Class 1: Introduction to Winter Plant Identification
Have you ever gazed at the frost covered branches of a tree in winter and wondered, "What kind of tree is that?" It can be tricky to identify trees without their familiar leaves, flowers, and fruits. Join us to learn how to identify dormant trees based on twigs and other clues. The course will cover 10 common landscape trees such as ash, maple, and pear at the family level. A classroom and field component are included. Please dress warmly. The beginning class serves as an appropriate introduction to the afternoon Intermediate Plant ID class.
Class 2: Intermediate Winter Plant Identification
If you know some basic botanical anatomy and have some familiarity with a few plant families, you are invited to take your plant ID skills to the next level with this intermediate plant ID class. We will focus on trees in the rose family, and how to tell one genus from another, including apple, pear, cherry and plum. The classroom session will be 40 minutes to emphasize field ID, so please dress warmly.
