Comparative decay resistance of the heartwood of some common native species
For most outdoor projects, naturally rot-resistant wood is a good idea. Use this table to find the right decay-resistant species for your project.
|Resistant or very resistant||Moderately resistant||Slightly or nonresistant|
Baldcypress (old growth)1
Baldcypress (young growth)3
1 The southern and eastern pines and baldcypress are now largely second-growth, with a large proportion of sapwood. Consequently, it is no longer practicable to obtain substatial quantities of heartwood lumber in these species for general building purposes.
2 These species, or certain species within the groups sown, are indicated to have higher decay resistance than most of the other woods in their respective categories.
3 These woods have exceptionally high decay resistance.
