Sow grass seeds
A replicated, controlled study in 1973–1977 in a grassland where powerlines had been constructed in Arizona, USA (Hessing & Johnson 1982) found that sowing a mixture of native and non-native grass seeds did not alter vegetation cover in most cases. In two of three years, there was no significant difference in vegetation cover between seeded (8–10%) and unseeded areas (10–12%). In one year, seeded areas had significantly higher vegetation cover than unseeded areas in the spring (53% vs 34%) but not in the summer (18% vs 16%). After construction was completed in summer 1973, two areas were sown with a seed mixture of eight grass species at a rate of 15.3 kg/ha, while two areas were not sown with seeds. Vegetation cover was surveyed using eight 6.1-m long line transects in each area in summer 1975, spring and summer 1976, and spring 1977.
