”) quarters straight trunks; smooth bark with horizontal lenticels; trunk-whorled branches yearly queuing a new layer. It realizes a resinous stickiness and a sloughable scaliness over all its parts, even its brown-gray, soft-scaled cones and its brown-gray bark rendered blocky with age. American sycamore; American and European hornbeam; black, river and yellow birch; black walnut and butternut hickory suggest similar upland/lowland, xeric/mesic, soil, natural-disturbance, land-use history, range-map studies.

Chris Graves, through Winter Tree ID 2 for Tennessee Urban Forestry Council, treated stream-channel, levee, first-bottomland, second-bottomland species and cover-, sassafras-, hybrid-, cherrybark oak-, native-species-related questions.

The University of Tennessee admits aged accolades as a higher-education institution in Knoxville, Tennessee, since its establishment 209 years ago, in 1794. Many trees always adorned, and still adorn, its eastern, oldest area, anointed The Hill, altered from the original the Barbara Hill, for Barbara Grainger Blount Gaines (Sep. 16, 1792-Nov. 30, 1836), daughter of Governor William Blount (March 29, 1749-March 21, 1800) and Mary Moseley Grainger (1761-Oct. 7, 1802) and second wife of General Edmund P. Gaines (March 20, 1777-June 6, 1849); crop of ca. 1877-1900 image of the University of Tennessee's oldest section, The Hill, with Science Hall on the southeastern slope and summit cluster of South College, West College, East College and distinctive cupola and belfry of Old College, oldest building (now demolished), built in 1828: Public Domain, via Wikimedia Commons
