Abstract

When soil is moist and wind is at a gale force, the term used to describe blow down of old trees is windthrow. In contrast, toppling is a term used when planted pines lean more than 15° during the first decade after transplanting. Pines tend to topple more than other conifers and fast-growing species topple more than slow growing genotypes. Large areas of pine plantations have toppled before age 8 years. This paper describes some toppling events that have occurred in 18 countries and includes 16 questions about toppling.
