How to control mesquite?
Controlling mesquite is a challenging task. One often-used method is mechanical control. This can be effective with high mortality rates if stems are cut at least 20 cm underground. Another method is through the application of herbicides, done on an individual plant basis. Basal application is effective to mesquite of all sizes, while foliar application is best for plants smaller than 1.5 m. Another physical option for control is through fires. Some species of mesquite are fire-sensitive, while others are fire-tolerant. For those that are fire-sensitive, this method can be highly effective, but those that are fire-tolerant require hot and intense fires to be effective. In Australia, scientists are trying biological control methods. They have introduced multiple insects, but the most effective in causing high population level impact is the leaf-tying moth ( Evippe spp.). The most recommended method for managing Prosopis, both in native and introduced ranges, is by targeting large numbers of plants either through herbicide or physical removal. Also, research is being done on using satellite and aerial images to assess canopy cover and determine which ranges should be targeted.
Why is honey mesquite considered an invasive species?
Although Prosopis spp. are naturally occurring in these areas, these changes have resulted in their being able to successfully outcompete other native plants and they are now considered invasive species because they are able to take advantage of vulnerable ecosystems.
How does Prosopis spp. affect the ecosystem?
Their impacts on the invaded ecosystems include changes to hydrological, energy, and nutrient cycling, as well as consequences to biodiversity and primary production.
How did Prosopis spp. evolve?
Prosopis spp. have been in North America since the Pliocene era and their wood has been dated to 3300 yr BP. They are thought to have evolved with megafauna in the New World. The loss of North American megafauna at the end of the Pleistocene era gave way to one theory of how the Prosopis spp. were able to survive. One theory is that the loss of the megafauna allowed Prosopis spp. to use their fruit pods to attract other organisms to spread their seeds; then, with the introduction of livestock, they were able to spread into grasslands. Another is that Prosopis spp. had always been present in grasslands, but recurring fires had delayed plant and seed development before the emergence of livestock and grazing.
Why is Prosopis considered long lived?
Prosopis is considered long-lived because of the low mortality rate after the dicotyledonous stage and juveniles are also able to survive in conditions with low light and drought. The Cahuilla indigenous people of western North America were known to eat the seeds of mesquite.

How long do mesquite seeds live?
Many people believe that mesquite seeds live indefinitely in the soil, which enables the plant to reinfest areas for long periods after it has been controlled. It is true that mesquite seeds from stored herbarium samples have maintained germination levels of 60 percent after 50 years.
Where is mesquite found?
Mesquite is common across the southwestern United States at elevations of up to 4,500 feet. Its northern limit—southwestern Kansas, southeastern Colorado, New Mexico, southern Utah, and southern Nevada—is defined by cold. Mesquite grows well in many types of soil except deep sands and soils that remain wet for long periods.
How long does it take for mesquite seedlings to grow?
To survive, mesquite seedlings need light and soil cover, as well as soil moisture for at least 3 to 5 days after germination. Soil temperatures must be at least 77°F for the seedlings to establish; they grow fastest at soil temperatures of 80 to 90°F; and their growth slows above 95°.
How many stages of growth does a mesquite plant have?
Growth and development. Mesquite plants have three growth stages: Seedling: From seed germination until the establishment of the first true leaf. Juvenile: From the appearance of the first true leaf until the plant produces mature, woody xylem tissue. This stage is also often called the seedling stage.
What caused the increase in mesquite density?
Cattle drives in the 1880s are thought to be partially responsible for increased mesquite density within stands of mesquite. However, research near San Angelo in 1999 and 2000 suggests that the presence or absence of livestock does not affect the disappearance of mesquite seed.
What temperature does mesquite germinate?
For mesquite, maximum germination occurs when the temperature ranges from 80 to 85°F and when about 0.2 inch of soil covers the seed. Establishment is successful if the seeds germinate beneath a thin layer of soil or organic material or debris.
Why are mesquites fire resistant?
Adult mesquites are fire resistant because the bud zone is underground (Fig. 7), where it is protected, and the plants can resprout after the top has been removed. Reports of whole-plant mortality from fire are rare, occurring only in large trees with rat nests at the base.
How to tell if a mesquite tree is healthy?
Check for Problems. Check periodically for problems with your Mesquite tree. When inspecting your Mesquites, don't be alarmed is you see sap bleeding from the bark -- this is a sign of a healthy tree. If you notice the trunk splitting, this could be the result of the tree growing too fast and not a sign that it's dying.
When do mesquite trees start to produce new leaves?
Wait until late spring to check if the tree was just in its dormancy phase. Mesquite trees are deciduous and lose their leaves during winter then produce new ones in late spring. Walk around the tree to check for signs that new leaves are sprouting and that the tree is also producing creamy-white flowers. If by late May, your Mesquite tree is still bare, it is likely dying or already dead.
Why is my mesquite tree splitting?
Overwatering causes them to grower faster than normal, which causes an overly large crown and a weaker trunk. Watering a Mesquite less often and performing a heavy pruning is a remedy for the tree's tendency to split from growing too fast.
How to tell if a tree is dead?
A sure way of checking if a tree is dying, or already dead, is to check its bark. Make a small, shallow cut in the bark of the tree and open the cut to check in the inner skin portion of the bark. If the skin portion of the bark is green, the tree is alive and healthy; if the skin is turning brown, however, the tree is dying.
Can mesquite trees survive in the desert?
Found typically in the desert, they tolerate heat, sandy soil and drought. The only thing they don't tolera te is overwatering. Mesquite tree owners often mistake dormant trees as dead or dying, even though the trees are hard to kill.
Getting Acquainted with Mesquite
Adaptations to The Desert Environment
- From crown to root tips, mesquites have evolved a number of adaptations especially designed to help assure survival in the desert environment. Their thorns, sharply pointed and strong, challenge browsing by desert herbivores. (“They will not decay in the flesh or gristle as will prickly pear thorns,” Dobie said, “but will last longer than any flesh...
Mesquites as Botanical Enemies
- The mesquites’ encroachment into pasturelands and displacement of grasses has frustrated cattlemen, who unwittingly fostered the advance in the first place by overgrazing. “Because dense mesquite outcompetes grass for water and light and because mesquite groves don’t support fire, this conversion is permanent (on a human time scale) without physical intervention,” according t…
Mesquites as Botanical Friends
- If mesquites have arrived as intruders in the view of cattlemen of the Southwest, they have, by contrast, long been a welcome presence in the larders, livestock feed bins, workshops, gardens and medicine cabinets in the perspective of many desert residents. Cabeza de Vaca, in his Adventures in the Unknown Interior of America(translated and edited by Cyclone Covey), said th…
Something That Belongs
- Uninvited guest or welcome neighbor, the mesquites belong to the desert. They evolved in the desert. They play a core role in the desert ecosystem. They both provoke and benefit the people of the desert. “It comes as near being characteristic of the whole Southwest, including much of Mexico, as any species of plant life known to the region,” said Dobie. “I ask for no better monum…
