Understanding the similarities and differences between primary and secondary forests is important because secondary forests are becoming a prominent feature in the landscape, yet we know little about their conservation value and their potential for replacing primary forests. The aim of this study is to better understand if predation rates along a shared edge of primary and secondary forests differ, and if distance from edge affects predation rate. We predict that, as distance increases from forest transition zone between primary and secondary forests, predation rates will increase. Using model caterpillars and 2 types of eggs, predation rates were assessed by placing models or eggs on a 100-meter transect stretching into both primary and secondary forests. Results concluded that egg type, forest type, and a combination of egg type and forest type are not significant in affecting predation rate. However, distance from the transition edge of primary and secondary forests was significant in predation rates. Exploring predation rates at the transition edge of primary and secondary forests, we may be able to predict and better understand secondary forest conservation value in comparison to primary forests in order to develop beneficial management solutions.
