Plant/sow seeds of nurse plants alongside focal plants
A replicated, randomized, controlled study in 1993–1994 in former shrubland in California, USA (Marquez & Allen 1996) found that sowing California sagebrush Artemisia californica seeds with the seeds of nurse plants reduced its survival in four of seven comparisons and reduced its biomass in seven of seven comparisons. In four of seven comparisons, California sagebrush seedlings showed lower survival where they were sown with seeds of nurse plants (5–75% survival) than when they were sown without seeds of nurse plants (100% survival). In seven of seven comparisons California sagebrush biomass was lower when sown with seeds of nurse plants (0-1 g/m2) than when sown without seeds of nurse plants (5 g/m2). In three 0.75 m2 plots California sagebrush seeds were sown, while in 18 plots a mixture of California sagebrush and succulent lupine Lupinus succulentus or rose clover Trifolium hirtum seeds were sown. Plant survival was recorded in May 1994 following which all plants were harvested and dried to calculate their biomass.
