I have been exploring Oklahoma’s biodiversity for over 25 years. Arriving at the University of Oklahoma to study grasslands as a grad student, I soon found out that there was much more to Oklahoma than prairie! Working at the Oklahoma Biological Survey for the past 20 years, I have studied all 12 of the state’s ecoregions – surveying endangered birds, looking for invasive aquatic plants, measuring trees of the Ozark forests, collecting data on mesquite grasslands, restoring biodiversity to degraded systems, and more. I have managed the Oklahoma Natural Areas Registry Program, organized outreach and science communication projects, and am currently the Oklahoma Natural Heritage Program Coordinator.
For my book tour finale, I am taking an ambitious journey – across the state, from high point to low point, on my bike. That is, from the tri-state marker, on the western edge of the Panhandle, down to the lowlands of McCurtain County on the border with Arkansas. I don’t intend to take the…

Back in May, I took a quick trip to the Oklahoma Panhandle to see a couple rare species populations, but I also squeezed in a short bike ride from the tri-state marker to Black Mesa State Park. I love riding my bike at a “curious pace” so that I can easily stop to admire the…

As some of you know, I am a cyclist and participate in events across the state. MidSouth is an event in Stillwater that attracts thousands of people from across the country, and internationally. They want to educate people about the areas they are visiting and riding through. In the past, have produced a booklets for…
Happy Autumnal Equinox! Today marks the day when the sun is directly over the equator and the northern hemisphere will have less direct sunlight until the spring equinox. Personally, I am relieved to be tilted away from the sun for the next two seasons. The growing season is winding down, but we still have lots…
Over the past couple weeks I have been messaging with the marketing department of OU Press about a couple different things book things. First, the cover mock ups – imagine my delighted squeal! Seeing these, made by other people, makes the book seem more real. I think both options are lovely. I asked co-workers, family,…
This is most appropriate because I am headed to the International Monarch Science Symposium hosted by Monarch Watch in Lawrence, KS this week. In my lab, we are growing two late summer/fall thriving milkweed species – the native Honeyvine (Cynanchum laeve) and the non-native tropical milkweed (Asclepias curassavica). Students in my lab will be counting…
This week, I had the privilege of doing field work at a tallgrass prairie remnant that is one of the best examples of grassland I have seen in southcentral Oklahoma. On the grounds of the Choctaw Cultural Center in Bryan County, this prairie has a diversity of native grasses and wildflowers, few exotic invasive species,…
Last fall I hosted a few field notebook/nature journal workshops and attendees were interested in creating a club. I am sorry for the long delay, but I am ready to host nature journal meet up as an official meeting of the Cross Timbers Nature Journal Club! We have a converted meeting space at our office…
In Oklahoma, wetlands occur in all of our ecoregions. These images are from a variety of wetlands in southeastern Oklahoma, which has the greatest number of wetlands in the state – forming in response to the abundance of precipitation, flat terrain, and high water table. In the early 1900s, wetland protection became a priority for…
Did you know that July is National Bison Month? And the bison is Oklahoma’s state animal. The largest North American land mammal is the American bison (Bison bison), aka American buffalo. These enormous animals have had an important impact on the ecology and habitats of the Great Plains. Through grazing, seed dispersal, trampling, and wallowing,…
