Sow seeds and plant individual plants Shrubland and Heathland Conservation

A replicated, randomized, controlled study in a degraded sagebrush scrubland habitat in California, USA (1) found that planting California sagebrush Artemisia californica plants followed by sowing of seeds did not increase cover of native plant species compared to only sowing of seeds, or only planting. Native plant species cover in areas where California sagebrush was planted and seeds were sown (7–14%) was not higher than areas where either seeds were sown (2–9%) or California sagebrush plants were planted (2%). California sagebrush plants were planted in six randomly located 1 m2 plots which were then sown with seeds, while six plots were only sown with seeds of shrubland plants, and another six plots were only planted with California sagebrush plants. Plant cover was recorded 1 m2 plots, every year between May and July. Year of the study is not provided.

Plant individual plants Shrubland and Heathland Conservation

A replicated, randomized, controlled study in a degraded sagebrush scrubland habitat in California, USA (DeSimone 2011) found that planting California sagebrush Artemisia californica plants did not increase cover of native plant species compared to sowing of seeds, or a combination of planting and sowing seeds. Native plant species cover in areas where California sagebrush was planted (2%) was not higher than in areas where seeds were sown (2–9%) or areas where plants were planted and seeds sown (7–14%). California sagebrush plants were planted in six randomly located 1 m2 plots, while six plots were sown with seeds of shrubland plants, and another six plots were planted with plants and sown with seeds. Plant cover was recorded every year in May-July in the 1 m2 plots. Year of the study is not provided.
