Buckthorn By Katie Paulson and Sophia Kim Buckthorn Problems Buckthorn Solutions What is being done to control buckthorn? Getting Rid of Buckthorn Statistics Why should we care? How does it affect us? cont. Why is buckthorn a problem? Why should we care? How does it affect us? How and when was buckthorn introduced? What is buckthorn? Where is buckthorn from? The Background
Of
Buckthorn Buckthorn is a shrub or small tree of the genus Rhamnus, typically bearing thorns and can grow from 10-25 feet. Common buckthorn provides fruit for birds. Sea buckthorn can be used for a variety of things, such as medicine, makeup, foods, reducing cancer illness, and other things. Buckthorn is locally found in temperate and subtropical Northern Hemisphere climates, but was brought to the U.S. from Eurasia. Buckthorn was introduced in the 18th century, but started to become widespread across Northeastern America in the 19th century. It was brought from Eurasia as an ornamental plant, for fence rows, and wildlife habitat. -Buckthorn is really dense, so it shades out other native plants that grow on the forest floor. This contributes to erosion, which can damage the ecosystem, pollute our water, and contribute to less fertile soil for farmers
-Buckthorn, because of its fast growth rate, threatens and invades forests, wetlands, prairies, and other natural habitats. This degrades wildlife and their habitats, and affects us because tourism could decrease.
-Buckthorn also carries an oat rust that damages oat crops. Not much is being done currently to control the growth of buckthorn. It is not as invasive in Michigan.
Some small solutions so far are getting rid of buckthorn but burning it, cutting down larger buckthorn and applying herbicides to stop growth, replacing buckthorn with other noninvasive, native plants, and using sea buckthorn as oil. In one square foot of land, there's 15 buckthorn berry seeds. The population of buckthorn probably increases exponentially at a nonlinear rate because of how fast a rate buckthorn grows and spreads. We predict that the population of buckthorn will increase greatly if we do not do anything about eradicating it. Buckthorn has small green leaves and small berries that vary from green to blueish purple. Buckthorn is a big issue for many reasons:
-It changes the soil chemistry with chemicals, killing native plants and inhibiting growth of other species
-It spreads rapidly, replacing native species and lowering species diversity
-It serves as a host to other pests
-Forms an impenetrable layer of vegetarian -Eradicating buckthorn also costs a lot of money. This greatly concerns the economy because of how expensive and labor intensive getting rid of buckthorn is. +statistics For our way of spreading the word, we actually went out and cut down buckthorn plants in our own backyards. We cut them down and then made sure we properly removed the roots, applied herbicide, and got rid of it for good.
