How to Conquer Air Potato: Air Potato Roundup Results

Thanks all the volunteers who helped gather air potatoes and pick up trash. We only found about 15 potatoes! This means that we are finally on top of this tenacious exotic plant after 6 years of spring roundups and about 3 years of summer herbicide applications on the vines!!!! Persistence pays off.

Ed Rutherford deserves much of the credit for spraying vines and picking potatoes on a regular basis. Ed we at Duval Audubon really appreciate you efforts. Thanks for all your help at Crosby.

6th Annual First Coast Air Potato Round-up

6th Annual First Coast Air Potato Round-up on Saturday March 3rd from 9:00 a.m. – 12:00 p.m.

Please join us for this annual event to help control invasive air potato vines and maintain the sanctuary.
Lunch and drinks will be provided for all volunteers!

Volunteers are needed to help rid our natural areas of Air Potato vine and other invasive plants. Invasive species smother our native plants and are one of the greatest ecological threats to natural communities in Florida.
Gather all your friends and family & participate in this fun event! No registration necessary unless you’re bringing a large group. Just head over to one of the many work sites! Prizes awarded for the two largest potatoes found!

FOS Yellow-rumped Warblers Arrive at Crosby

Numerous "first of season" Yellow-rumped Warblers were observed by Pete Johnson at Crosby on October 26, 2011! We were out there for our monthly work session from 8 a.m. to 11 a.m. It had been raining early in the morning, so nobody else showed up except for Ed Rutherford and myself.

As usually happens, when the weather is bad the birding is good. I observed about 30 different species of birds in a couple hours, then entered species/numbers count data in eBird.org when I got home!
