No there is not any security at the park. I was there leading the CCPS Spring Meetup with Ozzy Saturday afternoon and there were many young children oohing and aahing at all the venus flytraps and pitcher plants. And Millipede is right they only took a little over 1,000 vfts not 10,000.
Unfortunately events like this are all too common. We also visited the famous Shaken Creek that day and there were S. purpurea pitchers cut off and strewn about everywhere with many holes all over. It is truly unfortunate that people feel the need to destroy plants like this. The next day we were in Croatan National Forest visiting one of my favorite locations for S. rubra ssp. rubra and I found a few holes where there used to be plants. It is truly unfortunate when people cannot just let nature be for all to enjoy.
