Information about Grasses

Here is the Species List of grasses on the property.

Here are the References we've used in building up this information.

Below are our photos of grasses on the property.

There are about 40 species of native grasses on the property, but also a dozen exotics. The information in this page is primarily from MP (1.8 p. 7, App. B pp. 37-41, App. D pp. 43-47).

We've defined 'grass' broadly and pragmatically, by including:

In the moist areas, the dominant grasses are:

In the moister areas, other local grasses include:

with invasions by:

In the dry areas, the dominant grasses are:

In the dry areas, other grasses include:

A couple of areas of Serrated Tussock (Nasella trichotoma – all too similar to Stipa setacea!) have been whittled away, along the main ridge and on the eastern side of the northern block (100 in 2009, 60 in 2010, 20 in 2011).

Other local grasses mentioned in MP (pp. 37-41) are:

Summer – 28 December 2010

The time was (only just) right to do a trial harvest of Themeda australis seed. But Tim Booth (of Captain's Flat Rd, Queanbeyan) only had a short window available, so we went ahead. The purpose was to prevent the Kangaroo Grass becoming too dense and hence squeezing out forbs and reducing diversity. Tim uses a bush harvester called a 'Grass Hopper', which is manufactured in Cooma. It has a spinning brush on a horizontal axis, which draws the heads into the hopper. It only captures about 20% of the seed-heads that it passes over, and the head does no apparent harm to the remainder.

The bigger risk is the wheels of the Grass Hopper (which is drawn in a path offset from the ute) and then of the ute itself. As the ute and trailer run clockwise, concentrically, each track is run over three times, resulting large tracts of beaten-down grass. It looked roughly like a wombat had gone over it 3 or 4 times in quick succession. When pushed up with the foot, however, the long stalks sat vertically again, i.e. they were pushed over not broken.

Some areas with relatively thick cover had to be left alone because the surface was too wet (with a number of springs evident – suggesting to Tim a granite shelf a short distance underground) and/or the slope was a bit too steep to get back up without damaging the grass and risking wheel-spins and bogging. Two small stretches were damaged, and pushed back down with the boot.

To empty the hopper, Tim first left the door open and let the squirming mass of caterpillars, flies, grasshoppers, spiders, etc. work their way towards the light and make their bid for freedom (pictures on the animals page). He then spread the catch on a tarp to begin drying. When he was ready to leave, he bundled them up, to take them home, finish drying them, and then sell on to a specialist who knows how to extract the seed. The northern paddock ridges would have been likely to offer some further opportunities for cropping, but the crossing was too wet to get there. The ridges in the rest of the middle block, and the flatter areas in the southern block weren't dense enough to need harvesting (nor, from Tim's viewpoint, be worth the time and effort).

Echidna Ridge provided a couple of hoppers' full of seed-heads. Tim later said that this yielded about 50kg of dried florets. In much denser Themeda at Guy's Cross the next day, he harvested about 120kg in the same time. We all suspect that the species diversity there is lower. ('It stands to reason', as they say). So our feeling is that this intervention has been performed at about the right time, i.e. before the Kangaroo Grass becomes too dense and squeezes out the forbs. The next challenge is to work out whether it needs to be an annual, biennial or occasional event, and whether and when the other, less dense areas need the same treatment.

It's been a warm and wind-dried summer. Yet the rainfall's been odd – 2013 had 4 big months, most recently Nov, with 8 low-rainfall months, and a total 9% above long-term average. Poas and Stipas were healthy, Dichelachne wasn't greatly in evidence, and there were four surprises, with three new species, and two Sorghum plants that we hadn't seen before

Mid-Spring – 3 October 2015

The start of spring was delayed considerably, due to the cool mornings lasting a month longer than usual. This was the first real heat, with three 28-30 degree days over the long weekend. The ground was dry, presumably due to persistent winds (very strong indeed on Saturday night). The water table was high, the dam still fairly full.

Species seen in the North and Centre blocks – (F means in Flower):
Aust seta, Junc usit, Loma mult, Luzu dens, Micr stip, Plan vari F, Poa labi, Poa sieb, Them aust;
Introduced: Anth odor F, Holc lana , Plan lanc.


Mid-to-Late Spring – 21 October 2015

Species seen on Echidna Ridge and in or near Gate Gully (F means in Flower):
Loma fili F (very small, yellow, just below track above small dam), Luzu dens, Plan vari F, Poa labi, Poa sieb, Scho apog F, Them aust;
Introduced: Anth odor F, Holc lana F (just starting), Pasp dili, Phal acqu

Visit by NCT's Nigel Jones and Rainer Rehwinkel.

These 4 were in flower: Anth odor (I), Holc lana (I), Scho apog (very widespread), Them aust (young inflorescences at this stage were only in the waterlines)

Plus these 5: Aris ramo, Aust carp, Briz mino (I), Hook erio, Micr stip

Early Spring – 15 October 2016

The season had finally got moving, a mere week later. The dams and waterlines were still full, but barely running, the various springs were easing off, and the ground in the lesser waterlines was moist rather than wet.

Emergently noticeable were (only): Carex brev, Luzul sp.

Spring – 9 November 2016

Sweet vernal was far too much in evidence, and Yorkshire Fog was also heading up.

Of the natives, those that were advanced were Loma (fili?), Poa meion, Schoe apog.


Future Activities

  1. Themeda australis
    In some areas, Kangaroo Grass is becoming somewhat dense and matted, particularly on the western end of Echidna Ridge.
    As seen at Turallo Nature Reserve just south of Bungendore, this not only denies space for forbs, it also results in the Themeda dying off, and introduced species taking over the space.
    We intend devising a trial low-intensity burn (incl. pre-photos and a control plot) in that area
