Buckthorn may seem like an ordinary green plant, but it poses a significant threat to the natural landscapes of Minnesota and many areas across the country. With its dark green leaves and small, black berries, buckthorn can easily be mistaken for a harmless shrub. Unfortunately, this invasive species is taking over woodland areas, disrupting local ecosystems, and outcompeting native plants.
At Nic's Works Tree Service, LLC, we believe in the importance of preserving our local flora and promoting healthy ecosystems. Here’s what homeowners need to know about buckthorn, why it's a problem, and how to effectively remove it.
Buckthorn (Rhamnus cathartica and Rhamnus frangula) typically grows as a shrub or small tree, reaching heights of 3 to 25 feet. It features:
• Leaves: Glossy, dark green leaves that are oval-shaped and serrated at the edges. In the summer, these leaves are dense and can establish a thick canopy.
• Berries: The plant produces small berries (typically black or dark purple) that ripen in late summer and fall, making them appealing to birds.
• Bark: The bark is grayish-brown and can develop a distinctive pattern as it matures.
Part of what makes buckthorn so problematic is its rapid growth and ability to thrive in a wide range of soil conditions, allowing it to spread quickly and aggressively.
Buckthorn is classified as an invasive species because it outcompetes native plants for water, light, and nutrients. This overgrowth leads to a decline in biodiversity, affecting local wildlife that rely on native plants for food and habitat. It also alters soil chemistry and can diminish the quality of the ecosystem. Specifically, buckthorn has a few key impacts:
• Displacement of Native Species: Native plants and trees often struggle to compete with buckthorn, resulting in a decline in biodiversity.
• Wildlife Disruption: Many native bird species and other wildlife depend on native plants for food; as buckthorn takes over, these animals may struggle to find sustenance.
• Environmental Alteration: Buckthorn changes the natural structure of forests and prairies, impacting water retention and soil health.
Removing buckthorn can be a significant undertaking, but it’s crucial for restoring local ecosystems. Here are the steps Nic’s Works Tree Service can take to manage and remove buckthorn from your properties:
1. Identify and Assess: Before removal, we identify buckthorn on your land, compare it with images of native plants to ascertain what needs to be removed, and assess the size of the infestation to develop a removal plan.
2. Manual Removal: For small infestations, buckthorn can often be removed by hand. We simply pull the plants out, making sure to get the entire root system to prevent regrowth.
3. Chemical Treatment: For larger infestations, cutting down the plants may be necessary. This should be followed by applying a proper herbicide to the freshly cut stumps within a few hours to prevent new growth. We know how to do this and minimize environmental impact.
4. Monitoring and Maintenance: After removal, monitor the area for new buckthorn seedlings and call us if they are detected. Regular maintenance and seasonal checks can help ensure that buckthorn doesn’t reclaim the space.
5. Replanting Native Species: After removing buckthorn, we recommend replanting native species in the disturbed area. Native plants are adapted to local conditions, support wildlife, and help restore the natural balance of the ecosystem.
Summertime is the perfect time to address buckthorn and its various threats. By understanding what buckthorn looks like and employing effective removal strategies, Nic’s Works contributes to the preservation of Minnesota’s natural beauty and biodiversity.
