Climate change threatens the Great Plains, but bison may hold a key to resilience
“The 8,600-acre Konza Prairie Biological Station where Kansas State conducts its bison research lies in the Flint Hills, North America’s biggest remaining stretch of tallgrass prairie.
Once one of North America’s major ecosystems — covering large swaths of the Great Plains from what is today central Texas to south-central Canada — settlers and their descendants destroyed more than 95% of the continent’s tallgrass prairie for cropland and other development. Tallgrass in the Flint Hills escaped the plow only because the region’s shallow soil and rocky layers made farming less practicable there…
Bison act and eat differently than cattle do, though biologists say not all the differences are clear yet. Few studies compare these two bovine herbivores side by side.
Still, a few differences jump out. The bigger species not only eats more grass, it also spends less time along streams than cattle do and more time on hilltops…”
Cattle may not boost plant biodiversity on the prairie as much as bison do, but The Nature Conservancy thinks it’s possible to manage them in ways that support healthier grassland.
They are working with a Flint Hills cattle rancher near Strong City in Kansas, along with Kansas State scientists, to see how fitting a herd with GPS collars might help….
Nature-based solutions funding database
National Wildlife Federation has created an interactive database for communities interested in pursuing federal funding and/or technical assistance for nature-based solutions. You can use their filters to search for nature-based solutions funding and technical assistance resources that fit your needs. For additional information on search filters, see their Glossary page.
Alley cropping case studies in Appalachia
The Natural Resource Conservation Service (NRCS) describes alley cropping as having several conservation purposes, including reducing surface water runoff and erosion, improving soil health, altering subsurface water quantity or water table depths, enhancing wildlife and beneficial insect habitat, increasing crop diversity, and increasing carbon storage.
Much like agrivoltaics with crops and/or cattle, the combined farming practice can increase overall yields and benefits. Plus, funding may be available. The case study focuses on Appalachia but could be emulated elsewhere.
New York City’s greenery absorbs a surprising amount of its carbon emissions
A study of vegetation across New York City and some densely populated adjoining areas has found that on many summer days, photosynthesis by trees and grasses absorbs all the carbon emissions produced by cars, trucks and buses, and then some. The surprising result, based on new hyper-local vegetation maps, points to the underappreciated importance of urban greenery in the carbon cycle…
Ancient grasslands guide ambitious goals in grassland restoration
Grasslands, which constitute almost 40% of the terrestrial biosphere, provide habitat for a great diversity of animals and plants and contribute to the livelihoods of more than 1 billion people worldwide. Whereas the destruction and degradation of grasslands can occur rapidly, recent work indicates that complete recovery of biodiversity and essential functions occurs slowly or not at all. Grassland restoration—interventions to speed or guide this recovery—has received less attention than restoration of forested ecosystems, often due to the prevailing assumption that grasslands are recently formed habitats that can reassemble quickly. Viewing grassland restoration as long-term assembly toward old-growth endpoints, with appreciation of feedbacks and threshold shifts, will be crucial for recognizing when and how restoration can guide recovery of this globally important ecosystem.
New England’s climate imperative: our forests as a natural climate solution
In this study, five pathways are developed and assessed that could increase the climate mitigation potential of New England’s forests:
- Avoided deforestation
- Wildland reserves
- Improved forest management
- Mass timber construction
- Urban and suburban forests
Study shows worsening wildfire smoke is unraveling decades of air quality gains
Wildfire smoke now exposes millions of Americans each year to dangerous levels of fine particulate matter, lofting enough soot across parts of the West in recent years to erase much of the air quality gains made over the last two decades.
In late September, Stanford University researchers published this study that found residents of Western states were exposed to a 27-fold increase of harmful particulate matter pollution, known as PM2.5, between 2006 and 2020 as wildfires intensified.
The world’s forests do more than just store carbon, new research finds
Researchers from the U.S. and Colombia found that, overall, forests keep the planet at least half of a degree Celsius cooler when biophysical effects — from chemical compounds to turbulence and the reflection of light — are combined with carbon dioxide…
Keeping cattle on the move and carbon in the soil
The Obrechts stand at the forefront of an emerging collaboration between ranchers, conservation groups, and governmental agencies that aims to protect, restore, and revitalize the United States and Canada’s prairies — or what’s left of them…
Researchers estimate that grasslands could contain as much as 30 percent of the carbon stored in the Earth’s soil. Plowing them in order to plant crops releases large amounts of that carbon into the atmosphere…
Two groups want to put focus on carbon credits from urban forests
National Public Radio discusses urban carbon credit work. Lookout Mountain Conservancy is participating in this effort.
“We know trees can help address climate change. A forest sucks carbon dioxide from the atmosphere. That can be sold as a carbon credit to companies looking to offset their environmental impact. But the way those credits are calculated has long been scrutinized. And two groups want to put focus on urban forests. Bellamy Pailthorp of KNKX explains…”
