In a partly EU-funded project, a total of 185 ecox composts have been built in 30 nature reserves in Kalmar, Blekinge and Östergötland counties.

The composts consist of logs from deciduous trees that are dug into the ground and then covered with wood chips.

Under the buried logs, a favorable environment has then been created for the female oxen to lay new larvae.

- Right now we are doing a follow-up of the project and when we examine the composts we find larvae in several places, so it's fun, says Nicklas Jansson.

See in the clip above how to build an ox compost.

On this day, we visit an oxen compost placed in the nature reserve Hästenäs church forest by Lake Yxningen in Åtvidaberg municipality.

Nicklas Jansson and reserve manager Mikael Burgman make a valiant attempt to find some echo larvae under the logs.

See below in the clip how it went:
