Log collated index plot

blank LCI plot - no data available

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 :
This butterfly is recorded on very few BMS transects and data are insufficient to identify any trends.

This map shows the distribution between 1995 and 2016. Data is derived from the Butterflies for the New Millenium dataset via the NBN Gateway

Phenology plot

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.

Abundance

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.


Coverage

In total, Mountain Ringlet has been recorded from 74 transects in the Butterfly Monitoring Scheme. Of these, annual indices of abundance have been calculated from 5 sites, with an average index of 0 individuals per site.

For 0 of these sites, Mountain Ringlet has been recorded well enough to calculate annual indices of abundance in more years, allowing trends to be calculated.

In 2016, 23 individuals were recorded from 2 sites, producing annual indices at 1 of these.
