Toolkit for Ecosystem Service
Site-Based Assessment

Request Form

Understanding the impacts on ecosystem services of actual and potential changes in state at individual sites is important for promoting better planning decisions to support both biodiversity conservation and ecosystem service delivery. Until now this approach has been relatively little used because it has been assumed that ecosystem services are technically difficult and expensive to measure.

This toolkit is designed to overcome this obstacle by providing practical guidance on how to identify which services may be significant at a site of interest, what data are needed to measure them, what methods or sources can be used to obtain the data and how to communicate the results.

The toolkit emphasizes the importance of comparing estimates for alternative states of a site (for example, before and after conversion to agriculture) so that decision-makers can assess the net consequences of such a change, and hence the benefits for human well-being that may be lost through the change or gained by conservation.

The toolkit has attempted to find a balance between simplicity and utility of developing convincing information for decision-makers and therefore excludes consideration of some of the more advanced concepts in ecosystem services. This is so that it can be used by non-experts, yet still provide scientifically robust information.

Terms of use - Please read the terms of use, disclaimer and errors and omissions statement here

I accept and agree to be bound by the TESSA terms of use

The compilers of TESSA are collating data derived from its application for meta-analysis, to evaluate at a broad scale the contribution that information on ecosystem services can make to biodiversity conservation. Would you be interested in contributing, potentially as a coauthor, and for your results to be considered for use in this way? If you wish, any data you provide will be made anonymous and not explicit to location or organisation

YES I would like the opportunity for the results of my application of TESSA to be put to wider use

Privacy - BirdLife International will process your data in accordance with the UK Data Protection Act 1998. On occasion we may pass your data onto BirdLife International Partnership organisations.
