6.3 Fauna species reservation analysis

6.3.1 Methods


A reservation analysis has been undertaken to assess the extent to which terrestrial vertebrate species in the Central Highlands are protected in the reserve system.
Using data from the Atlas of Victorian Wildlife, both formal survey and incidental records were intersected with existing land tenure to calculate the total proportion of records for each species in each land tenure category (see Table 6.3). Categories used were Reserve, Non-Reserve and Partially Reserved areas (see table footnote for explanation). Table 6c also indicates whether the majority (>50%) of the species’ known range is within the Central Highlands.
The results will tend to underestimate the level of protection provided to species by the reserve system because it has had fewer formal surveys.
The results should be considered in conjunction with the information on threatening processes. Many threatening processes operate across reserve and off-reserve areas and other measures are in place, in addition to reservation, to provide protection at the species level.

6.3.2 Results and discussion


The results of the assessment are presented in Table 6.3. Most species which have their major occurrence in the Central Highlands appear to have populations sampled to a moderate to high degree by the reserve system. The exception is the Glossy Grass Skink, for which only 11% of known records occur in reserves.

Notes: (a) Reserves include National Parks and Special Protection Zones.

(b) Partially Reserved areas include Special Management Zones and Code of Forest Practice exclusion areas.

(c) Most records from within the Non-Reserve category are from private land.

(d) Only records post 1970 and with an accuracy of one minute or better were used in this analysis.

(e) Records of individuals over water bodies (mostly birds and bats) have been omitted.
