About Exploration Green
In Southeast Houston, dedicated groups of volunteers are transforming a defunct golf course into an innovative stormwater detention center and green space.
Exploration Green provides an integrated, natural solution for catastrophic seasonal flooding holding up to 500-million-gallons of stormwater while also serving as a nature preserve and recreation area. Located near NASA's Johnson Space Center, this 200-acre urban green space provides the community with countless opportunities to explore, offering 40 acres of both wetlands and permanent detention lakes, home to over 1,000 native species.

Discover what species of moths and other night-flying insects are out and about in Exploration Green!
Exploration Green had a great response to Moth Night 2021, so we are bringing it back in 2022! In fact, we are hoping this will be the first of several Moth Nights this summer, to give people more options in case they cannot attend on a given night.
We will set up white and UV lights shining on white sheets to attract them where we can then view and photograph. In the days after the event, we will upload our observations to iNaturalist for identification and so that we can track the species we have found over time.
Just a reminder that there are no lights installed in Exploration Green, it will be fairly dark between the parking lot and the mothing area. Please also note Exploration Green has no restroom facilities.

HOUSTON — Exploration Green is a community project in Clear Lake that serves two purposes. When the weather is nice, it’s a place where neighbors can connect with nature. When storms hit, it keeps nature away from neighbors.
