Basic Tree Identification
Proper tree management starts with knowing the tree you’re managing. When trying to recommend an appropriate treatment, diagnosing an issue, or understanding how a tree will respond to a change in conditions, identifying the tree you’re dealing with is the first step.
This basic identification workshop serves as an introduction to common terms, concepts, and techniques in tree identification. The objective of the course is to get you familiar with how to identify a tree, covering leaves, fruit, bark, twigs, and form.
As there are well more species that can grow in our region than can be covered in a single basic workshop, focus will be on larger concepts that will lay the ground work for future identification. We will cover the use of dichotomous keys and get familiar with descriptive terminology to help narrow down unknown species.
The workshop will be inside for the first half and will go outside for the second half to get familiar with using the concepts and terminology in the real world. The workshop will be hands on, and questions and interaction is encouraged. Please bring proper attire for standing and taking notes in inclement weather.
