An increase of biological invasion in developing countries is threatening smallholder’s livelihoods, biodiversity conservation, agroecosystems and rangeland productivity. In Tanzania, the exotic invasive plant Parthenium hysterophorus, which is rapidly spreading in Arusha region, threatens wildlife conservation, human well–being and food security in the country. This study was conducted to assess the current distribution of P. hysterophorus and its associated soil properties within the Arusha National Park (ANP) and in adjacent villages at the park’s border zones using road surveys. Parthenium hysterophorus density was visually estimated as high, medium, and low when the invasive individuals were > 4, 3–4, and 1–2 in 1 m2 quadrats, respectively. The results showed that albeit some adjacent villages are invaded, ANP is yet not affected. Parthenium hysterophorus was observed growing in grazing areas, maize and banana fields in villages, and along road verges, with particularly high densities in maize fields, along roadsides, and at lower altitudes. Moreover, analysis of soil chemical properties showed that P. hysterophorus was associated with soils of higher Manganese and cation exchange capacity. We recommend that P. hysterophorus surveys within the ANP and other protected areas in Arusha region should be carried out regularly as the rapid expansion of P. hysterophorus threatens ANP’s ecology and biodiversity.
