The Importance Of Butterfly Decline In The Byre
Butterflies, like many insects across the UK have undeniable importance to the ecosystem. Maintaining butterfly populations has become a priority across the globe as anthropogenic activities increase to threaten butterfly species. One such species under threat in the UK is the Duke of Burgundy. Decline in flagship species over recent years has led to a review of the biodiversity action plans and the importance they have across the globe. This POSTnote examines the risks of butterfly decline for the UK, exploring the anthropogenic impacts on the Duke of Burgundy and assessing relevant strategies to better conservation.

An estimated 24% colony loss per decade and 98% decline in woodland sites (Oates, 1985) puts this species under serious threat and allocated high priority in the conservation action plan (Table 1). The distribution of Hamaeris Lucina is small, with key strongholds in central and southern England and isolated hotspots in the east midlands, North Yorkshire and around Morecambe Bay. In the 1998 ‘Species Action Plan’ broad objectives were outlined: 1) Halt decline, 2) maintain viable networks of populations throughout its current range and 3) long term objective to restore its 1950 range, particularly in its woodland habitat. Climate change has sent the Monarch butterfly to extinction and after suffering ‘Britain’s Worst Summer’ in 2009. (ref) The Duke of Burgundy teeters on the …show more content…
• Results from an experiment done on butterfly species Junania coenia supports previous investigations indicating that higher dispersal through corridors promotes increased genetic variability (Wells et al., 2009).
• Corridors linking grassland and woodland suitable for Duke of Burgundy habitat increases population abundance and prevents extinction.
THE IMPORTANCE OF CONSERVING OUR BUTTERFLY SPECIES
Recognised by the government as key indicators of biodiversity butterflies are essential to almost every biome they occupy (R, 2015). Not only do they act as pollinators and food in food chains, they also have intrinsic value to the human population.
• Butterflies are biological indicators of a healthy environment
• Areas rich in butterfly species often promote other species richness. This adds up to a range of benefits including pollination and control of pests.
• Butterflies are used as model organisms to scientists and ecologists, for centuries investigating various fields of biological
