Abstract
The significant loss of mature ash trees at Twin Lakes Bible Camp (TLBC) has motivated efforts to restore green spaces by planting replacement trees. In summer 2024, 32 trees representing eight unique species were planted, and their overall health and site suitability were evaluated to inform future replanting efforts in summer 2025. The five soil series present at TLBC (Canisteo, Clarion, Webster, Okoboki, and Nicollet) were evaluated by soil chemistry testing through x-ray fluorescence spectrometry. This study presents site-specific data of tree growth measurements, visual health assessments, and soil compatibility analyses to identify practical recommendations for improving restoration success. The reference guide designed in this study is the primary tool for TLBC staff in future planting, comparing soil series with recommended tree species options.
