1.1 Synanthrope
NOVEL CONDITION OF COHABITATION
City are refuge for rare species, so much so that they may be able to preserve at least some of the biodiversity that is disappearing ever more rapidly elsewhere. Modern agriculture is highly intensive in its use of land, creating monoculture and adding herbicides and pesticides, which destroys the soil and as a consequence less species could survive.
Synanthrope species, which have an indirect relationship with human resident of cities, occupying the boundary between domestic and wild, establishing novel conditions of coexistence.
Jocey Hwang - A 10-Point Manifesto: Interventions
Synanthrope species are ecologically associated with and even evolve to become entirely dependent on humans.
Other species simply tolerate cohabiting around humans and using the remaining urban free space and urban structure as habitat, in some cases gradually becoming sufficiently accustomed around humans to also become synanthropic over time. These species represent a minority of the creatures that would normally inhabit an area. 8% of native bird and 25% of native plant species were present in urban areas compared with estimates of non-urban density of species.

Jocey Hwang - A 10-Point Manifesto: Interventions
“the biodiversity of a facade is much higher then a monoculture field.”
Any vulnerabilities in the building enclosure, such as vents and chimney openings, provides these species with entrance into heated attic spaces and wall cavities beyond. These conditions unintentionally invite species to cohabitate in unwanted and sometimes dangerous ways.
popularity degree - AAD
City Zurich contains approximately half the wild plants mammals birds and battles, lacertilian found in Switzerland. But we should not harbor illusions. In a city, many species fight hard to survive and to settle.
In the past, many swiftcolonies were mainly high cliffs, but today they breed almost only on anthropogenic structure. Many swiftcolonies, which had found shelter in apartment buildings from the 1930s - 1950s, have become homeless because the buildings were replaced by “Ersatzneubau”.
The constant decrease in breeding sites inevitably leads to a population decline of swifts

Is there a way of peaceful cross species cohabitation? who are we agent for and whos proporty are cities?
