Abstract

Paspalum conjugatum (buffalo grass).

Abstract

Paspalum conjugatum is a vigorous, creeping perennial grass with long stolons and dense culms that may grow up to 1 m tall. It has been extensively introduced as a forage and lawn grass and it can now be found naturalized across tropical and subtropical regions. P. conjugatum tolerates high levels of disturbance and pollution, grows vigorously under partial shade, spreads easily by seeds and stolons, and can withstand acidic and low-nutrient soils. Once established, this grass behaves as an aggressive weed in active pastures and agricultural lands, but also in disturbed and undisturbed natural forests and grasslands. It forms a dense ground cover that competes with and inhibits the establishment of other plant species, including other grasses and crops. In the Pacific region, it has been stated that some native forests have become extinct due to this grass pest.
