Plants That Cause Problems – “Invasive Species” DestinationOakland.com STOP! What is an Invasive Species? Imagine spring wildflowers covered with a mat of twisted green vines. This is a sign that Oakland County Offenders invasive plants have moved in and native species have moved out. Invasive plant species originate in other parts of the world and are introduced into to the United States through flower a variety of ways. Not all plants introduced from other countries become invasive. The term invasive species is reserved for plants that grow and reproduce rapidly, causing changes to the areas where they become established. Invasive species impact our health, our economy seed and the environment, and can cost the United States $120 billion annually! flower pod flower A Ticking Time Bomb Growing unnoticed at first, invasive species spread and cover the landscape. They change the seed pod fruit ecology, affecting wildlife communities and the soil. Over time, invasive plant species form a monoculture in which the only plant growing is the invasive plant. Plants with Super Powers Invasive species have super powers to alter the ecological balance of nature. They flourish seed because controls in their native lands do not exist here. The Nature Conservancy ranks invasive species as the second leading cause of species extinction worldwide. Negative Effects of Invasive Species • Changes in hydrology— seed dispersal wetlands dry out • Release of chemicals into the soil that inhibit Black Swallow-wort Cynanchum louiseae & the growth of other plants.

Glossy Buckthorn Frangula Alnus
Invasive Species—Best Control Practices Michigan Department of Natural Resources Michigan Natural Features Inventory 2/2012 Glossy buckthorn Frangula alnus Glossy buckthorn is native to Eurasia but has been com- monly planted in this country as a hedge and for wildlife food and cover. It was widely recommended for conserva- tion plantings in the Midwest until its invasive tendencies became apparent; it creates dense thickets and out-com- petes native vegetation. Its fruit is widely dispersed by birds and small mammals. Glossy buckthorn, like many invasive shrubs, leafs out early in the spring and retains its leaves late into fall, increasing its energy production and shading out native plants. It is a particular pest on wet sites and poses a significant threat to Michigan’s rich prairie fens, as well as other wetland com- munities. It is also successful on many upland sites including old fields, roadsides and open woods. Glossy buckthorn is an alternate host for alfalfa mosaic virus and crown fungus, which causes oat rust disease. It has also been implicated as a possible host for the soybean aphid. It is widely distributed in some parts of the state, but is just beginning to appear in others. If it is caught early in its initial invasion, it may be eradicated completely. Robert Vidéki, Doronicum Kft., Bugwood.org Identification Flowers: Habit: Glossy buckthorn flowers Glossy buckthorn is a small tree or shrub with a spreading are tiny with five greenish- crown growing up to 6 m (20 ft) tall. Typically, it has multiple white petals, arranged in stems when young, and develops into a tree with a trunk clusters at the bases of the that may reach 25 cm (10 in) in diameter at maturity. -

This is after splitting the genus into Rhamnus (buckthorns and redberries) and Frangula (coffeeberries) based on a combination of fruit, leaf venation, and flower traits (Johnston 1975, FNA). -
Fecundity Limits in Frangula Alnus (Rhamnaceae) Relict Populations at the Species’ Southern Range Margin

The Habitat Preference of the Invasive Common Buckthorn in West Holland Sub-Watershed, Ontario
The Habitat Preference of The Invasive Common Buckthorn in West Holland Sub-watershed, Ontario by Ying Hong A thesis submitted in conformity with the requirements for the degree of Master of Forest Conservation Faculty of Forestry University of Toronto © Copyright by Ying Hong 2018 The Habitat Preference of The Invasive Common Buckthorn in West Holland Sub-watershed, Ontario Ying Hong Master of Forest Conservation Faculty of Forestry University of Toronto 2018 Abstract The project objective is to examine the habitat preference of the invasive common buckthorn (Rhamnus cathartica) in West Holland Sub-watershed located in the Lake Simcoe Watershed in Ontario. Filed data from monitoring plots, dispersed throughout the West Holland, were collected as part of the natural cover monitoring in the watershed during the summer of 2017. In my capstone project, I will 1) examine the possible plot characteristics that are related to common buckthorn presence; 2) explore whether and how common buckthorn abundance is related to the plot characteristics and disturbance; 3) determine the relationship between common buckthorn and other plants in the plot; and 4) give recommendations regard to current common buckthorn issue. This research can improve the knowledge of the invasive common buckthorn in Lake Simcoe Watershed, which is crucial because the non-native common buckthorn is distributed extensively across southern Ontario. ii Acknowledgments I want to say thank you to everyone who gives me physical or/and mental support! Thanks to my supervisor Dr. Danijela Puric-Mladenovic offer me summer job and give me lots of help and advice on the capstone project, and my crew leader Kyle Vanin from whom I learn a lot in the field; thanks, Katherine Baird help me with GIS; thanks to other VSP crews for collecting data together; and thanks to OMNR, especially my external supervisor Melanie Shapiera and Alex Kissel; thanks, Steve Varga, Richard Dickinson, Dave Bradley, Wasyl Bakowsky, Bodhan Kowalyk.
