The USA National Phenology Network's Buffelgrass Green‐up Forecast map products

Ecological Solutions and Evidence, 2021
Buffelgrass (Cenchrus ciliaris syn. Pennisetum ciliare) was introduced to Sonoran Desert in the early 20th century and has become widespread at low elevations. This perennial bunchgrass accumulates abundant biomass that can carry fires through ecosystems

Uprooted buffelgrass thatch reduces buffelgrass seedling establishment [PDF]

Arid Land Research and Management, 2016
ABSTRACTBuffelgrass (Pennisetum ciliare (L.) Link), a non-native perennial bunchgrass, invades ecologically intact areas of the Sonoran Desert. It competitively excludes native plants and increases fire frequency and intensity. Since the 1990s, whole buffelgrass plants have been manually uprooted and removed to control the invasion in southern Arizona.

Top-down Green-ups: Satellite Sensing and Deep Models to Predict Buffelgrass Phenology [PDF]

arXiv.org, 2023
An invasive species of grass known as"buffelgrass"contributes to severe wildfires and biodiversity loss in the Southwest United States. We tackle the problem of predicting buffelgrass"green-ups"(i.e. readiness for herbicidal treatment).

Hydroclimatic Rebound Drives Extreme Fire in California's Non-Forested Ecosystems. [PDF]

Glob Chang Biol
Hydroclimatic rebound occurs when unusually wet periods are followed by intense drying, or vice versa, creating sharp moisture swings. We show that this process drives extreme fire activity in California's non‐forested regions, such as deserts and Mediterranean ecosystems, and was particularly evident in the 2025 Los Angeles wildfires.

Relationship between local-scale topography and vegetation on the invasive C4 perennial bunchgrass buffelgrass (Pennisetum ciliare) size and reproduction

Invasive Plant Science and Management, 2023
Buffelgrass [Pennisetum ciliare (L.) Link] is an invasive C4 perennial bunchgrass that is a threat to biodiversity in aridlands in the Americas and Australia. Topography influences P.

Land tenure contributions to protected area growth under alternative conservation targets in the Australian monsoon tropics. [PDF]

Conserv Biol
Abstract As the global protected area (PA) network expands to meet international targets, it is important to assess whether traditional reliance on public land will suffice for projected PA growth or whether other tenures, such as Indigenous or pastoral lands, may increasingly contribute.

Arthropod associates of Kenyan buffelgrass (Cenchrus ciliaris): a field survey for biological control candidates of a globally important invasive grass

African Entomology, 2023
Invasive species are the second largest contributor to biodiversity loss and drivers of ecosystem change. Buffelgrass is a C4, perennial grass native to Africa and Asia that was widely introduced across tropical and subtropical rangelands as livestock ...

Spittlebug and Buffelgrass Responses to Summer Fires in Mexico [PDF]

Journal of Range Management, 1999
Summer burning was used to reduce spittlebug (Aeneolamia albofasciata Lall.) populations in buffelgrass [Cenchrus ciliaris (L.) Link] on the Carbo Livestock Research Station in Sonora, Mexico. Five treatments included (1) an untreated control; (2) burning 7-14 days before the summer rains when the insect and the plant were inactive; (3) burning after ...

Can competition with pasture be used to manipulate bellyache bush (Jatropha gossypiifolia L.) population biology? [PDF]

, 2013
Bellyache bush (Jatropha gossypiifolia L.) is an invasive weed that poses economic and environmental problems in northern Australia. Competition between pasture and bellyache bush was examined in North Queensland using combinations of five pasture ...

Biocrusts do not differentially influence emergence and early establishment of native and non‐native grasses

Ecosphere, 2021
Biological soil crusts (biocrusts) cover the soil surface of global drylands and interact with vascular plants. Biocrusts may influence the availability and nature of safe sites for plant recruitment and the susceptibility of an area to invasion by non ...
