Kimberley

Low pollen and fungal spore levels were seen during this sampling period and only grass and weed (daisy) pollen was detected. Fungal spore levels were very low.

Gqeberha

Pollen levels remained very low but tree pollen (pine, eucalyptus and alder) was detected. Low weed (daisy and English Plantain) and grass pollen levels were observed. Fungal spores were low but increased briefly following rain.

Cape Town

Intermittent rain reduced ambient pollen to low levels. Grasses, weeds (English Plantain) and a few tree pollen grains (pine only) were detected. All fungal spore levels were consistently low as temperatures decreased during a late cold spell in the Mother City.

Bloemfontein

All pollen and fungal spores were very low during this sampling period. Tree pollen levels were similarly low and the tree species detected were: Bush willow, oak, pine, buddleia, white stinkwood and acacia. Fungal spores were low throughout.

Pretoria

Fungal spore loads were low. Grass, tree pollen: ash, cypress, birch, mulberry, olive, pine and eucalyptus was low. Weed pollen levels (goosefoot only) was very low.

Johannesburg

All pollen levels were very low. No grasses were detected and trees: ash, eucalyptus, olive, pine and oak levels were low. Low levels of weeds: English Plantain and Caryophyllaceae (family carnation) were seen. Fungal spores were very low during this arid sampling period.

Durban

Pollen levels were low. Low grasses and trees: pine, acacia and mulberry and a few weeds: goosefoot and English Plantain were detected. Fungal spore levels were extremely high and daily counts of >30 000 were seen for ascospores, but Cladosporium, an allergenic mould levels increased too and exceeded 1 000 spores/day. Small peaks were seen for basidiospores (includes mushroom spores).
