- Title
PRODUCTION AND NUTRIENT CONTENT OF TWO SHRUB SPECIES RELATED TO FIRE IN CENTRAL IDAHO.

- Abstract
Nutrient content and weight of current year's growth of Cercocarpus ledifolius Nuttall and Physocarpus malvaceus (Greene) Kuntze in central Idaho were obtained during early July in the years 1987-2007. The purpose of this work was to determine whether there was significant variation between years and whether mean monthly temperatures and total monthly precipitation could predict the variation. A wildfire in August 2000 caused P. malvaceus to vigorously resprout. Significant differences between years occurred for all nutrients for both species. October temperatures best predicted weight of current year's growth in C. ledifolius, whereas prediction equations for nutrients involved spring temperatures and precipitation, primarily for June. January mean temperature and December precipitation best predicted weight of current year's growth, and spring mean monthly temperatures best predicted nutrient levels in P. malvaceus. Future changes in production and nutrient content of these species that are not predicted may be related to climate change.
