Ontario Forest Biomonitoring Network

The Ontario Forest Biomonitoring Network (OFBN) monitors the health of mixed hardwood forests across southern and central Ontario. The data set includes: * Individual Tree Data: Decline Index and other measurements of visual stress symptoms of each tree within 111 plots * Decline Index: The Decline Index is a weighted average of tree stress symptoms (percent dead branches, percent slight or strong chlorosis (pale green-yellow leaves) and percent undersized leaves). Averaged for hardwood trees found within each of the 111 plots in each year. * Invasive Plant Species Presence Data * Salamander Data: numbers of individuals of salamander and other animal species in 14 plots * Tree Regeneration Data: monitors numbers of tree seedlings/saplings in 102 plots * Woody Debris Data: amount of woody debris on ground in 102 plots
