There was an increasing interest in bats in Norway during the 1990’s, NIFF was established as a result this in May 1997. First as a Norwegian organization, from May 2004 we became an international organization covering the five Nordic countries (Norway, Sweden, Denmark, Finland, Iceland).

The organizations objectives are to:

  • map and monitor bat populations,
  • work with measures enhancing the protection of bats and their environment,
  • distribute information to the general public and management authorities.

Today, over 200 people are members of NIFF. Most of these have joined one of our 7 regional bat groups. Many members had prior to their membership little interest in nature and conservation, and become members solely because of their genuine interest in bats. Around 1/4 of our members are school pupils and another quarter are house owners with a bat colony at home, wishing to learn more about their tenant. However, NIFF also includes scientists and others who work with these bats on a daily basis.
          If you are interested in working with bats, you may join a bat group, or contact with one of our contact persons. Membership of a bat group includes a membership of NIFF.




NIFF is a democratic membership orga­ni­zation. Anyone interested in bats may become a member of our organization. This does require that you accept NIFF’s Articles, support the organizations work, and pay the membership fee required. Membership follows the calendar year, and stays until you notify the organization in writing. Members younger than 11 years are not excepted.[1].
      All members are updated on activities and trips through our newsletter Lešrblaka Express. All new members also receive the 36-page booklet Vi studerer flaggermus (How to study bats). Most of them also receive the membership bulletin Gudnjoloddi and new brochures. Type of membership decides what material the members receive.

God parents
Families who are lucky to host a bat colony in their house might become a member. There is no membership fee. However, they are required to give a report on the status of the colony every year. They may also note when the colony arrives or departs for the season. Especially important is annual count of emerging bats. This way the population may be monitored through many years. An own brochure has been made for the godparents.
      The godparent receive the local bat group newsletter, as well as the newsletter Husgjesten (=the House Guest) or Gruvetrollet (=the Cave Troll), depending on if their colony is using their site during summer or winter.
