The Giant huntsman spider is huge, but not deadly to humans. Biggest in the world, the Giant Huntsman Spider was just recently discovered in 2001 in a Cave in Laos.
Because of reduced competition from other trees, it tends to thrive in barren soil containing too much sand, gravel, or clay. Growth and development of young trees is rapid, and their longevity can extend to 50-100 years. Siberian Elm is resistant to Dutch Elm disease, which is often fatal to other elms. It is prone to storm damage from wind, snow, and ice (especially the latter), causing breakage of branches and twigs that can litter the ground underneath the tree.
Life Span. The Virginia Big Tree Program has compiled a list of common trees of the Americas and their life spans. The Balsam Poplar lives an average of 100 years and can live up to 150 years. The Yellow Poplar has a much longer life span at 250 years on average, and a maximum of 450 years. The Hybrid Poplar will only reach 30 to 50 years of age, a relatively short life span.
