Twisted Wrack

Scientific Name: 
Fucus spiralis

Twisted or 'Spiral' Wrack is a common 'wrack' seaweed that grows just below the high water mark on rocky shores. Living on the upper shore, it is very tolerant of desiccation and can survive out of the water for long periods, although not as long as Channelled Wrack. It can live for up to four years.

How to identify: 
Twisted Wrack is a pale olive-brown 'wrack' seaweed, recognised by the spirally twisting fronds with an obvious rib down the middle, and the yellowish, paired swollen tips which are the reproductive structures.
Where to find it: 
Common on rocky shores all around our coasts.
How people can help: 

Seaweeds provide a vital link in the food chain for many of our rarer species. Our seas and coastline are in need of protection if we are to keep our marine wildlife healthy. The Wildlife Trusts are working with fishermen, researchers, politicians and local people towards a vision of 'Living Seas', where marine wildlife thrives. This work has recently had a massive boost with the passing of the Marine Bill, promising sustainable development of the UK's marine environment. Do your bit for our Living Seas by supporting your local Wildlife Trust.

Statistics: 
Length: up to 40cm
Conservation status: 
Common.
Did you know?: 
Twisted Wrack spends up to 90% of its time out of the water and can survive water loss of up to 80% - it curls up as it dries to conserve moisture. However, it is common for Twisted Wrack to adapt to stress over a number of weeks, essentially acclimatising to drought. So it is often the case that specimens closer to the sea, and which are submerged more often, are less able to tolerate drought stress than those higher up the shore.

Channelled Wrack

Scientific Name: 
Pelvetia canaliculata

A very common seaweed, Channelled Wrack grows around the high water mark on sheltered, rocky shores. Living on the upper shore, it is very tolerant of desiccation and can survive for up to eight days out of the water. In fact, if it is fully submerged for too long, it may die. Channelled Wrack can live for up to four years.

How to identify: 
A smallish brown 'wrack' seaweed, Channelled Wrack can be recognised by the obvious 'channels' that its frond form - produced by their sides being rolled in. Lighter-coloured, bumpy, v-shaped swellings at the ends of the fronds are its reproductive structures.
Where to find it: 
Common on rocky shores all around our coasts.
How people can help:

Statistics: 
Length: 5-15cm
Conservation status: 
Common.
Did you know?: 
Channelled Wrack is a hermaphrodite, so it has both male and female structures. The gametes are released in August and September from the swollen tips of the fronds (receptacles) and are fertilised externally in the water. They settle as tiny sporelings, developing through the winter.

Sugar Kelp

Scientific Name: 
Saccharina latissima

Sugar Kelp (or 'Sugar Wrack') is a common 'kelp' seaweed which grows around the low water mark, attached to rocky shores up to 30 metres deep. It favours sheltered conditions. Sugar Kelp can live for up to four years and grows particularly quickly during early spring. Living up to its common name, Sugar Kelp is sweeter than other kelps, so is used in cooking from Scotland to Japan.

How to identify: 
Sugar Kelp is a large 'kelp' seaweed, dark browny-green, with a single broad frond that has a distinctive crinkly and wavy edge.
Where to find it: 
Common on rocky shores all around our coasts.

Oarweed

Scientific Name: 
Laminaria digitata

Oarweed is a common 'kelp' seaweed which grows in dense beds, attached to rocky shores by its tough, root-like holdfasts. It can grow at depths of up to 20 metres in clear water, and flourishes in strong currents. The floating fronds may be exposed at low tide. Oarweed is a perennial which can live for up to six years; although growth occurs throughout the year, it is fastest in spring.

How to identify: 
Oarweed is a typical 'kelp' seaweed, dark browny-green, with long fronds split into long 'fingers' or 'ribbons'.
Where to find it: 
Common on rocky shores all around our coasts.
How people can help:

Sea Lettuce

Scientific Name: 
Ulva lactuca

Sea Lettuce is a common seaweed of many different beach habitats; it can often be found attached to rocks in sheltered shores, but also thrives in rock pools even if it has become detached from its substrate. Its holdfast portions (the area that sticks to the substrate) are perennial and grow new fronds each spring.

How to identify: 
Sea Lettuce lives up to its name: it looks like green, floppy lettuce leaves which are often tatty in appearance but are quite tough.
Where to find it: 
All around our coasts.

Gutweed

Scientific Name: 
Ulva intestinalis

Gutweed is a common seaweed of rock pools, saltmarshes and seawater ditches, and is particularly abundant in brackish water. It is often seen with bubbles of air trapped inside its long fronds which have the look of intestines, hence its name. It is sometimes attached to substrate, but may become detached, forming floating, growing masses. It is a summer annual so will decay and form masses of bleached fronds towards the end of the season.

How to identify: 
Gutweed is a mass of bright green, inflated tubes, often with pinched-in 'waists' along its length. Fronds are typically unbranched.
Where to find it: 
All around our coasts.
How people can help:

Statistics: 
Length: up to 75cm Frond width: 6-18mm
Conservation status: 
Common.
Did you know?: 
This fast-growing species can reproduce quickly. It goes through a number of stages in its lifecycle including the gametophyte stage when it produces gametes (mobile sex cells) that fuse together to form the sporophyte stage. This stage releases spores that develop into the gametophyte stage and the whole process starts again. This seaweed can turn water green with the release of masses of gametes and spores.

