2 Contract Details

2.1

Title

Desk based review of the methods used to assess the effects of windfarms on different bird species

2.2

Description of the goods or services required

SWBSG require the successful contractor to review the methodology of data collection for breeding birds at windfarms and to present their findings as to how these data could be used for further analysis.

Crucially, the review should present the opportunities and limitations for further analysis of

these data and their ability to be used to answer specific questions related to the effects of

windfarms on birds which are included in the SWBSG research programme. The review should

include consideration of the aspects raised below and any other considerations identified as

being relevant by the successful contractor (these should be stated in the tender return):

1. Territories vs individual registrations: how do abundance estimates vary depending on

whether individual registrations or territories are used? How objective is the

interpretation of territories from the individual surveys?

2. Review any studies that have been undertaken to calibrate the Brown and Shepherd

methodology, and conclude whether the available calibration includes sufficient

information for species and habitat types typical of windfarm locations.

Detecting change in abundance (either territories or individual registrations): can

estimates of precision be calculated or inferred, and if so how do these vary according

to the factors listed above? Is it possible to quantify the Minimum Detectable Change

(MDC) which could be detected for individual species/sites, or the degree of replication

which would be needed to achieve a particular level of precision, and the statistical

power with which to assess changes in abundance, using worked examples as

appropriate?

4. Accuracy of spatial recording: can the accuracy and precision of spatial recording be

quantified? If so, quantify these specifically or generalise where this is not possible.

5. The review should consider whether Bayesian techniques are applicable, and if so

describe the opportunities/limitations of how these techniques could be applied.

In addition to the review outlined in 1-5 above, SWBSG require the successful contractor to

review the methodology of data collection for flight activity and present their findings as to

how these data could be used for further analysis, for example in addition to estimates of

collision risk. Crucially, the review should present the opportunities and limitations for further

analysis of these data and their ability to be used to answer specific questions related to the

effects of windfarms on birds which are included in the SWBSG research programme. The

review should include consideration of the aspects raised below and any other considerations

identified as being relevant by the successful contractor (these should be stated in the tender

return):

1. Detecting change in flight activity: can estimates of precision be calculated or inferred,

and if so how do these vary according to the factors listed above? Is it possible to

quantify the Minimum Detectable Change (MDC) which could be detected for

individual species/sites, or the degree of replication which would be needed to achieve

a particular level of precision?

2. What methods are available for summarising flight activity data spatially? Provide a

review of approaches using histogram and kernel density estimate techniques, and any

other suitable methods, including opportunities/limitations of how these techniques

could be applied.

3. Accuracy of spatial recording: can the accuracy and precision of spatial recording be

quantified? If so, quantify these specifically or generalise where this is not possible.

4. The review should consider whether Bayesian techniques are applicable, and if so

describe the opportunities/limitations of how these techniques could be applied.
