Botanic Gardens Conservation International (BGCI)
Arboreta and Tree Conservation
Tree collections have long played an important role in science and research, and in the midst of the current plant extinction crisis, they have a vital role to play in species conservation. One in three tree species are threatened with extinction in the wild, so ensuring that they are conserved in ex situ living collections is critical to avoid species extinctions. While some tree species can be conserved in seedbanks, some of our most iconic groups, including oaks, maples and magnolias, cannot be stored as seed and thus can only be conserved as living plants. Several threatened species are currently represented by only few individuals in collections and creating resilient, genetically comprehensive collections is a crucial part of integrated species conservation programmes.

Presentation: What’s hitchhiking on you?
Who doesn’t love trees, and spending time outdoors, visiting woods and forests? Unfortunately, that can also include some unwelcome visitors. Non-native tree pests and diseases can have a significant impact on our landscape and the places we like to visit. However, there are a few simple steps that we can take to help limit their spread and the damage they can cause. Please join me to find out how these unwelcome visitors arrive here in the United Kingdom, what to look out for, and most importantly, what you can do to help.

Presentation: Tree Cover where you live, and why care
Do you know how many trees there are where you live? Do you know why it’s interesting, even important, to know? Did you know that you can assess tree cover yourself and that it’s free and easy to do so? In a recent study by Forest Research we learnt that a third of people would like more trees where they live and that they also felt that tree cover was unfairly shared across communities. This despite few actually knowing what their tree cover is. In this talk we’ll visit the benefits of trees in towns and cities, learn how to measure it and track change, and introduce you to the results of a long-running citizen science project that has sought to measure tree canopy cover for all the electoral wards of the UK.

Presentation: Living Legends
Some trees are unmistakeable giants, some may be as old as Stonehenge, while others are home to rare and mysterious creatures. These are more than just trees, these are living legends.
Trees have a talent for extreme longevity; our ancient trees have seen huge landscape change and major historical events. However, they’ve also been part of the everyday lives of generations of local people. This means that ancient trees are not only precious natural monuments, but cultural ones too.
In this talk we’ll discuss the value of ancient trees for people and nature. Please join me to find out why they’re tough yet also vulnerable, and how you can help to map, champion, and protect them.
Emma Gilmartin is a Conservation Adviser at the Woodland Trust. She specialises in the ecology and wildlife value of trees. Before joining the Woodland Trust in 2019, Emma gained her PhD at Cardiff University, researching wood decaying fungi in living beech trees with Professor Lynne Boddy. She has a background in recording fungi and plants across the UK, and loves to help others to identify and appreciate them. Emma helped to take ‘Unsung Heroes of the Planet’—the world’s first fungal opera—to the Green Man Festival in 2017, and she supports the Ancient Tree Forum and the British Mycological Society.
Presentation: Trees and their fungus partners
Trees use energy from sunlight to make carbohydrates during photosynthesis. This fuels not only their growth but ultimately the whole of the ecosystems that they dominate. Trees provide huge benefits to humans and the natural environment, such as providing habitat for many organisms, removing atmospheric pollutants, preventing soil erosion, cooling streets and cities, and having hugely advantageous psychological effects. However, they do not, indeed cannot, do this alone. Every tree on the planet is partnered by fungi, most obviously as mutualistic associations with their roots (called mycorrhizas), but also cryptically with endophytic (literally meaning within a plant) fungi in their leaves, stems, roots – in fact probably all tissues. They are also indirectly dependent on fungi, since fungi are the major rotters of dead plant tissues – especially when they contain lignin, and hence they are the major recyclers of nutrients, ultimately making nutrients available again for continued plant growth. This talk will explore these partnerships between fungi and trees.
Lynne Boddy is Professor of Fungal Ecology at Cardiff University UK. She has taught and researched into the ecology of fungi associated with trees and wood decomposition for 40 years. She is currently studying the fascinating communities of fungi and other organisms that rot the centres of old trees, the ash dieback fungus that is rampaging across the UK from Europe, the ways in which fungi fight each other and form communities, how they search the forest floor for food resources and respond to their finds, and how climate change is affecting fungi. She is a prolific author having co-authored “Fungal Decomposition of Wood” and “The Fungi”, her most recent (early 2021) being “Fungi and Trees: their Complex Relationships”, and the children’s book “Humongous Fungus”. She has edited six books, published over 300 scientific papers, and is chief editor of the journal Fungal Ecology. She was (2009–2010) president of the British Mycological Society. Lynne is an ardent communicator of the mysteries and importance of the amazing hidden Kingdom of Fungi to the general public including TV, radio, popular talks, videos, articles and exhibitions. She was awarded an MBE in the Queen’s Birthday Honours list in 2019 for Services to Mycology and Science Outreach.
Presentation: Trees for the Future
With the ever-increasing threats to our trees in the landscape from pests and diseases and climate change, we need to be more adventurous with our tree selection for future plantings if we are to have a treescape for the future. We need more diversity in our plantings and must avoid a monoculture planting. This will mean that we must integrate exotics with native species, and we must be planting nursery stock that will make shade trees when mature and not stick to planning pioneer species because they are easy to establish, albeit for a short time. The talk will explore potential species that we can plant in new planting schemes in the future.

Barrell Tree Consultancy
Presentation: Getting to the top of the tree; a tree consultant’s tale
If you have a passion for nature and the outdoors, and like getting your hands dirty, then working with trees can be a great career choice for a healthy and happy future when you are young and full of energy. It is satisfying work to grow new trees from seed in the nursery, plant them in the landscape, prune them as they mature, and finally fell them ready for the next generation to be planted. But what happens as you get older, and the work gets harder, and you can’t quite do as much as you could when you were younger?
One option is to use all that practical experience gained from those years of work to your advantage, and move on to advising others on how to manage their trees from a position of knowledge. Indeed, many of the UK’s top consultants started on the tools, and it is that experience that provides the tree-care insights needed to make well-informed management decisions.
In this short presentation, Jeremy will chart his career progress from a ground worker with a tree surgery company to become a highly accomplished consultant acting as an expert witness and speaking all over the world on the cutting-edge tree management developed in the UK.
If you are interested in a career in arboriculture, no matter what your background, this talk will provide insights into what it takes to get to the top and how important practical experience is as a building block towards becoming a successful tree consultant.
Jeremy Barrell is the Managing Director of Barrell Tree Consultancy www.barrelltreecare.co.uk, one of Britain’s leading planning and legal tree management practices. He is an author and accomplished expert witness, with a practical background focusing on delivering realistic solutions rather than academic nonsense.
BATS Research and Training Services
Presentation: Bats and trees
The UK is home to 17 species of bats, all of which are reliant on trees to varying degrees: Trees provide a source of food for bats, by supporting a vast array of insects and other small invertebrates; trees create linear features that allow bats to disperse through the landscape without predation; and trees offer homes for bats inside cavities, behind lifted bark or inside splits.
Bats are one group of animals that take advantage of the growth, damage and decay of trees. These processes provide abundant food and shelter for our bat species. Indeed, many of our rarest bat species prefer to live in trees over buildings, caves, etc.
But what type of trees do bats use and what can we do to protect their homes to ensure their survival? Come along and find out more about the relationships between bats and trees.
Jim is Director of BATS Research and Training Services, an organisation which strives for a world where bats are better understood, and their wild habitats cared for.
Jim is an ecologist and arboriculturist with dual specialisms of bats and veteran trees. He has been researching bats since 2005. He is an accomplished public speaker and training provider.
