213	Ice rise	A mass of ice resting on rock and surrounded either by an ice shelf, or partly by an ice shelf and partly by sea. No rock is exposed and there may be none above sea level. Ice rises often have a dome-shaped surface. The largest known is about 100 km across.
214	Ice rise boundary	The boundary of the ice rise.
282	Ice rumple	A locally grounded area of ice shelf which is overridden by an ice sheet. ice rumples are distinguished by crevassing together with a rise in the surface. The criterion for distinguishing between ice rumples and an ice rise is the direction of ice movement as shown by the crevasse pattern. ice may be deflected or even halted by ice rumples, but in an ice rise, movement is independent of that of the ice shelf and, being inthe main radial, will in places oppose it.

221	Introduction of plant species	Plants which have been translocated by human agency into lands or waters where they have not lived previously, at least during historic times.

They may become liable to rapid genetic changes in their new environment. Many harmful introductions have been made by persons unqualified to anticipate the often complex ecological interaction which may ensue. On the other hand many plants introduced into modified or degraded environments may be more useful than native species in controlling erosion or in performing other positive functions.
