For hundreds of years, immigrants and natives to Oregon and the United States have brought in foreign plants that have both helped the economy and harmed the ecosystem. Many seeds brought into Oregon are helpful and grown successfully throughout the state, boosting the economy. Today though, in some counties they are taking distinct measures to eliminate many of the noxious weeds brought in through the years.
Whether brought over on purpose or accidently, invasive plants plague Oregon’s landscapes and fields. One plant that invades Oregon’s ecosystems is Cardous Pychocephalus which is also known as Italian Thistle. Italian Thistle is a plant native to Southern and Eastern Europe among other places. This plant grows densely and crowds out the wanted native foliage, the spindly stems and thorns prevent animals from grazing upon this plant. Acroptilon Repens, or Russian Knapweed, is another invasive plant that is scattered throughout Oregon. Russina Knapweed was brought over through contaminated Turkish alfalfa. This plant originated in Russia, Mongolia, Iran, among others. This plant is poisonous to horses if eaten in sufficient amounts. Something unique about this plant is that it has the potential to live longer than seventy five years. Bromus Tectorium, or cheat grass, which was originally from the Southwest Asia region and was introduced to the United States by contaminated grain. Cheat grass seed germinates during the winter months and begin to grow before the native plants do, thus taking nutrients and moisture away from native plants. Once they dry out, mid-June, they pose a fire hazard problems to the native plants. Tribulus Terrestis, or puncture vine, is a flowering plant whose seed has sharp spines tough enough to puncture bike tires and penetrate skin. Something that is surprising about Puncture vine is that it is used in medicines in Asia. Puncture vine when uninterrupted, grows invasively in turn taking land the native plants could have used. Cenium Maculatum, or poison hemlock, is a plant that is poisonous to people and animals alike. Poison Hemlock is native to West Asia, Europe, and North Africa but has since been introduced to many other countries. This plant tends to be most problematic in fields and meadows.
Not all plants brought into the United States have had negative outcomes, some plants brought over have had negative effects, many are helpful and boost the Oregon economy. Prunus Persica, or the peach tree, is a tree that originated in China. A peach tree produces two types of fruit, peaches and nectarines. Nectarines are produced when a peach tree carries a recessive gene that has it produce a fruit without fuzz and a colorful flesh. In Oregon the first peach trees were planted by peach pits in 1944 by Reverend Edw Evans Parrish. Since then Oregon has became the number eighteen peach producers in the United States with three and a half billion dollars in sales with only nine hundred sixety acres of land in production....
