Ehrharta erecta
We find Ehrharta erecta (Veldt grass) to be, like kikuyu, a much more destructive ground cover than Tradescantia. Confirming our impression of Ehrharta erecta's spread and impact on revegetation in local reserves and neighbourhoods, we found the following:
Vegetative reproduction occurs and seed is produced in large quantities all year round (Timmins & MacKenzie 1995). Seed dispersal is by wind, water and bird.
TOLERANCES). [NZPCN]
Whereas a Tradescantia-covered margin can be weeded easily and gradually as native seedlings develop in it, Veldt grass multiplies rapidly, covers the ground with a dense firmly-rooted wiry mesh, and is rarely uprooted successfully and completely.
When uprooted, Veldt grass leaves many seeds behind, and they apparently germinate within 5 days.
"The plant is drought and shade tolerant and very tolerant to shade (Timmins & MacKenzie 1995). [NZPCN]
It is also tolerant of poor, sandy or rocky soil, and of deep leaf litter, as seen in the forest edge along the Kaipatiki Esplanade Walkway, in loose-metal wash-off from the Walkway and in deep leaf litter under sycamores and pin oaks.
Where Ehrharta is present nearby, we remove Tradescantia only successively, in small quantities, and ongoing monitoring of the released areas.
