I don't think anybody's intent is to chase down and admonish bowyers or even be critical of anyone in bowhunting using a wood product. An individual bowyer's wood use, or an individual archer's wood use, is a little drop in the bucket. The question has been posed in a positive manner to try and find any source of bows being created from wood positively identified as produced from sustainably managed forests.
The bucket gets filled somehow, drop by drop. The option of "certified" wood products allows market access to small landowners and to operations that manage in a positive manner, domestically and internationally. When people see me chasing down bowyers in order to give them extra money for such a bow, maybe a few more will offer that option. Drop by drop....
Domestic vs. international is not the deciding factor in this question either. There is a lot of mismanaged and un-managed forest in the U.S. And there are quite a number of wood dealers that offer cocobolo, ebony, zebrawood, purpleheart, goncola, etc... from well managed forests that provide for conservation and economic development.
