  1. Sow tree seeds after wildfire

    A controlled study in 1994-1996 in temperate coniferous forest in Washington State, USA (Schoennagel & Waller 1999) found that spreading seeds in burnt forest areas decreased the number and cover of native species. The number of native plants species (unseeded: 17; seeded: 15/m2) and their cover (unseeded: 41%; seeded: 21%) were lower in seeded plots. Total plant cover was similar between treatments (unseeded: 41%; seeded: 48%). Thirty-two plots (15 × 15 m) were established in each control (unseeded) and seeded area (seeded in September 1994 with seed mix containing 80% annual grass, 15%, short-lived perennial species and 5%  nitrogen-fixing legumes). Both areas (7 ha) burned in July 1994. Data were collected two years after seeding in eight quadrats (1 m2) in each plot.
