Description
The ultimate objective of this project is to produce new red lists for the Coleoptera Cerambycidae, Buprestidae, Lucanidae and the Scarabaeidae Cetoninae of Switzerland by the means of the UICN categories and criteria. This project, very ambitious taking into account the number of species and the strong variability of their ecology, is still in the preliminary phase which aims:

to test various trapping methods and to choose which will be finally applied
to develop a protocol of very precise sampling for the future collaborators of the project
to define what falls in the "site concept" for these groups and to choose on this basis those which will have to be prospected (prospective sampling and re-sampling)
to ensure the training of naturalists in the envisaged groups in order to increase the number of potential collaborators.

Data source
The project benefits from all data collected during the last fifteen years in the numerous public (Swiss and foreign museums) or consulted private collections and from all data collected recently within the framework of targeted scientific studies or leisure activities.

Preliminary processing
This phase began in 2001. Here is the summary of the principal activities deployed and the principal results obtained.

2001: was profitable to analyse the data already available in the CSCF database and to draw up the list of target species for future sampling. It also made it possible to gather much information on their ecology and their capturing method and to draw up and test a first field card and to choose a series of sites favourable for future re-sampling.

2002: allowed to compare the effectiveness of various trapping methods of in six chosen sites in 2001. A black combined window trap, a transparent combined window trap, an odorous trap (with tree essence) and an attracting white trap (benzyl acetate) functioned from the beginning of May to the beginning of August in each site. This sampling by fixed traps was supplemented by 5 days of active hunting (visual hunting, beating of branches, crop net hits, reversal of bark...). The principal results obtained are as follows:

active hunting is the most efficient trapping method
the transparent combined window traps, less efficient, is an interesting complementary method
the other methods, definitely less effective, can be abandoned.

2003: five of the six stations studied in 2002 were prospected again by visual hunting and a transparent combined window trap in order to specify the tendencies highlighted the previous year. This year was also used to organise training sessions and excursions for the collaborators of the project.

The principal results obtained confirm the results of the previous year:

active hunting appears to be by far the most effective method under the condition that it is carried out by an experienced or well trained naturalist; two seasons of active hunting are much more effective than only one; a sixth summer session is particularly favourable
only the multiplication of the number of transparent combined window traps could compete with active hunting. Taking into account the disadvantages related to their use, this method can be abandoned.

2004-2005: these two field seasons were used to perfect the sampling protocol by active hunting in six new stations (6 sessions per annum and per station) and to continue the training and recruitment strategy of collaborators which was triggered in previous years.

The precise sampling protocol, the choice, the nature and the number of sites to be prospected in order to reach the initial goal of the project in addition to a detailed budget for the operational phase will be available at the beginning of 2006.
