Glow-worm survey efforts in the Benelux

Firefly meeting 21-24 June 2007 - Parque Biológico de Gaia

glow worm survey in the benelux
Glow-worm Survey in the Benelux
  • How it all started: 1997
  • Anecdotic data suggest decrease in number and size in British populations from 1950
  • Start of glow-worm survey with help of general public and volunteers
  • Also rumours of decline from the Netherlands, Denmark, Switzerland, France, Germany, other parts of Europe... sometimes leading into surveys
  • Suggestion to start similar project for Belgium: thanks to John Tyler and Robin Scagell

Glow-worm Survey in the Benelux

In spite of:

  • high conspicuousness: bioluminescent displays
  • suitability for inventories

no survey efforts were ever done and knowledge of actual distribution of our regional species stayed fragmentary

Firefly meeting 2007 - Parque Biológico de Gaia

Goals:

  • gather and mapping of old distribution data
  • inform general public about glow-worms
  • get data from general public about old sightings or encourage them to send data about new finding places (e.g. garden): store data for updated distribution atlas
  • maximise knowledge about ecology, habitat requirements, distribution and possible threats (light pollution, habitat reduction, fragmentation, agricultural intensity + pesticides, drainage, acidification, ...)

Glow-worm Survey in the Benelux

Method:

  • providing information about species + project
  • interviews on the radio, in magazines and newspapers
  • doing workshops and talks
  • Contact and help from nature organisations, wildlife mailing lists, etc.
  • website:

  • providing standardised forms:

Glow-worm Survey in the Benelux

Major problems:

  • time: getting data into database and maps: expertise at INBO
  • Belgium is a complex country

Glow-worm Survey in the Benelux

Belgium is a complex country:

Federal state with 3 main regions: Flanders – Walloon - Brussels

Aim: get data from both regions and even from the Netherlands and Luxembourg ... this with and without success

Major problems:

  • time: getting data into database and maps: expertise at INBO
  • Belgium is a complex country

→ getting data is no problem: enough interest and response: about 20-40 new sightings each year

Future aims:

  • first actualised distribution maps
  • continued efforts to make glow-worms known by the public
  • efforts to set-up a glow-worm “workgroup” of volunteers and enthusiasts

set up for a portuguese firefly survey

Set-up for a Portuguese Firefly survey

How it all started: a mail 30 June 2005

  • Gonçalo Appleton Figueira: idea of starting up a survey with help from National Geographic Portugal
  • Also John Tyler, John Day, Michael Geisthardt were asked to join
  • Mails about Phosphaenopterus metzneri, info about species, questions about survey forms, how to set-up an inventory, etc.
  • Help with set-up of inquiry forms and species identification tables

Firefly trip : 25 June - July 2006

  • Visit 5 national parks (PN Arrábida, São Mamede, Estrela, Montesinho, Peneda-Gerês)
  • show standardised methods + method for Phosphaenus
  • Test inquiry forms
  • look for fireflies and glow-worms, focus on Phosphaenus and Phosphaenopterus
  • First contacts with Parque Biológico de Gaia

  • Major interest in organising Firefly meeting 2007
  • Participate in Firefly survey for Portugal

First visit and discussions with Dir. Nuno Gomes Oliveira about logistic set-up and possibilities for a survey:

25-29 May 2007

Logistic set-up and possibilities for a survey: results

A project of this importance needs the support of one or several institutes or (non-profit) organisations:

  • Credibility
  • Material
  • Manpower:
    • Secretary (answering of telephone calls and e-mails)
    • Institute(s) to process even small (initial) costs and to apply for subsidies
    • Reknown scientific institute(s)/person(s) :
      • knowhow about methodology for standardised inventory
      • Help with data storage and processing

Parque Biológico might provide some support here :

Interest for the study and conservation of fireflies

National inquiery about presence of fireflies in 2003

Project “Pirilampos de Portugal” could be launched in March 2008:

  • Logistic coordination: Parque Biológico de Gaia (secretary, webpage, printing and distribution of information, collection and storage of data, etc.)
  • Scientific coordination: Raphael De Cock, J. Grosso-Silva (methodologic support)
  • Coordination of excursions in Portugal: Gonçalo Appleton Figueira, Parque de Gaia ?
  • Scientific collaboration considered necessary: e.g. CIBIO (Centro de Investigação em Biodiversidade e Genética, Universidade do Porto), PhD. José Manuel Grosso-Silva, Dr. Michael Geisthardt (taxonomy)
  • Collaboration of several wildlife associations: e.g. NPEPVS (Núcleo Português de Estudo e Protecção da Vida Selvagem) to mobilise volunteers and for fundraising for material supports.
  • Inform and invite schools, National Corps of Scouts (Corpo Nacional de Escutas - CNE), Nature Parks and other protected areas, City councils and other entities to help us with a national census of fireflies

Proposal for 2-way approach:

1. National census: General public

2. Census within protected areas or focused on particular (rare) species:

 Night excursions in chosen routes

Firefly meeting 2007 - Parque Biológico de Gaia

  • National census:

 General public

    • providing info through internet, guide, media
    • request to send observations (e.g. done within gardens, parks, evening walks, weekend holidays, etc.)
    • minimal info required: date, location, species/species-group, number(class) (extra’s if possible: gender/stage, habitat, conditions: weather, light pollution, etc.)

Firefly meeting 2007 - Parque Biológico de Gaia

2. Census within protected areas or focused on particular (rare) species:

 Night excursions in chosen routes

  • Well-planned excursions to beforehand chosen walking routes “transects” (max 2 km) within protected, isolated or otherwise interesting areas
  • At least 2 persons /transect: e.g. volunteers lead by a specialist and/or local guide
  • Several visits a year: at least 3 times (April – end July)
  • Each year another set of transects within a NP or in a new selection of NPs and revisit after 5 years for monitoring
  • Also specialists of other species group could join to detect new populations in the meanwhile: bats, night birds, grasshoppers, amphibians, etc..
  • Data collected: date, species, number(class), gender/stage,+ specimen collection for possible new species, detailed mapping of findings, description of conditions (weather, light pollution, etc.), habitats and behaviour
