SUGGESTED PROTOCOL FOR LAND CLEARING
 

4.11 The wildlife control operator should pay particular attention to observing for the presence of burrows or tracks in leaf litter adjacent to rock, brush piles, log piles or other habitat features.

Removal of arboreal wildlife

4.12 Removal of arboreal wildlife should be accomplished initially by thorough trapping efforts. Appropriate use of traps will minimize the risk of injury to wildlife collected by more direct methods, or at the time of clearing.

4.13 Trees contain a variety of different habitats for wildlife including cavities in the limbs and primary trunk, under bark, as well as foliage and upper limbs. All such habitats should be thoroughly explored for the presence of wildlife.

4.14 It is the responsibility of the wildlife control operator to ensure that appropriate methods are used to retrieve wildlife from arboreal habitats such that the risk of injury to the animals is minimized.

4.15 Trees containing wildlife must not be felled until all reasonable efforts have been made to remove wildlife.

4.16 Habitat trees of high importance should be felled last, after surrounding less important vegetation has been cleared to allow easy access of special equipment (such as cherry pickers), traps, and to allow unhindered lowering of cavity-bearing limbs. It is not acceptable to fell or push over cavity-bearing trees without first removing wildlife, due to the high risk of fall and/or crushing injuries to wildlife inhabiting such trees.

4.17 Cavity-bearing limbs can be cut and lowered gently to the ground using a variety of techniques, such as the use of cranes or special rigging. Prior to any intervention, exit holes should be plugged with rags or newspaper to prevent escape of wildlife during cutting or lowering of cavity-bearing limbs.

Preservation of tree cavities and other habitat features.

4.18 Whenever possible, the integrity and structure of tree cavities contained in trees which are to be removed should be preserved. These should be relocated to appropriate habitat retained on the site, or to appropriate habitat close to the site.

4.19 The wildlife control operator should aim to ensure that there is no net loss of important habitat features, such as tree cavities.

4.20 Other valuable habitat features such as large fallen logs, log piles, rock piles or outcrops, etc. should be preserved as much as possible, and translocated and re-established at appropriate habitat close to their site of removal.
