Sow tree seeds after wildfire
A replicated, randomized, controlled study in 2003-2005 in temperate coniferous forest in Washington State, USA (Dodson & Peterson 2009) found no effect of spreading seeds in burnt forest areas on total plant cover. Total plant cover was approximately 55% under both treatments. Seeded species cover was higher in seeded (8%) than in unseeded plots (1.5%). In 2002-2003, seeding (a mixture of perennial graminoids and forbs) and control treatments were randomly assigned to 8-16 plots (6×8 m) established at each of four sites in an area that was burnt by wildfire in summer 2002. Plant cover was measured in summer 2005.

Use fertilizer
A replicated, randomized, controlled study in 2003-2005 in temperate coniferous forest in Washington State USA (5) found that fertilization increased the cover of plant species that were seeded artificially but did not affect total plant cover. Seeded species cover was higher in fertilized (12%) than in unfertilized plots (8%). Total plant cover was approximately 55% under both treatments. In 2002-2003, fertilized (ammonium nitrate and ammonium sulphate) and unfertilized treatments were randomly assigned to 8-16 plots (6 × 8 m) established at each of four sites. Each site had first been covered with a mixture of perennial grass and herbaceous seeds. The area had been burnt by wildfire in summer 2002. Plants cover was measured in summer 2005.
