PAST EVENT: “Bird Outing”
June 19 -Bird outing with Dave Blockstein and Mary Sanger. Information about the birds sighted at this event is coming.
PAST EVENT: “Cicada Party”
June 5 – John Lill, Biological Sciences Dept chair at GWU, and Diane Lill, Greenkids Program Director at the Audubon Naturalist Society, led a walkabout at the Sligo MS baseball field. About 50 people joined John and Diane as they illuminated the intricate lives of the cicada subspecies participants found onsite. Check out the story and photos on the Natural History page.
PAST EVENT: “Spotlight on Native & Invasive Vines of Sligo / Virtual Tour of Sligo Meadow & Restoration Projects”
Ever see vines looping and climbing from tree to tree in Sligo? What makes these 3 native vines – Native grape, Virginia creeper, and poison ivy – so important to Sligo Creek and park? Food and shelter for wildlife and the fact that they do not strangle the trees they climb on, explained Corinne Stephens, director of MoCo Parks’ Weed Warrior program.
In contrast, Non-Native Invasive (NNI) vines bind trees and eventually kill them. The 8 Non-Native Invasive vines that Weed Warriors are authorized to remove from Sligo are:
Dianna Loescher, Senior Natural Resource Specialist at Parks, led a virtual tour of the Sligo meadow and restoration projects, highlighting the techniques and plantings that are working and those that have been revised as site data is gathered.Check out her presentation here.
Our thanks to Corinne and Dianna for great presentations!
PAST EVENT: “Less Lawn, More Life”
Merikay Smith, of the Master Gardeners Speakers Bureau and the Muddy Branch Alliance board, described the process of converting her lawn into a native plant habitat that supports a diverse array of wildlife. Her neighbor joined in, converting parts of their lawn too.
She recommends starting by assessing what you have already – is it native or not, is it a non-native invasive or not? Take out the non-native invasives first! Some other elements of a habitat to incorporate are:
–Plant a full stand of a native – too little and birds who are attracted to nest near it are unable to feed their young for lack of food (chicks don’t eat seed, they eat caterpillars or other insects, so plant enough so there’s insects to feed the brood.)
–Put a water source – can be a simple dish you pour out and replenish every few days.
–Make changes by starting with the corners, and then the edges of your property.
–Start in a corner(s) by planting a native tree – these are the circles on a plan. Oaks are superstars. For example, a Black Jack Oak supports 500+ species of insects
–Then connect the circles with beds along the edges.
–Site prep – build beds by covering a lawn area with cardboard, then compost and mulch, in the fall. Don’t dig!
–Fully research the species / cultivars you plan to plant since many seem native (with “virginiana” in the name, for example) but aren’t genetically native and a host for local insects.
–Focus on keystone plants – those that sustain the food web of plants-insects-birds:
Keystone trees: White Oaks are superstars; Native Cherries, Native Willows, Native Birches, Cottonwoods, Elms
Keystone herbaceous plants: Native Goldenrods, Asters, and Sunflowers.
PAST EVENT: Improving Outreach and Inclusion
Our watershed is diverse in so many ways. We recognize that we need to reach out thoughtfully and more effectively to be inclusive of all Sligo watershed communities in outreach, programming and leadership.
On March 25, three leaders in the Black and Latino environmental movement discussed their perspectives on how Friends of Sligo Creek can engage the diverse communities living within the watershed.
(l to r) Ruby Stemmle, founder EcoLatinos; Raymond Coates, Community Outreach Coordinator, Ward 8 Woods and EarthJustice; and Dennis Chestnut, founder Groundworks DC, and Board, Alliance for the Chesapeake
Moderated by FOSC Advocacy director Kit Gage, the panelists discussed the importance of developing relationships with the communities who have been underrepresented in FOSC’s work; learning about the issues important to those living in the community; and tapping residents to develop and lead initiatives in those communities. A synopsis recording of the discussion is available below from the FOSC YouTube channel.
PAST EVENT: How to use iNaturalist
Heard about iNaturalist.org but uncertain how to navigate the site or contribute your own observations? Expert birder and iNaturalist contributor Stephen Davies recently gave a tour through the many features of this site. He used the iNaturalist project “Fauna and Flora of the Sligo Creek Watershed” as a starting point.
iNaturalist is an open-source, joint initiative of the California Academy of Sciences and National Geographic. It has world-wide scope, with 3.5 million people contributing 57.8 million observations to date.
Users can upload their observations, keep track of their photos, crowdsource identifications, join citizen science projects, see trends and build knowledge of the natural world. Creating an account at iNaturalist is simple and free.

PAST EVENT: What’s in Sligo’s Water?
Membrs of the Water Quality committee – Anne Vorce, Pat Ratkowski, Paul Chrostowski – and guests Mike Smith, FOSC President, Elaine Lamirande from the FOSC Stormwater Committee, Kit Gage from the Advocacy Committee, and Rachel Gauza from the Park Dept’s Aquatics Resource Management office presented a fascinating glimpse into the state of water quality of Sligo Creek today and trends over time.
