Abstract
A population of dogtooth violets began to emerge in a small woodlot on Tokai University Sapporo Campus in 2001.The emergence was observed a few years after the grass mowing was partially terminated and/or delayed for several weeks to protect spring ephemeral plants and breeding birds.This study is probably one of the few cases in which the precise timing of the initiation of a dogtooth violet population was identified and that suggested grass mowing practices to be responsible for hindering their growth.The oldest plants were believed to be more over years old.The first flowering dates had a significant positive correlation with April temperatures.Future conservation concerns are discussed.
