2020 started like most other years but that didn’t last for long. March is the anniversary of when the world went into lockdown. All due to Covid 19!
So like most other organisations here in Adelaide, NOSSA was immediately and suddenly impacted. All plans went out the window. Face to face activities ceased and it was some months before even a semblance of meetings resumed.
Yet despite all the difficulties and challenges, when the committee looked back over the year we were amazed at what we did achieve and so here is our list of 2020 – Covid19 could not keep us down!

AGM
Delayed but not out. Held in September (instead of March) via Zoom and face-to-face meeting.
Committee Meetings
Following a brief hiatus, the committee made use of email communications and then Zoom meetings. From June the committee used a mix of face-to-face and Zoom meetings.
Finally the opportunity to have members present when unable to attend!

So many of us are interested in preserving our native flora and fauna, and for NOSSA it is the native orchids. But many of us may not be aware of how we can play a significant role in minimising our impact upon the environment so that they are still around for our children and grandchildren
The following video is a brief overview of two documents that NOSSA has produced. They are guidelines to help individuals know how they can minimalize their impact on the environment and so assist in the conservation of our beautiful and unique native orchids.
Below are the links to the documents referred to in the video:
Sadly many of our orchids are under threat of extinction.
Fortunately, conservationists and researchers are putting in a lot of effort in an attempt to save them. Part of this work consists of caging and tagging individual plants.
Most people do the right thing and do not disturb the cages/tags. Unfortunately some, hopefully mainly through lack of knowledge, do move them. Sadly, too many of them are being moved. Sometimes they are re-positioned but not always.
There are a good reasons for the individual plants to be tagged/caged. And there are good reasons for not moving either the tags or the cages.
Tags
Tags are usually numbered. These numbered tags are reference locations from which the distance and bearing of plants are measured. If the pin is moved the record for that individual plant is invalidated. Position of pins are used to determine if plants reappear in succeeding years.
Replacing the pins can also result in inadvertently spearing, and thus destroying, the tubers.
Cages
Cages are used to protect individual plants from grazing. Moving cages, even if returned, can result in damage to the plant, as well as damage to any emerging juvenile plants.
NOSSA & Conservation
One of the main activities of NOSSA is conservation. Many of our members assist in the work of monitoring, caging and tagging of plants. They know of the time and effort required for this work. They know why it is important not to move tags or cages, not even for taking photographs.
But we are aware that there are those who do not know and so would ask that others pass this message onto friends who may be unaware of the significance of cages/tags.
So simply put, “Cages & tags are not to be moved under any circumstances”.
A small but varied number of entries for our first competition of the year. Andrew Primer entered a lovely picture Thelymitra azurea from Eyre Peninsula; Thelma Bridle entered Calochilus cupreus one of South Australia’s endangered orchids; John Fennell’s close up of Caladenia prolata and Rob Pauley’s mass flowering of Caladenia carnea.
The winner was Rob Pauley’s C. carnea a wide spread orchid which ranges from across the Eyre Peninsula through to the South East as well as occurring in the Eastern States and Tasmania. Although considered common both nationally and at a state level, there are regions within its range where it is considered to be Near Threatened, Rare and even Vulnerable. Also, despite being common, the Seedbank notes that there are areas of probable decline: Fleurieu (KAN02), Mt Lofty Ranges (FLB01), Eyre Mallee (EYB05), Wimmera (MDD05) and Southern Yorke (EYB01). It is a reminder that not only the rarest species but also that common species can be in decline.
The situation is complicated by taxonomic issues; C. carnea is not only a highly variable species but also a complex of several similar species plus many undescribed species which continues to challenge botanists.
The Native Orchid Society of SA has been involved with the Threatened Orchid Project which is attempting to propagate some of our most threatened orchids. There has been some success such as Thelymitra epicaptoides (Metallic Sun Orchids) but others are proving elusive. Marc Freestone, from the Orchid Conservation Project, Royal Botanic Gardens Victoria, is a PhD student who is researching one such difficult to grow orchid genus, the Prasophyllum.
