Footnotes
1. Floristic composition of Brush Box forest varies substantially according to soil type and other
environmental factors. Hager and Benson refer to Forest Type 53 (Baur 1965) which includes all
Brush Box associations.
2. Brush Box on metasediments on the lower slopes of the coastal ranges appears to have affinities
with Floyd’s (1990a) Suballiance 18. This type is apparently restricted to Byron and Tweed Shires
and only small areas are reserved.
3. Largest areas mapped during the Byron Study were unreserved lands at Broken Head.
4. Areas of coastal Blackbutt at Broken Head are unreserved.
