Document Summary
Week 3 (4) urban forest ecology & restoration. Meeting of forest regions increased diversity: that"s why we have such great diversity in southern ontario. South-central ontario: boreal, glsl, carolinian, great lakes, st. lawrence, maritimes, northern limit carolinian. Scale can range from single tree to whole forest to region. Any event that disrupts a forest ecosys or part of a forest ecosys. Change in the species composition of a forest community over time. Can lead to a community in dynamic equilibrium that can persist indefinitely unless there is a disturbance (scale issues) Composition of the community is dependent on site-specific characteristics (e. g. , soil, moisture, disturbance) 1: inhibition model: early species inhibits growth of later species; change only happens w/ disturbance. We can apply a lot of the same principles from natural" forest ecology to urban forests too! More generalist species tolerant of human disturbance. More pollution (including light and sound pollution), invasive species, human traffic, litter, etc.
