Now lots of these old giants are being felled, some because they're dying of canker, but most because dairy farmers don't want them around their cows and heifers, as the green foliage induces miscarriage. So I get lots of macrocarpa shavings, bark, and offcuts, and it's one of the main components of the poultry bedding and mulch around the property. It decomposes in a similar manner to most other softwood, although not as fast as pine.
The thing about most cypresses is that the oils that make them resistant to rot and insects don't stand a chance against the fungi that enter from the soil. Macrocarpa is regarded as a durable timber here as long as it's not in contact with the ground.
