Peatlands and peat bogs: precious environments that urgently need our protection
Peatlands are extraordinary environments, which now cover just 2-3% of our planet’s surface. Home to a fascinating range of native plants and wildlife, peatlands form unique ecosystems that support incredible flora and fauna. Many of the plants, insects, birds, and wildlife that have evolved in these boggy, acidic areas can’t survive anywhere else.
Sundews (Drosera) are carnivorous plants that thrive in peat bogs. There are at least three species of Drosera growing in the UK’s peat bogs, but many other Drosera species can found in Australia, New Zealand, South America, South Africa, and Alaska.
Peat is low in nutrients, but Drosera have evolved an effective method to sustain themselves, by trapping and feeding on flies and insects that they’ve captured with their specially adapted leaves.
How is peat formed?
These scarce ecosystems are very fragile; the formation of new peat depends on sufficient moisture being available, which combined with a slightly cooler temperature range, provides the conditions that enable sphagnum moss (which slowly forms peat) to grow, flourish, and reproduce. If optimum conditions occur, a new layer of peat, (measuring up to one millimetre thick) can be created over the course of a year.
Consequently, peat is not a resource that can be generated or replaced in a hurry; indeed, new peat production cannot be guaranteed. Very often the necessary conditions: the ideal temperatures and optimum light quality, necessary acidity and moisture levels, the required moss species being present (and putting on adequate growth) that combined together enable peat to be created, are not all in place simultaneously, for sufficient time; so as a consequence new peat is not always produced, every year.
Protection from flooding
Peatlands are precious habitats that help and protect us in many ways. In our changing climate, flooding is an increasing concern. Peatlands are naturally absorbent, they soak up and hold on to vast amounts of water, which helps to prevent flooding.
Water moves slowly through peat; peatlands curtail and soften the flow of water, to guard against flash floods. Sadly, many peatlands have now been excavated or intentionally drained; so the protection from flooding that these valuable areas once offered us is diminishing in parallel with our peat bogs.
Improving our water quality
Water that has travelled through a healthy peatland will have moved through an amazing natural filtration system that creates high quality water that’s essentially free from pollutants. A proportion of our drinking water in the UK has had the benefit of being filtered, purified, and improved, as it travels through peatlands.
Storing carbon to protect us against climate change
Peatlands are our largest terrestrial carbon store; they store more than twice as much carbon than all the world’s forests! Using their vital and impressive function as a carbon sink, peat bogs lock carbon safely away. Peatlands have absorbed billions of tonnes of carbon, but this carbon has not disappeared, it still exists and is held in safe keeping, contained within the peatland. When peat bogs are excavated, this benefit is lost and the carbon is released into the atmosphere.
It’s not only excavated peat bogs that are being weakened. Peatlands that have been drained to allow animals to graze, soon lose their ability to regenerate. As the water within the peatland reduces, the peat begins to erode and oxidise; once they start to degrade, peatlands begin to project their carbon stores back into the air.
Many Estates that run grouse shooting activities adopt a practice of burning moorlands to stimulate the heathers that grow in these areas to produced additional new growth, so as to provide more material to feed increasing numbers of grouse for people to come and shoot. This practice damages peatlands, killing the mosses that form peat, (along with the other plants, insects, and wildlife that make these areas their home) and unlocks the peatlands’ carbon stores.
New peat production is entirely dependent on sphagnum mosses. Sphagnum mosses’ new growth creates new peat; without these particular mosses, new peat cannot form and the peatland cannot prosper.
Many of the fragments of peatlands that remain have been severely damaged by peat extraction, which is heartbreaking. Yet, if these peat bogs are protected and restored they can recover. There is no quick fix, it will take a considerable time for the health of these important sites to improve, but with expert restoration it can happen. Professor Jane Barker and Simon Bland, who run Dalefoot Composts, are experts in peatland restoration; they take great pride in working to restore and repair peatlands that have been damaged by peat extraction or drainage.
Peat-free gardening…is it possible?
I am a peat-free gardener; I am an advocate for using peat-free compost. I successfully grow vegetables, fruit, herbs, and flowers, without using any peat in my garden.
Do plants need peat?
I think it’s important to say, that most plants will grow just as well in a peat-free compost as they would in a peat-based compost. You might be surprised to learn that many plants actually grow far better without the inclusion of peat in their growing media. Naturally there are exceptions, carnivorous plants that have evolved growing in peat bogs grow best in peat-based composts – but even then not just any old peat compost will do – you need to use a compost that’s specifically tailored for the type of carnivorous plants you’re growing.
