Tejon Ranch (conservation easements)
108,992 acres (441 km²) across 10 separately recorded conservation easements (36 disjoint rings), drawn from USGS PAD-US — the federal Protected Areas Database, not OpenStreetMap, since no usable OSM boundary exists for this private ranch.
Area 108,992 ac PAD-US, 2026

Established 2008 Ranch-Wide Agreement
Elevation 115 – 2,336 m (DEM)
Largest contiguous private property in California — 270,000 acres owned by the publicly traded Tejon Ranch Company (NYSE: TRC)2008 Ranch-Wide Agreement placed 240,000 acres (90%) into permanent conservation, stewarded by the independent nonprofit Tejon Ranch ConservancyThe 108,992 acres mapped here are the conservation easements individually recorded in PAD-US under the Conservancy's name — a real, documented subset, not the Conservancy's full stated 240,000-acre managed area
The remaining ~10% of the ranch is designated for agriculture, grazing, oil, and planned development (Tejon Mountain Village, Centennial, the Tejon Ranch Commerce Center)
Acreage and history: Tejon Ranch Conservation and Land Use Agreement (2008, SEC Ex-10.28); Wikipedia "Tejon Ranch" citing Tejon Ranch Co. filings. Boundary drawn from USGS PAD-US, Manager Name feature service, EsmtHldr='Tejon Ranch Conservancy' (queried 2026-07-29). Note: PAD-US's own reported acreage sum (108,992 ac) and the shape drawn here (computed at ~441 km² / ~109,975 ac) agree to within 0.9%, a clean cross-check with no gross topology errors — but this is a documented subset of easements, not the Conservancy's full 240,000-acre managed area (see the in-app record). Perimeter and compactness are computed from the digitised rings and are therefore scale-dependent.