Prasophyllum murfettii (Denzel’s Leek Orchid)
To assist with his research Marc has the sent the following request.
CAN ANYONE GROW LEEK ORCHIDS?
South Australia has about 40 species and Victoria about 74 species of the native Leek Orchids, Prasophyllum. Some are on the brink of extinction.
A major problem hampering efforts to prevent our Leek Orchids from going extinct is that they have proven next to impossible to grow in cultivation. They have proved extremely difficult, usually not germinating at all, or germinating but then dying soon after. Occasionally some success has been had (particularly with symbiotic germination) but successful germination trials to our knowledge have so far proved un-repeatable. Working out how to grow Prasophyllum is critical for the survival of many species at risk of extinction across southern Australia.
To try and change this, I will be studying Prasophyllum and their relationships with symbiotic mycorrhizal fungi.
But I need your help!
I am wanting to hear from as many people as possible who
have tried (either successfully or unsuccessfully) to grow Leek Orchids or the closely related Midge Orchids (Corunastylis).
have observed Leek Orchids (or Midge Orchids) recruiting from seed in the wild.
If you can help, or know of anyone who might be worth talking to, please contact me at: marc.freestone@rbg.vic.gov.au or 0428 304 299.
(Funding and support for this project: Australian National University, Federal Government National Environmental Science Programme, Royal Botanic Gardens Victoria, University of Tasmania).
I would encourage people to contact Marc with whatever information that you have, no matter how insignificant you may think it is. Every little bit helps including unsuccessful attempts.
His eventual aim is to be able to work out how to grow them reliably from seed in cultivation.
There are many different activities involved with orchid conservation. In situ conservation consists of looking after the orchids where they are growing; maintaining and protection of habitats and ecological systems. On the other hand ex situ conservation is caring for the orchids in cultivation in a similar way that zoos maintain an animals species that is extinct in the wild.
For the orchids one form of ex situ conservation is via seed collection and the propagation of new plants. With many of our terrestrial orchids this is not an easy task but here in South Australia an attempt is being made with four of our endangered orchids.
Unlike some of our terrestrial orchids these are ones which we have not been able to grow. There is a collaborative effort co-ordinated through the South Australian Seed Conservation Centre (Seedbank) to change this. Amongst the people helping the Seedbank are members of the Native Orchid Society of South Australia, students from Kildare College and Dr Noushka Reiter of the Royal Botanic Gardens Melbourne.
On July 30 2016, Dan Duval of the Seedbank was interviewed by Jon Lamb on Ashley Walsh’s ABC 891 Adelaide Talkback Gardening program. It is an informative interview and well worth the listen.

Video as heard on Talkback Gardening with Jon Lamb and Ashley Walsh – Saturdays from 8.30 on 891 ABC Adelaide.
Spring is here and it was reflected in the variety and large number of entries. Lorraine Badger and Ros Miller entered Western Australian species – Caladenia x ericksoniae (Prisoner Orchid) and Paracaelana nigrita (Flying Duck Orchid) respectively. The other six entries were all from South Australia, Diplodium robustum (Common Green Shell Orchid), Caleana major (Flying Duck Orchid) both from Jane Higgs, Greg Sara’s Oligochaetochilus sp (Rufoushood), Judy Sara’s Arachnorchis leptochila (Queen Spider Orchid), Claire Chesson’s Diuris behrii (Cowslip Orchid or Golden Moths) and the outstanding winning picture Pterostylis cucullata by Bevin Scholz.
In many ways, Bevin’s picture of P. cucullata (Leafy Greenhood) is a special picture because it represents some of the conservation work with which NOSSA is involved. For many years NOSSA has worked with the Threatened Plant Action Group (TPAG) to weed the areas in Belair where this species is located and to see such a good show of plants is encouraging. It is a tribute to all who have contributed with their time and labour.
