BBC Radio Sheffield interview

Recently I was invited on BBC Radio Sheffield to talk about the reasons for getting out and about during the winter months. In this interview I describe the appearance of the earliest flowering tree species that are commonly found in woodland, plus some of the more distinctive tree buds that can be seen in mid-January.

We also discussed the value of slowing down to observe nature and of taking the time to learn plant names as a way of making connections with the natural world.

Listen from 2hrs 39 to 2hrs 49.

Sheffield: so close to nature

The folks over at Green City Heritage have been busy editing together this short film about Sheffield’s environmental heritage. In it you can meet some of the people who are advocating on behalf of trees throughout the city. This includes a small contribution from me in my Sheffield Woodland Connections role.

From spreading the appreciation of historic trees and ancient woodland to helping kids to plant new ones, there is a lot of love for trees in Sheffield.

Hedgehog mushrooms in Ecclesall Woods

This month has been a good one for mushroom collecting and these hedgehog fungi were foraged in Ecclesall Woods in mid-November, which is considered quite late in the year for this species. Hydnum repandum is one of the easiest fungi to identify as it has teeth or spines instead of gills.

They have an irregular convex cap with a slight wavy margin and appear ghostly pale against the browns and oranges of fallen leaves, which often half bury them due to their short stature. It always pays to look down at your feet when walking in the woods – in fact many of the ones I collected looked as if they had been kicked, whether purposefully or not.

Known as the wood hedgehog, wood urchin and sweet tooth, a mushroom that goes by this many names is usually either tasty or poisonous, otherwise there is little reason for it to be given much regard. Fortunately in this case it is due to its deliciousness, it is both sweet and nutty, and has a pleasant texture.

It is among the gourmet mushrooms that are sometimes seen in shops come late summer but never in great quantity. Only gather ones that are still creamy coloured, being careful to cut the stem low down to avoid damaging the mycelium that connects them to tree roots. Like all wild mushrooms, they should be cooked through before consumption.

They can be confused with the edible terracotta hedgehog, H. rufescens, which is aptly named for its warm brown colour, and the bitter tooth, Sarcodon scabrosus, which some regard as poisonous. In the latter case, the colouration is a much darker brownand tastes highly unpleasant.

As always, do not be tempted to use this visual description alone as a definitive ID for collecting fungi. The smell is important: it will have an earthy yet agreeable aroma. If in doubt, make a spore print – this will be white.

A triptych of chestnuts

Although it is quite late in the season to be foraging for sweet chestnuts (Castanea sativa), there were still a good number of edible nuts to be found during the first week of November. Ecclesall Woods is my favourite location for harvesting these delicious nuts. There are many large sweet chestnut trees in the woods, many of which were planted in the 1850s.

Sweet chestnuts are actually a Southern European species that were introduced into the woods as a fast growing alternative to native oak, with which it shares a high tannin content. This makes it a durable timber suitable for uses where a degree of water-resistance is required.

Luckily for us, many of these trees are now large specimens that produce an abundance of delicious nuts. Sadly some sweet chestnuts in Ecclesall Woods have been affected by Phytophthora aka ink disease on account of the dark spot-like stains that are seen on some trees, notably on beech. It is harder to see the early stages on the rough-barked chestnuts.

Should you go looking for chestnuts, remember to leave some for the wildlife. When gathering these I saw not one but two wood mice lurking in nearby brambles – it is not just the squirrels who like a nibble. Only take the big and firm nuts. If they are soft they are past their best; too small and they are a pain to shell.

Ecclesall Woods: A Virtual Exploration of the ‘Spring Wood’

A couple of weeks ago I teamed up with Green City Heritage to make this fab short film, in which I talk about the veteran trees of Ecclesall Woods. Come and meet these pieces of living history and learn how to recognise their special qualities.

Celebrating the Moss Valley Nature Reserve

A couple of weeks ago I had the privilege of spending two early mornings in the Sheffield and Rotherham Wildlife Trust’s Moss Valley Nature Reserve. In this protected landscape it is possible to see a range of wildflowers growing together in such density that it has to be seen to be believed. The site is a mixture of semi-natural and replanted ancient woodland and features plants such as red campion and yellow archangel that are far from common in this part of The Pennines.

These are the photographic highlights of the wildflowers you will find growing in Owler Car Wood in early May. For more botanical and tree photography visit: fran-halsall.co.uk

English bluebell (Hyacinthoides non-scripta) are a useful indicator species, as where they exist in high concentrations it is reasonable to assume that the woodland is ancient (dating back at least 400 years).
Lamium galeobdolon
Yellow archangel (Lamium galeobdolon) is another of the ancient woodland indicators that grow here. While the leaves are similar to stinging nettles, the yellow hooded flowers are quite different.
Red campion (Silene dioica) grows in woodland glades, old hedgerows and roadside verges. Flowering between May and October, it is a food plant for bees, butterflies, hoverflies and more.
Wild garlic (Allium ursinum) grows in the damp soils down by The Moss, the brook from which the valley takes its name. Wild garlic is just one of the many ancient woodland indicator species growing here.

Woodland wanders with Sheffield Woodland Connections – bluebells in Ecclesall Woods 8th May 2020

A short video among the English bluebells (Hyacinthoides non-scripta) tracing the winding paths in Ecclesall Woods, Sheffield. Enjoy the sights and sounds of South Yorkshire’s largest ancient woodland in all its springtime splendour. With around 50% of the world’s population, Britain is the only place where you can see such large colonies of bluebells and the dazzling display only lasts for a month at most.

Bluebells are a key ancient woodland indicator species and where extensive carpets of them are seen it is safe to assume that you are in woodland dating back at least 400 years. While the bluebells themselves are not this old the bulbs lay dormant in the soil, surviving for decades while they wait for enough light to flower and creep incrementally outwards.

Newfield Spring Wood: ancient woodland indicator species

On a recent visit to Newfield Spring Wood, a woodland close to my home in the southwest of Sheffield, I spotted a classic ancient woodland indicator species: yellow archangel (Lamium galeobdolon). This foliage of this plant superficially resembles the familiar stinging nettle (Urtica dioica), however it can be easily distinguished when in flower. Stinging nettle has lots of tiny ball-like flowers hanging down in chains, whereas yellow archangel has whorls of bright yellow hooded flowers. The adventurous could also tell them apart by testing the leaves – if it hurts it is a stinging nettle!

On this occasion I saw yellow archangel growing alongside white dead-nettle (Lamium album) – also a non-stinger, which has similar flowers (but in white) and broader leaves. Included below is a photo of them growing together to make identification easier.

Although yellow archangel should be a locally common species associated with the ancient woodlands and hedgerows of Sheffield, what is actually frequently found is Lamium galeobdolon ‘Variegatum’ which, as the name suggests, has a variegated leaf. This is a cultivated species that often escapes from gardens into woodlands.
