Protocols

NDFF aims to improve and standardize how natural data is obtained by implementing established protocols: standardized counting methods. This ensures that observations are collected in a unified manner. By working with standardized counting, data can be compared, both within a year and from year to year. This results in a clear picture based on the observations.

Example: participants of urban bird monitoring program MUS count the number of birds they hear and see three times in the spring. This is carried out at 10 standardized spots in a certain postal code area. Counting takes place for exactly 5 minutes on each spot. Postal code areas can now be compared and the development of bird population levels can be tracked over several years.

Observations made according to an established protocol are recognizable as such in the NDFF.

This overview shows observations per protocol from the last 5 years.

Zero observations

When a certain species is not seen or heard, these observations are called ‘zero observations’. The absence of observations of a species is just as valuable as regular observations. Zero observations that are made according to protocol are validated and entered in the NDFF. If zero observations have been made without following protocol, these are deemed unreliable and are not entered in the NDFF.

Quality Assurance Committee

The Quality Assurance Committee develops protocols, which includes testing these on a number of standards:

Has the method been clearly described?
Has the method for processing data before inclusion in the NDFF been clearly described?
Which standards apply to the observers who use this protocol?
How much time do observers spend on observations?
Does the method provide data about the presence and absence of species, or also specific numbers?

ANLb protocols
A number of protocols are designated for the Agricultural Nature and Landscape Management (ANLb). These can be found here.
