How to know if your grasslands are grassland or grassland-like
The top three things that grasslands do well: – They have plenty of nutrients – They are often covered in tall grasses – They can be dry at times, but will grow in water – They produce a lot of water – Grasslands are generally not water intensive, but are also rich in nitrogen, phosphorus and other nutrients.
The Australian Grassland Council says grasslands have been the keystone species for Australian biodiversity for more than 10,000 years.
The organisation says grassland is also a keystone for Australian agriculture.
Aussie Grassland council executive director, Tony Bennett, said there was little research that had looked at whether the different types of grassland were different in terms of the nutrients they were capturing and the type of vegetation they contained.
Mr Bennett said grasslands had been “one of the most important ecosystems in the world” for more years than they had been discovered.
“They are not just a natural habitat, they are a social habitat, an economic habitat, a biodiversity habitat,” he said.
“In terms of food production, they provide an economic stimulus for the human population.”
The Australian National University’s Professor Peter Gough said the research was encouraging.
“The more we look at grassland, the more we see it is one of the greatest systems of biodiversity on earth,” he told ABC Radio.
“I think it’s important that we look beyond just the type or the size of a grassland.
It’s not just about the size and the quantity of grasses it’s the ecosystem, it’s what they’re doing that has value.”
The research involved researchers monitoring over 20,000 grassland sites in NSW and Victoria between 2002 and 2014.
Professor Gough says the research suggests there was a relationship between the size, type and the nutrients in the soils.
“One of the key aspects of that study was that the nutrients that the plants in the soil had were associated with the type and composition of the soil,” he explained.
In addition to the nutrients, grasslands contain an array of other organisms that are also important for the ecosystem. “
And what this research has found is that the composition of soils in a grassy environment are not necessarily the same as those that are in a woody environment.”
In addition to the nutrients, grasslands contain an array of other organisms that are also important for the ecosystem.
For example, “a lot of those organisms are actually very important because they do help with the photosynthesis of carbon dioxide, they do support the uptake of water and they also can help with nitrogen fixation and decomposition,” Professor Goug said.
A new study has found that a species of grass on a site is more likely to grow than one from a different species of vegetation.
This study, published in the journal Science, looked at the nutrient composition of more than 200 species of plants in Australia.
It found that “the average abundance of nitrogen and phosphorus in a particular species of plant varied between one-quarter and one-third that of the species in a different location,” the researchers said.
The study also looked at how many species of the same species were in different locations on the same site, looking at the nitrogen content of their roots and how they varied over time.
This showed that when the plant was located close to a source of nitrogen, its roots were in the same location, but when it was further away from a source, the nitrogen concentration in the roots was lower.
“That suggests the soil may be better at retaining nitrogen and phosphorous than the plants that are closest to the source of the nitrogen,” Professor Bennett said.
It was also revealed that grasses in the vicinity of a source would be more likely than those in the opposite location to be eaten by ants.
The researchers also found that the presence of a small amount of phosphorus in the area around a plant increased the likelihood of a plant becoming an invasive species, whereas a large amount of phosphate increased the chance of an invasive plant becoming a grass.
Professor Bennett and his team are currently working on a study that looks at how a different type of plant would affect the environment of a community.
“There is a whole host of research being done by the community, by environmental scientists, on how to improve the quality of the environment and that’s why this study is so important,” Professor Benn said.
