There are many impacts involving invasive grasses in North America, which range from an ecosystem level to a community level to a genetic level. Such impacts influence habitat structure, disturbance regimes, and nutrient cycling. [2] A successful invasion of a grass may result in new hybrid species, which can have both good and bad results.
A foxtail is a spikelet or cluster of a grass, that serves to disperse its seeds as a unit. Thus, the foxtail is a type of diaspore or plant dispersal unit. Some grasses that produce a foxtail are themselves called "foxtail", also "spear grass". They can become a health hazard for dogs, cats, and other domestic animals, [1] and a nuisance for ...
Microstegium vimineum, commonly known as Japanese stiltgrass, packing grass, or Nepalese browntop, is an annual grass that is common in a wide variety of habitats and is well adapted to low light levels. It has become an invasive species throughout parts of the world, most notably North America.

Phalaris is a genus of flowering plants in the grass family. Species of Phalaris are distributed across all continents except Antarctica. They can be found in a broad range of habitats from below sea level to thousands of feet above sea level and from wet marshy areas to dry places. P. arundinacea and P. aquatica are sometimes invasive species ...

Pygmy hunter-gatherers in the Congo Basin in August 2014. A hunter-gatherer or forager is a human living in a community, or according to an ancestrally derived lifestyle, in which most or all food is obtained by foraging, [1] [2] that is, by gathering food from local naturally occurring sources, especially wild edible plants but also insects, fungi, honey, bird eggs, or anything safe to eat ...
One such episode in 1987 killed off a large proportion of the plants and the resulting increased sedimentation and greater growth of epiphytes on the remaining plants caused a secondary dieback event. The areas affected have since been reseeded and planted with rhizomes and have recovered. In general, the population of this grass is stable. [1]
