Cave size and depth are important because deeper caves may provide more protection from ambient surface fluctuations in temperature and humidity.

AbstractPrioritizing caves known to contain endangered
karst invertebrates in central Texas is more challenging than
one may think. Here, we outline a strategy to achieve this goal
while thinking of what is best for these species including
addressing future impacts from climate change, and what works
for landowners that are bound to permit restrictions. For
example, there are two entities in the Austin, Texas area that
hold regional Section 10(a) (1)(B) incidental take permits
issued by the U.S. Fish and Wildlife Service. When developing
the Habitat Conservation Plan for one of these permits several
years ago, they listed several caves that they would either
acquire or establish management agreements for. Since that
time, they have acquired thousands of acres. Some of the caves
listed on their permit occur on these lands. However, there are
other newly discovered caves on these lands that contain
endangered karst invertebrates that are not listed on their
permit. Also, some of the caves that are listed on their permit
are surrounded by development. This begs the question of which
caves should they focus on for long-term preservation? Should
they be limited to what their permit says or take a wider
approach and look at what is best for the species while
considering new cave discoveries? To answer this question from
a species perspective, several aspects of these caves should be
assessed including but not limited to the cave depth, cave
size, species diversity and abundance, and the amount of
development etc. around these preserves. Cave size and depth
are important because deeper caves may provide more protection
from ambient surface fluctuations in temperature and humidity.
This approach should provide a more holistic pathway to
long-term karst invertebrate conservation. By assessing what is
best for the species and acknowledging new cave discoveries,
perhaps minor amendments could be made to 10(a)(1)(B) permits
that would provide higher species benefits.