P. cucullata is rated Vulnerable both in South Australia and Victoria, and Endangered in Tasmania. It is also rated Vulnerable under the EPBC Act (Federal). Nationally it is known from about 110 sites with most of these sites being in Victoria and only a few sites in South Australia with Belair National Park having the largest and most important population for the state.
Historically this species covered an area of 2107 km2 in the Lofty Block region but that has now contracted by 82% to only 366 km2 with few locations. With such a reduced range, recovery plans were developed, both at state and federal level. The plans examined the risks and threats to the survival of the different populations.
One of the threats to this orchid is fire, including proscribed burns. Unlike some species such as Pyrorchis nigricans, Leptoceras menziesii or Prasophyllum elatum which flower well after fire, P. cucullata is fire sensitive; populations decline substantially. There does not seem to be a safe time to burn for this species. Should a population survive a burn, it would take it many years to recover.
Fire also leaves the population vulnerable to another threat, that of weed invasion. Unfortunately, it is weedy where this species survives but over the years, a consistent, targeted weeding program has resulted in a declining weed population. NOSSA and TPAG have appreciated the work and effort of volunteers and gladly welcome anyone else who would like to join. And one of the rewards? A beautiful, sunlit display of flowers as seen in Bevin’s picture.
The Native Orchid Society of South Australia (NOSSA) is affiliated with the national body of native orchid society, Australian Native Orchid Society (ANOS). NOSSA regularly sends reports of its to ANOS. This year’s report covered four years of the society’s activities and is reproduced here to give readers an idea of the many things that we do. This report was produced by Robert Lawrence (currently Vice President).
NOSSA REPORT 2012 to 2016
I believe that the last annual report from the Native Orchid Society of South Australia was in 2011 when we were just commencing a three-year plan with the establishment of a series of subcommittees. All of the committees have since ceased to exist, but not without significant accomplishments.
The Website Subcommittee had established a website, but a Webmaster has since been appointed. The website now uses WordPress and is maintained so that its management could easily be transferred to another person. The website provides a weekly educational post about Australian orchids. It has also provided a point of contact from those outside of the Society. It is linked to a Facebook page that increases the profile of NOSSA among those interested in orchids throughout Australia and beyond.
The Education Subcommittee had established a picture competition at the monthly general meetings. There is still only a small number of contributors, but many excellent pictures are shared. The winning picture from each meeting is used as a basis of one of the weekly posts on the website.
The Education Subcommittee had a vision to produce a brochure of 20 common orchids of the Adelaide region for free distribution to the general public. The NRM (Natural Resources Management) Education ran with the idea and produced a poster of Common native orchids of the Adelaide Hills. This provided brief, but comprehensive, profiles of 29 native orchids and the weedy species. This has been printed as a double-sided poster and is available from the website of Natural Resources Adelaide and Mt Lofty Ranges. NOSSA members worked with NRM staff on the details of the poster and NOSSA members contributed many of the photographs. This poster was completed and launched in April 2015.
NOSSA also provided monetary assistance as a loan with the publication of the field guide entitled, Start with the leaves. A field guide to common orchids and lilies of the Adelaide Hills. This guide covered 50 orchid species as well as native lilies and some weeds in the Iridaceae family that are sometimes mistaken as orchids. The contribution of $8,000 was recovered only 8 months after publication.
The Disc Publication Sub-editing Subcommittee saw the publication of South Australia’s Native Orchids on DVD discs in time for the Spring Show in September 2011. Both the DVD and the book were published in time for the Spring Show in September 2011. Both continue to sell.
A new subcommittee has been established in February 2016 to oversee the publication of a field guide, expected to be called Wild Orchids of South Australia. It is proving to be a challenge to be brief enough to reduce the information to a size suitable for a field guide. (Editor’s note: it has since been decided to defer this until after the development of the interactive website, see below.)
NOSSA members have being working since 2014 to establish an interactive website and database modelled on the Go Botany website run by the New England Wild Flower Society in the USA. This was supported by a grant from the Australian Orchid Foundation. The project is called Wild Orchid Watch. It is hoped to produce an interactive, web-based orchid identification tool. Recording sightings through such means as apps on mobile telephones are also being investigated.
