What the buyer is looking for
The aim of this research is to evaluate the effectiveness of nature restoration measures carried out, using a standardised methodology. The Red Table with Green Tip method uses Red Table species as a measure of success. The idea is to apply this method again, creating a unique time series of 20 to 30 years in which the effects of measures have been closely monitored. The results of the study should lead to: • A summary table showing the effectiveness of the different measures per species (group) and over time; • Understanding the management and policy for which species a measure is effective; • Understanding what timeframe results of a measure can be expected; • Understanding after how many years a measure should be repeated. The maximum available budget for this assignment is € 289,256.20 excluding VAT and € 350,000, - including VAT.
