RAVON (NL) - Network Ecological Monitoring Reptiles

最新版本 由 Reptile, Amphibian and Fish Conservation Netherlands (RAVON) 發佈於 Nov 14, 2018 Reptile, Amphibian and Fish Conservation Netherlands (RAVON)

The Dutch reptile populations are being monitored intensively within the scope of the Dutch Network Ecological Monitoring (NEM). Since 1994 volunteers, coordinated by RAVON (Reptile, Amphibian and Fish Conservation Netherlands), monitor reptiles on an annual base. All seven indigenous species are monitored on transects that are examined seven times a year. The data are used to monitor population trends and patterns and to support legal reporting obligations, scientific research and policy and conservation related issues. Locality data for GBIF are provided on a 5 x 5 km scale.

Data Records

取樣方法

Transects are visited seven times a year under favourable weatherconditions. All encountered reptiles are counted.

研究範圍 Transects are monitored within a two hour timespan. A transect typically consist of only one habitat type.
品質控管 The raw data are validated by the coordinator. Statistics Netherlands (CBS) runs an extensive control of the monitor data before calculating trends and indices.

方法步驟描述:

  1. Trends and indices are calculated by Statistics Netherlands (CBS) using the TRIM-software package. This dataset summarizes the observations per km2 for each year in an occurrence value per species.
