Orchids in the parks now!

The wildflowers are flowering!

When you are out and about in the Parks look out for our wildflowers including our native orchids.

The orchid pictured on the right is Pyrorchis nigricans the fire orchid, or Red Beaks.

We were very pleased that Kate shared her finding with the team at the Biology Society of SA event in September.

Seeds SA website tells us that this species is of least conservation concern in the Adelaide Hills FLB01, but is critically endangered in FLB02 (Broughton) and the Southern Flinders - FLB04  Seeds SA reference

It is fun and exciting to look for and photograph orchids.  So exciting that you want to share your find on iNaturalist.  If you choose to do this, we recommend setting the geospacial privacy to "obscured" to avoid other avid orchid watchers from disturbing the site looking for it.

I was surprised to see so many of these small orchids.  What I noticed was they seemed to be hiding amongst the fumitory and three corner garlic.  I had been told by someone in the Orchid Society that the bulbous weeds, like the three corner garlic, were one of the greatest threats to our orchids.  But in this case, it did get me to wondering.  Why were all the orchids I saw surrounded by weeds?
Could the weeds in the main valley, especially the three corner garlic be having a protective effect.  My musings entirely, but just maybe, nestled amongst the weeds, they are less likely to be picked by humans (all the ones I saw were white) and maybe the three corner garlic is a deterrent for the rabbits?
For the moment, I am thinking that we should avoid disturbing them, and instead make a record of how many we find and in what locations, so that we can compare year to year what is happening to the population. Is what we are doing helping them, or hindering them?  While it is just one species, it might tell us a bit about the priorities we need to consider when working in the park.
