Who We Are
The LTAR Network is a growing group of researchers focused on finding solutions that maintain or increase agricultural productivity, environmental quality, and people well-being in spite of pressures such as climate change. Read more
Our Research Approach
The LTAR network combines strategic research projects with common measurements on multiple agroecosystems (croplands, rangelands, and pasturelands) and develops new technologies to address local and national challenges and opportunities.

A new study suggests that targeted livestock grazing can be an effective and affordable way to manage cheatgrass in the western Great Plains of the U.S. when timed to coincide with cheatgrass growth rather than solely based on the time of year. https://t.co/8kQl7BpBIc pic.twitter.com/eMukj6CFAa

Adaptive grazing management can help ranchers and rangeland managers adapt to climate change. By anticipating and responding to changing conditions, we can ensure healthy, productive rangelands and support thriving livestock-based economies.https://t.co/lh12rcOuNz@USDA_ARS pic.twitter.com/aNY2g0lTmB

See how ARS scientists in Boise, ID, are employing prescribed cattle grazing as a management tool. This promotes ecological restoration and wildfire protection of western rangelands overrun by invasive and flammable grasses, like cheatgrass and medusahead. https://t.co/KPkcJTnRap pic.twitter.com/GzHrEtQA2E

ABOUT LTAR
The USDA Agricultural Research Service (ARS) Long-Term Agroecosystem Research network consists of 18 Federal and university agricultural research sites with an average of over 50 years of history. The goal of this research network is to ensure sustained crop and livestock production and ecosystem services from agroecosystems, and to forecast and verify the effects of environmental trends, public policies, and emerging technologies.
