AbstractWith increasing urbanization and environmental degradation, urban landscapes are increasingly expected to provide a wide range of ecosystem services typically associated with rural areas, including biodiversity conservation and food production. Because residential landscapes constitute the largest single urban land use, domestic gardens have emerged as a topic of research interest and planning concern. The ecosystem services (or disservices) these landscapes provide, however, have not been rigorously measured, nor have tradeoffs between the services they provide been assessed. In this study, semi-structured interviews were conducted with 59 African American, Chinese-origin or Mexican-origin households with on-lot or vacant lot food gardens in Chicago. Crop plants and cultivated ornamental plants on the lot were inventoried and mapped at the species level. A total of 123 edible plant taxa from 25 families and 288 ornamental plant species from 85 families were identified, for a combined total of 387 species from 90 families. Cumulatively, the gardens of African American households were relatively rich in ornamental plant species and families, while those of Chinese-origin households had a depauperate flora. Crop plant richness was more even across sample types. Shade trees and a developed shrub layer were absent from most gardens, possibly representing a tradeoff in ecosystem services in favor of food production. The richness of the aggregate 2.1 ha of residential property inventoried in this study was comparable with or exceeded that of a 34 ha prairie remnant west of Chicago. However, only 35 (9.6%) of the inventoried species were native to the Chicago area.

A taxonomic survey was carried out to assess the diversity of plant genetic resources in the Horticultural farm of Bangladesh Agricultural University, Mymensingh. The data were collected during April 2004 to March 2005. A total of 25328 (including unidentified plant species) species were recorded in which trees, shrubs, herbs, climbers and woody grasses were 51.56, 27.60, 7.81, 10.41, and 2.61% of the total species, respectively. The total number of plants belongs to 98 families under 141 genera and 192 species (excluding unknown species). Among these, 65 fruit tree species under 38 genera and 25 families (of which 8 species were rare and endangered), 16 timber plant species under 12 genera and 9 families, 32 medicinal plant species under 29 genera and 24 families (of which 7 species were rate and endangered), 44 ornamental plant species under 34 genera and 25 families (of which 2 species were rare and endangered), 4 spices plant species under 4 genera and 4 families, 11 vegetables plant species under 9 genera and 6 families, 5 bamboo species under 2 genera and one family, 3 rattan (Bet) plant (which were rare and endangered) species under one genus and one family, 10 palm plant species under 10 genera and 2 families, and 2 rubber plant species under 2 genera and one family were recorded.

Levels of lead, cadmium, and nickel in roadside soils and vegetables along a  major highway in Gazipur, Bangladesh were investigated. Soil samples were  collected at distances of 0, 50, 100, and 1000 m (meter) from the road. The  concentrations of lead (Pb) and nickel (Ni) in soil and vegetables (bottle gourd  and pumpkin) decreased with distance from the road, indicating their relation to  traffic and automotive emissions. The concentration of cadmium (Cd) was found  to be independent of distance from road. There were significant differences in  the concentrations of lead, cadmium, and nickel for different plant species and  soils at various distances. The heavy metals contents both in the soils and  vegetables for every distance from the road was found in the order  nickel>lead>cadmium. DOI: http://dx.doi.org/10.3329/bjar.v37i1.11170 Bangladesh J.
