Site description:
Englebrook Reserve contains stringybark (Eucalyptus obliqua) open forest a community which has been exploited in the Mount Lofty Ranges in the past (< 1% of the original extent remains). Two drainage lines flow through the reserve, one contains excellent examples of wetland bog vegetation including several species of conservation significance.

Conservation measures taken:
Conservation measures - National Trust Reserve (Heritage agreement no. HA 514). Scientific research - Seaman (2002d), and Conservation Strategies. Also on the Register of the National Estate and working bees are held twice per month to remove environmental weeds. Vegetation condition mapping has been done in the past and is planned for the near future. Current conservation education - Interpretive brochure available and regular tertiary student working days (weed control) are undertaken.
Management authority and jurisdiction:
National Trust of South Australia.
