Structural elements as barriers against wear in urban woodlands

The aim of this study was to improve the knowledge available for urban planning and for improvements in urban forestry by (1) examining the barriers (standing and fallen trees, shrubs, rocks, topography, and other obstacles) that are found in urban woodlands, (2) studying the amount of spontaneous paths (or worn out area) and their level of wear, and (3) determining whether the barriers play a role in directing peoples movements.

"The effect of structural elements of woodlands (trees, rocks, topography, etc.) on the spatial distribution of wear was studied in 30 sites in the cities of Helsinki and Vantaa, Finland. Discriminant analysis showed that the size of the adjacent human population and structural elements within study sites were important in distinguishing sample plots with a lot of path area (6 m2/30 m2) from those with little or no path area (>6 m2/30 m2). The higher the structural elements, the more effectively they functioned as barriers against wear. Thickets of small trees (dbh > 10 cm), topographical elements, and fallen trees seemed most effective, and big trees (dbh 10 cm) least effective as barriers. It was concluded that natural barriers could be used to limit wear in urban woodlands." [Abstract]
