Kappaphycus Control and Remove Plots: data from control plots and from plots where we removed the alien alga Kappaphycus and monitored regrowth or overgrowth of coral every month by taking photos with a digital olympus30/30 camera mounted on a pvc frame. For each species, the numbers represent percent cover in the photoquadrat.

Why was the data set created?

To assess the potential to use native sea urchin's as biocontrols for alien/invasive seaweeds and to monitor the regrowth of Kappaphycus.

How was the data set created?

1. From what previous works were the data drawn?

2. How were the data generated, processed, and modified?

   Date: Unknown (process 1 of 1)

   One species of urchin, tripneustes gratilla, were placed in a 1/4 m2 plot with > 50% kappaphycus cover. Fences were made out of plastic coated chicken wire and were surveyed every month with photoquadrats to assess kappaphycus abundance.
