Nature Now - March 2021

by Sarah Dobson Nature Now

Spring has now officially arrived, with Spring flora and fauna emerging much earlier than usual.

The days are getting longer as the Spring Equinox approaches on 20th March – when the Sun is directly over the Equator and day and night are of equal length.

Farmers will start to put their over-wintered livestock back outdoors, and the heartening sight of new-born spring lambs will once again be a joy to behold out in the fields.

Signs of spring life can can already be found if you look closely for them, including Snowdrops in flower for example. Yellow spring flowers are already emerging, from Daffodils to Dandelions as well as the buttercup-like Lesser Celandine lighting up woodland floors. Hedgerows and scrub are also starting to come back to life, to be covered by the attractive white flowers of Blackthorn which emerge on bare twigs prior to the leaves.

Some insects will shortly re-appear on the wing also, such as Bumblebee queens scouting for nesting sites as well as the charismatic large Bee Fly (a bee mimic), remarkable for its unfeasibly long proboscis!

Bird activity and song is noticeably ramping up, with male birds declaring their territories and pairing up with mates, especially during the increasingly noisy cacophony of the dawn chorus. Our resident birds’ numbers are significantly boosted by the progressive appearance of summer migrants from more southern climes, one of the earliest arrivals being the Chiff-Chaff whose distinctive two-tone song is heralded as a sound of spring.

The most wildlife activity this month is to be found in ponds however, where there have already been instances of Frogs spawning. As the weather warms up there will be lots more gelatinous clumps of Frog and (later) Toad spawn, together with the writhing bodies of multiple adults whose sole focus is to mate! The tiny tadpoles within the eggs hatch after about a month to form a wriggling mass within the water.

Lastly this month is most famous for its “Mad March” Hares, whose leaping and ‘boxing’ antics you may be lucky enough to witness upon the arable fields of the South Downs, as the females fend off the amorous attentions of enthusiastic males.
