“Definition of Favourable Conservation Status for the Peregrine Falcon Falco peregrinus”
Author: Allan Drewitt (Nov 2020)
This is part of a wider Natural England project to define the Favourable Conservations Status (FCS) of various habitats and species in England at which they might be considered to be “thriving”. The project aims to set aspirational levels for species’ populations and habitat conditions that will inform and guide decision makers to help achieve and sustain favourable status. These analyses are based on ecological evidence and the expertise of specialist groups.
The Northern England Raptor Forum welcomes the report defining the would-be Favourable Conservation Status for the Peregrine Falcon.
Many of our members have conducted long standing field studies into the fortunes of Peregrines in their area and contributed significant bodies of data to the key published papers that are cited in the Natural England report [Amar A. et al (2012), Melling T. et al (2018), Wilson M.W. et al (2018)].
Whilst the breeding populations of Peregrines in many areas of England have shown a general pattern of increases in recent decades the report makes clear this same trend is not evident in the northern uplands. Here marked losses in the range and population have been experienced and continue to this day. In particular, breeding productivity at sites on or near driven grouse moor estates is half of that found on non-grouse moor habitats. There are now significant gaps across the northern uplands where Peregrines previously bred and where overall numbers are lower compared to the 1990s and 2000s, for example in the Dark Peak, Bowland Forest and the North Pennine SPA.
The report concludes that current productivity in these areas is insufficient to allow the population to grow. Restoration of the Peregrines’ natural range in the northern uplands would result in the presence of 90 pairs (compared with probably less than 20 pairs presently). Crucially, the report judges that neither the habitat nor food abundance in the northern uplands are limiting to population growth.
The principal reasons that upland Peregrines are faring so badly are given as illegal killing and nest site disturbance and the report makes clear that for a FCS to be achieved in England a significant growth in the northern upland population is now required and these illicit practices must cease.
Natural England have thus defined the underlying problem, which in itself is hardly news to many raptor fieldworkers. However the FCS report does set an aspirational target for the future which is to be welcomed. So far so good, the explicit acknowledgement that illegal activities are limiting upland populations is a positive step forward. The FCS has achieved its initial objective but the purpose of the report is inherently limited to just this so action plans with timelines are now needed urgently to deliver the stated goals. We now hope and trust Natural England will lead the way** with a renewed determination.
