The Galapagos National Park Service (GNPS) and the Charles Darwin Foundation (CDF), with support from local and foreign volunteers, have resumed a sea turtle monitoring program that measures a range of data related to the nesting season of this species.
The monitoring process has made it possible to record the number of females who come to deposit their eggs at popular nesting sites throughout the archipelago, assess the reproductive success of the species and its population status. Additionally, the program is observing the effects of human activity on sea turtle populations.
For the past seven years, the CDF has coordinated sea turtle monitoring. The GNP is now leading this process.The Galapagos are one of the main nesting sites of the green turtle Chelonia mydas. The species' survival is being threatened by fishing (the tortoises are often caught as bycatch), egg collection in regions outside Galapagos, and the negative effects of climate change on nesting sites. Global efforts are being made to assist the recovery of this species, and the GNPS is coordinating the conservation of these reptiles in the Galapagos archipelago.

While work is still ongoing, data collected during the first phase of the study suggest that the mariquita or Vedalia beetle, an Australian ladybird (Rodolia cardinalis) has survived and spread, while suppressing the cottony cushion scale on many native Galapagos plants, including the white mangrove, Acacias, and Scalesia. However, there are several plant species still being affected by the cottony cushion scale, and further study is required to determine why the mariquita is not effective on these host plants. In addition to being effective, the project has been safe, as no evidence from field observations or the large cage studies was found of attack by R. cardinalis on non-target insects.