In 2014 NOSSA made a donation to help establish the Orchid Conservation Program. This was led by Dr Noushka Reiter. Once established, staff in the Department for Environment, Water and Natural Resources began to organise a trial with four threatened orchid species from South Australia. Noushka visited South Australia during 2015 and collected samples from each of these species and isolated fungi from these. Seed was also collected and work on propagation commenced in 2015. During 2016 NOSSA sponsored the propagation of one of the four species through the Adelaide Botanic Gardens. Caladenia gladiolata, an endemic species, was selected.
Paul Beltrame, a secondary teacher at Kildare College, contacted and joined NOSSA during 2014 with the interest in getting girls at this school involved in the propagation of native orchids. A program was organised modelled in the Orchids in Schools program run by the Orchid Club of South Australia with Les Nesbitt’s involvement.
A delegation from Kildare College, ably assisted by their enthusiastic laboratory assistant Nenah McKenzie, visited Noushka in Melbourne and learnt the technique for separating and growing fungi. They have since separated fungi from two of our more common greenhood species and supplied this for seed kits that were made available to members as a trial at the start of the 2016 growing season.
The trial of seed kits was done for Pterostylis nana and Pterostylis sanguinea. A trial was conducted in this growing season of seed kits for members. Kits included a pot, growing media, seed, fungus, mulch and instructions. There seems to be limited success with the current round, but improvements are planned from the lessons learnt. One particular growing mix proved successful with a small number of seedlings appearing. The contribution of the Orchids in Schools program at Kildare College has been necessary for the isolation and production of fungi for the kits.
In October 2012 Cathy Houston and Robert Lawrence collected seed of Pterostylis arenicola from the only population on the Adelaide plains after monitoring in September indicated a good year for seed production. The seed was germinated in 2013 and was deflasked at a working bee at the Adelaide Botanic Gardens in early August 2016. The students from the Orchids in Schools program at Kildare College participated. Latest reports are that 40 plants look like surviving. These will be used for seed production and for reintroduction.

In 2012 NOSSA was asked to care for and propagate rescued Diuris behrii plants from Hillgrove Resources Mining Lease near Kanmantoo in the Mt. Lofty Ranges. The plan was to maintain the rescued orchid clones in cultivation for several years and to produce additional plants for reintroduction within the mining lease area each Autumn. A comprehensive recording and auditing system has been put in place to track each clone and any seed/daughter tubers/plants. By August 2015 there were 609 plants with 75 original mother plants. There were 95 daughter plants returned to the site for revegetation in each of the years 2014, 2015 and 2016, a total of 285 plants.
Funding from Hillgrove Resources has assisted NOSSA financially and has made it possible to consider funding conservation work. NOSSA is planning to apply for charity status so that donations can be used for tax deductions. Donations will then be feasible through our website. We are also starting an orchid seed bank. Seed will be available only to members and it is hoped that this will increase our membership. There is a demand for Australian orchids overseas and it is hoped that this will become a means for raising funds for conservation. Other means of fund-raising such as sausage sizzles and selling kits for craftwork are also being considered.
NOSSA members still continue to be involved in surveys and monitoring threatened orchids. Members have been involved in the planning of monitoring.
Weeding and Monitoring, two of NOSSA’s conservation activities
The management committee of NOSSA is currently working on a revision to the Rules of Association. In the current version there is a two-year limit on the term of the President of two years. In the first 16 years from 1977 there were there were eight different presidents before one had a second term. Bill Dear was president in alternate terms until he retired and moved to Western Australia in 2012. Robert Lawrence was elected president in March 2014, but for the first time in 2016 there were no nominations for president and he was nominated to the role of vice president with no other nominations. The management committee has appointed a subcommittee to review the Rules in relation to the terms of the president. Another change planned is change from having monthly general meetings to having less formal monthly meetings at which no decisions are made or minutes kept. All resolutions will require calling a formal special meeting. This idea is adapted from the approach used by ANOS Victoria.
