The cover by different plant life forms (forbs
, shrubs, or graminoids) was determined by summing covers of plant species belonging to each category within the quadrats and then calculating the mean value for each habitat type.
Further, dense patches of nettles are associated with reduced abundance of summer-reproducing forbs
and graminoids in Minnesota forests, along with increases in sugar maple (Biederman 2000).
The Conference Declaration commits participants to defending and promoting FoRB
as a universal, inalienable and non-derogable human right for all persons, as individuals and in community with others, through their work and respective institutions, by sharing information and mobilizing effective responses.
Fire season and prairie forb
richness in a 21year experiment.
There was also less perennial grass and forb
cover in the Northwest area.
Western ragweed was the dominant forb
in most quadrats (eight quadrats).
Cattle diets in tall forb
communities on mountain rangelands.
Aquatic species accounted for 1.9%, forbs
1.1%, and grasses at 0.9%.
Look for them before the grass and the forbs
get too tall.
