Emergence and survival of seedlings of lotus or narrowleaftrefoil (Lotis tenuis WaldsL) were monitored in 4 grazed pastures dominated by tall fescue (Festuca arundinacea Schreb.) for 2 successive years. The objective was to detect patterns and environmental conditions promoting successful seedling establishment of lotus. Emergence followed a seasonal pattern each year, with most emergence occurring towards the end of winter. Seedling emergence occurred mainly in heavily grazed sites which occupied 45 to 90% of each pasture. Seedling emergence was greatest, but seedling survival was poorest in the wettest year. Competition resulting fmm climatic conditions favoring growth of established pasture plants was detrimental to establishment of lotus seedlings. In contrast, heavily grazed areas provided microsites that enhanced survival of new recruits during the spring growing season. Dense seedling stands emerging on feces were overcrowded and suffered the highest mortality, thus, they contributed little to recruitment of lotus. However, dispersal of lotus was enhanced by the presence of seeds in livestock feces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
