Documenting the plants, animals, habitats, and ecology of the Sligo Creek watershed (past and present); pursuing habitat improvements; and providing educational experiences through nature talks and outings.

Natural History Committee Projects

FOSC’s Natural History Committee helps us humans near Sligo Creek Park appreciate the variety and abundance of plants and animals with whom we share the watershed. We do this by promoting citizen sightings of Sligo wildlife, documenting the flora and fauna of Sligo, advocating for new natural areas, helping to conserve existing ones, and organizing talks and outings about our diverse habitats and the many living things that inhabit them.

Leave the Leaves in your yard

Why? Kit Gage, FOSC Advocacy Director, explained why: to enrich the soil, and give butterflies and other insects, small mammals, toads, salamanders, and other critters a place to overwinter.


  • Leave some leaves on your lawn and let them blow into your garden beds, where they will decompose over the winter, enriching your soil far better than a bag of mulch. Push the excess into a corner of your yard. Your plants, and the critters thank you too.
  • Shred your leaves with your mower and leave them on your lawn and in your garden beds. Really.
  • Use a vacuum blower/shredder to collect and shred excess leaves, and a bin to keep them handy for adding to your compost bin.
