Mechanistic invasive species management models and their application in conservation
Conservation Science and Practice, Volume 3, Issue 11, November 2021., 2021 Management strategies to combat the impacts of invasive species are critical for effective conservation. Mathematical models provide insight into invasive populations, and help to identify cost‐effective prevention, control, and eradication actions, although the complexity of these tools is often inaccessible to conservation practitioners making ...

The Role of Citizen Science in Earth Observation [PDF]
, 2017 Citizen Science (CS) and crowdsourcing are two potentially valuable sources of data for Earth Observation (EO), which have yet to be fully exploited. Research in this area has increased rapidly during the last two decades, and there are now many examples

Grassification and Fast-Evolving Fire Connectivity and Risk in the Sonoran Desert, United States
Frontiers in Ecology and Evolution, 2021 In the southwestern United States, non-native grass invasions have increased wildfire occurrence in deserts and the likelihood of fire spread to and from other biomes with disparate fire regimes. The elevational transition between desertscrub and montane

Simulating long-term effectiveness and efficiency of management scenarios for an invasive grass
AIMS Environmental Science, 2015 Resource managers are often faced with trade-offs in allocating limited resources to manage plant invasions. These decisions must often be made with uncertainty about the location of infestations, their rate of spread and effectiveness of management ...

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 ...

Remote Sensing in Ecology and Conservation, 2019 Methods to detect and monitor the spread of invasive grasses are critical to avoid ecosystem transformations and large economic costs. The rapid spread of non‐native buffelgrass(Pennisetum ciliare) has intensified fire risk and is replacing fire ...

Predicting Buffelgrass Survival across a Geographical and Environmental Gradient [PDF]
Journal of Range Management, 1995 This research was designed to identify relationships between T4464 buffelgrass (Cenchrus ciliaris L.) survival and climatic and soil characteristics. At 167 buffelgrass seeding sites in North America we collected climatic and soils data where the grass: 1) persisted over time and increased in area covered (spreads), 2) persisted over time but does not ...

Detecting new Buffel grass infestations in Australian arid lands: evaluation of methods using high-resolution multispectral imagery and aerial photography [PDF]
, 2013 We assess the feasibility of using airborne imagery for Buffel grass detection in Australian arid lands and evaluate four commonly used image classification techniques (visual estimate, manual digitisation, unsupervised classification and normalised ...

Molecular characterization of new Buffelgrass (Cenchrus ciliaris) genotypes
Plant Omics, 2020 Buffelgrass (Cenchrus ciliaris L. Link) is an African agamospermous grass that has been widely introduced into arid regions of the world to improve rangelands for cattle production and as a result, it has invaded adjacent habitats. Cenchrus ciliaris is apomictic, a condition that is normally associated with low genetic variation within populations, but
