SHORT COMMUNICATION MINERAL ELEMENT CONCENTRATIONS IN FOLIAGE AND BARK OF WOODY SPECIES ON AUCKLAND ISLAND
Summary: Mineral element concentrations are presented in leaf and bark material from six woody species growing at a single site on the subantarctic Auckland Islands. Foliar total mineral element concentrations range from 5.81 % (Olearia lyallii) to 2.71 % (Dracophyllum longifolium), the lowest conce...

Summary: | Summary: Mineral element concentrations are presented in leaf and bark material from six woody species growing at a single site on the subantarctic Auckland Islands. Foliar total mineral element concentrations range from 5.81 % (Olearia lyallii) to 2.71 % (Dracophyllum longifolium), the lowest concentrations occurring in slow growing species tolerant of nutrient-poor soils. The browse preference of introduced goats is correlated with high foliar potassium levels while species that are preferentially debarked (Pseudopanax simplex and Myrsine divaricata) have the highest bark calcium concentrations. |
