“…Condensed tannin decreased, while N increased. Improved nutritional quality of coppice sprouts has been demonstrated in a number of Mediterranean shrub species, and both temperate and subtropical tree species (Stein et al 1992;Carlson et al 1993). These observations of reduced defences in rapidly growing shoots support resource-driven hypotheses of plant defence (e.g., Herms and Mattson 1992), but not herbivore-driven hypotheses (e.g., Rhoades 1979).…”

Research was conducted to investigate responses of Acacia karroo to severe defoliation, with or without debarking, in a semi-arid, subtropical savanna. A herd of 250 goats reduced available foliage by 87% in a 10.5-ha area of Acacia woodland over 3 weeks during the early dormant season (May). The goats debarked 37% of the trees. On average, bark was stripped less than halfway round a stem and 11% of the bark area was affected. Trees 1.6-2.5 m tall and 11-30 cm in basal circumference were most susceptible to debarking. A year later, there were no detectable effects of defoliation on the number of browseable shoots, internode length, shoot length, spine length, number of seed pods, neutral detergent fibre (NDF) or nitrogen (N). Defoliation tended to increase condensed tannin concentration (CT), but the effect was not significant (p > 0.05). The absence of goats during the growth season following defoliation allowed the trees to recover. Debarking had greater impacts on the trees than defoliation had. Debarking reduced the number of browseable shoots, while ringing at the base reduced CT and increased N. Debarking tended to reduce shoot and spine length, and halve the number of pods, but the effects were not significant (p > 0.05). Responses of basally ringed trees indicated rapid vertical growth when the trees were highly vulnerable to browsers and fires, suggesting strong selection for herbivore/fire tolerance. Among all treatments, excluding basal ringing, there were significant variations in NDF and CT between years. There was a positive relationship between N and NDF, and a negative relationship between N and CT, in 1 year, but not in the other. Among basally ringed trees, CT was negatively related to N, but NDF was not. The strong trade-off between N and CT in basally ringed trees probably indicates that large changes in root:shoot ratio are required to effect definite changes in defence.

“…Uresk et al, 1980;Stein et al, 1992;Carlson et al, 1993) and use by ungulates (Kruse, 1972;Peek, 1974;Pearson et al, 1995) have often been observed to increase. However, the burnt area in Rudy Raciborskie rapidly became dominated by wood smallreed (Calamagrostis epigeios), a species rarely eaten by deer unless it is young (Dzięciołowski, 1969).…”

“…Burning of habitats alters the abundance and quality of forage plants for deer (Carlson et al 1993;Hobbs and Spowart 1984;Thill et al 1987;Zimmerman 2004). Total cover of forbs and grasses in lightly to severely burned habitat in the southern Black Hills of South Dakota increased 59.1% 6 21.6% and 79.7% 6 27.7% (SE), respectively, from 2002 to 2003 (Zimmerman 2004).…”
