  1. Moss Terrariums and Bottle Gardens

    Comments Off on Moss Terrariums and Bottle Gardens

    This is one of a series of blogs written by Anthony Hall who beginning a three-month project to explore the secret life of historical moss specimens in our natural history collection in April 2021. This week he shows us how to create our very own bottle garden or ‘terrarium.’

    Terrariums are kind of indoor garden housed inside a glass case, sometimes completely sealed,  with a naturalistic arrangement of small plants, ferns and mosses. These miniature worlds can be beautiful and calming objects to look at and create. They are also scientifically interesting.

    I created this fishbowl bottle garden over 12 years ago using mosses and ferns I found growing in an aquarium; the spores must have drifted in on the wind. It is sealed with clingfilm and never needs watering.

    In recent times terrariums have become popular and they can be expensive. However, it is simple to create your own. Terrariums are self-contained ecosystems, which are powered by sunlight. The plants photosynthesise, releasing oxygen and water. The water is released into the air as gas which condenses on the sides of the tank. The water then trickles down into the soil. Bacteria in the soil break down the oxygen and creates carbon dioxide, which the plant can use. And so, the cycle continues.

    Here are some ideas for experiments with making your own self-sufficient world in a jam-jar with moss found in your garden or street.

    You can find out more about Anthony’s project from his website and discover moss trails around Oldham in our latest blog.

  2. Snipe Clough: Moss Trail 1

    Comments Off on Snipe Clough: Moss Trail 1

    Snipe Clough is a fantastic green site in the middle of Oldham with a range of open meadows, grasslands, woodland and boggy areas where moss can be found. Lookout for liverworts and moss growing on the damp branches under the tree cover and between the grasses in the boggy areas.

    • Photograph of liverwort on a stone.
    • Image of snipe clough and the pathway with trees in the background.

    There is a pond that is teeming with life, where you might be lucky enough to see large Dragonflies or Saw Flies, pond skaters and water boatmen under the surface. Also, look out for the mysterious concrete and brick vent structures; note the moss growing on these. See what insects you can find on these concrete structures. I found red spider mites, jumping spiders, and sunbathing Sawflies. The walk extends into densely wooded areas and a viewpoint overlooking Park Bridge. You will notice more mosses under the trees beside the trail and on soil banks.

    This trail is approximately 4 kilometres and take around 1 hour.

    River at Park Bridge.

    Starting at the car park at Park Bridge Heritage Centre, this walk takes you into the woods, and to a viewpoint overlooking the Medlock Valley, there are exciting mosses throughout the woods under the trees and on the soil banks.

    The trail then heads down into the valley again to follow the riverbank before heading along a road towards park bridge and up a hill. Eventually, you reach a moss-covered Stone bridge. Here you can follow the trail past a picnic spot beside rocky outcrops and ruins. Then at the broken bridge, follow a narrow trail alongside the Medlock take note of the moss is growing underneath the trees and on the rocks. You may even notice some succulent sphagnum mosses on the riverbank.

  4. Daisy Nook Country Park: Moss Trail 3

    Comments Off on Daisy Nook Country Park: Moss Trail 3

    Daisy Nook is a beautiful woodland following River Medlock, interested by the old Waterhouses Aqueduct and Hollinwood canal. It has a mixture of woodland paths and gravely wide tracks beside the canal, which are all great for moss. Look out for Liverworts on the muddy banks near the footpath and river. Also, check the fallen trees for different moss.

    The walk starts at a car park off the A627 walk into the woods and down to the riverside. Notice the damp stones by the river and many fallen trees with interesting mosses and liverworts. Following the moss trail, through the woods beside the River Medlock, you find more fallen trees for mushrooms and mosses, notice the steep banks beside the track, and mosses between the tree roots.

    When you get to the Waterhouses aqueduct, you can follow the brick embankment to Daisy nook country park visitor centre for a cafe stop. Double back to the aqueduct and follow the path up to the Hollinwood canal. Notice the mosses on the stonework and walls.

    The trail continues to a large pond, follow it round to the old Fairbottom Branch canal and all the way along the canal path to the A627 where you can get back to the car park.

    This moss trail is about 3.4 kilometres and will take approximately 1 hour to walk.

  5. ‘Biocrusts’ and ‘Blanket-bogs’

    Comments Off on ‘Biocrusts’ and ‘Blanket-bogs’

    Moss can bio-engineer hospitable environments for other plants and animals. In this post I write about my urban explorations of mossy carpets growing in urban space, and the ancient blanket-bogs and peatlands in the Peak District National Park.

    I have developed a permanently active ‘moss radar’. My favourite mosses to spot are still the most common species found in the urban environment. Much to my family’s irritation, I often stop to inspect random brick walls or tree trunks. Moss can survive in the most extreme environments. It can grow on surfaces devoid of soil baked dry in the sunlight and scoured by rainfall and wind. The moss somehow hangs on; it is resilient, and slowly persistent.

