"In New Zealand, good forestry establishment is sometimes impossible because of suppression of young trees by pampas grass (C. jubata and C. selloana) (Gadgil et al., 1984). The same authors estimated that releasing trees from pampas grass to allow them to barely survive cost about NZ$350 ha-1 in 1983, and that later tending operations like pruning and thinning have been estimated to increase total tending costs by 144%. Complete body cover is needed to protect operators from the sharp edges of the leaves." (CABI). (Horizon scanning draft for Gibraltar version 0.1 (Unknown).);
