Which Theories Address Biodiversity? Biodiversity is explicitly considered in
fractal geometry, the Biophilia Hypothesis, and the Ecosystem Service Cascade
Model. Fractal dimensions have been used to determine habitat quality (Imre and
Bogaert 2004), landscape structure and composition (Pe’er et  al. 2013), habitat
complexity (Dibble and Thomaz 2009) and species richness of an area (Stevens
2018). The Biophilia Hypothesis posits a preference for animals, plants and natural
environments, but it does not specify which species or landscape types are best for
fulfilling the biophilic need for connection to nature (Sundli Tveit et  al. 2013).
Further, the strongest work on the Biophilia Hypothesis is with its opposite, biophobia, the fear of specific animals and landscapes (Ulrich 1993). The Ecosystem

Restorative
environments are
characterised by
visual characteristics:
moderate complexity;
moderate depth; a
focal point; deflected
vistas (e.g. path
bending away); a
ground surface
conducive for
movement; lack of
threat; and water.
