'''The exploration of caves sheltering bats usually implies some degree of disturbance for the animals.''' |
|||
'''However, this disturbance can be clearly reduced by responsible practices.''' |
|||
'''Here are some guidelines on how to act according to the situation:''' |
|||
</big></center> |
|||
=== You are preparing the underground trip === |
|||
Then check the cave file on [http://www.grottocenter.org ''GrottoCenter'']<ref group=N>[http://www.grottocenter.org ''GrottoCenter''] is a collaborative database dedicated to speleology ; data is supplied by cavers on the principle of the wiki. ''GrottoCenter'' is managed by ''Wikicaves'' association. |
|||
[http://wikicaves.org ''Wikicaves''] and the ''GCLR'' work in partnership to educate cavers on underground environments , the impact of caving and to improve bat conservation.</ref> to see whether the presence of bats is mentioned. |
|||
If bats are present in the cave, you should adapt the number of cavers and the chosen period. |
|||
In doubt, get in touch with the regional bat correspondent. |
|||
=== You are at the cave entrance and find an information sign mentioning the presence of bats === |
|||
You should then choose to abort the exploration and turn to another cave if this happens to be in one of the periods when bats are significantly present. |
|||
=== You are in the midst of an exploration and meet a colony of a large group of bats (a few dozens, up to more than 1,000) === |
|||
You should then turn around whatever the season. |
|||
The panic within a colony could take a dramatic turn. |
|||
In the summer period, it can lead to the failure of mating, a major problem for animals which bear only one pup a year. |
|||
Repeated alerts in winter may eventually cause the animals’ death: their energy reserves may become exhausted with each new alert. |
|||
Please do inform the regional bat correspondent |
|||
You might return at a later period, the presence of the bats being seasonal. |
|||
=== You are exploring and find some isolated bats === |
|||
You may go on exploring and must comply with the following guidelines: |
|||
* Do not linger in the “inhabited” zone |
|||
* Do not stay right under the bat, even if not using a naked flame (the heat released goes up). |
|||
* Do use electric lighting on low settings and direct your light towards the ground while crossing the “inhabited” zone. Note that red light is significantly less disturbing for the bats. |
|||
* Limit the noise level as much as possible while moving in their clearly perceptible environment (metallic rattling, sound of footsteps, etc). |
|||
* In the narrow passages, double check the presence of bats. |
|||
* Finally one imperative rule to respect: if they start to move or bend their legs, then MOVE AWAY as fast as possible and in silence so that they regain their calm. |
|||
* If the number of bats is rather high (at least ten), make sure you inform the regional bat correspondent. |
|||
=== You are about to blow up obstructions or remove rocks === |
|||
The release of noxious fumes related to the use of explosives, the detonations, and the modification of the physical integrity of a cave can result in the death of the bats or the desertion of the site. |
|||
You should make sure there are no bats on the site when explosives are being used. |
