This tree is found in the montane rainforests of South America and is classified as a near threatened species by the IUCN. Trees can reach over 60 ft. high with linear-lanceolate shaped evergreen leaves arranged spirally around dark brown bark. Like all of its subgenus, the cone does not have bracts, and the seed has an apical ridge, as do its cousins in the other subgenus. The genus translates to “foot fruit” in greek. This is because at maturity, the scales are round and look like a fleshy berry which are eaten by birds to be dispersed in the forest. The species comes from one of the oldest genus of trees on Earth (along with Ginkgo), having been endemic to the continent of Gondwana.
Led by qualified instructors from the Mississippi State University Extension Service an the professional Arborist Association of Mississippi, this short course is designed to provide students with a basic knowledge of arboriculture. As a result of attending this course, students will be well-prepared to take the Certified Arborist Exam. The short course will employ a webinar format with class interaction occurring through email and chatroom. Many students will be professional tree workers; however, Master Gardeners, Master Urban Foresters, Master Naturalists, and anyone interested in trees are welcome to enroll.

Very common on red oaks. Caused by wasps or flies. Old galls look woody; new galls are lighter in color and spongy. This gall is common to red oak species. The tree makes the gall in reaction to insect larvae living in its tissue. While galls generally do not cause a terminal damage, a heavy infestation can damage young trees that are just trying to get established. Regardless of tree size, galls can decrease the vigor of the tree. Unfortunately, there’s not a whole lot that can be done. The best you can do is to keep the tree as healthy as possible with plenty of water and maybe a little slow release fertilizer at the right time of year and the correct quantity.

This native tree grows in coastal landscapes on the East Coast. It needs fire to regenerate, which is one reason why it’s historical range has shrunk significantly as a result of fire suppression. It is special for creating important habitat for threatened and endangered species like gopher tortoise and the red cockaded woodpecker. It’s known for its long needles (up to 18 inches) and large cones (up to 10 inches). It can live for well over 100 years.
In the third session of The Canopy webinar series, consulting arborist Guy Meilleur will discuss how to value and manage veteran trees.
Webinar attendees can earn 1 CEU credit (Certified Arborist CEUID: PA-15-645/CM for Urban Planners: #e.30471).
