snig

To snig is to haul a felled log across forest floor toward a landing or mill using ground-based dragging rather than overhead cable or truck transport. A chain, cable, or rope is anchored to the log at one end and pulled by a winch, tractor, or animal, typically moving the load in a straight line through brush, stumps, and uneven terrain. The log body itself slides or tumbles over obstacles rather than being lifted clear, which means the operator trades speed and equipment cost against ground damage and log scarring.

The practice is oldest in regions where timber fell near watercourses or established skid roads. A skidder, the modern forestry tractor with integral winch and drum, can snig logs across slopes and through dense growth where wheeled trucks cannot follow. On steeper ground or wet forest, snigging may be the only feasible extraction method short of helicopter or skyline. Cable length and winch power determine the reach; typical snigger radii run from 40 to 150 metres depending on terrain and machine class.

Damage accumulates through snigging. The log's leading end digs and barks as it is pulled; the trailing end can catch stumps and swing unpredictably. Soil is displaced, compacted, and often scoured away, exposing root systems and accelerating erosion on slopes. Smaller trees and saplings in the snig track are crushed. These externalities have made snigging controversial in conservation-focused forestry, pushing operators toward cable systems or shorter-radius mechanical skidding.

The term itself, origin unclear but recorded in English forestry vocabulary by the mid-20th century, appears Scottish or Northern English in origin. Snig may relate to snag or derive from Scandinavian languages common in timber trade jargon. Related terms include skid (a cleared drag route), snigger (a person or machine that snigs), and winch (the pulling mechanism).

Modern industrial forestry uses snigging mainly as a secondary or salvage operation. Primary extraction favors feller-bunchers and forwarders that load logs onto carriers, or cable systems that suspend loads. Snigging persists in small-hold forestry, steep terrain operations, and salvage of blow-down, where capital cost and access constraints make it the practical choice despite environmental impact.
