HISTORY OF NEST USE NEST DISTURBANCE WHAT WAS SEEN Unknown This nest is considered based on search history for this area to have been constructed between the 8 th of July 2009 and the 27 th of July 2009. The entire nest structure consists of relatively fresh brown sticks and while the nest tree is not considered the most stable tree in this area it appears that this nest may be a replacement nest for the deteriorating status of nest 1236. Since 2003 a total of seven nests have been located in this gully system. It is considered to be the most unusual territory within the District as there has been no disturbance in this area as a result of forest harvesting activity which is traditionally thought to be the prompt for such prolific nest development. The inspection of nests in Butler Creek gully system on the 27 th of July 2010 as detailed within this report found a highly variable report of the condition of nests in this area. This area has been proposed to both the FPA and DIPIWE as an area worth consideration for further study as it appears that something quite interesting is occurring with regard to patterns of use in this area. Nest was found to be in very good condition. The entire nest structure consists of relatively fresh brown sticks. Fresh bark and brown leaves were evident on the nest surface. The nest however was not lined at the time of inspection. The condition of this nest combined with the confirmed loss of nest 1237 and 1810 and the ongoing evidence of deterioration in the condition of nests 1236 and 1114 should mean that this nest while currently not displaying strong signs of expected use during the 2010 breeding season should be managed as indeterminate status and therefore active until such time as a further activity check can confirm the status of this nest. The required reserve for this newly located nest occurs entirely almost entirely within the reserve design previously in place for Nests 1810, 1237, 1114 and 1236. There will be a requirement however to extend the minimum reserve design slightly to capture the required minimum reserve. In addition a revision of this reserve is proposed to better capture shelter in this area and provide a better operational boundary for this area. There has been no recent activity within 500 meters or 1.0 kilometer line of sight of this newly located nest. Forest operations at SH087A are the most recent in this area with forest harvesting activity completed on the 24 th of June 2008. Forest activity however for this area was managed in accordance with breeding season restrictions for the previously known nests in this area. The FPP for this area specified a Section boundary for the management of known nests that is no different than that which would be required for this newly located nest. The District has yet to complete PI typing for this area and the associated confirmation of the location of the harvest boundary in this area. It is possible that the extension for the existing reserve in this area to capture this newly located nest may need to include a small part of SH087B that underwent partial harvesting in 2008. Very good condition nest. The entire nest structure consists of relatively fresh brown sticks. Fresh bark and brown leaves were evident on the nest surface. The nest however was not lined at the time of inspection. The condition of this nest combined with the confirmed loss of nest 1237 and 1810 and the ongoing evidence of deterioration in the condition of nests 1236 and 1114 should mean that this nest while currently not displaying strong signs of expected use during the 2010 breeding season should be managed as indeterminate status and therefore active until such time as a further activity check can confirm the status of this nest. No birds were observed during the inspection conducted on this day NEST NUMBER AND NAME Raptor Nest Activity Form SH087A Nest Complex Page 12 of 14
