The comments below provide insight into the proposed
development of an Order to protect more than recreational Karst values in our
forest district.
Letter October 13th 2008
Subject: Development of a Draft South Island Forest District
GAR Karst Order
Hi Paul and All,
There are a number of ecological and management issues I would like to rise with
regard to protection for karst ecosystems and related resources. Some of these
issues include well-defined definition for problematic terminology, monitoring
and enforcement.
Various Ministry staff (other than SIFD) has stated that definition for Karst
Cave for example, is not advised because they are always changing. They assert,
definition for Karst Cave may be challenged in court therefore, its best to
allow a judge to decide resource feature criteria by simply referring to a
dictionary. These types of comment infer reactionary strategy as opposed to
meaningful legal directive to avoid impact to karst systems and related forest
resource values.
An element of a karst system for example often includes non-karst caves,
hydrologic and biologically connected to surface karst openings. The absence of
definition for terms such as, Karst Cave threatens the opportunity to practice
ecosystem-based management, and reasonable protection for key public
environmental resource values.
In my view, well-defined criteria-based definition is necessary to meet the
public expectation for potable water supply, government objectives for
ecosystem-based management of forest resources, and provide clarity for forest
workers, land managers and timber companies.
The BC Ministry of Forests, Recreation Manual, under Chapter 13, Cave/Karst
Management, outlines Ministry responsibilities, provides longstanding inventory
and assessment methology, definition and guidance.
As the new SIFD Manager Paul, could you provide some sort of a time frame for
development of a Draft Karst Order, and share prospective on stewardship and
legal requirement necessary to protect the natural function of karst ecosystems
(including any contributing non-karst recharge zone). (The Drinking Water
Protection Act for BC provides specific wording to protect a wells recharge
area, but does not provide specific terms to protect the recharge area for
karstic springs).
To assist in development of a karst order, I've attached a recent scientific
paper which describes how the epikarst zone stores and releases groundwater
through karst systems, sustaining perennial flow, resurfacing on slopes
(epikarst springs). The paper also provides insight into the usefulness of
ground penetrating radar as a management tool to prevent impact to near surface
voids, streams and underground drainage pathways (conduits).

Thanks Reid,
As usual, you are able to look below the surface on these issues.
Proactive definition is essential to ensuring adequate protection of caves,
Karst and epikarst but also to ensure due diligence around public safety and
water protection. That should not be the purview of a judge unless she/he is
assessing damages where government policy (or lack therein like Walkerton) has
already caused harm.
Judges, to my knowledge receive no specific training is karst/cave protection or
their larger role in the environment.
In our earlier meeting with Minister Penner and senior staff, we made it clear
that proper legislation was not just necessary for cave/karst/environmental
protection, but for public safety (as in Walkerton). Accurately defining terms
is an essential first step in appropriate legislation.
Thanks again Reid,
Scott
