I compile concrete projects that have achieved the promotion of one or more endangered insect species through specific measures.The measures should be well described and the success documented by a significant population increase or re-establishment of the endangered species. Priority is given to measures that may (also) be relevant in Central European habitat types. Our framework project is PLAIN.
