Pearl-bordered Fritillary Seminar 2026

On 14 September 2026, Montgomeryshire Wildlife Trust hosted a seminar bringing together conservation practitioners, researchers, volunteers, land managers, environmental NGOs and statutory agencies to explore the challenges and opportunities of conserving the Pearl-bordered Fritillary (Boloria euphrosyne) across Wales, England and Scotland. This page provides access to the presentation recordings and seminar report, creating a lasting resource on the species' ecology, management and recovery, while highlighting current challenges, knowledge gaps and priorities for future conservation action.

Dr Simon Spencer - seminar purpose and context 

Introduction to the Pearl-bordered Fritillary butterfly day seminar held by Montgomeryshire Wildlife Trust on 14th September 2026

MWT Conservation Officer Tammy Stretton and MWT Trustee and Volunteer Tim Ward

What does it take to conserve Pearl-bordered Fritillaries in Montgomeryshire? MWT's Tammy Stretton and Tim Ward explore 25 years of habitat management and monitoring, highlighting the challenges of maintaining connected violet-rich habitat and the lessons learned from Wales’s last remaining strongholds for this threatened butterfly.

Dr Jenny Joy with additional comment from colleague Mike Williams

How does England's largest population of Pearl-bordered Fritillaries survive in the Wyre Forest? Dr Jenny Joy explores two decades of monitoring and habitat management, revealing how connected woodland habitats, adaptive conservation and volunteer-led action are helping this threatened butterfly thrive.

Dr Simon Spencer speaking on behalf of himself and Gareth Eggar of Natural England

Dr Simon Spencer explores the opportunities and challenges of habitat restoration through England's Countryside Stewardship scheme, using lessons from Nantmawr to show why long-term landowner engagement, grazing and landscape-scale habitat connectivity are vital for this threatened butterfly.

What is driving the decline of Dartmoor’s fritillaries? Jenny Plackett explores the management of Pearl-bordered and High Brown Fritillaries on Dartmoor, highlighting innovative habitat restoration trials, emerging threats and new research aimed at reversing long-term population declines.

High Brown Fritillary in the Alun Valley; Paul Dunn, with additional comment from Richard Smith 

How can practical habitat management sustain fritillary populations for decades? Paul Dunn shares lessons from over 30 years of conservation in the Alun Valley, showing how targeted woodland management, grazing and careful monitoring are helping maintain vital breeding habitat for the High Brown Fritillary.

Dr Simon Spencer uses Llanymynech Hill as a case study to demonstrate how successful habitat restoration depends not only on grazing livestock, but on sustaining the skilled graziers, infrastructure and long-term commitment needed to make conservation grazing work.

Myrmica ants as keystone species and Maculinea arion as an indicator of rare niches in UK grassland; Dr Zoe Randle

Dr Zoe Randle explores the hidden relationships between violets, ants and butterflies on Dartmoor, revealing how microclimate, seed dispersal and species interactions shape habitat suitability in a changing climate.

Anthony McCluskey, Butterfly Conservation Manager (Scotland)

Anthony McCluskey explores the species’ encouraging status in Scotland, highlighting the habitats, landscape features and conservation successes that are helping populations persist, expand and even establish new colonies in a changing climate.

Dr Simon Spencer reflects on the big picture for Pearl-bordered Fritillary butterflies in Wales, exploring four decades of successes, setbacks and lessons learned in the effort to restore and reconnect populations of this threatened butterfly.

Recording of the open discussion session at the end of the PBF Seminar held by MWT on 14th September 2026.

The open discussion largely centred round the different techniques which have been or could be used to create and manage habitat, with and without grazing animals.
