Abstract

This thesis addresses cities’ growing emphasis on urban green spaces and the need to protect public safety by assessing tree health and structural stability. Using Aalborg Municipality as a case, it investigates whether and how Visual Tree Assessment (VTA) can reinforce the current practice, which relies on four broad vitality levels with vague symptom criteria. The study contrasts VTA with existing approaches such as Static Integrated Analysis (SIA), discusses the risks of pruning, and highlights VTA’s non-destructive, visual approach that can reveal decay and defects often missed by other methods. To understand potential barriers to changing established routines, the Multi-Level Perspective (MLP) is used as the theoretical lens. Methods include desk research, email interviews with Aalborg’s Park and Nature department and a professional arborist, and photo-based visual analysis; instrumental checks and digital tools for cataloguing are also considered. COVID-19 imposed major constraints, notably the lack of in-person interviews and slow response times. The thesis aims to clarify the potential benefits of VTA for municipal tree management and the organizational and professional challenges that must be addressed for possible implementation.

Dette speciale tager udgangspunkt i byers voksende fokus på grønne områder og behovet for at sikre borgernes sikkerhed ved at vurdere træers sundhed og stabilitet. Med Aalborg Kommune som case undersøges, om og hvordan Visual Tree Assessment (VTA) kan styrke den nuværende metode, der i dag bygger på fire overordnede vitalitetsniveauer med uklare symptomkriterier. Specialet sammenligner VTA med eksisterende praksisser som Static Integrated Analysis (SIA), diskuterer risici ved beskæring og fremhæver, at VTA tilbyder en ikke-destruktiv, visuel tilgang, der kan afsløre tegn på svækkelse, som ofte overses. For at forstå mulige barrierer for at ændre en etableret praksis anvendes Multi-Level Perspective (MLP) som teoretisk ramme. Metodisk bygger studiet på desk research, e-mailinterviews med Aalborg Kommunes Park og Natur samt en professionel arborist, og en fotobaseret visuel analyse; derudover overvejes støtte af instrumentelle målinger og digitale værktøjer til katalogisering. COVID-19 medførte væsentlige begrænsninger, herunder fravær af fysiske interviews og længere svartider. Specialet har til formål at klarlægge, hvilke forbedringer VTA kan bringe til kommunal træforvaltning, samt hvilke organisatoriske og faglige udfordringer der skal håndteres for en mulig implementering.
