Inventories of biodiversity on the territory of the Perennial Observatory of the Environment: 5 lots

LOT-0001
Avifaunal Inventories.
CFS has been conducting a study of local populations of common birds since 2008. Andra has applied the methodology of the national programme for the Temporal Monitoring of Common Birds (STOC) developed by the National Museum of Natural History (MNHN) in order to have indices describing the evolution of populations at the local level and allowing comparison at various geographical scales up to the national level. STOCCapture: aims to study variations in two of the most important demographic parameters: adult survival and reproductive success; STOCEPS (Simple Spot Sampling): designed to assess spatial and temporal variations in the abundance index of breeding populations of common birds. It is based on listening points. In addition, Andra monitors the populations of protected bird species, including the black stork, the red kite and the black kite. This follow-up consists of carrying out routes to contact individuals in activity and also possible cantonments on the territory.

LOT-0002
Herpetofaunal Inventories.
Amphibian monitoring: several monitoring sessions are required according to the protocols defined by the National Museum of Natural History, which also make it possible to identify remarkable or protected species: 1 amphibian abundance monitoring protocol: egg-laying, juveniles, adults 2 amphibian population dynamics monitoring protocol, carried out by counting individuals on 3 amphibian barriers (on roads).
Monitoring of reptile communities: This monitoring applies the POPReptiles 2 protocol defined by the Herpetological Society of France (SHF), for which a survey is carried out under cover (plate set up by the operator) associated with visual searches during plate surveys.

LOT-0003
description of habitats and floristic inventories.
For this batch, 4 protocols will be carried out: it is requested to renew the monitoring of flowering plants (SPAF) according to the VigieFlore protocol of the National Museum of Natural History on the 13 grids already monitored since 2010. These meshes are each composed of 8 observation points, using metal plates buried at a depth of about 40 cm. Remarkable flora monitoring: Remarkable inventory of species (protection status, invasive species, etc.) on plots that have already been located. Inventory of aquatic flora along predefined sections. Inventory of flora on forest plots.

Entomological Inventories.
-monitoring of lepidoptera For this monitoring, the STERF protocol (Temporal Monitoring of the Rhopalocera of France) will be applied, the latter is part of the more general framework of the biodiversity observatory VigieNature, a program led by the Department of Ecology of the Muséum National d'Histoire Naturelle (Paris). (STERF, see http://vigienature.mnhn.fr/page/suivitemporeldesrhopaloceresdefrance). Monitoring of Diptera Syrphidae: For this monitoring, the "SyrphtheNet" Protocol (StN) proposed by Syrphys AgroEnvironnement and ENSAT of Toulouse will be applied. Monitoring of carabidae and saproxylic beetles: Two inventory methods will be implemented: passive trapping using Barber traps (carabidae) and interception traps (saproxylic) accompanied by a visual search protocol.
-Odonate Monitoring: The monitoring of odonates will follow the protocol of the Temporal Monitoring of Dragonflies (STELI, https://steli.mnhn.fr/sites/default/files/docs_steli/block_pdf/Steli_protocole%20occupancy.pdf). This is a sight search protocol.

LOT-0005
Surveys and monitoring of bats.
The protocols for monitoring bats developed by the ONF and the Muséum National Histoire Naturelle are as follows: "Listening sessions" protocol: a first session in April, and before the end of May (corresponding to spring transits); the second during the months of June and July (refers to the rearing period of the young); the last one in August and September (mating and post-nuptial transit periods). Vigiechiro protocol by "fixed station", and TADARIDA software: A new protocol called "Fixed station" began in 2014 and is now mainly used by the National Museum of Natural History (MNHN). This protocol is based on full-night recordings (Bas et al., 2020). The raw files (WAC or WAV) generated by these recordings are automatically analysed by the TADARIDA identification software developed by the MNHN since 2017 (Bas et al., 2017 and Barré et al., 2019).
