In this Wednesday episode of Talking Trees, we explore how thoughtful tree species selection is essential for building resilient green infrastructure in cities facing climate change, soil limitations, and urban stressors. We discuss: Why tree selection should be based on site-specific conditions, including soil compaction, heat exposure, and rooting spaceTools and frameworks for choosing species, including guides that rate trees by drought tolerance, flood resilience, and ecosystem service po...
In this Tuesday episode of Talking Trees, we dive into the world of friction hitches, essential tools for climbers that provide control, safety, and flexibility during ascent and descent in tree work. We discuss: How friction hitches function by gripping the rope under tension while allowing easy adjustment when unloadedPopular hitches like the Prusik, Blake's Hitch, Valdotain Tresse (VT), JRB, and Longhorn, and how each performs under different climbing systems (Ddrt and SRT)How to match hit...
In this Monday episode of Talking Trees, we explore how urban trees respond to rising temperatures and what determines their heat resistance in the face of climate change and the urban heat island effect. We discuss: The physiological and biochemical effects of heat on trees, including impacts on photosynthesis, respiration, and water regulationMethods to assess heat tolerance, from leaf-level tests to remote sensing technologiesWhy urban trees are particularly vulnerable due to limited rooti...
This is your weekly summary of the Talking Trees podcast! 🌱 Monday 156 - Transpiration, Evaporation and Interception We explored three key water-related processes in trees—transpiration, evaporation, and interception—and how they influence tree health, microclimate regulation, and the hydrological cycle. 🧗 Tuesday 157 - Personal Fall Protection Systems We discussed climbing safety systems, focusing on moving and stationary rope techniques, backup anchor systems, and the importance of proper...
In this Saturday episode of Talking Trees, we take a closer look at the Cerambyx cerdo, also known as the great capricorn beetle—a striking and ecologically significant member of the longhorn beetle family. We discuss: Its scientific classification and broad geographic range across Europe, Asia, and North Africa, with historic extinction noted in the UKThe beetle’s distinctive appearance, including body size, dark coloration, and the notable difference in antenna length between males and fema...
In this Friday episode of Talking Trees, we pay tribute to one of the most influential figures in modern arboriculture—Prof. Dr. Dirk Dujesiefken. His career has shaped the way we understand, teach, and care for trees in urban environments across Europe. We discuss: His early fascination with nature protection and the urban role of trees, which led him from studying wood to researching living trees and tree care systemsThe founding of the Institute for Tree Care and its three central pillars:...
In this Thursday episode of Talking Trees, we delve into the use of acoustic tomography—specifically the PiCUS Sonic Tomograph and TreeTronic systems—for diagnosing hidden internal decay in trees. We discuss: How sound waves and electrical resistance are used to map internal wood structure without damaging the treeThe key steps in setting up, calibrating, and interpreting tomograms, including common challenges like the “cogwheel effect”Insights into the biology of wood-decay fungi and how tom...
In this Wednesday episode of Talking Trees, we explore the principles and practices of dynamic tree cabling, a system designed to enhance tree stability while allowing natural movement and growth. We discuss: The difference between dynamic and static cabling systems, and when dynamic solutions are most appropriateKey installation principles such as placement height, tension calibration, and selection of appropriate materialsHow dynamic systems absorb energy and reduce mechanical stress, helpi...
In this Tuesday episode of Talking Trees, we dive into the essentials of Personal Fall Protection Systems (PFPS) used in modern arboricultural climbing and aerial rescue operations. We discuss: The two primary climbing techniques: Moving Rope Technique (MRT), where the rope moves over an anchor point, and Stationary Rope Technique (SRT), with a fixed rope setupThe structure of a fall protection system, which includes a main line and a backup system, both critical to minimize the risk of a fal...
In this Monday episode of Talking Trees, we explore three essential water-related processes—transpiration, evaporation, and interception—that shape how trees interact with their environment and regulate the water cycle. We discuss: Transpiration, the movement of water from roots through the plant and its release as vapor from leaf surfaces, driven by sunlight, humidity, and stomatal activityEvaporation, the transformation of water from liquid to vapor at exposed surfaces such as soil, bark, o...

From soil macropores to seaweed-based biostimulants, this episode provided practical insights for improving tree establishment and root resilience. 🧷 Tuesday 150 - Tree Climbing Spikes T...
In this Saturday episode of Talking Trees, we turn our attention to the human dimension of biodiversity protection, exploring how public attitudes shape conservation outcomes and the role arboriculture plays in supporting a healthy social-ecological system. We discuss: A national study from Spain revealing that the general population holds a strong pro-conservation stance toward protecting threatened floraSurvey insights into public willingness to support government spending, and even limit d...
In this Friday episode of Talking Trees, we explore the soil microbiome as a critical but often overlooked driver of tree health, biodiversity, and ecosystem resilience. Far beyond just a substrate for roots, soil is a living, dynamic system influencing the entire tree environment. We discuss: How soil microbial communities support nutrient cycling, disease resistance, and plant growth through complex interactionsThe concept of soil health as a foundational element of the One Health framework...
In this Thursday episode of Talking Trees, we focus on the global threat posed by Phytophthora species, aggressive plant pathogens that have devastated forests, gardens, and natural landscapes worldwide.
