Soil depth vegetation relationships on Niobrara shale in Colorado foothills
Sultan Maqsood Khan
ABSTRACT
The study was conducted on the Niobrara Shale hog-back in the Colorado Foothills near Fort Collins, to determine the effect of soil depth on composition, total cover, shrub cover and herbaceous cover of the vegetation. The analysis of variance snowed significant difference between the stands and t test gave significant difference between the shrubby and non shrubby stands. The herbaceous cover and total
vegetation cover were found positively correlated and shrub cover negatively correlated with the soil depth. The shrubs and herbaceous vegetation occupied thin and deep soils respectively.
