Phenology and reproductive allocation in Andropogon scoparius
(Gramineae) populations in communities of different successional stages.
Little bluestem (Andropogon scoparius
) was by far the most common species on all three transects.

Although index of commonness values show Andropogon scoparius
to be the major species in all three transects before and after treatments, commonness results also show that the study area was undergoing natural succession with Helianthus tube rous and Solidago graminifolia increasing in all transects.
Vegetation at Konza was representative of unplowed native tallgrass prairie and was dominated by the [C.sub.4] grasses big bluestem (Andropogon gerardii), indian grass (Sorghastrum nutans), switch-grass (Panicum virgatum), and little bluestem (Andropogon scoparius
), but also included a diverse assemblage of other grass and non-grass plant species (Collins et al.
Type 1 is characterized by high frequency and cover of graminoids (especially Andropogon scoparius
) and forbs, including numerous weedy or early successional species.
Nine upland weedy species were found and of those nine, three occurred quite frequently: Eupatorium capillifolium in six bays, Cyperus globulosus in five bays and Andropogon scoparius
in four bays (Table 2).
Common species were broom sedge (Andropogon scoparius
), weeping lovegrass (Eragrostis curvula), Downy chess (Bromus tectorum), fescue species (Festuca spp.) and Japanese honeysuckle (Lonicera japonica).

Most of the dominant tallgrasses in the Great Plains are [C.sub.4] species: Andropogon gerardii, Andropogon scoparius
, Panicum virgatum, Sorghastrum nutans, and Spartina pectinata (Kucera 1991).
Collins and Quinn (1982) found reduced Andropogon scoparius
seedling growth when grown in pots with Myrica pensylvanica.
