Welcome to my page! I haven't posted on social media in a while due to my busy schedule, but I've decided to make a conscious effort to post more frequently. I've dedicated most of my life and studies to plants, trees, and the natural world. Moving forward, my goal is to share my work and passion for nature with you while providing the best up-to-date knowledge and information. Stay tuned for more updates and insights into the wonders of the natural world! I hope you will enjoy these posts as much as I will and that they provide you with interesting information you can use!
Fraxinus quadrangulata
I was out disc golfing at Steen Park in Aylmer, where I frequently go, when I discovered a rare Fraxinus quadrangulata, commonly known as blue ash. This blue ash is one of the six ash trees native to our region. What makes this find particularly interesting is that, in Ontario, we rarely see large ash trees in our natural Carolinian forests due to the devastating effects of the Emerald Ash Borer (EAB). This invasive beetle, native to East Asia, has no natural predators in North America, making it a significant problem and highlighting the need for human intervention to control its spread.
For quick identification, look for opposite bud arrangements and compound leaves with 5-7 leaflets per leaf. Blue ash is distinct among native ash trees due to its four-sided twigs, which is reflected in its scientific name quadrangulata (meaning "four-angled"). It prefers full sun and well-drained to medium wet soils and is particularly noted for its drought tolerance.
Interestingly, blue ash is considered the least susceptible to EAB compared to other native ash trees. The inner bark of the blue ash has a blue hue and was historically used as a dye by Native Americans, which is why it’s called blue ash. Like other ash trees, blue ash is wind-pollinated and does not rely on insects or animals for pollen transfer. It’s an important species to protect due to its adaptability to various soil conditions, drought resistance, and genetic diversity, making it a strong candidate for resilience against climate change.
