  • One replicated, randomized, controlled study in the USA found that covering the ground with mulch after planting increased total plant cover.

 

About key messages

Key messages provide a descriptive index to studies we have found that test this intervention.

Studies are not directly comparable or of equal value. When making decisions based on this evidence, you should consider factors such as study size, study design, reported metrics and relevance of the study to your situation, rather than simply counting the number of studies that support a particular interpretation.

Supporting evidence from individual studies

  1. A replicated, randomized, controlled study in 1991-1995 in a degraded temperate coniferous forest in Idaho, USA (Walsh & Redente 2011) found that covering the ground after restoration planting had mixed effects or no effect on vegetation cover depending on material used. Total plant cover was higher in plots covered with local redtop hay (46-49%) and erosion control blanket (50-54%) than plots covered with wood-fiber hydro mulch (33-35%) or uncovered (32-35%). Each of four covering treatments: local redtop hay (at 4.5  x 103 kg/ha), erosion control blanket (consisting of wood shavings of aspen and alder placed between two plastic nets), wood-fiber hydro mulch (applied at a rate of 1,682 kg/ha) and uncovered was applied in 1991 to four plots (3 × 10 m) at each of two hilltop sites. All plots were planted with western white pine Pinus monticola trees, shrubs and grasses before treatments in 1991. Vegetation cover was measured in 1995.