Broad-leaved Helleborine

Scientific Name: 
Epipactis helleborine

The Broad-leaved Helleborine is a tall, dark orchid with leaves that spiral around the stem and purple-tinged, drooping flowers. It flowers from July to September and can be seen mainly in woodlands and scrub, but oddly prefers waste grounds in and around the city of Glasgow.

How to identify: 
The Broad-leaved Helleborine has broad, oval leaves with strong veins at its base, and smaller leaves that wind their way up the stem. A single flower spike has loose clusters of drooping flowers that are greenish with a purple tinge.
Where to find it: 
Found throughout the UK, but populations mostly concentrated in England and Northern Ireland.
How people can help: 

The Wildlife Trusts manage many nature reserves for the benefit of all kinds of wildlife, including many different species of plants. But these precious sites are under threat from development, intensive agricultural practices and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.

Statistics: 
Height: up to 75cm
Conservation status: 
Common.
Did you know?: 
Some species of wasp and bee that are attracted to Broad-leaved Helleborines have been noted as becoming 'intoxicated' after visiting these orchids for nectar - it appears that the flowers can contain a kind of alcohol as a result of a fungus; the bees like it so much, they come back for more, ensuring the flower is pollinated.

Marsh Helleborine

Scientific Name: 
Epipactis palustris

A stunning orchid of wetland areas, the Marsh Helleborine can be found in fens, damp grassland, marshes and dune slacks, especially with chalky soils. Its rather loose flower spike carries up to 20 white and pink flowers during July and August; in some areas, forests of hundreds of plants can colour the green marsh vegetation. But despite its profusion in certain areas, the Marsh Helleborine is declining due to habitat loss.

How to identify: 
The Marsh Helleborine has broad, oval leaves at the base of the stem and narrower leaves higher up the stem. The flower spike consists of a loose cluster of white flowers with a white, frilly lip and reddish sepals that look like wings. They hang on reddish stalks attached to a reddish stem.
Where to find it: 
Grows mainly in England; locally common in the south.
How people can help: 

Human activity, including the drainage of land for agriculture and development, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected and managed for the benefit of the plants and animals they hold, including the Marsh Helleborine. We have a vision of a 'Living Landscape': a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust.

Black Bryony

Scientific Name: 
Tamus communis

Black Bryony is a climbing hedgerow and woodland edge plant that flowers between May and August and produces red and shiny berries that can be seen, covered in frost, in winter. Our only native member of the yam family, Black Bryony is actually highly poisonous. Despite its name and superficial resemblance, it is not a relative of White Bryony.

How to identify: 
Black Bryony is a twisting climber but lacks the tendrils of White Bryony. Its leaves are heart-shaped, glossy and their veins form a net pattern. Black Bryony displays yellow-green, six-petalled flowers and red berries.
Where to find it: 
Predominantly found in England and Wales.
How people can help: 

Our hedgerows support all kinds of wildlife, providing vital food and shelter. But these habitats are disappearing with the intensification of agriculture. The Wildlife Trusts are working closely with farmers, landowners and developers to promote wildlife-friendly practices, such as planting hedges and leaving field margins. We have a vision of a 'Living Landscape': a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust.

Statistics: 
Height: up to 3m
Conservation status: 
Common.
Did you know?: 
Black Bryony grows from a tuber (a modified root that stores nutrients) which develops about 10-20cm below the soil. This tuber can grow very large, reaching 60cm width and is, like the rest of the plant, highly poisonous.

Yellow Iris

Scientific Name: 
Iris pseudacorus

The water-loving Yellow Iris can be found along the margins of waterways and ponds, and in wet woodlands, fens and saltmarshes. Often mingled among other reedbed plants, its large, bright yellow flowers appear between May and August and are thought to be the inspiration for the fleur-de-lis symbol which is used in heraldry and also by the scouts.

How to identify: 
Yellow Iris has tall reed stems that are sometimes branched. Its long, narrow leaves are grey-green and sword-like, and may droop at the ends. Its large, yellow flower petals fold back on themselves and hang down around the outer edges of the flower.
Where to find it: 
Widespread.
How people can help: 

Human activity, including the drainage of land for agriculture and development, has resulted in the disappearance of many of the UK's wetlands. The Wildlife Trusts are working closely with planners, developers and farmers to ensure our wetlands are protected. You can help too: add native plants and flowers, such as Yellow Iris, to a wildlife-friendly pond and its margins, and provide shelter for amphibians and nectar for insects. In partnership with the RHS, The Wildlife Trusts' Wild About Gardens initiative can help you plan your wildlife garden.

Statistics: 
Height: 40-100cm
Conservation status: 
Common.
Did you know?: 
Yellow Iris can be invasive and may easily take over a small pond; it has even become a problem in the wild in some areas where it has escaped and spread from cultivated varieties. To avoid it taking control, try planting it in a basket around the margins of your wildlife pond to keep it contained.
