“…), which was present between 3% and 15% as cover in plots outside the Tamarix canopy, plant species were undesirable weedy species such as Palmer amaranth (Amaranthus palmeri S. Watson), S. elaeagnifolium, and S. tragus. Compared with the increase in native plants noted by Sher et al (2018), the overall lack of positive response by understory plants at our site is likely because the dry site is not hydraulically connected to the Rio Grande or Caballo Reservoir (currently at a historical low level) and did not experience any inundation during the entire experiment. A comprehensive study by González et al (2017) indicated that native vegetation recovery is dependent on restoration of fluvial processes.…”

“…Furthermore, the lack of treatment difference is not surprising given the time required for plant communities to respond to vegetation treatments. For example, Sher et al (2018) demonstrated that after Tamarix removal, native plants increased by year 2 and exotic plant cover did not increase until year 4. There was a change in plant species presence and abundance from pretreatment in spring 2016 (dry season) to ∼15 mo posttreatment in August 2017 (monsoon season), but this was based on precipitation, not treatment.…”

“…was investigated by Drus et al (2014), who concluded that integrating herbivory and fire provided a synergistic effect by depleting greater carbohydrate storages, particularly starch, resulting in higher Tamarix mortality compared with unburned treatments. Sher et al (2018) investigated management via lowdisturbance mechanical or chemical treatment integrated with Diorhabda spp. and documented that the change in relative cover of native understory plants was negatively correlated with change in Tamarix cover, and there was a greater positive change in native species cover at sites with integrated management.…”

Invasive shrubs like Tamarix spp. are ecological and economic threats in the U.S. Southwest and West, as they displace native vegetation and require innovative management approaches. Tamarix control typically consists of chemical and mechanical removal, but these methods may have negative ecological and economic impacts. Tamarisk leaf beetles (Diorhabda spp.) released for biocontrol are becoming increasingly established within Western river systems and can provide additional control. Previous Diorhabda research studied integration of beetle herbivory with fire and with mechanical management methods and herbicide application (e.g., cut stump), but little research has been conducted on integration with mowing and foliar herbicide application, which cause minimal soil disturbance. At Caballo Reservoir in southern New Mexico, we addressed the question: “How does Tamarix respond to chemical and mechanical control when Diorhabda is well established at a site?” A field experiment was conducted by integrating mowing and foliar imazapyr herbicide at standard (3.6 g ae L−1 [0.75% v/v] and low (1.2 g ae L−1 [0.25% v/v]) rates with herbivory. Treatments were replicated five times at two sites—a dry site and a seasonally flooded site. Beetles and larvae were counted and green foliage was measured over 2 yr. Mowing and full herbicide rates reduced green foliage and limited regrowth compared with low herbicide rate and beetles alone. Integrating conventional management such as mowing and herbicide with biocontrol could improve Tamarix management by providing stresses in addition to herbivory alone.

“…There are several techniques for the control and removal of invasive species that can be applied on a case-by-case basis, and there is a demand among restoration practitioners for a decision support tool to choose the best plant control methods (Sher et al, 2018). Management of invasive alien plants may or may not involve a combination of mechanical, chemical and biological control methods.…”

There are several techniques for the control and removal of invasive species that can be applied, and there is a demand among restoration practitioners for plant control methods. This study compared two methods for the control of jackfruit tree: mechanical method of trunk girdling and chemical method of herbicide injection into the trunk. It was evaluated both methods in terms of effectiveness in 10 plots (80 × 80 m). For the chemical method, triclopyr in concentrations of 2%, 6% and 8% was used. The progress of treatments was evaluated accordingly for the phytosanitary conditions. Method of trunk girdling proved to be ineffective and it had a low mortality rate (12%). The proportion of dead trees by chemical treatment was 100%. The results showed that chemical control of jackfruit trees was much faster and more effective.

“…Most studies of hurricane effects on invasive plants have utilized examples where biological control is absent [3,16]. However, the use of biological control, using natural enemies to target and control invading plant species, is now integrated with several integrated plant management strategies [2,22,27]. In general, herbicidal and biological control methods are different in the sense that the former method usually requires repeated treatment of the invasive plants [1,8,13] while the latter is generally capable of being self-sustained on the targeted invasive plant species and may require only a single treatment [30].…”

Understanding the effects of hurricanes and other large storms on ecological communities and the post-event recovery in these communities can guide management and ecosystem restoration. This is particularly important for communities impacted by invasive species, as the hurricane may affect control efforts. Here we consider the effect of a hurricane on tree communities in southern Florida that has been invaded by Melaleuca quinquevervia (melaleuca), an invasive Australian tree. Biological control agents were introduced starting in the 1990s and are reducing melaleuca in habitats where they are established. We used size-structured matrix modeling as a tool to project the continued possible additional effects of a hurricane on a pure stand of melaleuca that already had some level of biological control. The model results indicate that biological control could suppress or eliminate melaleuca within decades. A hurricane that does severe damage to the stand may accelerate the trend toward
