It highlights the history of land use, from early settlers and overgrazing to the federal government’s intervention through the Bureau of Land Management (BLM). Various case studies across states like New Mexico, Nevada, Utah, and Oregon demonstrate how mismanagement led to erosion, invasive shrubs, and habitat loss. However, the film also shows successful restoration efforts through improved grazing systems, such as rest-rotation, reseeding, and structural erosion control. These strategies not only helped restore native vegetation and wildlife habitats but also supported sustainable livestock production. With proper management and cooperation, desertification can be reversed, offering valuable lessons for similar environments worldwide. 0:00 – Deserts are harsh, growing environments. Grasslands on their margins are vulnerable to becoming desert if mismanaged. 1:12 – Hugh O'Brien explains the film's purpose: to show how poor grazing practices destroy grasslands and how management can restore them. 2:00 – Early civilizations thrived on desert margins. In the US, grasslands supported settlers and livestock in the 1800s. 2:59 – Water rights conflicts in the West led to violence. In 1934, the federal government began regulating grazing on public lands. 4:34 – The Bureau of Land Management (BLM) began developing grazing systems based on the needs of plants and livestock. 5:12 – The US has 133 million acres of public arid and semi-arid land. Climate defines different types of deserts and margins. 6:47 – Overgrazing in New Mexico caused grasslands to deteriorate. Unpalatable shrubs like mesquite took over, creating desert-like conditions. 8:35 – BLM reduced livestock and sprayed mesquite. Combined with rotational grazing, this allowed grasses to recover. 10:12 – Poor follow-through led to repeated degradation. Effective grazing systems must be maintained consistently. 11:05 – San Simon Valley, once fertile, became a disaster zone due to overgrazing and river mismanagement. 12:15 – Settlers altered rivers, causing erosion known as head cutting, which destroyed topsoil and deepened stream beds. 13:56 – Restoration began with contour terraces and later more advanced structures like rock dams and spillways. 16:35 – Restoration brought back vegetation and wildlife. Careful livestock management prevents further damage. 18:00 – In Nevada's cold deserts, early overgrazing ruined native shrubs and grasses. Burros are now the main grazers. 20:33 – At Grey Hills, a rest-rotation system restored vegetation without chemicals, allowing pastures to recover seasonally. 21:53 – In Oregon, poor management led to overgrazing. The Vale Project used seeding and modern grazing to restore range. 23:58 – Rangeland drills were used to reseed crested wheatgrass. Seasonal grazing aligns with the growth cycle of new vegetation. 25:34 – Restoration supports both livestock and wildlife. Protecting desert margins preserves habitats. 26:41 – In Utah, early settlers used mesa tops for grazing. Overgrazing led to the spread of juniper and pinion trees. 28:07 – BLM used chaining (dragging heavy chains between tractors) to uproot trees and allow grasses to return. 30:00 – Restoring pastures helped sustain ranching and wildlife. Cooperation and management made this possible. 30:33 – The Watts Ranch in New Mexico used pasture rotation and water distribution to increase grazing capacity and restore streams. 33:00 – Across multiple states, proper grazing management stopped desert expansion. Lessons from the US may help other regions facing similar challenges. Motion picture films don't last forever; many have already been lost or destroyed. For almost two decades, we've worked to collect, scan and preserve the world as it was captured on 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
