Traditional methods of reseeding degraded arid and semi-arid rangeland are expensive and frequently unsuccessful due to high rates of seed predation and seedling mortality. A runoff-based method is described that protects seeds from predation and degradation until soil moisture is available, then deposits them in favorable microsites for germination and establishment. Seeds are placed in three, 2 cm-diameter × 8 cm PVC tubes. The small tubes are capped with crepe paper and glued inside of a 7.5 cm-diameter × 15 cm-long tube which is capped with hardware cloth. The tubes are placed in small rills, gullies, arroyos or riparian areas and the seeds are released sequentially from the 3 tubes as flow depth increases. Seeds are deposited beneath piles of litter where soil moisture and temperature are more favorable for seedling establishment.
