What happened
Thunder Valley Community Development Corporation describes itself as a holistic organization working for the liberation of the Lakota people. Its mailing address is Porcupine, South Dakota, on the Pine Ridge Reservation. Its vision, on its Mission page, is a liberated Lakota Nation through language, life ways and spirituality. Its team page lists Trenton Old Horse as Chief Executive Officer and Beau LeBeaux as Board President.
The organization has eight initiative areas. One, Lakota Land Systems (formerly the Food Sovereignty Initiative), runs small-scale no-till market gardening, a composting program, a geothermal greenhouse and a bison restoration project. The initiative page says the bison restoration is spread across 40,000 acres near Badlands National Park. The page does not say who holds title to that land. The land team includes Brandon Big Eagle as Lakota Land Systems Director and Justin Pourier as Bison Restoration Manager.
The other initiatives cover language and education, regenerative community development, youth leadership and a Lakota Advocacy Center that trains advocates and conducts climate research.
ProPublica Nonprofit Explorer lists Thunder Valley Community Development Corporation of Porcupine, South Dakota, as a 501(c)(3), exemption issued March 2007. The acreage and program descriptions are the organization's own statements.
Good to know. The pages do not say who owns the 40,000 acres used for bison restoration, so this is not a land return.

Research notes. Title or lease status of the 40,000 bison-project acres is not stated on the pages read, so this entry does not describe a land return. Lakota-led status is shown by named Lakota staff and the organization's own words; the board was not read individually. The EIN is not on the site; it was matched through ProPublica by name and town.
