Mesquite, Tobosagrass, and Common Broomweed Responses to Fire Season and Intensity
There has been increasing interest in the use of summer fires to limit woody plant encroachment on grasslands, but information regarding effects of such fires on perennial grass recovery and annual forb production is also needed. Our objective was to examine effects of fire seasonality and intensity on the woody legume honey mesquite (Prosopis glandulosa Torr.), the C4 midgrass tobosagrass (Ple...
متن کاملStrategies for Savanna Restoration in the Southern Great Plains: Effects of Fire and Herbicides
Woody plant encroachment has degraded grassland and savanna ecosystems worldwide by decreasing herbaceous production and diversity, and altering these physiognomies toward woodlands. This study evaluated the long-term efficacy of fire and herbicide restoration strategies used in the southern Great Plains to reduce Honey mesquite (Prosopis glandulosa) dominance, restore a grassland/savanna physi...
متن کاملModelling the trade-off between fire and grazing in a tropical savanna landscape, northern Australia.
As savannas are widespread across northern Australia and provide northern rangelands, the sustainable use of this landscape is crucial. Both fire and grazing are known to influence the tree-grass character of tropical savannas. Frequent fires open up the tree layer and change the ground layer from perennials to that dominated by annuals. Annual species in turn produce copious quantities of high...
متن کاملDevelopment and Management of Mesquite Savanna Using Low Intensity Prescribed Fires
Density of honey mesquite (Prosopis glandulosa) has increased in the southwest USA during the last century. Mesquite in dense thickets reduce grass production and plant species diversity. Prescribed frre is currently the least environmentally challenged and most economically sustainable option to manage mesquite. However, few mesquite over 1 year old are completely killed by frre. Moreover, the...
متن کاملMesquite savanna development using low-intensity fires and Reclaim herbicide
Introduction Mesquite in dense thickets reduce grass production and make livestock management more difficult. To compound the problem, treatments which top-kill mesquite, such as chaining, shredding, high-intensity fires, or herbicides such as 2,4,5T or triclopyr (Remedy), stimulate regrowth from stem bases and increase stem number per plant and per land area (Fisher et al. 1959). An alternativ...
