“…Contributions of alien taxa to the total composition of urban flora are typically high (McKinney and Lockwood, 2001), and studies evaluating the role of alien taxa in cities have mostly focused on their spatial distribution (Miller and Winer, 1984;Roy et al, 1999). On the southeast coast of the Spanish Iberian Peninsula, Dana et al (2002) found that urban vegetation could be grouped into five ecological groups as a function of water availability and the frequency and intensity of disturbance.…”

“…In the literature experimental data about the biomass factors are present too, but only for a few vegetative species and with different units of measurement. Miller and Winer (1984) have measured the biomass factors for about 50 vegetative species, in units of g m -3 and kg tree -1 . Simpson et al (1995), on the other hand, report the biomass factors in units of g m -2 for four vegetative categories.…”

This work describes a methodology to estimate NMVOCs from vegetation in the Lombardy region. The proposed method is a 'bottom-up' one: starting from local data, at a municipality level, emissions have been estimated across Lombardy. By changing the different land use species assignment and the other site-specific inputs, it is possible to apply this methodology to any area. Two NMVOC pollutants have been considered: isoprene and monoterpenes. Their emissions have been computed using both Tingey, modified by Pierce, and Guenther algorithms. Isoprene and monoterpene emissions reach their highest values during the summer when the temperature, solar radiation and the foliage biomass are at a maximum. In the Lombardy region, the isoprene and monoterpenes estimate is about 200 tons/day; the CORINAIR '90 estimate is about 50 tons/day. Unfortunately the most sensitive input data, i.e. the emission rates and the biomass factors, are the ones with the highest uncertainty.

“…Although such an inventory can work well for small tree populations (e.g., street trees and those in small parks), it is expensive for larger tree populations so random sampling is generally applied as a cost-effective way to assess urban forest structure, function, and value for large-scale assessments [12]. There are various sampling techniques to assess urban forests, but most use a form of random sampling (e.g., [18][19][20][21][22][23]). The U.S. Forest Service has developed a specialized tool to perform such evaluations, the i-Tree Eco model (formerly known as the Urban Forest Effects (UFORE) model) (www.itreetools.org).…”

Assessing Urban Forest Structure, Ecosystem Services, and Economic Benefits on Vacant Land

An urban forest assessment is essential for developing a baseline from which to measure changes and trends. The most precise way to assess urban forests is to measure and record every tree on a site, but although this may work well for relatively small populations (e.g., street trees, small parks), it is prohibitively expensive for large tree populations. Thus, random sampling offers a cost-effective way to assess urban forest structure and the associated ecosystem services for large-scale assessments. The methodology applied to assess ecosystem services in this study can also be used to assess the ecosystem services provided by vacant land in other urban contexts and improve urban forest policies, planning, and the management of vacant land. The study's findings support the inclusion of trees on vacant land and contribute to a new vision of vacant land as a valuable ecological resource by demonstrating how green infrastructure can be used to enhance ecosystem health and promote a better quality of life for city residents.
