Staff

Leif Yngve Gjerde

Founder and partner of Naturopa Consultancies. His responsibilities are administration, marketing and project management.

Responsible for the Environmental Impact Assessments, monitoring and surveying, with especial knowledge on plants, insects (grasshoppers), amphibians, birds and mammals (bats).

Familiar with the legal aspects of wildlife law in Norway, Sweden and Denmark. Including the Habitats Directive (Council directive on the conservation of natural habitats and of wild fauna and flora), the Birds´ Directive (Council Directive on the Conservation of wild birds)

Working experience - insects
Worked with mapping grasshoppers, and currently working on a popular booklet about Norwegian grasshoppers.

Working experience - amphibians
Worked with metapopulation ecology on amphibians since 1988 in the Øyeren delta. Organized twice the Nordic Herpetological Symposium, last at Lund University. Mapping and studying amphibians in Norway, Sweden and Denmark. Worked especially on Rana dalmatina, R. arvalis, R. temporaria, Triturus cristatus and T. vulgaris. In the 1990´s worked on a research project at Oslo University and Odense University where he developed a method for distinguishing the egg clusters of the brown frogs (R. arvalis, R. temporaria and R. dalmatina). Sectretary and web master of the Nordic Fieldherpetologcal Forum, and leader of the Norwegian Fieldherpetological Forum.

Working experience - bats
Gjerde has worked professionally with bats since 1993. During these
20 years he has been occupied between 30% and full time with bats on an annual basis. This includes fieldwork with survey and monitoring, atlas studies and mitigation projects. Bats have been identified passively by ultrasound detectors or actively by catching and handling bats individuals by mistnett, harp traps or from buildings (including over 300 churches).
     He has almost 20 years of experience of bat identification with the use of ultrasound devices, which include the use of heterodyne, time expansion and frequency division. Thus having experience with “live time” detectors produced by Pettersson, Wildlife Acoustics and Titley Scientific. However, during the past 7 years, also with passive detectors functioning as logging devices.
    
In Denmark he has been active with environmental impact studies (VVM) in Randers, Varde, Assens and Nyborg municipalities. This include projects on wind turbines, roads and golf courts. An ongoing migration study is being carried out on Skagen and Fyn. Furthermore, a fall study on Vespertilio murinus in Aalborg and Aarhus has, and still is, being carried out. Surveying hibernacula in Hanstholm, Hirtshals and Skagen, including visiting Thingbæk kalkminer for annual counts during a period of 6-7 years.

Working experience - birds
Been working actively with birds since 1977. Most focus on breeding birds, and started the Norwegian Nest Record Scheme. Was a contact person for project Eagle Owl in Oslo and the surrounding regions, carrying out fieldwork confirming reestablished territories. Also doing fieldwork for Project Peregrine falcon. Have been a licenced bird ringer for several years.

Lea Likozar

Partner of Naturopa Consultancies. Her responsibilities are Environmental Impact Assessments, monitoring and surveying, with especial knowledge on bats. Likozar is at present suspended.

Familiar with the legal aspects of wildlife law in Europe, including the Habitats Directive (Council directive on the conservation of natural habitats and of wild fauna and flora), the Birds´ Directive (Council Directive on the Conservation of wild birds) and the convention on the protection of the Alps.

Working qualifications - bats

She has been working with bats for the past 10 years (from 2008). During this time she has attended 12 student research camps (97 days of training). This includes 84 nights of mist netting, catching between 0 and 100 bats per night from a total of 23 species.

      Furthermore, a total of 40 different caves have been surveyed, and monitoring additional 16 caves/mines.

     She has assisted at different projects carried out by the Centre for Cartography of Fauna and Flora, the Slovenian Association for Bat Research and Conservation and the Biotechnical faculty at the University of Ljubljana.

      She has extensive experience with the use of ultrasound detectors.

Environmental Impact Assessments

Research is not enough
Typical for many projects where environmental impact assessments are required, is to make a hypothetic assessment based on existing information/knowledge such as game maps, local organizations, databases and literature. In most cases this is not sufficient since it gives an incomplete and false impression of the area.

An assessment should include:

  1. Research (existing knowledge)
  2. Surveying (fieldwork)
  3. Mitigation (measures to reduce the negative impacts)
  4. Monitoring (make sure the mitigation measures work)

A complete assessment always require fieldwork!
The general requirement is that fieldwork is always necessary to get the whole and complete picture of the areas´ flora and fauna. A good investigation requires 2-3 years of fieldwork. However, this is usually unrealistic unless the work is initiated from the early phases of the project.
Regardless, an environmental impact assessment that does not include all seasons, cannot be defended as professional. It will always take a full season. For many groups of plants and animals this is a 12 month period. For amphibians this is April to September (Norway), and bats from March to September.
Naturopa Consultancies will always have a preinvestigation where the area is visited, and the need for further projects assessed. This is always necessary, and will often reveal that all projects (listed below), is not necessary.

It is important that environmental impact assessments lead to solutions which protects the nature in a sustainable way, and simuntaniously leads to constructive and practical solutions. Many solutions are simple and little costly.

Amphibians

We have extensive experience in amphibians (see working experience below). In Norway fieldwork starts in April and ends in September. The following fieldwork is recommended:

  1. Potential breeding and hibernation sites
  2. Breeding ponds (frogs/toads in April/May, newts in April - June)
  3. Movements to and from breeding ponds (frogs/toads in April/May, newts in April and June-August)

Bats

There are registered 13 bats species in Norway (1/4 of our mammal species), and 7 bat species are redlisted. The season starts in March and ends in October, depending on where you are.
Migration is especially i important in coastal areas from Tønsberg to Bergen, south and south-eastern Sweden and all of Denmark.
During summer the bats are distributed differently through early, mid and late summer. This is due to different needs and thus use of the area. The following projects may be of use:

  1. Spring (1 April-15 June) - migratory species with only use of passive detectors.
  2. Early summer (10 May to 21 June) - Mapping the use of the area during a period the bats usually use localities of high insect production (e.g. waterways, lakes, ponds).
  3. Mid summer (July to 10 August) - Mapping the use of the area during a period when they are more evenly distributed in the landscape.
  4. Late summer (10 - 31 August) - Mapping the use of the area during a period the young have learned to fly, and the mating season has started.
  5. Fall migration (1 August - 20 October) - migratory species with only use of passive detectors.
  6. Hibernation sites (November - February) - inspection of mines and caves where the entrance area or mountain (tunnels) is affected.

Spring and fall migration is only required in certain areas. Hibernation investigations is only required where the entrance or mountain itself is effected.
