The results are in for BSBI’s tenth New Year Plant Hunt, when plant-lovers cross Britain and Eire head out to see what’s flowering of their native patch. 1,811 individuals took half this 12 months – greater than ever earlier than – however restrictions round Covid-19 had stunning impacts on the wild flowers they noticed in bloom.

They hunted for as much as three hours over the New Year interval and recorded extra species in bloom than ever earlier than. Right here’s what they discovered:

•710 completely different plant species had been recorded in bloom throughout Britain and Eire in comparison with 615 final 12 months and 627 in 2019.

•A complete of 21,419 data had been submitted: nearly 50% greater than final 12 months.

•1,195 lists had been submitted, in comparison with 798 in 2020 and 712 in 2019.

•1,811 individuals participated, both individually or as a part of small household teams and assist bubbles – our ordinary giant group Hunts had been all cancelled because of Covid-19.

•Plant hunters joined in from Orkney to Guernsey, from Anglesey to Norfolk, and from Donegal to south west Cork.

As anticipated, the milder south and west of Britain and Eire had the very best numbers of species in flower – 86 on Jersey. That is lower than the 2020 whole of 115 species in Swanage and nearly half the 2016 prime whole of 162 species recorded in Berkshire.

Ellen Goddard of BSBI’s Occasions & Communications Committee has analysed this 12 months’s results and in contrast them with these from earlier years. She stated “2021 has been a report-breaking 12 months, with extra species recorded in bloom and extra lists submitted than ever earlier than, however we’re nonetheless seeing the identical cut up of native vs non-native crops. We’ve additionally seen a change in the way in which individuals took half within the Hunt this 12 months: with organised group hunts cancelled because of Covid-19 restrictions, individuals have been going out on their very own or in small household teams and assist bubbles. This has led to a small enhance (c5%) within the numberof members however a marked enhance (45-50%) in whole lists and data submitted. That is prone to have performed a big half within the increased variety of species recorded this 12 months, however there was additionally the next temperature anomaly than we noticed in 2020. So, the Covid-19 restrictions might have influenced how individuals took half within the Hunt however the hotter climate within the interval main as much as the Hunt might even have influenced the whole variety of species and the variety of data we obtained.

The principle findings from this 12 months’s knowledge had been:

•53% of the flowering species reported had been of crops which usually flower after midsummer and had managed to hold on flowering. These embody ‘Autumn Stragglers’ equivalent to Yarrow, Ragwort and Hogweed. This proportion is similar to earlier years.

•Solely 24% had been ‘Springtime Specialists’ like Primrose and Lesser Celandine, so there isn’t any indication of an early spring. This proportion is much like earlier years.

•23% of the data submitted had been of species we would moderately count on to flower at New Year, or species which we can not simply be categorised as both ‘early’ or ‘late’. These embody typical ‘All Year Rounders’ equivalent to Shepherd’s-purse in addition to ‘Winter Specialists’ equivalent to Winter Heliotrope.

•The highest 4 most regularly seen species had been Daisy, Groundsel, Dandelion and Annual Meadow-grass – this was similar to final 12 months’s record and all (native) crops that we might count on to be flowering right now of 12 months.

•Clean Sow-thistle moved into fifth place on the High Twenty record of most frequent crops, changing Widespread Chickweed which moved to quantity 14 on the record.

•Bramble and Nipplewort entered the High Twenty changing Winter Heliotrope and Ivy.

•36% of species recorded had been non-natives (aliens). This consists of crops from hotter climates which have escaped from gardens or cultivation, turn out to be naturalised within the wild and had been capable of prolong their flowering into the winter months. As in earlier years, city areas tended to have extra non-native species in flower than rural areas, as there are extra sheltered and disturbed locations with heat microclimates the place alien crops can thrive.

Kevin Walker, BSBI Head of Science stated “As Ellen’s evaluation of the New Year Plant Hunt reveals, our crops are responding to altering climate patterns, with extra flowers being recorded through the previous decade as we expertise autumns and winters with hotter temperatures and fewer frosts. We can not, nevertheless, show conclusively that extra species are flowering these days in mid-winter in comparison with in previous years. We will’t say for certain but what impacts these adjustments in flowering instances can have on related wildlife – however we will see that climate patterns are altering and our crops, each native and non-native, are responding.

Every day highlights of individuals’s Hunts throughout Britain and Eire had been posted on the BSBI Information & Views weblog and shared through social media.
