Park Grass Experiment

Subtopic: Purpose and Location
– Study effect of fertilizers and manures on hay yields
– Located at Rothamsted Research in Hertfordshire, England
– Initiated in 1856
– One of the longest-running experiments in modern science
– Continually monitored since inception

Subtopic: Impact and Significance
– Resource for studying natural selection and biodiversity
– Treatments affect botanical make-up and ecology of the field
– Field showcases a variety of flowers and grasses
– Demonstrates threats to plant biodiversity from long term changes
– Shows relationship between plant species richness, biomass, and pH

Subtopic: Findings and Discoveries
– Competition between plants intensifies effects of climatic variation
– Local evolutionary changes under different selection pressures observed
– Archive of soil and hay samples used to track atmospheric pollution history
– Demonstrated underestimation of threats to plant biodiversity by conventional field trials
– Provided insights into how plant species richness, biomass, and pH are interconnected

Subtopic: Academic Contribution
– Study published in the Journal of Ecology
– Silvertown et al. (2006) detailed the experiment’s contributions to ecology
