Ahimsa has an area of and is
contiguous with a much larger area of bushland, Pennant Hills Park, to the north. The vegetation is described as dry sclerophyll (hard leafed) bushland on
Sydney sandstone and is typical of the flora associated with the Northern Hills District of Sydney.
Condition As of 27 June 2000, the physical condition was good.
Modifications and dates An absorption trench was constructed in 1975 to contain surface run off from properties adjacent to
Ahimsa as the Trust was afraid that excessive run off would encourage weed growth. One cave has been altered and an attractive two-metre high Hawkesbury Sandstone
retaining wall was constructed many years ago near the path from the northern gate. Despite her wish that no plants foreign to it, even from other parts of Australia, should be planted several native plants not indigenous to Ahimsa have been planted. == Heritage listing ==
