Grass levels were moderate. Tree and weed pollen counts were low. Tree pollen included bottlebrush (Callistemon sp.), sand olive (Dodonaea sp.) and pine (Pinus sp.). Weed pollen types detected were the daisy family (Asteraceae), spurges (Euphorbiaceae sp.), goosefoot (Chenopodiaceae) and peaks of slangbos (Stoebe type). Mould levels were low.


Grasses were moderate. Trees were low and included waxberry/bayberry (Morella sp.), pine (Pinaceae), Australian pine or beefwood (Casuarina) and eucalyptus (Myrtaceae). Low weed levels were detected, and the pollen types were mugwort (Artemisia), the daisy family (Asteraceae), English plantain (Plantaginaceae) and nettle (Urticaceae). Moulds were low but some significant spikes for Alternaria were noted.


Grass levels were high. Trees were low and only Australian pine/beefwood (Casuarina) and waxberry/bayberry (Morella sp.) were detected. Low weed levels included the daisy family (Asteraceae), goosefoot (Chenopodiaceae) and protea (Proteaceae). Mould levels were low overall but significant Alternaria levels (including a strong spike on 29/03) were detected.


Grass, tree and weed pollen levels were low. Tree types detected were eucalyptus (Myrtaceae), pepper tree (Schinus sp.) and mulberry (Moraceae). Weeds detected were sorrel (Polygonaceae), the daisy family (Asteraceae), goosefoot (Chenopodiaceae), sedges (Cyperaceae), ferns (Polypodiaceae) and waxberry (Myricaceae). Mould counts were moderate.


Grasses remained low at this site. Tree pollen levels were low and eucalyptus (Myrtaceae), Australian pine or beefwood (Casuarina), waxberry/bayberry (Morella) and species from the Anacardiaceae family (Rhus sp., Schinus sp.) were detected.
