Right, the Ownership Layers works with BLM data only -- before it contained USFS, NPS and other data. A new install of TF includes this BLM-only string for land ownership. It's just unfortunate that they removed a lot of the useful data from it.
For a while they kept a backup server with the old data, but that disappeared. I have tried to find another source, but have been unsuccessful so far.
Thanks for the post.