Most plants thrive in peat-free composts. However some plants, like Rhododendrons need acid soils and ericaceous compost to flourish. In the past, ericaceous composts were always comprised of peat. Thankfully, we now have individuals and companies working to formulate high quality ericaceous composts that are made without the inclusion of peat.
Over the past four years, I’ve been growing Rhododendron ‘Dreamland’ plants (these plants were given to me by Millais Nurseries) in containers of Dalefoot Composts Ericaceous Wool Compost. My Rhododendrons are growing very happily; they don’t get watered very often, yet these plants flower beautifully, every year.
Why are peat-free composts more expensive?
Peat-based composts are cheap and easy for companies to produce, as the peat just needs to be excavated from the peatland and bagged up. In contrast, peat-free composts are expensive to produce. The ingredients needed to manufacture peat-free growing mediums need to be purchased and sourced from different areas; very often techniques, machines, and technologies are required to create these growing mediums, which usually need to be specially designed for this purpose. Naturally, areas of land need to be purchased, or hired, to create a space where peat-free compost can be generated, developed, and created, and once these components are all in place, it takes time for quality growing mediums to be devised, formulated, or invented.
To me, these costs are understandable; I believe it’s important to pay people fairly for their work and contributions. Purchasing a peat-free compost is an investment in our environment; peat-free composts are worth their weight in gold, as they help to protect our peatlands (and the plants and wildlife that live in these areas) ourselves, and our planet.
Can we make a difference?
Amongst the billions of people on this planet, it’s tempting to believe that any changes we make as individuals will have no real effect; it’s easy to feel that we cannot possibly make a difference to this beautiful planet ourselves. We might placate ourselves with the thought that one person who switches to a peat-free compost will make no difference whatsoever to the world. I disagree; I believe that we all make a difference.
If you consider how long it takes peat to form (a layer of peat measuring up to one millimeter thick, can be produced in a year with optimal growing conditions) and then remember the size of a compost bag, you’ll realise that we all make an impact; abstaining from purchasing peat-based composts will make a difference.
Let’s use our individual power for good; together we can change the world and the status quo. If we stop buying peat, then companies will have no need to continue extracting peat and they’ll find other ways to make money (hopefully by producing peat-free composts!). We must join forces to protect our peatlands. Peat is a precious resource, and our peatlands are a vital part of our environment. Peatlands need our protection now more than ever, just as we ourselves need the valuable security and protection that our peatlands provide us with.
Compost Trials to find top quality peat-free composts
I spend a huge proportion of my time and money running peat-free Compost Trials, to help my readers find the best quality composts to use in their gardens and allotments. I want to give you the confidence to purchase peat-free composts and help gardeners find top quality growing mediums, to enhance their plants and gardens, without harming the environment.
I understand that many gardeners have grown up using peat-based composts and the majority of gardeners are very familiar with this type of growing medium. Peat-free composts are not created equally; some are much better quality than others. But please don’t be daunted by the prospect of using peat-free composts; I want to show you that there are good quality peat-free composts on the market – I use my regular Compost Trials to demonstrate just how good peat-free composts can be.
Protect our peatlands and peat bogs
When we think of a precious environment, we might picture a coral reef or a rainforest. These areas are indeed precious and they must be preserved, but this is also true of our peatlands. The whole planet benefits from the protection that our peatlands give us; for too long this has been taken for granted.
I passionately believe that it is of vital importance that peat bogs are conserved, restored, and protected. I desperately want to encourage gardeners to give up peat and switch to using peat-free compost. It’s absurd for us to keep destroying peat bogs, whether it’s in the name of horticulture and gardening, or for any other industry. Together we need to care for and heal our planet and protect our peatlands.
We’re so fortunate to have areas of peatlands in the UK, Ireland, and Europe. I believe we should all be more aware and grateful for the protection, security, and blessings that these vital habitats offer us. We cannot allow our peatlands and peat bogs to continue to be damaged and destroyed, we should treasure and cherish these extraordinary environments. Peatlands play a fundamental role in enhancing and securing our life on Planet Earth; together we must stand up and protect these essential habitats, before it’s too late and our peatlands are lost forever.
If you would like to protect our peatlands and the rare, beautiful, and fascinating plants and wildlife that can only survive in these unique habitats, please sign this petition that calls on the Scottish Parliament to urge the Scottish Government to place a legal ban on the extraction of peat, peat imports, exports, and sales in order to protect peatlands both in Scotland and worldwide. Please share with your friends and family, and post a link to the petition on all your social media channels. Thank you.
Please don’t purchase peat-based composts; let me guide you to good quality 100% peat-free growing mediums.
