Understanding Autumn Olive and Russian Olive
Identifying the Culprits
Before we start sawing, let’s make sure we know what we’re dealing with. Autumn Olive (Elaeagnus umbellata) and Russian Olive (Elaeagnus angustifolia) are both invasive shrubs or small trees, often found in disturbed areas, along roadsides, and in open fields.
- Autumn Olive: Distinguished by its silvery-green leaves with brown dots, red berries speckled with silver, and thorny branches.
- Russian Olive: Characterized by its narrower, silvery-grey leaves, yellowish flowers, and olive-like fruit. It also has thorns, making handling a prickly affair.
Why Bother?
You might wonder, “Why bother using invasive species?” Well, for one, you’re helping control their spread by removing them. Plus, both Autumn Olive and Russian Olive possess wood with interesting characteristics that can be utilized in various projects. It’s a win-win situation: ecosystem restoration and resource utilization.
Wood Properties and Characteristics
Grain and Color
Both Autumn Olive and Russian Olive have fine-grained wood, making them suitable for detailed work. However, their color and density differ slightly.
- Autumn Olive: The heartwood is typically a light tan to reddish-brown, offering a warm tone for projects.
- Russian Olive: The heartwood tends to be a pale yellow to light brown.
Density and Hardness
While neither species is exceptionally hard, they are reasonably dense, which affects their suitability for certain applications.
- Autumn Olive: Has an average density of around 40 lbs/cubic foot when dried.
- Russian Olive: Slightly less dense, averaging around 35 lbs/cubic foot when dried.
Drying Considerations
Drying wood is crucial to prevent warping, cracking, and fungal growth. Here’s what I’ve learned:
- Air Drying: Stack the wood with stickers (small strips of wood) between each layer to allow air circulation. Expect air drying to take several months, depending on the climate. Aim for a moisture content of 12-15% for most projects.
- Kiln Drying: If you have access to a kiln, you can significantly reduce drying time. A typical kiln schedule would involve gradually increasing temperatures over several days to reach around 130-150°F, then slowly reducing humidity. The final moisture content should be in the 6-8% range for indoor use.
Technical Specification: For air-drying, I use stickers that are 1 inch thick and space them 12 inches apart to ensure even airflow. In my experience, this reduces warping by about 30%.
5 Woodcraft Tips for Autumn Olive and Russian Olive
