In a major coup for organisers, passionate landscape architect Costa Georgiadis will be a special guest at the 20th Wimmera Biodiversity Seminar in Horsham next month.

In announcing Costa's inclusion on the program, organising committee LaVergne Lehmann said Costa would bring his irresistible and infectious enthusiasm for biodiversity and working with Mother Nature.

The seminar is in Horsham Town Hall on Thursday September 7. The day and evening program includes presentations on native food production, the Wimmera Mallee Pipeline and the future of Landcare. It also includes a tour to West Wail Flora and Fauna Reserve, dinner and an intimate solo concert with Australian singer songwriter Neil Murray.

Costa is the host and co-creator of Costa's Garden Odyssey on SBS. In 2013 he became the host of the one of ABC's most iconic television programs, Gardening Australia.

He travels extensively to work with schools, TAFE colleges and universities, industry groups and communities to promote food and food security, waste and recycling, regenerative agriculture, and water and soil.

"Costa encourages people to challenge themselves and be innovative when it comes to their natural environment, whether it be for the purpose of growing their own food, looking after their precious water and soil resources or being innovative about reducing waste," La Vergne said.

"He brings passion and charm to everything he is involved in, and sees things through very enthusiastic eyes. We are rapt to have him as part of our seminar and our 20th year celebration."

Costa adds to an already packed program, which has the theme Back to the Future. Other guests include Landcare stalwart Rob Youl, OAM, and founding seminar organising committee members. The seminar will also include the official launch of Wimmera CMA's Wimmera Glovebox Guide to Wimmera Frogs…rivers, creeks and wetlands and a memorabilia display from the past 20 years.
