Board profile - Owen Love

Owen Love

Board member, South Australian Murray-Darling Basin Natural Resources Management Board

Mr Love made his career in theatre and the arts as a playwright and toured Australia with his  own play for eight years. Raised on 160 acres belonging to his grandfather on the banks of Lake Alexandrina, Mr Love’s formative years were all about soil, land, plants, animals and water.

Having grown up in Wellington, Mr Love has a solid understanding of the way the entire river system operates: the wildlife, flora, the overlapping of land, water, community, and the changes impacting on them.

Mr Love runs workshops in schools for students and teachers in the art of storytelling. Communication and sharing stories is critical in understanding and describing the natural world to children who live in the suburbs and are unfamiliar with the larger system.

Board profile - Deana Mildren

Deana Mildren

Board member, South Australian Murray-Darling Basin Natural Resources Management Board

A passion for sustainable farming brought Deana and her husband Greg to purchase a small farm near Tungkillo.  Her small business background enables them to successfully produce and market their olives and continue developing their plan to maintain and improve the sustainability of their farm through balancing production needs with those of the environment.

As chair of Tungkillo Landcare Group, Deana has led the group through planning and implementing numerous projects throughout the region including hosting Guilford grass field day, plant propagation workshop, bird watching mornings, feral olive control, soil pit workshop and gaining several small and medium grants to improve local patches of remnant.

With two young girls, Deana has particular interest in developing children’s love of and connection with their environment and has been proactive in helping her local schools develop programs within and outside of the classroom. This has culminated in an annual visit to a local remnant where children gain first-hand knowledge of what their backyard may have looked like years ago and why biodiversity is critical in maintaining sustainable farming.
