The whole forest (802 ha) was surveyed for indigenous and exotic
plants over a period of some 18 years from 1982 to 2000.
A grid system called VICBOT, devised by A. Paget for flora surveys
divides Sherbrooke Forest into about 20 areas, 740 by 583 m.
these these areas is further subdivided into 25 cells, each 148 X 116 m.
Each cell is located by using compass bearings from a measured point on
tracks throughout the forest. Future surveys would probably use GPS.
In the centre of each cell a 7x7m. quadrant was surveyed using the
Braun-Blanquet abundance scale. The rest of the cell was then surveyed
using the same scale for an overall flora abundance.
Two person teams surveyed one, two, or three plots per session, filling
in a prepared form listing indigenous and exotic plants. In addition,
signs of forest animals were noted and comments made on the general
condition of the area surveyed. Survey results have been entered into a
data base so that specified flora and fauna can be readily located.
After the completion of the forest survey using the grid method, the
Friends undertook a survey of locations where waste water flows, from
adjacent houses and roads, generate problems for forest plants. One
result of this activity was the formation of "the Tuesday morning" group in 1999 to deal with an almost overwhelming growth of
Cestrum on and near the banks of Monbulk Creek at Nation Road. Now,
nine years later (2008), we are still treating regrowth of this
dreadful weed, and we probably still have a couple of years to go!!
But now it's a pleasure to see the return of the native plants.
Over the last three years "Water watch" surveys of two
creeks have been undertaken by the Friends in order to monitor the
health of these waterways.
