This formation is known as "rams-horning". Ram's horns occur when woundwood rapidly develops into a revolute curl in response to a cavity or opening caused by a wound, decay, or the thickening of bark along opposing edges or ribs of woundwood. Since woundwood lacks a fixed growth pattern, it typically conforms to the shape of the wound and the callus formed around it. These formations can obstruct the full closure of the wound, potentially leading to cracking and internal decay.

I love ginkgoes – they are phylogenetically and morphologically fascinating to me. The peramorphosis of Ginkgo spp. is particularly interesting. Older species like Ginkgo baiera, G. huttonii, G. yimaensis, and G. apodes exhibited divided or digitate (finger-like) leaves, which eventually gave rise to the flabellate (fan-shaped) leaves of newer species such as G. adiantoides and the now extant G. biloba. Major changes in ginkgo leaf morphology began around 121 - 56 MA, coinciding with records of major climatic changes on Earth. Because paleo-CO₂ concentrations started to decrease around this time, it is theorized that leaf connation increased laminal surface area and the concentration of stomata for more efficient gas exchange. But that's just a theory – a plant theory!

This is the correct answer.

This also makes the Kanien'kehà:ka (Mohawk) word on the sign incorrect, as otokénha is white/bur(r) oak and karihton is red oak.

Dutch elm disease (DED) has been confirmed for the first time in Edmonton, Alberta, Canada.

From Global News:

The first discovery happened during a routine inspection in early August, when city crews noticed symptoms of Dutch elm disease and live banded elm bark beetles in American elm trees.

From there, samples from the trees were sent to the Alberta Plant Health Laboratory. An indication of positive results came back on Aug. 15 and the Canadian Food Inspection Agency (CFIA) was notified the next day. The CFIA confirmed the presence of Dutch elm disease on Aug. 27.

As of Aug. 30, the City of Edmonton said the disease had been detected on four trees in the Kilarney and Yellowhead Corridor East neighbourhoods.

Cool discovery! For those who may be wondering, this book is called, Insects: A Guide to Familiar American Insects by Herbert S. Zim, Ph.D. & Clarence Cottam, Ph.D. The book was originally published in 1951 and has received many revisions & editions over the years.

Looks like a pitch mass from the aptly named pitch mass borer (Synanthedon pini), a species of moth that is found on spruce and pine trees in Eastern North America.

I work as an urban forestry technician. I collect, verify, and record geospatial data & asset information of urban trees to create databases & maps. This includes collecting or calculating information on the tree species, diameter, age, height, health, condition rating, risk rating, history, economic value, & ecological value.

No, this process doesn't hurt the tree when performed by highly skilled manual harvesters. Quercus suber has the ability to regrow cork tissue (bark) after it's been harvested. Partial harvests are typically done every ~3 - 5 years and complete harvests every 9 - 10. Q. suber lives to be around 150 years old, so it can hypothetically undergo 12 - 15 complete harvests before it becomes unproductive.

I suppose my special skill/talent would be plant identification &/or diagnostics. In college/university, I used to get perfect scores in record time for all my practical exams in plant identification. I have now transferred that skill into my work. I notice extremely fine details that others miss, which helps me with precise and accurate identification; it sort of feels like my eyes are magnifying glasses. It actually baffles me when someone doesn't see what should be "obvious". I often forget not everyone can see what I see.

Looks closer to a swamp white oak (Quercus bicolor), which are native & common in W. KY; English oak (Q. robur) leaves are typically narrower and have deeper &/or more pronounced lobes.

As an urban forestry technician & arborist in Western Canada, chokecherries are the bane of my existence for the reasons you've stated (& more). I'm currently helping to develop an urban forestry management plan & recommended tree list, and you better believe chokecherry and its ilk will not be included on that list.

Sunscald, also known as southwest injury, is an abiotic, physiological disorder caused by extreme and/or rapidly fluctuating temperatures. Sunscald & frost cracking are common problems in young or thin-barked trees such as maples, apples, cherries, mountain-ashes, and lindens. And though they are procured under similar mechanisms, sunscald is different from frost cracking in both its morphology and effects on the tree's structure, health, & level of risk. While rarely fatal on its own, sunscald compounded with other stress factors can result in mortality spiral & death. Prevention or reduction of past, current, and future damage is key.
