Southern small white butterflies conquer Dutch province


This video from Switzerland is about a southern white butterfly.

On Sunday, September 27th, 2015 the first ever southern small white butterfly in the Netherlands was observed at the Fort Sint Pieter in Maastricht in Limburg province.

Since that time, now, in October 2016, 105 southern small whites have been observed, at various places in the south of Limburg province.

This species used to live only high up rocky mountains, in, eg, Switzerland, Morocco.

Recently, to their surprise, biologists found it had extended its biotope to rock gardens around Zürich, and was common there. There are many rock gardens in many countries, making it possible for the species to spread further.

For the, often subtle, differences between white butterfly species, see here.

Natterjack toads benefit of bison in Maashorst

21 August 2016 – In the North Brabant province nature reserve Maashorst nature is in full swing. Recently European bison were introduced there. Along with Exmoor ponies and Tauros cattle they graze the grasslands, heaths and forests of the Maashorst. With their grazing and digging they provide spaces for other species such as the natterjack toad.

This 2014 Dutch video is about Tauros cattle: an attempt to breed the extinct aurochs back.
