In this course, participants will learn to identify woods by studying both macroscopic and microscopic anatomical features. This workshop is suitable for those with at least an entry-level familiarity with wood anatomy and species identification and will build on skills learned in Wood Identification: Level 1. Participants should already be familiar with the terms tracheid, parenchyma, vessel, fiber, and ray, and should be able to locate such features on samples of typical species like oak and pine; if not, attending the Level 1 workshop, or self-study prior to the Level 2 workshop, is strongly recommended.
Many hardwood species can be identified by observing the structure of the wood viewed on the end grain with a hand lens, but such identifications can be subjective and depend heavily on the personal experience of the identifier and their reference materials. More definitive wood identification depends on the observation of microscopic characteristics. Learning which microscopic features are diagnostic and how to find and identify them is necessary in order to have a complete toolkit for performing wood species identification.
Microscopic characters may seem complex at first, but they are in fact typically less subjective and also more plentiful, and so permit far greater identification confidence. To properly interpret the wood anatomical characters that enable identification of an unknown sample, participants will learn some basics of wood evolution and tree growth and function as living organisms. This gives a better understanding of what wood is, how it varies, and opens up a whole new way of seeing wood.
There will be a review of wood anatomy that includes practice examining samples of hardwoods and softwoods with a hand lens. This will be followed by a detailed look at microscopic features, what they are, and how to find them. All participants will have access to microscopes. There will be some prepared slides of thin sections ready for study, but the emphasis will be on participants making their own hand sections and viewing them under the microscope.
The workshop will focus on common hardwoods and softwoods of North America. Skills learned can be applied to the identification of non-native species as well.
Learning objectives for this workshop include:
By the end of the workshop, participants should be able to put the knowledge gained into immediate practice. Participants are requested to bring a utility knife, their own hand lens, a copy of Hoadley's Identifying Wood and other reference materials with which they are familiar, and a flash drive. Participants are also invited to bring small samples of unknown woods. Utility knives will be provided for those traveling by air.
Participants will receive electronic copies of presentations and some reference materials. A set of wood samples will be provided for students to use in preparing their own sections.
