Long Meadow Flora Surveys
Fixed survey plots
Four randomly selected locations are surveyed in each of 12 plots, also randomly selected. The aim is to record all species present and assess the proportion of ground covered by:
Forbs (a herbaceous flowering plant that is not a graminoid - or grass)
Grass – split into the “thugs” (Cock’s-foot, False oat-grass and Yorkshire-fog) and the other less-thuggish grasses
Bare ground – measured at the ground surface.
The area covered by the two kinds of grass is an indicator of how well the finer grasses are doing under the management regime. This complements the information on the forbs.
The relative cover for these four groups in 2024 is shown in this interactive map. The species present are shown in the following tables. In these tables the numbers / colours indicate the prevalence of each species present – whether it occurred in 1, 2, 3 or all 4 locations in the surveyed plot.
Hover over a site to see more information on popups. The inner pie chart is the base value from 2024. The outer ring is the latest value.
