New Publication on Emerging Frameworks for Mitigating Woody Plant Encroachment
May 2, 2018 by shishir.basant
A new paper commenting on the emerging frameworks for mitigating Woody Plant Encroachment (WPE) was just published in the journal ‘Current Opinion in Environmental Sustainability’. The focus of the paper is understanding savannas (woody plant encroachment) under the Alternative Stable State Theory (ASST). As the authors revisit some of key conceptual models of ASST laid down by John Anderies and Marten Scheffer, the paper strongly emphasizes on acknowledging pyric herbivory and fire together as stabilizing forces for sustaining a grassland. The observations regarding shifts in the two feedback cycles sustaining a grassland have been summarized through illustrations which also bring to surface the point that such changes related to a woodland state are always realized with a time-lag and that triggers for such changes may lie well in the past.
As we still remain from fully understanding drivers of woody encroachment and reconcile these changes in ‘endogenous’ factors along with changes in the ‘exogenous’ factors – this article lays forth a strong argument for considering the role of pyric-herbivory and fire in not just understanding but also manage woody plant encroachment.
The authors on the paper include Dr. Brad Wilcox, Dr. Andrew Birt, Dr. Sam Fuhlendorf and Dr. Steven Archer. This work came together as a result of their collaborative effort on the NSF-CHNS project – “Woody Plant Encroachment in the Southern Great Plains”.

Our most recent paper talks about soil infiltration and erosion in Caatinga – a dry tropical forest biome situated in North East Brazil. Results from rainfall simulations over forests of different ages were compared for infiltration and erosion. In addition, beerkan methods was used to estimate infiltration curves and hydraulic conductivity for different ages and vegetation cover. Ksat determined from lab and beerkan methods were found to be consistently increasing with time since it was left for recovery or regrowth of forest.
Field work for this study was carried out over the summer of 2015 by Pedro Leite, Brad Wilcox and their colleagues Eduardo Santos, Eduardo Souza and Rafael Oliveira at Federal Rural University of Pernambuco in Recife (UFRPE, Brazil). The study is part of an ongoing collaborative project with UFRPE and Wilcox lab at Texas A&M.

Brad Wilcox awarded Sid Kyle Endowed Professor
April 1, 2017 by wilcoxlab
Earlier this March, Dr. Brad Wilcox was awarded the Sid Kyle Endowed Professor in Arid and Semi-Arid ecohydrology. On the same occasion, Dr. Boutton was also awarded the Sid Kyle Endowed Chair in Arid and Semi-arid ecohydrology for Biogeochemistry. This award will bring funds which will provide more impetus to Dr. Wilcox’s lab’s effort in understanding the ecohydrology of savannas in Texas, Oklahoma, Mexico and North-Eastern Brazil. With new funds available, the lab will be looking to support undergraduate research work at the range area – a research site owned by the department of Ecosystem Science and Management near College Station airport. The site is representative of a post-oak savannah and will add another dimension to the ongoing work in Southern US plains and Northeast Brazil.
Streamflows do not increase by killing Salt Cedar: Study on Pecos River
October 6, 2015 by wilcoxlab
A new study published in Water Resources Research has found out that killing or removal of Salt Cedar,a species introduced in U.S. in early 1800s, from riparian regions do not increase stream flows. This is a groundbreaking result as it challenges the existing assumption that Salt Cedar reduce stream flows because of increased transpiration rates.
Dr. Alyson McDonald, who is the lead author on the study, is a Texas A&M AgriLife Extension Service range specialist at Fort Stockton and is also a former Phd student of Dr. Wilcox.
The team of scientists who worked on this study include Dr. Alyson McDonald, Dr. Bradford Wilcox and Dr. Georgianne Moore, department of ecosystem science and management, Texas A&M University, College Station; Dr. Charles Hart, Dow AgroSciences, Stephenville; Dr. Zhuping Sheng, AgriLife Research, El Paso; and Dr. Keith Owens, department of natural resource ecology and management, Oklahoma State University, Stillwater.
