Deadwood Crown – Urban Biodiversity Booster

The Deadwood Crown is an urban biodiversity booster that consists of logs. It provides a home for many species of flora, fauna and fungi and a place for relaxation and reflection for us humans.

The Crown is composed of deadwood logs of different sizes and ages and in various stages of decay. The logs come from trees that are cut down in the urban area, for instance during park maintenance or when clearing a construction site. In a two year interval, new logs are added to the installation to maximise the diversity and to ensure the continuation of the decomposition processes. The logs are connected to each other with stainless steel bolts so that the whole installation is easy to dismantle and move to a new location if necessary.

The Crown provides a microhabitat for fungi, mosses and lichens, various insects and birds. It also works as a catalyst base station for the biosphere of nearby parks, balcony gardens and urban forests.

For the local residents the Crown provides a glimpse in to the natural cycles of growth-death-decomposition and nutrient cycling. It is interesting to watch the installation change through the years and to see which animals and plants find home in it. The Deadwood Crown is a biodiversity hotspot right at your doorstep.

Messages from Islands – A Global Biodiversity Tour

Messages from Islands – A Global Biodiversity Tour (Tutkimusmatkoja saarille – luonnon monimuotoisuutta kartoittamassa in Finnish) is a marvellous book by the late Finnish biologist Ilkka Hanski. In the book he combines a personal memoir and scientific research into an eye opening read. Hanski talks about evolution, conservation and biodiversity based on his trips to several islands all across the globe. His passion on the subject and the personal descriptions of the journeys make the book a joy to read. Of course it is also sad to read about the biodiversity collapse during the last decades Hanski. Hanski really makes strong points on why we should act now and save what we can.

Urban domestic gardens (II): experimental tests of methods for increasing biodiversity

Experiments in Increasing Urban Biodiversity

This interesting article by Kevin J. Gaston, Richard M. Smith, Ken Thompson and Philip H. Warren provides insight in increasing urban biodiversity via experimental methods in urban domestic gardens. Some of the methods, such as adding nesting places for solitary bees and introducing small ponds, seem to succeed well while some other methods yield no significant success. The subject is very closely related to Nature Cots since it is essential to find ways and means that are actually effective in boosting urban nature.
