What happens to vegetation establishment on south and southwest facing slopes?

Establishment of vegetation on south and southwest facing slopes generally becomes more difficult due to several environmental factors. These slopes tend to receive more direct sunlight compared to other orientations, leading to higher soil temperatures and a drier microclimate. This increased exposure can exacerbate the evaporation of moisture from the soil, creating conditions that are less favorable for seed germination and plant establishment.

Additionally, the intense sunlight can stress young plants, making it harder for them to take root and grow vigorously. With the combination of increased dryness and heat, the range of plant species that can successfully establish themselves is reduced, often leading to slower or poorer vegetative cover compared to more sheltered slopes. Thus, recognizing the challenges posed by these conditions is vital for successful erosion and sediment control practices in these areas.
