Recreating the Country blog
Trouble from the Veldt has appeared in my ‘backyard’ in the form of three invasive grasses that are threatening to displace remnant grasslands in three reserves that I help manage. The indigenous plants that have succumbed are extremely tough and hardy, but they are no match for this trio from the Veldt.
The South African Veldt is a wide open plain and its literal translation from Afrikaans is ‘field’, originating from Old Dutch. In South Africa the Veldt can be predominantly grasslands or a combination of grassland with shrubs and open woodlands. This type of landscape will sound very familiar to Australians.
Because of its exposed, dry climate the Veldt has produced plants that are very tough, so not surprisingly the Veldt grasses that were introduced to Australia as pasture grasses and for binding sandy soils, have adapted so well that they have invaded many waterways and nature reserves in Western Australia, South Australia and Victoria.
The three Veldt grasses causing the trouble are Panic Veldt Grass, Ehrharta erecta, Annual Veldt Grass, E. longiflora and Perennial Veldt Grass, E. calycina. Each species of grass is very invasive, fast growing, have done well in the extreme dry of the recent drought years and adapt well to wet years as long as the soil is well drained. They seem pretty bullet proof though some chinks in their armour are beginning to appear
In Central Victoria near Teesdale and Inverleigh which is my backyard, these Veldt grasses have invaded grasslands and grassy woodlands, displacing many of the indigenous grassland plants. Disappointingly they are not considered pest plants by government departments, though the Departments will indirectly fund their control because they are causing a loss of biodiversity values. Disappointingly this troublesome trio are not declared pest species because they are not a pest for the farming community.
