vacciniifolia is likely to have been wildfire, and the survival of seedlings germinating after wildfires probably was limited only by browsing of young plants by native herbivores (Cameron 2006), and intra- and interspecies competition. Land clearing poses a major threat to remaining populations.
Although studies about the biomass quantification and the fine root length in the soil have already been carried out or, are presently under development (HAUSER, 1993; TORQUEBIAU & KWESIGA, 1996), little is known about their soil occupation profile (DHYANI & TRIPATHI, 2000) and, the possibility of interspecies competition (SCHMID, 2002) between species in mixed planting.
The complexity of the system may be increased by adding other species and implementing interspecies competition as well.
Interspecies competition for growth resources, such as water and light, can result in suppression of growth and biomass accumulation in the less competitive species.
Regarding to results which are obtained, there was no interspecies competition between intercropped sorghum and pear millet during growth stage.
These authors hypothesize that fish communities in reef environments are structured by several interacting processes, physical disturbances, recruitment limitations, resource availability of space, shelter and food, interspecies competition, and predation.

A drawback, however, is that our definition of interspecies competition requires that a competitive interaction be observed until the extinction of one species occurs.
