Abstract: ABSTRACT. Nearly all remnants of temperate grasslands in southeastern South America are used for livestock ranching and are subject to habitat degradation resulting from this activity. Exploring how habitat features affect the composition of grassland avifaunal communities is a first step to understand how current cattle-ranching management practices impact avian diversity. We used canonical ordination to test for relationships between five habitat variables and the composition of the bird community in coastal… Show more

“…The greater height in AR resulted from the conspicuous presence of shrubs and Baccharis spp. ; this woody vegetation in grasslands provides resources for birds, increasing diversity (Dias et al ). Regarding the time of restoration, in the second year of active restoration the grassland bird species richness and composition resembled the reference area, whereas we had initially hypothesized that this would occur only in the third year.…”

“…Vegetation cover was classified in nine categories: short and tall grasses, herbs, shrubs, Eryngium spp., Baccharis spp., exposed soil, water, and cattle dung (Bencke & Dias 2010 unpublished data; Fuhlendorf et al ). Grass height strongly influences the presence of grassland birds (Azpiroz & Blake ) and woody vegetation (including Eryngium and Baccharis ) provides resources for them (Dias et al ). The five 1 × 1–m quadrats were arranged with one at the center of the point count and one in each cardinal direction (north, south, east, west), 50 m distant from the central point.…”

“…One factor likely contributing to this difference was the difference between the two grassland types in vegetation height, a variable that influenced the occurrence of three species. The results of some studies suggest that vegetation height is an important predictor of the occurrence of grassland birds, in addition to the amount of bare ground and litter depth (Fisher and Davis , Dias et al ). In our study, Blue‐black Grassquits and Chestnut Seedeaters were only observed in PR and Wedge‐tailed Grass‐Finches were more abundant in PR, the grassland type with taller vegetation and greater coverage of tall grass.…”

“…data). Eryngium and Baccharis are native plants, woody vegetation ( Baccharis) provides important resources for birds (Dias et al ), and some birds use Eryngium as a perch site (Dias et al ). To obtain a mean value for vegetation variables at the point‐count level, we calculated the mean for each of the five quadrats per point count.…”
