All these months we have described some of the flora and fauna of our Potrerillos. But every day we see espacies plant and animals that are not native but were introduced and reproduced so easily that are already part of the environment. They are known as exotic. Rosehip abounding in streets and streams, and is already climbing into the hills colonizing their streams, is a plant species in the early twentieth century was not known in the country. Early European immigrants brought the plants as part of their food culture back then. Its fruits were of great taste in frutívoras birds began to distribute their seed until the plant floors virtually colonized much of the country including our foothill environments. Here to stay forever. It is well known that with a delicious sweet fruit and is made at this time cosmetics and shampoo. Exactly the same story is repeated for other species but this animal case: trout. The difference is that the expansion was not natural but man that was in charge of promoting captive breeding and planting in rivers and streams. The consequence was that competed and displaced many native fish species that almost became extinct in the teeth of this voracious carnivore predator. A level of 99% of forest species we see are alien to Potrerillos, poplars, willows, sweetgum, birch, etc. they are not native. There is only one own forest plant species we know as chacay, and found along streams. It differs from other trees in having their leaves too small. Despite these native species not already part of our culture and as such enjoyed it. So I invite you to a good trout dish and dessert cake with sweet musk. Bon Appetite! Texts: Ranger Andy Elias
