The third day differed a lot with the previous adventures. We started the day along the coast while performing a field study. Together we discovered the many invasive alien species that Portugal has to offer, amongst them we mainly focused on the Eucalyptus trees, pampas grass, ice plants, giant reed and the Sydney golden wattles. The guide that followed us on the walk told us more about these species. According to them, almost all of these IAS (invasive alien species) not only reproduce fast without natural threats but also easily lights on fire. The guides told us that Portugal has a big problem with fires in the forrest mainly because of the IAS’s wide spread. While walking we quickly noticed that big areas had been covered with a certain IAS’s without anything else growing there. For example, the Eucalyptus peels its bark by itself depending on the temperature. For the tree, peeling is only a way to adjust to the surrounding, but to the rest of the ecosystem this bark that falls to the ground prevents anything from growing because of its thickness. Later on during the day we continued our trip with a visit on a big marine center where we got a guiding and two different lectures about IAS’s and how they function in different habitats. However these lectures were meant for students with much higher pre-education than us. Because of this, the fact that the PowerPoint wasn’t readable and because of the horrible acoustic it was hard to understand anything at all. The consequence was a lot of sleeping students, now if we were one of the sleeping beauties is for us to know and for you to never find out.
When the day was over for everyone it continued for us Swedes. We went out to dinner with the whole gang including our dear teachers. After walking a bit we found a nice restaurant and spent the evening there. Anna and Johanna had the time of their lives, it is amazing what youth can do.
It’s scary to know how fast and dangerous these species are for the natural environment. Many of the plants that we saw today were really beautiful until you found out what horrible effects it has had on the surroundings. Maybe looks aren’t always worth it.
