context_page_description: Rubus ellipticus, commonly known as aiselu, golden evergreen raspberry golden Himalayan raspberry or as yellow Himalayan raspberry, is an Asian species of thorny fruiting shrub in the rose family.
  It is native to China, Nepal, the Indian Subcontinent, Indochina, and the Philippines.
context_section_description: Rubus ellipticus is listed in the IUCN Invasive Species Specialist Group database as an Invasive species, one of the World's 100 worst invasive species.  It was first introduced in 1961 in Hawaii as an edible fruit and as an ornamental plant.
  The yellow Himalayan raspberry poses a threat to native communities because it forms thick, impenetrable thickets, and competes with the native Hawaiian raspberry. Abandoned farms and lands disturbed by feral pig populations are also susceptible to invasion.  Its ability to grow tall due to its stout stems is also a threat because of its ability to establish itself within the tree canopy.  The yellow Himalayan raspberry is also a threat to native flora because it can outcompete other plants.  More specifically, it has higher photosynthetic rates, has higher Nitrogen Fixation rates, and therefore a higher photosynthetic nitrogen use efficiency (or PNUE).
  The yellow Himalayan raspberry is currently only invasive on Hawaii. It is considered a noxious weed by the National Park Service and the Hawaiian Department of Agriculture.
