What is a nature reserve?
It is a unique natural space protected by regulations specific to it. National reserves are classified as such by ministerial decree.

A nature reserve has three main missions:
To protect fauna and flora by learning more about them, by tracking animal and plant populations and enforcing regulations.
To manage natural environments so they maintain favourable conditions for biodiversity, either by action or inaction.
To share its natural heritage with everyone.

La Bassée is home to a large number of species. Some of them are common. Others are rarer and/or endangered. These are referred to as “heritage species”.
Among these rare/endangered species, the Scientific Council has identified several for which the nature reserve has a responsibility to preserve them.
