As a first step, the CPS recommends to proceed with in-situ conservation in the natural habitat of the species. In some cases, very simple protection and site management measures (e.g. mowing, shrub control, water table regulation, etc.) are sufficient to bring back populations to an acceptable level.
If populations remain at critical levels, ex-situ conservation measures might be required (cultuvation and propagation in botanical gardens). Seed or plants obtained in gardens will be used to reinforce existing natural populations or to reintroduce the species in sites from which they have disappeared . These measures have to be implemented following strict rules and must be authorized by the authority of the canton.

Thorough knowledge of the species biology, ecology, distribution and threats are required in order to ensure successful conservation projects.
-> see Data sheets for practical conservation
An action plan with a description of each step of the process is often necessary: habitat description with planned measures, timetable, budget, funding and responsibilities.

The population(s) of threatened species must be periodically monitored. When conservation measures have been implemented, their impact has to be recorded over several years.

There are numerous on-going plant conservation projects in Switzerland with active involvement of the Cantonal Offices for Nature Conservation, botanical gardens, and academic institutions. The CPS Database provides both an update on on-going activities and information on similar projects and lessons learned.
