Biocontrol research and herbicide trials have been conducted but its still early to release results, is it worth it to continue monitoring the invasions while waiting for these two researches?
Yes, I think it is worth monitoring the invasion progress. Hard data on how the species expands or retreats can be very usefull to model which factors influence its expansion. On the long term they could be usefull to erradicate or at least reduce the expansion of the species.
You should definitely monitor the invasive plants' progress. You will need that information for optimizing future biocontrol approaches and research..
Thanks Victor and Javier, I have been monitoring Hydrilla invasion for the past three years and have identified factors influencing its expansion. But the general feeling was that the surveys are no longer yielding new results, I rather monitor control operations which are not yet exercised and its not clear when they will be exercised. Do you have examples of similar studies showing the benefits for long term monitoring?
