Land management for the lesser prairie-chicken should target restoration of specific grasses and forbs favored by the species and maintenance of sufficient shrub-cover to allow the species to avoid predators and thermoregulate.
Information regarding chemical composition of forb and shrub species and the dynamics of these nutrients throughout the year is limited or remains unknown in many plant communities (Huston et al.
Fecal analysis showed moose rely more heavily on grasses, sedges, and forbs (50.
Five species of forbs and four species of grasses were chosen according to site compatibility, prevalence in Tennessee or southeastern United States, price, and minimum time required for germination (Table 1).
Fall data from 1999 indicated that the 20 most abundant forb species varied between prairies, as did the average number of forbs and shrubs per plot (Table 5).
The effects of management on birds often are evaluated by relating measures of bird abundance and reproductive success to features of the vegetation, such as vegetation height, vegetation density, litter depth, and percentage cover of shrubs, forbs, and bare ground.
Individual planted prairie grass and forb species showed varying establishment successes (Table 2).
Univariate comparisons among regions showed that percent forb cover and woody vegetation height had the greatest amount of variation (Fig.
We explored relationships between cover by forbs and structure of vegetation using Pearson correlations and stepwise multiple regression (Zar, 1996).
2%) compares favorably with the grazed sites in this investigation but forb percentage (4.
In June 1993, shortly after the prairie was seeded with grass-rich mix (<10% forb content), flooding occurred on the southeast portion of the field.