    As an ‘early coloniser’ moss can grow on bare soil or rock, helping to lock in moisture and bind the soil together. It can also help to form the growth substrate for other plants. A single spore slowly develops into a tuft and then a small clump, which can eventually conjoin with others to make a moss-carpet or ‘biocrust’ as is the more delightful scientific term. ‘Spreading earth moss’ (Physcomitrella patens) is known for its tolerance to drought and rapidly appearing on bare soil. It is widely studied by scientists, with the potential to be used as a tool to combat desertification[3]. Leptobryum pyriforme is a moss that grows on bare soil after forests fires. Some of the most fascinating urban moss sites I have visited are obscure abandoned car parks and buildings. I love how the moss envelops and subsumes and softens concrete blocks and jagged rock, or with enough time, almost any object that remains still for long enough.

    Next to a busy junction next to A627, there is an overgrown area; on closer inspection, this is a concrete footprint left from an old building enveloped by a thick carpet of Calliergonella cuspidata (Pointed spear-moss) and other feathery mosses. Other small shrubs and trees have grown in this, helping to maintain a moist environment under the shade.

    This is possibly ‘Cratoneuron filicinum’ a calcium loving moss I found in a car park, feeding on water seeping through the wall from the M50 motorway above. Underneath it has mineralised or calcified fronds. Over millions of years in the right conditions, this kind of biocrust on a larger scale can form into ‘travertine’ rock.

    Image Right: Oldham Panorama, by Squire Knott 1876. Whenever I visit Gallery Oldham, I like to spend some time looking at the Oldham panorama, a huge panoramic photograph, of which this is only a tiny detail.

    While many mosses are resilient and seem to thrive in the urban environment, some are very sensitive to pollution and are only found in more remote areas of the countryside. This panorama makes me think about what the air quality would have been like at the time. You can see the train carts arriving piled high with coal and the smoke-blowing chimneys rising into the skyline. In the distance, you can just make out the hills of the Peak District. During the industrial revolution, the hillsides of the Peaks District were stripped bare of plant life by acid rain. Sites such as ‘Bleaklow’ and ‘Blackhill’ (possibly named after the bare peat hillsides) were “downwind from some of the worst pollution the world has ever seen” [2]. Despite improvements in air quality these sites still need urgent need of protection. Pressures on peatlands from intensive land management, industrial pollution and wildfires have left them in a degraded and eroding state.

    I met up with Hydrologist Adam Johnston who took me on a walk from Edale up to the peatlands or ‘Blanket-bogs’ on the Kinder plateau. This remote site takes several hours to walk to. After a steep climb, the terrain change as we walked into the blanket bog was clearly defined by the blacked edges of exposed peat and a distinct sponginess underfoot. There is a wide diversity of plants and grasses and mosses and animals, some unique to this environment. There is something about the bleakness and quietness of this landscape that I find strangely calming. 

    • Adam Johnston standing in a deep Peat Gully
    Image Left: Adam Johnston standing in a deep Peat Gully. The erosion is clearly evident. Deep gullies and ‘peat-hags’ expose the black crumbling peat. Exploring one of the deeper gullies it was possible to see 3 metres depth of peat, right down to the gritstone rock underneath.

    These unique blanket bogs are home to specialist plants, such as Sphagnum moss which can hold 20 times its own weight in water. This kind of moss play a vital role in maintaining the wet conditions necessary to slowly create peat. 

    It is estimated that these blanket bogs have been growing for up to 8000 years. Without the active ‘biocrust’, the mosses and other plants, the peat dries out. It reacts with the air, releasing the carbon dioxide trapped in the peat over thousands of years. The exposed peat is less able to retain water and is washed away by rainwater or blown away by the wind. This also contributes to flooding in the lowlands. 

    Photograph of peatlands restoration work showing small dams ['Bunds'] in the gullies.

    The peatlands restoration work involves installing small dams [‘Bunds’] in the gullies. They help to retain water and create damp conditions for sphagnum moss and other wetland plants to grow back. In this image, you can clearly see how plant life is growing back behind the dam.

  6. Project launch: Moss Bothering

    Comments Off on Project launch: Moss Bothering

    We are pleased to announce that artist Antony Hall is beginning a three-month project to explore the secret life of historical moss specimens in our natural history collection.

    Mosses are bryophytes, which are a group of plants without roots. Antony will investigate our bryophyte collection and revisit the sites around Oldham where these specimens were originally collected, talking to experts and enthusiasts along the way.

    Antony will be recording his project on his own blog and via posts here on the Gallery Oldham blog.

    Part of Antony’s project will be taking beautiful photographs of these often over-looked plants. Antony will be recording his findings on his own blog and Instagram account. We will be sharing some of these each week on Gallery Oldham’s Instagram.
