We have several of these trees in the MHS Woods behind the Montgomery Humane Society. The tree is beautiful and has a sweet, lemony smell similar to Carolina Jasmine. Can anyone help me identify the tree?
I discovered this wonderfully smelling shrub called a Chinese Privet in our woods behind the Montgomery Humane Society and now the USDA says it’s an invasive species!

Discovering a Chinese Privet (Ligustrum sinense) can indeed be a mixed experience. On one hand, its fragrant flowers and robust growth can make it seem like a delightful addition to the landscape. However, as you’ve learned, it is classified as an invasive species by the USDA and various environmental agencies.
Chinese Privet was introduced to the United States in the early 1850s as an ornamental plant. Its characteristics, such as dense foliage and rapid growth, which made it popular for use in gardens and as a hedge, also contribute to its invasive nature in North American ecosystems.
Impact of Chinese Privet as an Invasive Species
Competition with Native Species: Chinese Privet can form dense thickets that outcompete native flora for light, space, and nutrients. This alteration of the habitat can lead to a decline in native plant species, which in turn affects the biodiversity of the area.
Effects on Wildlife: The alteration of native habitats can have cascading effects on local wildlife. While some bird species may use privet for shelter or consume its berries, the overall change in plant diversity can negatively affect native species that rely on indigenous plants for food and habitat.
Soil and Water Impact: The alteration of the landscape by invasive species like Chinese Privet can affect soil chemistry and hydrology. Dense thickets can lead to increased runoff and soil erosion, impacting water quality in nearby streams and rivers.
Management and Control
The management of Chinese Privet involves several strategies:
Mechanical Control: This includes methods like cutting, mowing, and hand-pulling of seedlings. Repeated actions are often necessary as privet can resprout from roots and stumps.
Chemical Control: Herbicides can be effective, especially when applied to freshly cut stumps. However, care must be taken to avoid impacting non-target species and to comply with environmental regulations.
Biological Control: Research into biological control agents is ongoing. Some potential agents include insects that specifically feed on Chinese Privet, though this method requires thorough study to avoid unintended ecological consequences.
Community Engagement: Raising awareness about the impact of invasive species and promoting the use of native plants in landscaping can also help manage the spread of species like Chinese Privet.
Given the location of your discovery near the Montgomery Humane Society and the potential for this shrub to affect local ecosystems negatively, it might be beneficial to consult with local environmental or agricultural extension services to determine the best course of action for managing or eradicating the shrub from your area. Engaging in removal efforts not only helps protect your local ecosystem but also serves as a community example of responsible environmental stewardship.
