How does urban forestry and green infrastructure help prevent soil erosion and flash flooding?
A healthy urban forest can lessen the amount of runoff and pollutant traveling into in receiving waterway in several ways. First, through evapotranspiration, trees soak up precipitation from the soil, thus increasing soil water storage potential. Leaves, branch surfaces, and trunk bark deflect and store rainfall, thereby reducing runoff volumes and slowing down the rush of peak flows. Also, fauna and flora decomposition along with root growth increase the capacity and rate of soil infiltration by rainfall and reduce overland flow. This is why flash flooding is usually seen in concrete and urban environments. Lastly, healthy tree canopies contribute to the reduction of soil erosion by diminishing the impact of raindrops on barren surfaces.

Harmful algae blooms or HABs occur naturally, but what kind of human activities disturb ecosystems enough to cause devastating anthropogenic algal blooms?
Increased nutrient concentration and pollution, food cycle disruptions, introduced species, water flow disruptions, and climate change all contribute to algae blooms. They occur when nutrients (mainly phosphorus and nitrogen) from sources such as landscaping and agriculture become runoff, entering river, ponds, stream, and oceans. These nutrients become concentrated at a rate that “overfeeds” the algae which naturally exist in the environment. Some HABs appear in the aftermath of natural phenomena like stagnant water circulation, water temperature change, and extreme weather events like hurricanes, floods, and drought.
