Ecological and Physical Description
Deep alluvial deposits underlain by limestone. Wlllow oak, water oak, dlamondleaf (laurel) oak (Ouercus phellos, Q nigra, Q laurlifolia) alluvial
floodplain forest.
The entire area is forested, and there has been no cutting in the last sixty years.
The wettest period occurs in the spring, and the driest time is in the fall. The highest total precipitation recorded from 1945 to 1975 was 73.4 inches (186.4 cm) in 1957 and the lowest was 30.5 inches (77.5 cm) recorded in 1956.
The nearest weather station is at Idabel, Oklahoma, approximately 20 miles (32 km) west of the RNA.
In the Tiak RNA, alluvial deposits overlie the bedrock. Bedrock in southern Mc Curtin County consists of sedimentary rocks of the Comanche and Gulf series of the Cretaceous system. The soil of the proposed Tiak RNA belongs to the Guyton series. The Guyton series consists of deep, nearly level, poorly drained soils on flood plains and terraces.
The Tiak RNA is in a relatively flat bottomland hardwood forest that is occasionally flooded. Watershed values of the area are high, since rainfall in the area is relatively high and forested wetlands absorb water and release it slowly.
