PUBLISHED: 02. 10. 2018

European Researchers Night has been organized on every last September’s Friday since 2005. This year, on September 28, the event took place also in the Botanical Garden of the University of Latvia where LIFE Peat restore team was likewise invited. Cultural heritage was chosen as this year’s topic, which includes also traditional land usage. To raise public awareness of the impact to environment after land management, rain erosion was discussed in the Mire laboratory.

A simple experiment using four different models showed soil depletion intensity in agricultural land and peat extraction field and compared to forest soil and natural bog. After the experiment, every participant agreed that sustainable land management must include not only efficient agriculture, but also nature conservation.

In the Mire laboratory, another activity was organized to demonstrate effect of different chemical dyes to Sphagnum moss microscopic samples. Methylene blue, malachite green and Congo red stains were visually approved as the most suitable pigments for hyaline cell research.

The Botanical Garden participated already the ninth time in the European Researchers Night, receiving nearly 400 visitors this year, mostly pupils and families with children. Historical guided tour celebrating the 90th anniversary of Glass houses, explanation of nutrient and water uptake in plants, flower origami, coffee painting on Ficus leaves and plaster cast of fruits and seeds were offered to every visitor.
