Document Summary
The acidic environment increases the growth rate of the alnus incana, as well as precipitation through the air; this is because the well-drained soil allows the growth of small trees 2-4 m tall. These are the limiting factors that limit the distribution of plant alnus incana over the 5 locations. The overall result shown in the graph supports that station 4 and 5 are the best environment for the alnus incana. If there was partial water drainage at mer bleue, the most affected habitats would be the marsh and bog areas. Whereas the ecoton, forest and field areas, where the alnus incana thrives, would be least affected, since they are dry habitats that are exposed to a lot of sunlight, drying winds and acidic soil. Incana: w hat is your prediction regarding the consequence of the drainage on your plant regarding its abundance in its preferred habitat as well as its distribution in the mer.
