Trees in the forests live with their family and friends. Above the ground, young trees are protected by mature trees against extreme weather conditions such as scotching sunlight, damaging wind, and extreme cold. Equally and maybe more important than the above ground partners, the underground partners in insects, worms, and root and soil microbiome is critical for the survival and thrival of the baby trees. In the natural forest, it is easily passed on from the mother trees to the offsprings.
What do we have in urban environment: striped off top soil, compacted soils, excess stormwater runoff from impervious surfaces, salt, pollution, insecticides, herbicides, fungicides and more. With all the above, how many of the beneficial microorganisms are still there? And how can we expect these urban trees to survive and thrive! Even we get a few survivors, is there any food (organic matter), oxygen, and moisture for them to survive and thrive? In this talk, we will review the partners urban trees are missing and how we can bring them back.
