FOR200H1 Lecture Notes - Lecture 2: Sodium Chloride, Urban Forestry, Ecological Land Classification
Document Summary
Urban forests: are trees, forests, green space, and the related abiotic, biotic and cultural components in areas extending from the urban core to the rural fringe. For every 1 meter of forest canopy, 0. 61 m3 is needed of soil. We must plan for adequate growing space. Sudbury is an example of poor soil quality, inadequate quantity, and then successful ecological remediation. Even-aged forests are the most common in cities due to monocultures. Family, genus, species, genotype and the 10-20-30 rule . You shouldn"t have one species making up more than 10% of the forest. You shouldn"t have more than 20% of one genus present. You shouldn"t have 30% more of one family in a forest. Many of the trees planted in the urban forests are clones. This reduces the resilience of the forest and the adaptability of trees to disease as they"re all equally susceptible. Must ensure that nonnative species aren"t invasive. Tree conditions and health are not considered.
