Moor Frog survey

Ecobio Oy carries out high-quality moor frog surveys across Finland.

Why is a moor frog survey needed?

The moor frog (Rana arvalis) is a species protected under the EU Habitats Directive, which prohibits the destruction or deterioration of its breeding and resting sites.

In land use projects, zoning, and construction, a moor frog survey is often essential to ensure legal compliance and safeguard biodiversity.

How are moor frog surveys carried out?

The aim of a moor frog survey is to identify the presence of the species as well as its breeding and resting sites within the project area.

Ecobio manages the entire process:

• Field surveys and/or eDNA sampling
• A clear report for the authorities
• Practical recommendations for project progress

When is a moor frog survey conducted?

For identifying the breeding and resting sites of the moor frog, the best observation period is during the spring breeding season, when males can be recognized by their characteristic mating calls.

The timing of the surveys varies regionally depending on the progress of spring and weather conditions. Typically, the surveys are carried out in April and May.

The survey window is quite short, since males call only for a few weeks in spring. Fieldwork must be scheduled within this period, when the frogs are actively displaying. The survey should be ordered well in advance to avoid project delays caused by the short survey season.

Ecobio can also use eDNA sampling to study the occurrence of moor frogs, which enables surveys to be conducted outside the mating season.

In what situations or projects is a moor frog survey required?

A moor frog survey is required especially in the following cases:

• In connection with zoning and construction
• Infrastructure projects (roads, railways, energy networks)
• Development of industrial and residential areas
• Near water bodies and wetlands
