Calley Heath Nature Reserve

On a walk round Calley Heath you'll soon discover it is not your typical nature reserve, but a diamond in the rough. On close inspection you will be delighted by the detail of tiny flowering plants in the short rabbit-grazed sandy grasslands, or the numbers of common butterflies feeding on flowering grass and willowherb heads in the old allotments.

Calley Heath is an area of grassy heath – a habitat rare in Yorkshire.


Tiny flowering plants can be seen in the grassland including bird’s-foot trefoil, dove’s-foot cranesbill and common stork’s-bill – all typical of these sandy soils. Hare’s-foot clover is worth looking out for, named for its fluffy-looking flower heads. Shepherd’s cress, recorded in only three other places in Yorkshire, also grows well here.

Parts of the site support rough grassland which is valuable for a huge number of insects. Over 370 fly species alone have been recorded here and the site is also important for beetles and bugs too. One fly species – Hilara gallica – was thought to be extinct in Britain until it was re-discovered here recently; the nature reserve is now its UK stronghold.

Top Tip:

Come mid-summer equipped with a hand lens or small magnifying glass to appreciate the tiny grassland flowers in full bloom. Crouching down you may also spot battalions of ants busy working or some of the beautiful mosses.

There are small areas of oak woodland in the drier parts of the site, with alders and willow fringing the ditches and in some of the wetter spots rushes and yellow flag iris grow.

At the time of the gold rush in America, when people travelled west to California to make their fortune, Calley Heath was granted to the poor of Barmby Moor by a local Trust – so the people here similarly travelled west to make their fortune – hence the area become known as Calley (or California) Heath.

When the Trust took on the nature reserve in 2003 parts of the site were agricultural set-aside. Since then work on the site has concentrated on removing invading scrub, bracken and bramble in order to restore the acidic grassland habitat. The two fields which had been previously farmed were re-seeded with a species mix to recreate the natural grasslands. A true success story, as restoration is really working on the site, with one of the seeded grasslands now species rich.
