Join the 2026 City Nature Challenge!

We are excited to announce that LIISMA is partnering with the iNaturalist ambassador program to support the first-ever City Nature Challenge (CNC) on Long Island!

What is it?

The City Nature Challenge is a global community science “bioblitz” organized by the California Academy of Sciences and the Natural History Museum of Los Angeles County. The goal is to document as many wild organisms as possible to create a massive open-access database of local biodiversity.

Event Details

Dates: April 24th – April 27th, 2026

Location: Anywhere on Long Island! (Your backyard, local parks, or nature preserves)

How to Participate: Simply take photos of wild plants, animals, and fungi and upload them to the iNaturalistapp.

Why Participate?

By joining in, you help scientists and conservationists (like us at LIISMA!) better understand our local ecosystems. Your observations help us track native species and identify the spread of harmful invasive species across the island.

Get Involved

Follow the Project: Check out the official iNaturalist project page for live updates.

Stay Connected: Follow the City Nature Challenge Long Island Instagram for tips and highlights.

Emerald Ash Borer Awareness Week Webinar Series: Resistance to EAB is real – here’s what we can do to help restore ash in the future
2026-05-19 11:00 - 12:00
Presentation by: Carolyn (Carrie) Pike, Regeneration Specialist, USDA Forest Service, Eastern Region – State Private and Tribal Forestry

Emerald ash borer has decimated eastern forests, especially in lowland or riparian forests where green ash is dominant. I will discuss how resistance breeding may help us retain ash on the landscape in a post-EAB world and share findings of a recent publication (Mason et al. 2026) that demonstrated heritable resistance in green and white ash.

Emerald Ash Borer Awareness Week Webinar Series: EAB from crisis to opportunity: managing & growing a resilient urban forest in Minneapolis, MN
2026-05-21 13:00 - 14:00
Presentation by: Philip Potyondy, Smart Tree Management Practice Lead, Davey Resource Group, Inc

The loss of ash trees to Emerald Ash Borer was a major opportunity to establish a more diverse and resilient urban forest. This generational opportunity was not squandered. Learn how Minneapolis used thoughtful, deliberate, multi-scaled tree selection guidelines to select a diverse mix of trees, even with considerations for future forest pests and a changing climate. Philip will also share a few key takeaways while managing the spread of EAB and also about a few new technologies for monitoring the urban forest and assisting with tree selection
