Sources and methodThe situation, timeline, and threats: the MTJP threatened-lands record for Browns Canyon, with per-item sources. Group crews and program ratios: IRS Form 990 via ProPublica Nonprofit Explorer, latest filed year, EINs on each group’s profile. Which groups are on the record for this place: MTJP editors tie a group to a fight only with a source link they have read, one link at a time. A group without one is shown as likely to care, a guess from the federal court record and the group’s own mission and footprint. Org-reported figures are always labeled.
