What is EDRR?

So you're out in the field during an ordinary workday, and you come across an unfamiliar plant. You're worried that it might not be native to the area, or perhaps you know of it and you're aware that it's non-native or invasive, but this is the first time that you've seen it in your specific work area.

What do you do?

Early Detection & Rapid Response is a methodology through which stewards can be proactive, vigilant, and effective in identifying, documenting, and eradicating non-native and invasive species. It's important that we as responsible land managers have an awareness of where these species have appeared, how established their presence is, and which species we should prioritize in our removal efforts.

Luckily, there are organizations out there that make this work a priority. Through documentation and communication of non-native and invasive species threats, we can all be better informed about the current status of our work areas and can plan our stewardship efforts accordingly.


Step 1: Identification

Of course it is important to be well-versed in methods of identifying non-native and invasive species. We've included a few resources below, and we encourage you to share your favorites with us and with your peers!

Step 2: Documentation

So now you are aware of this new unwelcome guest, and your efforts may adjust as such. However, it's important that we are ALL aware of these occurrences, because if we know that a certain species has appeared in a nearby area, we can be on the look out and perhaps catch the next establishment before it gets out of hand.

Here are a few resources that we've found helpful in making this information accessible to the broader stewardship community. Again, if you have any that have been particularly helpful to you, please share them with us and with your peers!

Step 3: Disposal

As with any non-native or invasive species, it's important to understand its methods of reproduction in order to properly dispose of it without facilitating further spreading. As with your usual challenge activities, we encourage you to research the laws and policies of your specific geographies to be sure that you are following proper protocol for disposal. If you encounter a new species, it might be worthwhile to be sure you're up to date on this information.
