The situation

What’s happening to San Gabriel Mountains

The backyard wilderness for 18 million people. The San Gabriels provide drinking water, clean air, and the only accessible wildlands for some of the most underserved communities in Los Angeles County. Reducing this monument would be an environmental justice catastrophe for communities that have nowhere else to go.

Sources and methodThe situation, timeline, and threats: the MTJP threatened-lands record for San Gabriel Mountains, 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 listed for this place: a group is listed only under a sourced fact, and each chip opens its source. Local means headquartered in the state (the group’s own site, else the legal domicile on its 990) or the place named in its mission on its latest 990. In the fight means a case over the place naming it (the court docket), its own comment on a decision about the place (regulations.gov), an editors’ link with its source or its own page approved by a person here, or events on its own calendar held at the place. No fact, no listing. Org-reported figures are always labeled. Data verified as of 2026-11-01. No group pays to be listed on this page or for where it sits.
