Topographic Factors The elevation of Delta Natural Reserve is 5m and SWMA is 3m (Vancouver International Airport). The elevation of Watershed park on the other hand is 64m. As the elevation increases, there are fewer species and less dense coverage of the area because of the colder conditions, however, this is not a key factor in the difference in vegetation as the areas are within a 5 minutes drive from each other.

Delta Nature Reserve and SWMA were flatter in comparison to Watershed Park, as this park was located at a definite angle. Steeper slopes generally have thinner soils, less water content and are less acidic. The angle can affect the pH levels of the soil and the drainage levels and affect the types of vegetation growing.
