According to the Woodland Trust, It seems this year’s late spring is having a knock on effect in delaying signs of autumn.
That’s according to initial observations from their Nature’s Calendar survey, which studies the timings of common seasonal events – Phenology.
Dr Kate Lewthwaite, Nature’s Calendar project manager explains. “What suggests that we could be in for a late autumn is if we look at the average dates of the first observed ripe berries over the past five years we can see that average peaks for this are around 4-6 August.”
“Considering that we have already passed that date and have very few records, it is apparent that autumn could be late this year, just how late we won’t know until the end of the season” she adds.
According to Victorian meteorologists, leaves were meant to start changing colour on 1st September but today’s leaves are not developing their autumnal hues until the end of the month. Also, oak leaves are not now falling until the end of October, a week later than 30 years ago, and on some milder parts of the UK people are reporting that their grass is growing all year round.
Add your own observations to the world’s longest written biological record, which has included nearly 2 million recorded seasonal changes since it began in the 1600’s!
The calendar is divided into two seasons, Spring (January to June) and Autumn (July to December), and there’s lots of changes to look out amongst the trees, flowers, birds, insects, amphibians and fungi.
You can record one event or many, just note the dates as you observe them and enter the dates onto your online recording form so that the live results maps are as up to the minute as possible. You’ll also receive regular emails keeping you up to date with the latest seasonal and climate change findings.
