Red squirrels have adapted to live alongside pine martens as both species evolved in Europe, and have a greater awareness of the threat posed by the predators.

In Northern Ireland, small, remnant populations were all that remained, but today, the species is recovering, and this comeback may help ensure the long-term future of the red squirrel in Ireland.Joshua Twining, who will be presenting the research at the conference, commented“the red squirrels ‘positive response’ is likely due to grey squirrel disappearance rather than red squirrels and pine martens working together.”Pine martens eat both red and grey squirrels, though the key difference is that red squirrels have evolved alongside pine martens over millennia, making them able to coexist.Twining said, “The ability of the pine marten to control the grey squirrel and help red squirrel recovery in Ireland and Britain is limited by three things; its ongoing recovery, the lack of forest cover on the island and the presence of urban areas.” Twining and co-authors suggest that grey squirrels will persist in the latter as results show pine marten are forest specialists and avoid urban areas.Although the red squirrel population is increasing in Northern Ireland, the researchers warn that“unless the issue of control within populated areas is addressed, we risk creating a situation where marten-savvy grey squirrels could recolonise the wider landscape in the future.”“does not occupy urban areas anywhere within its European range, it is not likely to be the sole solution to the invasive grey squirrel”If pine marten are to extend their positive impact on red squirrels, issues impeding pine marten recovery need to be addressed. Native red squirrels set to benefit as research shows pine martens predominantly target non-native grey squirrels.European pine martens predate on non-native grey squirrels significantly more than native red squirrels, according to new research by Queen’s University Belfast.Both squirrel species feature on the mustelid’s menu, but grey squirrels are preyed upon exclusively during the squirrel’s spring and summer breeding season.
TV SHOW We spoke to Emma about her past and current research on the relationship and the history of pine … As part of the research, Joshua Twining surveyed 24 forestry sites across Northern Ireland known to have a relatively high abundance of pine martens and the presence of either red or grey squirrels. TV SHOW Red squirrels, however, have evolved to live alongside pine martens in their shared European homeland and appear to have a greater awareness of the threat they pose.It is also suspected that grey squirrels are preferred by pine martens as they are larger (and therefore a richer energy source) and found in higher numbers.“Our results are interesting as they help explain the mechanism underpinning how pine martens are able to regulate invasive grey squirrel populations, and give a much-needed boost for another one of its prey species, our native red squirrels,” adds Twining.Nida Al-Fulaij, grants manager at PTES, says: “It’s important that we understand exactly how pine martens are faring, which includes their predation habits. Pine martens show a preference for non-native grey squirrels over native red squirrelsTry 3 issues of BBC Countryfile Magazine for just £5! "Now, after centuries of widespread persecution and habitat loss, most recent estimates suggest there are only around 3,000 in Ireland and 9,000 in Great Britain, with only approximately 100 thought to be living in England. The resurgent population of pine martens that is returning to Powys may be helping reduce the area's grey squirrel population.
