Plot sampling is an ecological and environmental survey method in which discrete, usually regularly or systematically arranged, spatial units (plots or quadrats) of defined size and shape are selected to estimate properties of populations, communities, or habitats. Within each plot, variables such as species presence, abundance, biomass, or structural attributes are measured and then extrapolated to larger areas under assumptions about spatial homogeneity and representativeness. Plot sampling designs may be random, systematic, or stratified, and are chosen to control sampling error, minimize bias, and enable statistically robust estimation of parameters such as density, cover, diversity, or productivity.
Abandoned farmland can be transformed into wildflower-rich grassland habitat without the need for expensive and labor-intensive seeding, a new study by UCL researchers finds.
