The conversation discusses the importance of valuing trees and the challenges in calculating their value. It emphasizes the need to consider the eco-benefits, property value, replacement value, wildlife value, and ecosystem value of trees. The conversation also touches on the role of municipalities in decision-making and the irreplaceable nature of trees. The interviewee highlights the importance of proper tree assessment and the need to consider the age structure, species structure, and maintenance history of trees. The conversation also explores the concept of canopy cover and the challenges of tree planting and aftercare. The interviewee shares insights into the arboricultural scene in the Czech Republic, including the strict legislation around tree felling and the growing number of arborists, including women, in the industry. The interview concludes with a discussion on the ambition of the European Arboricultural Council to spread the standards and promote tree care at a higher level.
"EAC was created to increase the level of Arboriculture in Europe and the first products were certification programs, European tree worker and European tree technician.""Certification is necessary to choose qualified companies or individuals for tree care work, especially when larger financial amounts are invested.""The certification for veteran tree specialist is a jewel among arboriculture qualifications, focusing on the care of irreplaceable old trees and the ecosystems connected to them.""In our cities, mostly in the cities in southern part of Europe without trees we are not going to survive really in the cities.""Just imagine that if we just consider the tree being represented only by let's say some replacement value but the replacement itself is going to happen within 60 years.""The first questions should not be about the value, about the money because that's only the last resort how to express the value of the trees."

Built and natural environments are often referred to independently, but in reality, comprise two defined parts of one environment. Within the environment, trees and buildings exist, though not always in equal relationships. Where development is proposed, taking precedence over trees, an imbalance between natural and built environments may occur. This could be the result of tree- building conflict often resulting in tree removal. Where architects are creators of the built environment, there is a professional responsibility to consider the wider environmental context impacted by development and also the contributing benefit that trees offer to the environment.
In this episode, Sharon interviews Dr. Gary Wynn, an innovative architect and arboriculturalist. Gary shares his journey of becoming an arboriculturalist and the lack of tree knowledge among architects. He discusses his research on the relationship between trees and buildings and the need for architects to have arboricultural knowledge. Gary also talks about his architectural philosophy, inspired by Frank Lloyd Wright, and the importance of seeing the world as a connected system. He shares a case study of a building he designed near trees and the engineering considerations involved. The conversation ends with a discussion on the tension between the benefits of trees and the challenges they pose in urban areas. Dr. Gary Winn discusses the successful relationship between trees and buildings, highlighting the benefits, challenges, and innovative design solutions. He emphasizes the need for architects and arboriculturists to collaborate and integrate tree considerations into the design process. Dr. Winn shares his research findings, which show that architects often lack knowledge about trees and perceive them as obstacles. However, through workshops and practical exercises, architects can learn to prioritize the tree-building relationship and create innovative designs that incorporate trees. He also discusses the importance of public perception, policy changes, and the role of well-being in the tree-building relationship.

Christine Figgener, a world-renowned marine biologist, discusses her passion for sea turtles and the importance of their conservation. She shares her journey to Costa Rica and her first impressions of the research station. Christine explains that there are seven extant species of sea turtles, each with unique characteristics and diets. She emphasizes the role of sea turtles in maintaining the underwater ecology, such as the green turtle's grazing on seagrass and the hawksbill turtle's role in controlling sponge populations on coral reefs. Christine also touches on the declining numbers of sea turtles and the potential impact on the underwater ecosystem. Sea turtles play a crucial role in maintaining the health of our oceans. They are considered keystone species that help regulate the ecosystem. The green turtles keep seagrass matters in check, while hawksbill turtles control sponge growth on coral reefs. Sea turtles also contribute to the provision of food by feeding on jellyfish, which helps maintain the balance of larval fish populations. However, sea turtles face numerous threats, including climate change, habitat destruction, and illegal harvesting. The mating and nesting behaviors of sea turtles are still not fully understood, but efforts are being made to study and protect these processes. Volunteerism in sea turtle conservation can be both positive and negative, with some organizations exploiting volunteers for profit. The viral video of a sea turtle with a plastic straw stuck in its nose brought global attention to the issue of plastic pollution and the need for change. Despite the challenges, there is hope for the future of sea turtles, as they have shown resilience and the ability to recover if we make positive changes to protect their habitats and reduce threats.For more episodes in the Tree Lady Talks Archive click here.
