MINIMAL IMPACT CAVING CODE
Introduction
The need for a Minimal Impact Caving Code (MICC) has evolved
over many years as cavers have realised the impact that they
have on caves. That impact is so diverse and varied that it has
become necessary to devise a caving code that ensures that
cavers are aware of the measures that are necessary to reduce
their impact on caves.
To those of you who have just become Philippine Caving Society
(PCS) members it is important that you
understand that a MICC IS necessary because cavers are one of
the major sources of damage to caves. Read the MICC carefully
and apply it to all of your caving - it will not completely stop
cavers damaging caves but it will certainly reduce their impact
on the cave environment. This MICC was devised by cavers FOR
CAVES - please assist the Philippine Caves by using these
simple MIC techniques.
General
This code is divided into two sections. One relating to the
exploration of a newly discovered cave or section of cave and
the other relating to general cave visitation.
The following practices may fall into both sections and may be
modified depending on the type of cave being visited. It should
be stated that we are discussing here a code which will ensure
that cavers have a minimal impact on the cave they are visiting.
In many instances the practices may not apply as the impact that
cavers have, may be minuscule, compared to the impact of
flooding of the entire cave, for example. These practices are
generally intended to apply in caves where cavers are likely to
have a detrimental impact on the cave purely by entering the
cave.
In-cave marking refers to the use of a variety of materials to
define tracks, routes and barricades in a cave. These measures
should be taken to protect sensitive areas, confine caver foot
damage, make cavers aware that a sensitive (it may be an
unobvious cave animals' territory) area exists.
THERE ARE NO EXCEPTIONS TO THIS CODE - SURVEYORS,
PHOTOGRAPHERS, SCIENTISTS, EXPLORER'S ETC ARE ALL SUBJECT TO
THIS CODE.
General Cave Visitation
1. Remember EVERY caving trip has an impact. Is this trip into
this cave necessary? If it is just for recreation, is there
another cave that is less vulnerable to damage that can be
visited? Make this assessment depending on the purpose of your
visit, the size and experience of the proposed party, and IF THE
TRIP IS LIKELY to damage the cave.
2. Where possible the party leader should have visited the cave
previously and hence should be aware of sensitive features of
the cave, the best anchor points, and generally reduce the need
for unnecessary exploration.
3. Cave slowly. You will see and enjoy more, and there will be
less chance of damage to the cave and to yourself. This
especially applies when you are tired and exiting a cave.
4. If there are beginners on a trip, make sure that they are
close to an experienced caver, so that the experienced caver can
help them when required, e.g. in difficult sections. Ensure that
the party caves at the pace of the slowest caver.
5. Keep your party size small - 4 is a good party size.
6. Cave as a team - help each other through the cave. Don't
split up unless impact is reduced by doing so.
7. Constantly watch your head placement AND that of your party
members. Let them know before they are likely to do any damage.
8. Keep caving packs as small as possible or don't use them in
sensitive caves or extensions.
9. Ensure that party members don't wander about the cave
unnecessarily.
10. Stay on all marked or obvious paths. If no paths are marked
or none is obvious - define ONE!
11. Learn to recognize cave deposits or features that may be
damaged by walking or crawling on them.
Examples are:- Drip Holes, Stream Sediments, Paleo soils, Soil
Cones, Crusts, Flowstone, Cave Pearls, Asphodilites, Bone
material, Potential Archaeological sites, Cave Fauna, Coffee &
Cream, Tree Roots
12. Take care in the placement of hands and feet throughout a
cave.
13. Wash your caving overalls and boots regularly so that the
spread of bacteria and fungi are minimized.
14. If a site is obviously being degraded examine the site
carefully to determine if an alternative route is possible. Any
alternative route MUST not cause the same or greater
degradation than the currently used route. If an alternative
is available suggest the alternative route to the appropriate
management authority and report the degradation.
15. Carry in-cave marking materials while caving and restore any
missing markers. Tape off sensitive areas you believe are being
damaged and report the damage to the appropriate management
authority.
16. If it is necessary to walk on flowstone in a cave remove any
muddied boots and or clothing before proceeding OR DON'T
PROCEED! Sometimes it is better to assess the situation and
return at a later date with the appropriate equipment.
17. Treat the cave biota with respect, watch out for them, and
avoid damaging them and their "traps", webs, etc. Also avoid
directly lighting cave biota if possible.
18. If bone material is found on existing or proposed tracks it
should be moved off the track to a safer location if at all
possible. Collection should only be undertaken with appropriate
permission.
19. If you eat food in a cave ensure that small food fragments
are not dropped as this may impact the cave biota. One way is to
carry a plastic bag to eat over and catch the food fragments.
This can then be folded up and removed from the cave.
20. Ensure that all foreign matter is removed from caves. This
includes human waste. If long trips are to be made into a cave
ensure that containers for the removal of liquid and solid waste
are included on the trip inventory.
21. When rigging caves with artificial anchors, e.g. traces,
tapes, rope etc, ensure that minimal damage occurs to the anchor
site by protecting the site. For example protect frequently used
anchors, e.g. trees, with carpet, packs, cloth, etc. Bolts
should only be used where natural anchors are inappropriate.
22. CAVE SOFTLY!
New Cave or Extension Explorations
1. The existing microbiology of the new cave, both fungi,
bacteria, and a world of protozoa, will almost certainly be
irreversibly contaminated on the first trip into the cave! If
you consider cave microbiology has not been investigated in the
area of this new cave, if cave microbiologists are available,
then please consider including them on initial explorations so
that they may collect uncontaminated samples.
2. Do not enter the new area if you do not have the equipment
required to undertake the minimal activities. Surveying
equipment and in-cave markers.
3. The minimal activity should be in-cave marking and surveying.
Not purely exploration.
4. Ensure that all alternative routes are examined, by
completing the cave survey, prior to crossing sensitive areas.
It may not be necessary to enter some areas as they can be
by-passed.
5. Having determined that a sensitive area is to be crossed it
should ALWAYS be marked. Reduce future damage by defining a
distinct, minimal width track.
6. Discuss in-cave marking within the party and ensure that all
ideas are evaluated before marking is undertaken.
7. CAVE SOFTLY!