Over the last two years NOSSA has asked new and renewing members to complete a survey of their interests. This has proved to be an effective way of getting information on the interests of our members with 79 responses, this being about half of the number of memberships. This is an overall summary of the results ranked according to number of responses:

At its establishment NOSSA was primarily a Society of orchid growers. These figures reflect a decline in interest in growing orchids. The figures are somewhat surprising in that the numbers interested in growing orchids are much larger than the number of growers. Presumably some of these are interested in learning with a view to getting involved with growing later. At least we hope this is the case.
We are certainly noticing a decline both in our numbers of growers and in members involved in surveys due to age and health.
The greatest number expressed an interest in general knowledge and we are relying on the Journal and the Website help to keep people interested and informed. Next was field trips, but we haven’t had that many that have attended field trips in in the last few years. Only 11 of those who expressed an interested in field trips are not interested in photography, the next item of interest, and only 10 people interested in photography were not interested in field trips. Not many of these share their photographs at monthly meetings. We are hoping to get members to make their photographs available for the identification guides.

It is pleasing that 58% are interested in conservation, thus supporting the efforts of our Conservation Officer.
Growing terrestrial orchids was next on the list; we hope that the tuber bank and the NOSSA Seed Kits are meeting the demand from members. Twenty-two of the 41 interested in growing orchids are interested in growing both terrestrial and epiphytic orchids. Only 8 of the respondents are bringing plants to meetings and a couple of others have not completed the survey. Of those interested in growing terrestrial orchids, one is a former grower and another is interested in growing them in situ at revegetation sites.
Thirty members expressed an interest in doing orchid surveys and three of these are interested in participating in the future, presumably when more time is available.
Citizen science is a new concept to many and came last in our list of interests. One who did not indicate an interest said he was monitoring orchids at a particular site; this has been taken as an interest. Surveys are certainly one form of citizen science and only 2 of those who indicated an interest in citizen science did not indicate an interest in being involved in surveys now or in the future. Thirteen of the 30 interested in surveys did not express an interest in citizen science. If these were included, interest in citizen science would be 43%.
Only seven members indicated an interest in all of the categories and one of these wants to keep in touch with the club and with old friends.
The Annual Spring Show in September 2015 was a particular success, largely due to the efforts of one our new members in promoting the show through local media and by other means. We also benefited from the donation of collections of growers who had decided not to continue with their collections.
Annual NOSSA Spring Show
NOSSA has continued to maintain a tuber bank that is available for members. A small number of our members are also members of ANOS Victoria, and have obtained tubers from their collection. This is hopefully contributing to the variety of terrestrial orchids grown by our members.
Working bees continued to be conducted in association with the Threatened Plant Action Group at Belair National Park for improving habitat for the nationally endangered Pterostylis cucullata (Leafy Greenhood), at Grange Golf Club to protect and monitor Pterostylis arenicola (Sandhill Greenhood) this being nationally vulnerable and locally endangered and on York Peninsula in conjunction with a local Friends group for the nationally endangered Caladenia intuta.
NOSSA has for many years used Australian Orchid Club (AOC) judges and knowledgeable members, who have all studied the ANOS judging rules, to judge orchids at NOSSA monthly meetings and shows. As the number of judges has fallen in recent years, judging training sessions have had to been discontinued. We wait in anticipation for a proposed ANOS judges correspondence course, as we have for more than 10 years. There are at least three AOC judges interested in the ANOS judging correspondence course. It is disappointing that ANOS Awards are still limited to Queensland, New South Wates and Victoria.
In summary, NOSSA continues to be active in many ways and these activities are working together to support each other.
Internationally, there is concern about the decline of orchids as seen in the resolutions passed in May 2016 at the International Orchid Conservation Congress Conference. In Australia, there are many orchid conservation projects in progress both in situ and ex situ.
