“…In the Pacific Northwest, two of the most high profile species, northern spotted owl (Strix occidentalis caurina) and greater sage grouse (Centrocercus urophasianus), provide examples of this pattern. The one most similar to the patterns observed for prairie-oak species is the northern edge of range extirpation of spotted owl from coniferous forests in southwestern British Columbia (Er et al 2005). An additional similarity is that many other spotted owl populations continue to decline, especially in the northern parts of its current range (U.S.…”

“…These definitions simply state that everything outside patches is considered matrix. In other interpretations, all urban green spaces are considered matrix, as remaining near-natural areas in a city are defined as patches (Er et al 2005;Palmer et al 2008). Normally, the term urban matrix is not precisely defined.…”

Despite the appearance of an enormous number of publications about urban ecology and species diversity, many issues are simply opened up rather than explained. The ecological complexity of urban areas, i.e., the variety of determinants and the spatial and temporal dynamic of cities, preclude simple starting points and lines of explanation. Therefore, we lack sufficient comparisons between various cities, especially comparisons on a global level. If cities are to be compared by appropriate indicators, and if they are to be evaluated with respect to urban biodiversity, then models are necessary that help us understand and mirror the causal relationships between urban areas and biological diversity. Three approaches, also representing a multiscaled view of urban areas, are presented that are suitable for developing applicable models and indicators for monitoring ecological systems: the embedded city, the urban matrix, and urban patches. The embedded city represents a globally useful concept, because the relationship between cities and their regions can be applied as an indicator to all regions. The lack of sufficient description of the urban matrix makes comparisons between cities difficult and causes scientists to underestimate the importance and function of the matrix for urban biodiversity. Urban patches are often investigated in urban studies about plants and animals. Therefore, much existing data can be used, and several criteria describing the functions of patches for biodiversity are available. In particular, the first two approaches should be researched more intensively.

Urban domestic gardens (XI): variation in urban wildlife gardening in the United Kingdom

et al. 2007

Two consequences of the continued urbanisation of the human population are that a growing proportion of the landscape is less hospitable to, and that a growing proportion of people are disconnected from, native biodiversity. One response of the UK government has been to establish a goal, and an associated baseline indicator, of increasing the extent and range of public participation in gardening for wildlife. The formulation of policy to attain this end requires, however, insight into the factors that are associated with the level of participation. Here we examine the relationships, across 15 areas in five UK cities, between the proportion of households providing various garden features for wildlife or participating in various wildlife gardening activities, and housing densities and characteristics of the garden resource. We show that significant numbers of households participate in some form of wildlife gardening, but that the predominant form this participation takes is feeding wild birds. Key variables associated with spatial variation in wildlife gardening activities are the proportion of households with access to a garden and, more importantly, average garden size and the proportion of land cover by gardens. There was no evidence for strong effects of household density or the socio-economic status of householders on the prevalence of wildlife friendly features in gardens or on the participation by householders in activities to encourage wildlife. Our results suggest important considerations in attempts to increase awareness and participation in wildlife gardening.
