Well technically, wood release is turning the user's chakra into the source of life for the plants to use as a medium for them to grow. That's why I personally think it's attributed to his whole Asura chakra/Yang/life force thing. Yeah but Yamato's wooden planks aren't living, so wood release can be used without yang but is weaker.
