Work at the Pū‘ali Wetland will be focused on controlling the seashore paspalum (“opae grass”). We needed this non-native grass initially to help contain the sediment, but it has proven to be too invasive and will crowd out the native plants if allowed to grow unchecked. We aim to control this grass without the use of herbicides by first cutting it down and then covering it with black plastic to prevent further photosynthesis. This method has been used successfully elsewhere in Hawaii.
Volunteers are needed, especially those handy with a weed wacker. We have three gas powered machines, but if you have your own weed wacker, please bring it. We plan to work no more than 3 hours this Saturday and should be done before lunch. If you can kokua, please bring your own water and snacks, because we will not have that support this month.
