Effects of Cattle Management on Oak Regeneration in Northern Californian Mediterranean Oak Woodlands

Figure 2

Density of different oak class sizes.

Predicted density of different class sizes found at our study depending on the presence or absence of cattle (N = 72 sampling plots). Error lines are 95% confidence intervals. Note that in the case of adult trees the confidence intervals for predicted values are not visible because of their small size. Young plants: seedlings (plants with basal diameter less than 1 cm) and saplings (plants with basal diameter>1 cm and height<130 cm); Adult trees: plants with basal diameter>7.5 and height>130 cm.
