    I work at Mount Annan Botanic Garden in south west Sydney with a dedicated team of horticultural scientists who are steadily building on our knowledge of Australian native plants. We work under the guidance of Dr Cathy Offord to ‘domesticate’ species such as flannel flowers, waratahs and most recently, the Wollemi Pine, by selecting suitable genetic lines and researching their requirements in cultivation. The group also plays an integral role in the conservation of plant species native to NSW by storing seeds or living plants and collecting valuable biological information about each species.
 

Seed storage and research at Mount Annan has recently been given a boost through the SeedQuest NSW program, which aims to collect, store and research seed of 250 species each year. SeedQuest is a partnership with the Millennium Seed Bank Project of the Royal Botanic Gardens Kew in the UK (also featured in Sarah Ashmore’s Wisenet article in April 2005).
 

I’ve been working as a researcher in the SeedQuest project for about 18 months, with the task of improving germination, breaking dormancy and working out the lifespan of seeds stored at the

 NSW Seedbank. I feel very lucky to work with our native flora and am constantly amazed at the relative scarcity of information about species literally on our doorstep, our roadsides and in our parks and reserves.
 

My job is a natural extension of my long-held passion for plants, particularly Australian native plants. I was lucky to have parents who took my four sisters and I bushwalking in the Royal National Park and an extended family who encouraged our curiosity about natural things. On one memorable occasion, my science-teacher uncle helped us microwave pine cones to extract the winged seeds, and then toss the seeds from the highest chair we could stand on to watch them ‘helicopter’ to the ground. My nana, the owner of the microwave, was very tolerant… It turns out that seeds played a special role in our nana’s family, as her distant ancestors were American pilgrims who sewed seeds into the hems of their dresses to keep them safe as they toiled along the Oregon Trail.
 

After studying physics and chemistry (no biology!) at high school, I began a Horticultural Science degree at the University of Sydney. I gained a new appreciation for the complexity of plants and took subjects on native plants to supplement my knowledge of traditional horticultural crops. I investigated the horticultural potential of an Australian native pea (Swainsona sejuncta) under the joint supervision of staff at Mount Annan and the University for my Honours project. My task was to work out whether this beautiful but alarmingly robust and prolifically seeding species had significant weed potential. Even with the data behind us and recalling the phrase “One year’s seeding, seven years’ weeding”, it’s no easy job convincing the horticulturalists that the colourful pea is not the best addition to their garden!

    I then worked as a research assistant in a mycology lab for a year and decided that I wanted to experience the full spectrum of research, from planning to collecting and analysing data and communicating results. So I returned to university, where my Honours supervisors offered me the opportunity to do a PhD study on waratahs. Commercial flower growers were concerned about a problem called “bract browning”, where the bracts surrounding the waratah inflorescence turned brown prior to harvest. After almost four years, I could explain to growers that bract browning was similar to sunburn, and
could be reduced simply by shading the waratah plants before the flowers opened in spring. The physiological explanation for bract browning begins with light damage (chronic photoinhibition) leading to pigment loss, probable oxidative damage to other cell components and eventually, cell death and necrosis seen as browning.
 

In my work and studies, I’ve had great support and encouragement from my (mostly female) supervisors and have been a mentee and

 mentor in formal programs. I’m keen to show this kind of support to others and to encourage people to take make the most of opportunities that come their way; so I’ve become a Spokeswoman for Mount Annan. All NSW public sector agencies are required to operate a Spokeswomen’s Program with the aim of identifying and acting on matters affecting women, providing information and professional development opportunities and increasing gender equity in organisations. This has given me the opportunity to meet great women throughout NSW who are passionate about women’s issues and conservation (Mount Annan Botanic Garden, along with Mount Tomah and the Royal Botanic Gardens Sydney are all part of the NSW Department of Environment and Conservation).
 

Being a spokeswoman at work and a member of Wisenet, and coming from a large family with four sisters (at present, one engineer, one camera person, one artist and one determined high school student), reassures me that I’m connected to a network of strong, intelligent and caring women. I’m optimistic that by joining together and supporting each other we can really make a difference in our world!
