There have been issues with pests like the Dutch Elm disease and Emerald Ash Borer, which have led to the loss of a majority of elm and ash trees, respectively. Additionally, the harsh northern climate and the use of salt on roadways pose threats to tree health.
How is the City of Minneapolis addressing the issue of tree mortality and improving soil health?
-The City of Minneapolis is addressing tree mortality and improving soil health by incorporating biochar and compost mixes in tree plantings. They are also exploring the use of biochar in remediation projects, studying its effects on the bioavailability of lead and other contaminants in soil, and planning for local biochar production to support urban agriculture and forestry.
What is the role of biochar in the context of climate change resilience as discussed in the webinar?
-Biochar plays a role in climate change resilience by sequestering carbon, improving soil health, and enhancing the ability of plants to survive in periods of drought. It contributes to the development of more sustainable urban environments and helps in the adaptation of urban forestry practices to changing climate conditions.
What are some of the ongoing research projects and initiatives involving biochar mentioned in the webinar?
-Some of the ongoing research projects and initiatives involving biochar include a study on the bioavailability of lead in soil, a project to evaluate biochar's effect on PFAS and pesticides in waterways, the potential use of biochar in a geothermal application for district heating, and a collaboration with the Shakopee Mdewakanton Sioux Community for compost and biochar production.
