Independent Tree Surveys & Arboricultural Advice across Wales and the UK
Hello, I’m Johann Wilsker, founder of Black Mountains Tree Consultancy. With over 20 years of experience in arboriculture, I provide clear, practical advice to help you make the right decisions about your trees. Whether you’re concerned about a tree’s safety, need a report for a mortgage or planning application, or want to understand how best to manage your woodland, I’m here to help.
As a fully qualified and insured consultant, accredited by both the Royal Forestry Society and Lantra, I specialise in tree safety and condition surveys, BS5837 planning surveys, subsidence and mortgage reports, tree inventories, and soil care. Based in Wales and working across the surrounding counties, my approach is straightforward: I listen to what you need, assess your trees with care and professionalism, and provide reliable reports you can trust.
