ECOLOGICAL MONITORING

LONG-TERM WOODLAND MONITORING

Overview

Tree, vegetation, soil and faunal data are collected seasonally across Greenacres’ woodlands to understand the forest ecosystems and how they may be changing over time. Long-term monitoring provides us with baseline data about the flora and fauna living in our woodlands. Across sites, we have an understanding of the types of spring wildflowers growing, the diversity of tree species and the impact invasive species are having in our forests. As we implement management strategies in these woodlands, ecological monitoring is used to assess their impact and inform future management decisions.

Project Overview

In 2018, we started ecological monitoring to gather baseline data on our woodlands. Simultaneously, we were aggressively removing the invasive Amur honeysuckle from our property and studied vegetation shifts resulting from its removal. Our studies weren’t limited to plants; we began faunal surveys that included macroinvertebrates, amphibians, and reptiles, like salamanders, to gauge forest health. Our project includes understanding the diverse tree canopies and the mix of native and invasive species in the understory. This allows us to monitor threats and evaluate the impacts of our management choices.

Our approach

Fifty meter transects are set up at each monitoring site. Transects are monitored 3 times a year for 2 years, and then rested for 2 years. Along each transect, 4 plots (4 m2) are sampled for herbaceous vegetation and seedlings. Soil data is collected at the center of each transect. The amount of sunlight coming through the canopy is also measured along each transect. Tree data are collected along the transect and used to calculate density and basal area. Tree sapling and snag data are also collected. Six pitfall traps are located along each transect and macroinvertebrate sampling occurs annually. Circles (radius 7.5 m) at both ends of transects are surveyed for reptiles and amphibians in spring, summer and fall.

Luke is the Research Assistant at Greenacres. He graduated from the University of Cincinnati in 2022 with a B.S. in Environmental Studies and a Geographic Information Systems (GIS) certificate. While in school, he spent a year as Greenacres’ research intern before being hired full-time. Luke coordinates ecological monitoring and field experiments at Greenacres. He also specializes in creating and managing Greenacres’ geographic data. Those data and maps are then used to inform research projects and assist with land management goals.
