Honey mesquite varies widely in its response to herbicides. Previous research demonstrates most effective treatments have occurred about 50 to 90 days after the first leaves appear in the spring when they are fully formed and dark green (Bovey and Mayeux, Jr. 1981; Jacoby and Meyers 1983; Meyer et al., 1986). More recently, triclopyr has been found to be effective for control of honey mesquite (Bovey and Mayeux, Jr. 1981; Jacoby et al., 1981; Jacoby and Meadors 1983). Also, clopyralid has been found to be highly effective for controlling honey mesquite (Bovey and Mayeux, Jr. 1981; Jacoby et al., 1981).
North American Grasslands Conservation Council – Upcoming Bill
Did you know that grasslands provide vital habitat for a multitude of species which represent the lifeblood of local and regional economies?? That the maintenance of health populations of grasslands species and working lands are critical for rural economies? That grassland and rangeland ecosystems provide essential and significant habitat for mammals, pollinators, reptiles, and other wildlife? Roughly 358,000,000 acres or 85% of the United States is privately owned and serves as an important habitat for 29 grassland bird species!

Herbicide Efficacy Following Defoliation on Honey Mesquite
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?

Drought and Triclopyr on Clopyralid Efficacy in Honey Mesquite
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™.

Future Wildfire Seasons: Hotter, Dryer, and Longer
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.

The Wildfire Impacts of the 2017-2018 Precipitation Whiplash Event across the Southern Great Plains
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!
Texas + Water – June Update
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.
What is the Value of Native Vegetation Restoration on Oil & Gas Rights-of-Way?
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.

Extreme Drought Impacts have been Underestimated in Grasslands and Shrublands Globally
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.

2023 Rural Land Value Trends Report
Check out the 2023 Rural Land Value Trends Report from Texas Agriculture Law Blog by Tiffany Lashmet! https://agrilife.org/texasaglaw/2024/05/06/2023-rural-land-value-trends-report-is-here/
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.

- In discussions with an attorney in San Angelo, he stated that he had worked on 10 to 15 wind and solar leases in 2023, with 8 to 10 of those signed. Several of the companies decided they were no longer interested before the lease was signed.
- According to the attorney, this was due to a number of factors including poor due diligence on the part of the company or ERCOT West not having enough transmission lines. These wind leases come in blocks where the attorney may represent one to a dozen landowners at a time.
- As mentioned in the 2022 discussion, a solar farm in San Angelo area was expanding. This expansion has been completed from one to two sections. There has not been any construction in the immediate San Angelo area since 2022 of any new solar farms. This could be a result of the increased cost due to higher interest rates, cost of materials and construction costs.
- Purchases by developers dropped significantly in 2023. This is due primarily to the increased interest rates and the fact the end users for these properties are no longer in the market due to the higher interest rates.
- There continues to be an increase in residential development in the immediate area of the larger trade areas, specifically Wichita Falls, Abilene and San Angelo. It appears that residential buyers continue to move to areas with smaller schools, which are considered to be above average for educational opportunities.
