Now I'm going to mark on the toughness values for nylon fiber, bombyx or domesticated silkworm silk wool, Kevlar, and carbon fibers.

Ailanthus has been used to re vegetate areas where acid mine drainage has occurred and it has been shown to tolerate pH levels as low as 4.1 (approximately that of tomato juice).

On the other hand, a study in an old growth hemlock hardwood forest in New York found that Ailanthus was capable of competing successfully with native trees in canopy gaps where only 2 to 15 of full sun was available.

Ailanthus has also been introduced to Argentina, Australia (where it is a declared weed in New South Wales and Victoria), New Zealand (where it is listed under the National Pest Plant Accord and is classed an unwanted organism ), the Middle East and in some countries in South Asia such as Pakistan.
