  • A year in the life of a tree

    By Judith Garforth, 12/12/2019

    The Woodland Trust has decided to follow and document a year in the life of a single tree and we'd like you to do the same. We're monitoring the Grantham Oak, a beautiful tree more than 400 years old, that many of us pass on our way to work. The tree is looking very wintry now having just lost its leaves. We're recording the dates of all the seasonal changes that happen to this tree for the Nature's Calendar project. Look out for photos throughout the year which we'll share in this blog, and on our social media channels. Why don't you monitor your favourite tree this year too?

  • Are you watching out for Autumn?

    By Lorienne Whittle, 26/09/2019

    Is nature in time with our autumn calendars? Whilst the meteorological and astronomical definitions of autumn have now passed, we take a look at your records to see how autumn is revealing itself in trees and shrubs across the country.


    Autumn is known as the forgotten season in phenology, with fewer records of key events compared to spring. So we know less about how the timing of events in autumn are changing. To fill in these knowledge gaps we’re especially keen get your autumn records, so take a look at  Nature’s Calendar for some seasonal inspiration.
