EXST7015 Daily Design 9 Carefully read the description of the experiment below. Be prepared to answer the questions that follow the design description as a class quiz. Forestry production is limited in the Bolivian high plains. High altitude, low rainfall, and a variable climate all contribute to cause extremely high mortality rates among tree species. The purpose of this study was to examine whether microcatchment systems can improve tree establishment rates in the Bolivian high plains. Five different types of microcatchment systems were used: (1) Control. no microcatchment system (trees placed directly into the ground without any protection), (2) pit planting method (a simple 30-cm hole dug in the ground with one hole per seedling), (3) trench system (dug to a depth of 30 cm along a contour), (4) widened trench basin (trench depth still 30 cm and laid out along the contour but wider, approximately 60 cm) (5) slanted trench system (similar to number 4 with an additional trench dug 30 cm deeper inside to provide further water collection and protection). The five microcatchment systems were planted in ten groupings along on a hillside with groupings
