EDDMapS: A Citizen science Tool for Invasive Species Management

Invasive species pose a important threat to ecosystems, economies, and even human health. Early detection and rapid response are crucial for effective management, and thatS where EDDMapS (EDDMapS.org) comes in. This online platform empowers citizens,professionals,and land managers to report and track sightings of invasive plants and animals across the United States and beyond.

What is eddmaps?

EDDMapS stands for Early Detection & distribution Mapping System. It’s a collaborative, web-based mapping system that collects and shares observations of invasive species. The data collected through EDDMapS helps scientists and managers understand where invasive species are present, how they are spreading, and prioritize control efforts. It’s a powerful example of citizen science in action – meaning it relies on contributions from people like you to gather valuable data.

Why Report Invasive Species?

Reporting sightings isn’t just about adding a pin to a map.it provides critical details for:

• Early Detection: Identifying new infestations before they become widespread is the most cost-effective way to manage invasive species.
• Distribution Mapping: Tracking the spread of invasive species helps understand their dispersal patterns and potential impacts.
• Prioritization of Control Efforts: Data informs where to focus limited resources for eradication or containment.
• Research: Scientists use EDDMapS data to study invasive species biology, ecology, and potential control methods.

Current Data Needs: A Focus on the Pacific Northwest

while eddmaps boasts a wealth of data across many regions,some areas are underreported. Currently, there’s a notable need for more observations in Portland, Oregon. In contrast, Vancouver, Washington, already has a substantial number of reported sightings, especially for Tree-of-Heaven (Ailanthus altissima).

tree-of-Heaven is a particularly concerning invasive tree known for its rapid growth, allelopathic properties (it releases chemicals that inhibit the growth of other plants), and its role as a host for the Spotted Lanternfly, a highly destructive pest. Increased reporting in Portland will help track its spread and inform management strategies.

How to Report sightings

Reporting a sighting on EDDMapS is easy:

1. Create an Account: Visit eddmaps.org and create a free account.
2. Verify the Species: Accurately identify the invasive species you’re reporting. EDDMapS provides resources to help with identification, including photos and descriptions. If you’re unsure, submit a photo with your report.
3. Submit Your Observation: Use the online mapping tool to pinpoint the location of the sighting. Include details such as the abundance of the species, the size of the infestation, and any relevant photos.
4. Verification Process: Submitted observations are reviewed by local experts to verify the identification and location.

Beyond Tree-of-Heaven: What Species to Watch For

EDDMapS tracks a wide range of invasive species. Here are a few examples of species to be aware of in the Pacific Northwest:

• Spotted Lanternfly (Lycorma delicatula): A serious threat to fruit trees and vineyards.
• Japanese Knotweed (reynoutria japonica): An aggressive plant that can outcompete native vegetation.
• English Ivy (Hedera helix): A climbing vine that can smother trees and disrupt ecosystems.
• European Starling (Sturnus vulgaris): An invasive bird that competes with native species for nesting sites.