The following are some examples of the varied work being done around the country by volunteers, orchid enthusiasts, ecologists, conservationists, academics and government departments.
From Victoria, work headed by Dr Noushka Reiter of the Royal Botanic Gardens Victoria has seen the propagation of threatened orchids from seed returned to their habitats.
And here in South Australia there are also various projects. Dr Noushka Reiter is also working with the South Australian Seedbank to help propagate four of our very threatened orchids. Members of the Native Orchid Society are assisting as also are Paul Beltrame (teacher) and students from Kildare College through the Orchid in Schools Project.
This week’s post is taken from the IUCN SSC Orchid Specialist Group Facebook post concerning Resolution decided upon at the final session of the International Orchid Conservation Congress Conference, held in May 2016 at the Kadoorie Farm & Botanic Garden, Hong Kong
It was posted by Michael Fay of Royal Botanic Gardens, Kew. He is also the Chair of the IUCN SSC Orchid Specialist Group. According to their website, “The Orchid Specialist Group is a global network of experts who volunteer their time and expertise to build a scientific and practical foundation for the conservation of orchids (Orchidaceae).”
(A list of the meanings of acronyms appears at the end of this post.)
Michael’s post follows
Here are the Resolutions from the final session of IOCC VI in Hong Kong:
Orchids are a flagship plant group with a high profile in human culture. They are known from all vegetated continents on earth but their occurrence reflects patterns in the global distribution of biodiversity and their intricate ecological associations, particularly with pollinators and mycorrhizal fungi, reflect sensitive ecosystem processes. Accordingly, orchids are indicators of ecosystem and climate health. Many orchids and their associated biota have been exposed to a variety of threats as a direct consequence of human-driven global change, with almost half of the ca. 27,000 known species now potentially at risk of extinction. Delegates of the IOCC support all efforts to research and mitigate these threats and secure environments on which orchids depend, and are committed to achieving meaningful conservation by recommending that:
The creation of orchid enhanced habitats is a priority for ecological restoration.
Enhanced in situ orchid protection requires the creation of orchid reserves. These will benefit a wide array of other species and biological communities and can be financed through various public and private sources.
The international and domestic wild plant trade is widely recognised by governments and civil society as a major threat to the persistence of many orchid species, and that its curtailment requires concerted government action and enforcement.
The propagation and cultivation of threatened orchids by small and local orchid enterprises should be supported for the sustainable production of orchids used in horticulture, medicine and food.
Orchid cultivation should be licensed and audited by government or other government-approved body through a national (or international) accreditation scheme that specifies adequate safeguards to ensure best practice. Propagated orchids should be traceable and distinguishable from wild orchids so as to minimise the risk of laundering wild plants.
National, regional and international networks should be established and strengthened for promoting in situ and ex situ orchid conservation.
The next generation of orchid taxonomists, ecologists and conservationists is nurtured through improved training, education, publicity and awareness-raising programmes.

Members shall strengthen the work of OSG by:
Facilitating and conducting national and global Red Listing of orchids, and contributing to the Sampled Red List Index (SRLI);
Monitoring and reporting on the illegal trade in orchids to national enforcement agencies and to TRAFFIC;
Reviving Orchid Conservation International as a vehicle for web-based education and channelling funding to orchid conservation programmes, along the lines of Birdlife International;
Embracing social media and other web-based interactive tools as dynamic and effective means of stimulating communication, raising awareness and building networks;
Using citizen science as an effective means of motivating individuals and amateur groups to record orchid occurrence (e.g. OrchidMap, iNaturalist) and help scale-up the collection of verifiable data;
Establishing and maintaining a global database of orchid reintroductions (including both successes and failures) and ex situ orchid collections that can be accessed and updated by members and which is linked to the IUCN Reintroduction Specialist Group;
Creating new sub-groups focusing on trade and molecular identification, to reflect important cross-cutting themes and challenges.
Thanks to Stephan Gale and Phil Cribb for producing the final version of these.
