The present day range of "Ascinara" is much less than what it used to be, as a result of both climatic changes and increased competition. In New Zealand in particular, the range of "A. lucida" has decreased. This is not a result of a pollen limitation, as "Ascarina" produces enough pollen to spread far beyond its habitable range, and even cross water to islands near New Zealand, but rather its vulnerability to both drought and frost. "A. lucida" grew reliably in regions of approximately 1500mm rainfall, and abundantly in areas of approximately 2500mm rainfall. In addition, a light frost would cause severe damage to leaves and flower buds. This vulnerability to climate change limits the range in which "Ascarina" can grow.
