Species	Impacts can expected to have a deleterious affect on S. chinensis
Size	The area to be affected is small
Duration	The duration of impact will persist during construction and operation phases.
Reversibility	Habitat loss is irreversible
Magnitude	The scale of habitat loss is small in the context of the surrounding similar habitats.
Overall impact conclusion	Medium
