Index insurance for pro-poor conservation of hornbills in Thailand

This study explores the potential of index insurance as a mechanism to finance community-based biodiversity conservation in areas where a strong correlation exists between natural disaster risk, keystone species populations, and the well-being of the local population. We illustrate this potential using the case of hornbill conservation in the Budo-Sungai Padi rainforests of southern Thailand, using 16-y hornbill reproduction data and 5-y household expenditures data reflecting local economic well-being. We show that severe windstorms cause both lower household expenditures and critical nest tree losses that directly constrain nesting capacity and so reduce the number of hornbill chicks recruited in the following breeding season. Forest residents' coping strategies further disturb hornbills and their forest habitats, compounding windstorms' adverse effects on hornbills' recruitment in the following year. The strong statistical relationship between wind speed and both hornbill nest tree losses and household expenditures opens up an opportunity to design wind-based index insurance contracts that could both enhance hornbill conservation and support disaster-affected households in the region. We demonstrate how such contracts could be written and operationalized and then use simulations to show the significant promise of unique insurance-based approaches to address weather-related risk that threatens both biodiversity and poor populations

Long-term monitoring of breeding successes of Great Hornbill (Buceros bicornis) and Rhinoceros Hornbill (Buceros rhinoceros) using artificial nest boxes in Budo-Su-Ngai Padi National Park, Thailand

Nest boxes are a conservation tool for increasing the availability of nests. The efficacy of nest boxes can be assessed by examining the breeding parameters of birds in nest boxes to see whether data are comparable with tree cavities. The hornbill artificial nest research was conducted in Budo-Su-Ngai Padi National Park, Thailand since 2003. This project aims to increase the breeding propensity of two large species of hornbills; the Great Hornbill (Buceros bicornis) and the Rhinoceros Hornbill (Buceros rhinoceros) that coexist in the study area, by utilizing nest boxes. The nest boxes were constructed from fiber-reinforced plastic. There were two designs; small nest box: 50 x 49 cm at base and 95 cm height, and large: 65 x 70 cm at base and 95 cm height. Twenty nest boxes were installed between 2004 and 2006. These nest boxes were monitored from 2004 to 2021. The study results indicated that the proportion of nest occupancy of Great Hornbill breeding in natural nests was higher than nest boxes: 48.9% and 31.4%, respectively (the two binomial proportions test gives: Zc= 4.01, P < 0.0006 < α = 0.05). The results also showed that the Great Hornbill prefers to select a large nest box than a small one: 37.3% and 17.3%, respectively (the two binomial proportions test gives: Zc = 3.4, P < 0.00068 < α = 0.05). Eight nest boxes so far have been utilized by hornbills: six by Great Hornbill with 58 nesting successes and two by Rhinoceros Hornbill with 1 nesting success. The average life cycle of the fiberglass nest box is about 11.38±4.23 SD years. The study results suggest that reproduction parameters of hornbills in nest boxes are different from natural cavities in many aspects. Our two target species do not equally benefit from nest boxes
