計畫資料

State and EU regulations require Member States to monitor, track, and assess various species of terrestrial mammals. Periodically, it is necessary to update reports and Red Lists, which are essential for defining appropriate management measures to protect and promote biodiversity in our country. In this context, the project developed by SECEM together with TRAGSATEC (2024–2025) was launched, in which a Terrestrial Mammal Monitoring plan (MOMAT) was designed. Its objective is to gather information on most mammal species that currently lack specific monitoring programs. At present, the MOMAT project operates thanks to volunteer participation. The data collected help improve knowledge about the species included both in the annexes of the Habitats Directive and in the EU Regulation on invasive alien species. Aditonally, 338 records have been provided by the platform for the collection of dietary data (pellets and latrines) within the Common Small Mammal Monitoring program SEMICE (www.semice.org). All the information generated will contribute to future updates of the Atlas and Red Book of Terrestrial Mammals of Spain, facilitating a better understanding of our fauna and supporting more effective decision-making in conservation.

取樣方法

Micromammal presence was assessed through the analysis of owl pellets, mainly from barn owls and other nocturnal raptors. Pellets were collected at roosting and nesting sites, with up to 25 pellets analysed per site when available. Prey remains, primarily skulls and mandibles, were identified to species using osteological criteria and SECEM reference materials, and data were managed via the SEMICE platform. This non-invasive approach enables detection of many micromammal species for which other survey methods are limited.

方法步驟描述:

1. Micromammal presence data were obtained through the analysis of pellets produced primarily by barn owls (Tyto alba), as well as other nocturnal raptors including Strix aluco, Asio otus, Bubo bubo and Athene noctua. Pellets were collected at known or potential roosting and nesting sites. When available, at least 25 pellets per roost were analysed; if fewer were present, all available pellets were processed. Prey remains contained within the pellets, mainly skulls and mandibles, were identified to species level using established osteological criteria. Identification was supported by reference manuals and digital tools developed by SECEM, and data were centrally managed using the SEMICE platform. This non-invasive method allows detection of a broad range of micromammal species for which alternative census methods are limited or unavailable.
