La Quebrada Report
By: Luciana Garcia
This few weeks we have been going up to study La Quebrada. We filled some tables about the trees, plants and animals. The tables contained information such as the height, common/scientific name, a drawing and other characteristics. We also made a quadrant were we counted all the plants of the same kind and we could get a picture about how many plants of that kind were in that area (estimated number).
Some of the plants we found in La Quebrada were typical colombian forest plants, such as Tuno Amarillo ( Miconia biappendiculata), Black Cherry (prunus seratina) and Acacia Morada (Acacia Baileyara). Many of the plants we saw were in the same quadrant, that ment they grew a lot in that area. For founding the scientific/common name of each plant we brought leafs of each of the plants and used a book for identifying them. Looking at many of the plants we found out that they had many characteristics that made them all similiar, many of them had similiar lines at the back like "veins", and other part had similiar colors and shapes.
In La Quebrada we found many kinds of trees wich we measured using special tools and we identified the ones we chose, we found cold climate trees like Amarraboyo (Meriania nobilis), Tibar Comun (Escallonia paniculata), Espandero (Myrsine coriacea) and many others. The trees in our quadrant and near that zone had many similaryties, many were had similiar heights, leafs/flowers, abundance and circumference.
For the last time in this experiment we went up to the creek to get the information about the animals living in this ecosystem, we found many animals about different backrounds; Rosey Reds (Pimephales Promelas), Common Black Bird (Turdus merula), Bee (Anthophila), etc. We found very similiar animals, mostly insects most of them are really dark colored insects, due to the cold climate I can assume that they need a certain temperature. The habit of each animal is different, The Rosey Reds since it lives on the creek it needs the fresh and clean water with a reasonable amount of food, it also needs a place to hide from birds and other animals. The Common Black Bird needs different things than the fish, or the bee, it needs shelter and food, fish, they can get fish from lakes, creeks and other water sources with life, they need to live near a water source to be able to have have food. The Bee needs to live in a place were they have flowers to be able to do they work and pollinate the flowers and to be able to eat. There around 20,000 different espicies of bees, only about 50 live in these types of climates.
In conclusion, this experiment taught me that the creek is really important to all the nature that lives on that area and that without it many especies wouldn't be able to live, I also noticed that every of the living organisms depends on another one to live and most of all the nature here needs the creek.
