Question
To ask the Scottish Government, further to the answers to questions S5W-20621 and S5W-26208 by Roseanna Cunningham on 8 January and 22 November 2019, whether it will make an assessment of the implications for its policies of the reported greater success rate of hen harrier nests on non-RSPB nature reserves compared to RSPB nature reserves.
Answer
The Scottish Government does not believe it is necessary to make a specific assessment of the implications of its policies of the reported greater success rate of hen harrier nests on non-RSPB nature reserves compared to RSPB nature reserves.
Hen harrier success rates are dependent on a number of different factors, as set out in the response to PQs S5W-20621 and S5W-26208. A significant reason for the lower productivity on RSPB reserves is because several are on Orkney where there is a high level of polygyny (males having 2-3 females). As males cannot provision up to 3 nests, failure of the 2nd & 3rd females is regular with fewer young raised (than a monogamous pair) even if they are successful.
