It has almost been 3 weeks since Bobby and I began working on Ship Island. Unfortunately we are still not seeing as many terns as we should, and we don’t have a good explanation as to why. As Bobby explained last Thursday the refuge came out and installed a sound system and decoys in an attempt to lure more terns to Ship Island. In the meantime the past week we spent a considerable amount of time implementing invasive plant control on Garlic Mustard (seen in the picture below).

This work is very familiar to me since all last summer I worked as a invasive plant control intern out in southern CO for the San Luis Valley National Wildlife Refuge Complex.  Garlic Mustard is a particularly nasty invasive since it is also allelopathic meaning it releases chemicals that can inhibit the growth of other plants surrounding it allowing it to grow out of control and take over huge areas of land that could otherwise been used by native plants that provide a service to the ecosystem. The method of control that we implemented with the refuges help last Tuesday was to first pull all flowering plants, and spraying  the area where the plants where pulled with extra strength vinegar which will hopefully kill any seeds that could be dormant in the soil. We also sprayed little roseate that would turn into flowering plants the following year. Bobby and I spent the next day scouring the island further to find as many of the plants that we could. We were pleased to find that the infestation at least this year was confined to only a few areas on the island instead of spread out. The work can be difficult at times trudging through fields of Cow Parsnip and stinging nettle both which can leave painful rashes on the skin, but trudge on we will.
