Missouri Ozark woodlands are a unique but imperiled ecosystem type because of fragmentation, lack of proper management and a changing climate. Management, restoration and conservation of Ozark woodlands is a conservation priority. The ecosystem services provided by Ozark woodlands include carbon and nutrient sequestration via primary productivity. We have assessed over- and mid-story leaf production, collecting leaves in baskets every fall, in a 1,200ha conservation area in SW Missouri since 2000. Leaf production data from 2000 to 2020 was compared among sites; control, burned (periodically burned) and reference (continuously burned). Average oak leaf production was high in the burned while the other leaf production was high in control. Sapling density of oak was found high in the burned site compared to the other sites. We applied the regression among productivity, temperature, and precipitation. Reference site showed a statistical significance with the precipitation but not with the temperature. While other sites did not show any statistical significance with the precipitation. No statistically significance difference in effect was observed between the productivity and temperature on any sites. March-June, March-May and June-August precipitation showed a statistically significant difference with the productivity while the other average precipitation and temperature showed no statistical significance.
