Log collated index plot
This chart shows the index of abundance (LCI = Log Collated Index) over time. It shows fluctuations in
populations from year to year, and is scaled so that the average index over the whole series is equal to 2
(horizontal line). For greater detail about how this index is derived, click on the green question mark above.
Trend description :
The Large Copper was last recorded on the Woodwalton Fen transect in 1989 after which time it became extinct at the site.
This map shows the distribution between 1995 and 2016. Data is derived from the Butterflies for the New Millenium dataset via the NBN Gateway
This chart shows the average number of butterflies seen on transects between Arpil and October across all sites (fitted values from a Generalised Additive Model). The blue line gives average counts over the full BMS series (1976 to date) and the red line gives the average for the last year.
This map shows symbols for the mean abundance at transect sites, with the colour of the symbol reflecting the level of abundance. Means are over all years. Grey background squares are the occupied cells as shown by the Butterflies for the New Millenium over the previous ten year period.
In total, Large Copper has been recorded from 14 transects in the Butterfly Monitoring Scheme. Of these, annual indices of abundance have been calculated from 1 sites, with an average index of 0 individuals per site.
For 0 of these sites, Large Copper has been recorded well enough to calculate annual indices of abundance in more years, allowing trends to be calculated.
In 2004, 0 individuals were recorded from 0 sites, producing annual indices at 0 of these.
This map shows the trend in abundance at particular transect sites for which data has been received within the last five years. Trends (increasing, declining or stable) are assessed at sites where the species has more than five years of annual index data. Use the option boxes below to view plots for individual sites.
