Why is it an offset?

The offset area has been established to offset the expansion of the Mugga Lane Resource Management Centre. The expansion required the removal of 9.8 hectares of vegetation, including white box-yellow box-Blakely’s red gum grassy woodland and derived native grassland ecological community (box gum grassy woodland). This community is listed as a critically endangered ecological community under the Commonwealth Government's Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and is also listed under the ACT Government's Nature Conservation Act 2014

What can I do in this reserve?

The offset area extends the Isaacs Ridge Nature Reserve. Recreational activities within Isaacs Ridge Nature Reserve include mountain bike riding, bushwalking and orienteering. Horse riding is permitted within the reserve, but access is restricted to designated trails. Horse riding is currently not permitted within the offset area.

The offset area is not located close to any of the main public access points into Isaacs Ridge Nature Reserve, nor does it contain any major access tracks from the reserve. Public access is likely to be limited due to these factors. No new tracks are planned into or within the offset area and public access will not be promoted.

Low impact activities such as walking and orienteering are however, permitted within the offset area. Dogs are prohibited in the offset area.
