“Plant Species and Hydrology as Controls on Constructed Wetland Methane Fluxes” with Karla Jarecke and Dr. Terry Loecke Wetlands are important ecosystems that provide many important services, such as assisting in water quality, flood control, erosion protection, carbon removal and storage, and biodiversity. Hydrology is the study of water, specifically in how it moves throughout the landscape. Combine them with the conundrum of methane production in wetland plant species, and you’ve got the makings of a fascinating research project. Specifically, Karla Jarecke and Terry Loecke’s project. By testing methane production in two common wetland species under both lab and field conditions, they worked to answer important questions about not only how methane production, hydrology, and wetland species work together, but also how we can better plan for the creation and care of constructed wetlands. Listen in to learn about:  The lifecycle of methane within wetlands The different kinds of flora and fauna that live in them How a parks program turned a would-be landfill into a new wetland How field and lab conditions can differ, both in logistics and results  If you would like more information about this topic, this episode’s paper is available here: https://doi.org/10.2136/sssaj2018.11.0421  It will be freely available from 15 Nov. to 29 Nov., 2019.

Methane, Hydrology, and Constructed Wetlands with Karla Jarecke and Dr. Terry Loecke

One kilometer. Or roughly ten football fields. That’s the extent of the area over which Karla Jarecke can feasibly navigate her way through the trailless HJ Andrews Experimental forest to collect the data she needs in a typical day of field work. Experimental watersheds like the HJ Andrews forest (link here) were established initially to understand how clear-cutting influenced forest drainage. This was during the time when timber-take was increasing and we still had little understanding on its ecosystem effects. Karla’s work is also forward-thinking, but less on the lines of what will happen to drainage when trees are removed and more focused on understanding the availability of water for trees to use now and in the future. She wants to know what influence topography has on plant water availability in mountainous landscapes. Karla explains that there have been long-standing assumptions surrounding elevation gradients and their control on water availability in a forest system. This understanding has led to modeling tools currently used to extrapolate soil moisture across a landscape. But so far, her data show huge variability on surprisingly small scales that cannot be explained by gradient alone. This indicates that there are other controls on the spatial availability of soil moisture in such mountainous terrain. This information builds on the incredible sixty-year data set that has been collected on soil moisture within HJ Andrews, but with a new perspective.
