Summary Moulds increased sharply in KwaZulu-Natal, following heavy rains in this subtropical climate zone. Strong spikes for ascospores and basidiospores (includes mushrooms) were seen. Pollen levels were low at all the sampling sites except Calvinia, where a small spike in the grass counts was observed. Trees were very low at all the sampled sites and […]

Summary Tree and weed pollen levels were low at all the sites. Grasses were moderate in Kimberley, Calvinia and Bloemfontein but have decreased to low levels at all the other sampling sites. Moulds were moderate in Durban, but low across the rest of the country. Cape Town Grass, tree and weed levels were low at […]

Summary An increase in tree pollen was seen in Cape Town, with an increase in weed pollen in Pretoria. Grass counts were moderate in Kimberley and likely similar in Bloemfontein (no new data available). High fungal spore counts were recorded for Cape Town and Durban. Cape Town High fungal spore counts were seen. Grass and […]

Summary Across South Africa, pollen and fungal spore levels were low during this sampling period. Moderate mould counts were recorded in Bloemfontein and Durban, and tree counts in Bloemfontein were also approaching significance. Cape Town All pollen counts were low during this sampling period. Trees identified included gum (Myrtaceae), Australian pine (Casuarina sp.), forest elder […]

Summary Overall low pollen and fungal spore levels were seen across South Africa. Although no new data were available for Durban, predicted counts for this time of year show moderate fungal spore levels. Cape Town All pollen categories were low during this sampling period. Trees included the sumac family (Anacardiaceae), cypress (Cupressaceae), waxberry (Morella sp.), […]

Summary Low levels of pollen and fungal spores were seen across South Africa. Cape Town Low levels of grass, trees and weeds were seen. The trees detected included the sumac family (Anacardiaceae), Australian pine (Casuarina sp.), cypress (Cupressaceae), waxberry (Morella sp.) and gum (Myrtaceae). The weeds were mugwort (Artemisia sp.), the daisy family (Asteraceae), goosefoot […]

Summary Overall low pollen and fungal spore counts were seen. Although no new data were available for Durban, the mould counts should be moderate at this time. Cape Town Low pollen levels as well as fungal spore counts were seen during this sampling period. Tree pollen included the sumac family (Anacardiaceae), cedar (Cedrus sp.), cypress […]
1 July 2022
Summary Low temperatures with frost at night depressed the mould/fungal spore loads in some inland cities. In coastal cities with milder weather small peaks in airborne mould spores were noted. in Kimberley 40 mm rain in one day removed pollen and mould from the air so the counts were extremely low for the final three […]
8 July 2022
Summary: Pollen and mould spores remained low during this mid-winter sampling period, where minimum temperatures were as low as 1ºC in some inland cities. Signs of spring were seen in the tree profile in Gauteng, where oak and plane tree pollen is slowly increasing. Weed pollen was very low in all sampled areas of South […]
