Grasshoppers are in full force this year! Has that delayed your foliar herbicide applications on mesquite? If herbicide application success is dependent on optimal uptake through healthy, mature leaves, then what effect can varying defoliation rates have on herbicide efficacy of clopyralid, triclopyr, and clopyralid+triclopyr applications?

Ever wonder the effectiveness of herbicides on honey mesquite during drought? Well, researchers from our department were wondering the same thing and studied how drought effects herbicide efficacy in herbaceous and woody plants. There were chamber studies conducted to evaluate the influence of water stress and triclopyr on the absorption and translocation of clopyralid in greenhouse-grown honey mesquite. Clopyralid is an auxin-type herbicide highly effective at honey mesquite control. It is often used alone or in combinations with other active ingredients to form common honey mesquite foliar-applied herbicides like Sonora™ and Sendero™.

A Fire danger index (FDI) is a measure that is used to assess the risk and severity of a fire. It relies on the combination of weather and fuel conditions. These FDI’s have been used to help predict and manage the risk of wildfires. Even with these tools, there is still uncertainty in predicting the likelihood of fire ignition or the potential size the fire can get.
In the study below, four of the FDI’s were analyzed and had a sensitivity analysis performed on them to determine the most important drivers. The sensitivity analysis determined that daily minimum relative humidity, precipitation, and wind speed were the most important driving factors in future wildfire dangers, including length of a wildfire season.
The study also included a regional climate model simulation to derive FDI’s for current and future climate conditions. The results from this simulation suggested that an overall increase in fire potential and a prolonged wildfire season is expected in our future Texas climate. Enhanced fire frequency and fire season length is expected to occur in Spring and Summer throughout the Southern Great Plains.
By 2050, the number of days with wildfire danger in Texas could increase by as many as 40 days per year with high heat and dry periods significantly lengthening the wildfire season.

Above average precipitation during the growing season, spurring on massive amounts of grass growth, followed by significant drought, resulting in an intense wildfire season. All within a single year. It’s absolute whiplash! Sound familiar? Researchers recently examined the role of whiplash events where preceding precipitation produce massive fuel for wildfires in a short period of time using 2017-2018 in Texas and Oklahoma as a case study. While studies like these have been done in California, there have been limited studies like this across the Southern Great Plains. This study was the first time that the relationship among precipitation, vegetation, and wildfires have been looked at collectively across the Southern Great Plains!
Hurricane season is coming fast and furious! NOAA is predicting an above-normal hurricane season, forecasting 17 – 25 named storms (winds higher than 39 mph), 8-13 hurricanes (winds of 74 mph or higher) and 4-7 major hurricanes (Cats 3, 4, or 5 with winds of 111 mph or higher). The sea-surface temperatures are already exceeding last year’s temperatures. The figure above shows the differences in temperatures from this year and previous years. With all this in mind, NOAA is predicting an 85% above-normal season. The season stretches from June 1st – November 30th.
Did you know that there are more than 500,000 miles of oil and gas rights-of-ways in Texas alone? There has been limited information available to evaluate the difference in restoring disturbed lands to native states versus the more traditional use of non-native seeds. Being able to understand the difference along with the ecosystem impacts and the social benefits could create a positive case for vegetation restoration by the oil and gas industry.

As the climate is changing so is the frequency and severity of short-term drought events. A new study by Dr. Bill Rogers and others (the study has over 169 authors from around the world!) showed that while drought has intensified, the effects on the functioning ecosystem remain largely unresolved and unrecovered. This is due to the differences in variations of drought and differences in ecosystems that potentially mediate drought impacts. This fascinating new research from Dr. Rogers and team used a coordinated distributed experiment to quantify the impact of short-term drought on grassland and shrubland ecosystems from across the world.

West Texas:
Strong demand for quality tracts continues to hold up prices in the region. At $2,410 per acre, prices rose 8.02 percent YOY. Tract size has also decreased from highs in 2021 and 2022, coming in at 385 acres this quarter, 10.65 percent below one year ago. Annualized sales volume declined 50.97 percent to 431 sales. Total dollar volume at $155.54 million decreased by 72.39 percent. At 64,540 acres, though a slight increase from last quarter, total acreage declined 74.44 percent YOY. Fourth quarter only sales volume fell 26.09 percent below that of fourth quarter 2022, a much less drastic drop compared to YOY.

The Nebraska Prescribed Fire Council has published its second issue of Prescribed Fire Lessons Learned! The Nebraska Prescribed Fire Council takes submissions from practitioners on lessons learned from prescribed fires to assist producers, landowners, PBAs, and other prescribed fire professionals to keep improving season after season. This forum has been invaluable in learning from one another in hopes that mistakes or judgment calls turn into valuable lessons for all of us building and contributing to prescribed fire culture. Below are some highlights from this issue.
This is likely no surprise to you, but drought persists across the western U.S. and is intensifying in some areas. No geographic area is immune to the potential of drought at any given time. The U.S. Drought Monitor provides a weekly drought assessment, and it plays an important role in USDA programs that help farmers and ranchers recover from drought.
