The UF/IFAS Assessment of Nonnative Plants in Florida’s Natural Areas: History, Purpose, and Use

Abstract

Nonnative invasive plant species pose a significant threat to Florida’s natural areas. The UF/IFAS Assessment of Nonnative Plants in Florida’s Natural Areas (hereafter, UF/IFAS Assessment) uses literature-based risk assessment tools to predict the invasion risk of both nonnative species that occur in the state as well as species proposed for introduction. The UF/IFAS Assessment team has evaluated more than 770 species, including 97 species proposed for introduction or new uses. The team is actively identifying and evaluating potentially problematic nonnative species (and sub-specific or hybrid taxa). Recommendations and supporting information from the UF/IFAS Assessment can be found at http://plants.ifas.ufl.edu/assessment. This 6-page fact sheet was written by Deah Lieurance, S.

Ectoparasite infestation on cattle husbandry in oil palm plantation afdeling II, North Sumatra

“…Fly breeding sites are often in dirty and odorous places, such as livestock dung and decomposing organic materials like rotting oil palm leaves. The optimal temperature for fly development is 33-35°C, and their populations decrease when the temperature exceeds 45°C or drops below 10°C [38]. The temperature range supporting maximum fly development is between 25-35°C [39].…”
