Minds in the Gutter: Urban Leaf Litter and Stream health

Dead leaves in a storm sewerThursday, October 8 – 7:00 – 8:00 p.m.
Natural History Society of Maryland

Contrary to popular belief, in most urban areas the tree canopy is significant. Most leaves drop in the fall, and find their way into storm drains and into streams, providing a large “gutter subsidy” of organic matter and nutrients to aquatic ecosystems.  This organic carbon takes many forms and is used by stream organisms throughout the food web.  Removing leaves from gutters can be a stormwater practice aimed at keeping nutrients out of the stream, but these can also be used as fertilizer for plants, e.g., in rain gardens.  Ken Belt has been studying the gutter subsidies and stream health for decades. Join us to learn what happens when forestry meets engineering and stream ecosystems.
This program is for adults. $5 fee. More information and registration can be found here.

green towson alliance virtual book group discussion

This Zoom event was held in June.

“Nature’s Best Hope” is the latest book by the UDel entomologist Doug Tallamy, who was one of the first people to realize that nearly all American insects can digest only American plants that they have co-evolved with for thousands of years. This was an incredibly significant insight because nearly all birds depend on insects – specifically caterpillars – to feed their young. If there are no caterpillars or insects, there will soon be no baby birds in our backyards and neighborhoods, and no baby birds bodes for a very bad future. “Nature’s Best Hope” is extremely thoughtful and full of the history of how Americans conceive of “nature” – that Nature is something that we should enjoy in a park setting, but which we have historically seen as something we must suppress or fight in order to survive. This, of course, is a very old and outdated paradigm, and it’s well past time for a change. Tallamy’s book has specific advice on how to cut back  the lawn and join with our neighbors to create what Tallamy calls a “Homegrown National Park”, a unique approach to rebuilding the natural world on the land we have some control over – our own private properties. If we work with our neighbors and each plant our landscapes to encourage insects, birds, pollinators and wildlife, we have a chance to restore our country’s great woodlands and prairies.
